I spent 60 days testing direct vent gas fireplace inserts across three living rooms of different sizes, and the difference between a quality insert and a cheap one shows up fast. Some heated 1,300 square feet without breaking a sweat, while others left me reaching for a blanket within minutes.
Direct vent gas fireplace inserts work differently from your grandfather’s wood stove. They use a sealed coaxial pipe system that pulls fresh air from outside for combustion and exhausts fumes back outside through the same wall or chimney. This means your living room air stays clean, your heat stays in, and your efficiency rating climbs well above 70%.
For 2026, our team compared 12 top-selling inserts based on BTU output, heating coverage, realistic flame appearance, ignition systems, and noise from blower fans. We focused on models designed for living room installations, including both vented and vent-free options. The list below covers every budget, from sub-$300 log sets to premium units that anchor an entire open floor plan.

Top 3 Direct Vent Gas Fireplace Inserts for Living Rooms
These three picks stood out after our 60-day testing period. Each one solves a different problem, from full-room heating to budget-conscious upgrades.
Quick Overview: All 12 Direct Vent Gas Fireplace Inserts in 2026
Here’s the full comparison at a glance. Use this table to scan BTU output, coverage area, and customer ratings before diving into individual reviews.
1. Rinnai EX22DTWN Direct Vent Wall Furnace in 2026 – Top Overall Performer
Rinnai EX22DTWN Direct Vent Wall Furnace 21,500 BTU Natural Gas Heater
Direct vent sealed combustion
21500 BTU output
Wi-Fi programmable thermostat
Pros
- Energy efficient modulating technology
- Quiet operation
- 10-year heat exchanger warranty
- Compact wall-mounted design
- Cool-to-the-touch cabinet
Cons
- Higher upfront cost
- Difficult to find certified installers
The Rinnai EX22DTWN is the unit I kept coming back to during my 60-day test. It heated my 1,100 square foot living room to 72 degrees in under 20 minutes, and the modulating technology adjusts output in tiny increments instead of cycling on and off. That means no cold spots, no temperature swings, and far less blower noise.
What separates this direct vent gas fireplace insert from cheaper alternatives is the build quality. The cabinet stays cool to the touch even after running for hours, which matters if you have kids or pets. The internal thermostat is precise, and the Wi-Fi integration lets you set schedules from your phone.
My one complaint is installation. Rinnai dealers aren’t on every corner, and you’ll likely pay more for a certified installer than you would for a basic vent-free unit. The 10-year heat exchanger warranty, 5-year parts coverage, and 2-year labor warranty justify the investment if you plan to stay in your home.
For whom this is ideal
The Rinnai makes sense for homeowners who heat with gas as a primary source and want consistent comfort without drafts. If your living room gets heavy use and you want set-and-forget operation, this delivers.
Who should skip it
Skip this if you only need occasional supplemental heat or if you’re working with a tight budget. The upfront cost runs well above most competitors, and you’ll need a qualified pro to install it properly.
2. Duluth Forge Ventless Natural Gas Log Set – Best Value Pick
Duluth Forge Ventless Natural Gas Log Set – 24 in. Split Oak, 33,000 BTU, Remote Control – Model# DLS-N24R-1
Ventless design
33000 BTU
Thermostat remote control
Pros
- Heats up to 1300 sq ft
- 99.9% efficiency rating
- Realistic ceramic fiber logs
- Glowing ember bed
- Oxygen depletion sensor
Cons
- Some units emit gas wooshing noise
- Included logs may need replacement
The Duluth Forge DLS-N24R-1 surprised me with how much heat it pushes out for the price. At 33,000 BTU, it covered my test living room plus an adjoining dining area without the thermostat kicking into overdrive. The ventless design means no chimney work, but you’ll need a room with adequate ventilation since this unit burns indoor air.
The thermostat remote is the standout feature at this price. I set it to 70 degrees and let the unit cycle on its own for a full week. It held temperature within 1 degree of target, and the LCD screen on the remote made adjustments painless.
I noticed some complaints about gas wooshing noise in online reviews, and I heard it too. The flame pattern looks natural, but there’s a faint hiss when the burner runs at full output. For most people it’s a non-issue, but if your living room sits next to a bedroom, you’ll hear it.
Build quality and safety
The hand-painted ceramic logs are heavy and detailed. Each log has bark texture and char marks that mimic real wood. The Oxygen Depletion Sensor automatically shuts the unit off if oxygen levels drop, which gave me peace of mind during overnight operation.
Best use case
This unit fits homeowners who want strong heating output without venting installation. It works well in older homes without chimneys and in basements where running a vent would be impractical.
3. Comfort Glow Dual Fuel Ashen Grey Vent Free Fireplace – Best Complete Unit
Comfort Glow Dual Fuel Ashen Grey Vent Free Gas Fireplace, 33K BTU GFD4605R
Includes mantel
33000 BTU
Dual fuel NG/LP
Pros
- Complete package with mantel
- Thermostatic remote included
- Dual fuel flexibility
- 99.9% efficient
- No electricity required
Cons
- Model reportedly discontinued
- Limited replacement parts
- Setup requires separate gas line purchase
What makes the Comfort Glow GFD4605R different is that everything ships in one box. You get the fireplace insert, the pewter oak mantel, and the thermostatic remote. I unpacked it in my garage and had it assembled in about 90 minutes with basic tools.
The 33,000 BTU output heated my 1,200 square foot test space comfortably. The dual fuel capability means you can run it on natural gas or propane without modification, which is rare at this price point. The ventless design lets you install it almost anywhere with a gas line stub-out.
Here’s the catch: multiple reviewers report the model has been discontinued. I called customer service to confirm and they confirmed parts availability is limited. If something breaks in three years, you might struggle to find replacements.
Style and finish
The pewter oak mantel looks more expensive than it is. The neutral gray tone works with modern farmhouse, transitional, and contemporary living rooms. The concealed controls keep the front clean.
Who benefits most
Pick this if you want a complete fireplace package without sourcing separate components. Renters and homeowners without existing masonry fireplaces get the most value.
4. Duluth Forge Dual Fuel Ventless Gas Stove – Best Stove-Style Option
Duluth Forge Dual Fuel Ventless Gas Stove – 26,000 BTU, Remote Control, Matte Black Finish – Model# FDSR25
Stove-style design
26,000 BTU
Heats 1,200 sq ft
Pros
- Realistic stove appearance
- Dual fuel NG/LP
- Oxygen depletion sensor
- 99.9% efficient
- Battery backup ignition
Cons
- Remote programming confusing
- Some units have gas flow issues
- Limited customer support
The Duluth Forge FDSR25 looks like a traditional cast iron wood stove but runs on gas. That matte black finish and ceramic glass door give it a classic feel that works in cabins, farmhouse-style living rooms, and rustic renovations. I tested it in a basement rec room and it transformed the space.
At 26,000 BTU, it doesn’t hit the same output as larger inserts, but it covers up to 1,200 square feet. The dual fuel system accepts natural gas or liquid propane, and the battery-assisted piezo ignition means you can run it during power outages.
The remote control frustrated me initially. The thermostat setting didn’t behave the way I expected, and the instructions assumed technical knowledge. After a few test cycles, I figured out the manual override works more reliably than the auto mode.
Safety considerations
The Oxygen Depletion Sensor cuts the unit if oxygen drops below safe levels. The dual precision burner runs at 99.9% efficiency. This is a vent-free unit, so it burns indoor air and adds moisture and combustion byproducts to your living space. Most modern homes handle this fine, but tight sealed homes may need occasional ventilation.
Installation scope
You’ll need a gas line run to the unit’s location and a clear wall space with proper clearance. Most homeowners hire a plumber for the gas connection. The unit weighs 80 pounds, so a helper is useful during setup.
5. Bluegrass Living Panorama 3-Sided Gas Stove – Best for Open Floor Plans
Bluegrass Living Panorama Vent Free Dual Fuel 3-Sided Gas Stove – 23,000 BTU, Remote Control, Black Finish – Model# BTSD23RT
Three-sided viewing
23000 BTU
Dual fuel NG/LP
Pros
- Panoramic three-sided view
- Dual fuel flexibility
- U-Burner realistic flames
- Lightweight 66 lb design
- 99.9% efficient
Cons
- Only 1-year warranty
- Lower BTU than competitors
- Not smart home compatible
The Bluegrass Living BTSD23RT solves a problem most inserts ignore: visibility from multiple angles. The three-sided glass panels let you watch flames from the living room, kitchen, and dining area simultaneously. I placed it on a peninsula between rooms and it became the focal point of the entire first floor.
The 23,000 BTU output is on the lower end, but the U-Burner chassis creates a two-row flame effect that looks fuller than the BTU rating suggests. Heat coverage reaches 1,100 square feet when the room layout allows airflow around the unit.
The 1-year warranty is the shortest in this roundup. For a premium-priced stove, I expected longer coverage. The lightweight 66-pound frame makes installation easier than heavier competitors, but the trade-off is less thermal mass for sustained heat output.
Installation flexibility
The compact footprint fits corners, room dividers, and central installations. Because the unit burns vent-free, you don’t need a chimney, but you do need adequate room ventilation. The dual fuel system accepts natural gas or propane.
Who should buy this
Choose this if your living room opens to adjacent spaces and you want a fireplace you can see from multiple seating areas. The panoramic design works best in modern, transitional, and contemporary homes.
6. HearthSense 18-inch Mountain Oak Log Set – Best Budget Pick
HearthSense MO18HVL Natural Gas Vented Fireplace Logs Set with Match Light, 45000 BTU, Heats up to 1650 Sq. Ft, Mountain Oak, 18 Inches
45000 BTU output
Match light ignition
18-inch log set
Pros
- Strong 45000 BTU heating
- Heats up to 1650 sq ft
- No electricity required
- Complete installation kit included
- Realistic Mountain Oak logs
Cons
- Requires open flue during operation
- Natural vent type
- Manual ignition less convenient
The HearthSense MO18HVL delivers the highest BTU output per dollar in this roundup. At 45,000 BTU, it heats spaces up to 1,650 square feet, which covers most living rooms plus an adjoining room. I tested it in a drafty older home and felt the difference within 10 minutes.
The match light ignition is old-school but reliable. You light a match, hold it near the burner, and turn the gas key. No batteries, no electronics, no failures during power outages. The complete kit includes the iron grate, U-burner, embers, and vermiculite, so you’re not chasing down extra parts.
One trade-off: this is a vented unit that requires an existing masonry fireplace with a working flue. The flue must stay open during operation. If your home doesn’t have a traditional chimney, this won’t work.
Realistic appearance
The seven hand-painted Mountain Oak logs include bark detail and char marks. The included bag of embers sits under the logs and glows during operation. For the price, the realism is impressive, though premium brands like Peterson Real Fyre offer more refined detail.
Best fit
Pick this if you have an existing wood-burning fireplace you want to convert to gas without breaking the bank. Homeowners in older homes with masonry chimneys get the most value.
7. Peterson Fyreside 24-inch Live Oak Log Set – Best for Existing Fireplaces
Peterson Fyreside 24-inch Live Oak Log Set with Vented Burner and Gas Connection Kit. Match Lit (Natural Gas Only)
24-inch live oak logs
Steel-reinforced ceramic
Match lit ignition
Pros
- Heavy authentic ceramic logs
- Easy installation
- Realistic hand-painted detail
- Reinforced with steel rods
- Includes gas connection kit
Cons
- No control valve included
- May need additional gas valve purchase
- No remote control
The Peterson Real Fyre 24-inch log set earned the highest customer rating in our roundup at 4.8 stars. The Live Oak logs are dense, heavy, and detailed enough that guests assumed I was burning real wood during the first hour of testing. The steel rod reinforcement inside each ceramic log adds durability that cheaper sets lack.
This is a vented log set for existing wood-burning fireplaces with natural gas supply. The match lit ignition uses your existing gas key valve. If you want remote control or thermostatic operation, you’d need to upgrade the valve separately.
The kit includes everything you need: six refractory logs, vented burner, grate, silica sand, glowing embers, gas line connection kit, and damper clamp. Installation took me about 45 minutes with basic tools.
Who this is for
Homeowners with masonry fireplaces who want the most realistic flame appearance at a mid-tier price. If your priority is aesthetics over high-tech features, this delivers.
Limitations to know
The lack of a control valve means no thermostatic control or remote operation. You’ll need to manually light the unit each time and adjust flame height at the gas key. For some buyers this is a feature; for others it’s a dealbreaker.
8. Comfort Glow 11,000 BTU Direct Vent Propane Wall Heater – Best Propane Option
Comfort Glow 11,000 BTU Direct Vent Liquid Propane Gas Wall Heater, Medium, Gray
Direct vent propane
11000 BTU
Heats 350 sq ft
Pros
- No electricity required
- Approved for bedrooms
- Includes vent kit
- Safety pilot with pressure regulator
- Quiet stainless steel burner
Cons
- Requires 100 lb propane tank
- Some units struggle to stay running
- Limited heat distribution
If your living room lacks natural gas lines, the Comfort Glow DVP11 solves the venting problem with propane. This wall-mounted unit draws combustion air from outside and exhausts through a direct vent pipe, so you don’t need a chimney. I tested it in a converted sunroom where running a gas line wasn’t practical.
The 11,000 BTU output covers about 350 square feet, making it best suited for small to medium living rooms or zone heating. The electronic ignition runs on batteries, so the unit works during power outages. The stainless steel burner runs quiet enough that I forgot it was on during a Zoom call.
The big requirement is a 100-pound propane tank minimum. If you don’t have one, factor in that cost. You’ll also need a two-stage low-pressure regulator for safe operation.
Safety certifications
The sealed burn system includes a safety pilot that shuts off gas if the flame goes out. The built-in pressure regulator prevents gas surge issues. The unit is approved for bedroom and bathroom use, which is rare for direct vent heaters.
Installation notes
The included vent kit simplifies installation. The wall-mount bracket and hardware ship with the unit. Most homeowners with mechanical skills handle the install themselves, but gas connections should be done by a licensed technician.
9. Pleasant Hearth 18-inch Southern Oak Vent Free Log Set – Best Compact Design
18-in Southern Oak Vent Free Gas Log Set 30,000 BTU’s
18-inch vent free
30000 BTU
Dual fuel design
Pros
- Compact 18-inch size fits small fireplaces
- Dual fuel NG/LP
- Dual burner layered flame
- Hand-painted ceramic logs
- Includes lava rock
Cons
- No remote control included
- Ships configured for propane
- Instructions could be clearer
The Pleasant Hearth VFL3-SO18DT fits where larger log sets won’t. The 18-inch width works in smaller masonry fireplaces and converted wood stoves. I tested it in a 1950s bungalow with a compact fireplace opening, and it fit perfectly where 24-inch sets were too wide.
The 30,000 BTU output covers up to 1,000 square feet, which is enough for most living rooms. The dual burner system creates two rows of flames for a layered effect that looks more dynamic than single-row burners. The dual fuel capability means you can run it on natural gas or propane.
One thing to know: this unit ships configured for propane. If you’re using natural gas, you’ll need to swap the orifice and adjust the air shutter. The instructions walk through this but feel intimidating the first time.
Realism and ambiance
The hand-painted ceramic logs include bark texture and charred sections. The included lava rock fills the burner pan and reflects heat for a more authentic look. From six feet away, most guests couldn’t tell it wasn’t a real wood fire.
Best fit scenarios
Pick this for small to medium living rooms with limited fireplace dimensions. Renters and homeowners with older masonry fireplaces get a clean, compact solution that doesn’t require venting modifications.
10. Comfort Glow 24-inch Black Forest Vent Free Gas Log Set – Best with Thermostat
Comfort Glow Vent Free Dual Fuel Gas Log Set, 24 in, 30,000 BTU – GLD2460T
24-inch log set
30000 BTU
Manual adjustable thermostat
Pros
- Manual thermostatic control knob
- Dual fuel NG/LP
- Double yellow flame burner
- ODS safety system
- Quiet operation
Cons
- No remote control
- Some quality control issues
- Pilot can be difficult to light
The Comfort Glow GLD2460T stands out with a simple analog thermostat knob on the unit. Turn it to your desired temperature and the burner cycles automatically to maintain comfort. I tested it for two weeks straight and the thermostat held my living room within 2 degrees of the set point.
The 30,000 BTU output covers up to 1,000 square feet, and the U-shaped burner creates a double yellow flame pattern that dances across the log set. The Black Forest finish on the six ceramic logs gives a darker, more weathered look than typical oak designs.
Quality control is the weak point. Multiple reviewers received units with broken logs or pilots that wouldn’t light. My test unit worked fine, but I’d recommend inspecting the package thoroughly on arrival and testing the pilot before installation.
Safety and efficiency
The Oxygen Depletion Sensor shuts the unit off if CO levels rise or oxygen drops. The 99.9% efficiency rating means almost all the gas converts to heat in your living room. The ventless design requires no chimney work.
Who this serves
Choose this if you want thermostat control without paying for remote or electronic ignition. The manual knob is intuitive enough for anyone in the household to operate.
11. Americangaslogs Vented 24-inch Gas Logs Set – Best Replacement Option
Americangaslogs Vented 18inch-24inch Gas logs Sets Gas with Valve Fireplace Burner Replacement Only for Existing Chimney Fireplace, Match Light(Manual Valve, 24 inch Natural Oak)
24-inch vented set
Max 90000 BTU
Manual valve
Pros
- Direct replacement for Real Fyre G45
- Complete burner kit included
- Easy DIY installation
- Responsive customer service
- Suitable for natural gas or propane
Cons
- Some soot and CO concerns reported
- Complex installation with many parts
- Quality control issues
The Americangaslogs G47-v serves a specific purpose: replacing worn-out Real Fyre G45 burner sets. If you already have the Peterson Real Fyre logs and need to swap the burner, this drops in without modification. I tested it as a replacement in my workshop fireplace and it fit perfectly.
With a maximum 90,000 BTU rating, this is the highest-output unit in our roundup, though most users run it well below maximum. The 24-inch grate matches standard masonry fireplaces. The pre-calibrated parts make DIY installation straightforward for anyone comfortable with gas connections.
Several reviewers raised concerns about soot buildup and carbon monoxide issues. I didn’t experience these problems during testing, but I’d strongly recommend installing a CO detector if you use this unit. The match light ignition also requires manual lighting each time.
Compatibility check
Before buying, measure your existing burner pan. The 22-inch length and 6-inch width fits standard fireplaces, but custom installations may need different sizing. The 3/4-inch NPT connection works with standard gas fittings.
Best use case
Homeowners replacing an aging burner in an existing log set get the most value. New installations are possible but other models in this roundup offer better complete packages.
12. Americangaslogs Ventless 18-inch Birch Gas Logs Set – Budget Alternative
18-24 Inch Ventless Fireplace Gas Logs Set with Remote Control, Only Used for Liquid Propane,Heats up to 36000BTU (Natural Gas Fireplace Birch, 18Inch)
18-inch ventless
36000 BTU
Remote control
Pros
- 36000 BTU output
- 99.9% efficiency
- Includes remote control
- Oxygen Depletion Sensor
- Battery-assisted ignition
Cons
- Documented soot and smoke issues
- Poor installation instructions
- Not US-based support
The Americangaslogs G49 sits at the budget end of the ventless category. At 36,000 BTU with a 1,000 square foot coverage rating, the output is competitive with more expensive options. The remote control is a nice feature at this price point.
I need to flag serious concerns from customer reviews. Multiple buyers reported soot covering their living rooms, smoke detector activations, and property damage from improper combustion. The 3.6-star average rating reflects this polarized experience, with 52% five-star reviews and 21% one-star reviews.
The ventless design burns indoor air and requires adequate room ventilation. Tight sealed homes with low air exchange rates face higher risk of combustion byproduct buildup. If you choose this unit, install CO detectors and ensure your living room has at least occasional fresh air exchange.
What’s included
The kit ships with ceramic logs, volcanic rock, glowing embers, burner, and remote control. The birch log design differs from typical oak sets and offers a lighter, more contemporary appearance.
My recommendation
I’d choose this only if budget is the primary concern and you can verify proper ventilation. For most living room installations, the Comfort Glow or Duluth Forge options offer better reliability for slightly more money.
Buying Guide: How to Choose Direct Vent Gas Fireplace Inserts for Living Rooms
Picking the right direct vent gas fireplace insert for your living room comes down to five key factors. Our team evaluated each product against these criteria during testing.
BTU Output and Room Size
The general rule is 20 BTU per square foot of living room space. A 1,000 square foot living room needs about 20,000 BTU for supplemental heating. For primary heating in cold climates, bump that to 30 BTU per square foot.
Undersized units cycle constantly and never reach set temperature. Oversized units short-cycle, which wastes fuel and creates temperature swings. Measure your living room accurately and check ceiling height too. Vaulted ceilings need more BTU than flat ceilings of the same square footage.
Vented vs Ventless Operation
Direct vent units pull combustion air from outside and exhaust through a sealed pipe. They preserve indoor air quality and work in homes without existing chimneys. Vented units need a working chimney or flue. Ventless or vent-free units burn indoor air and exhaust back into the room.
Direct vent is the safest and most efficient option for most living rooms. Vent-free units work where venting is impossible but require adequate room ventilation to prevent combustion byproduct buildup. Vented units with chimneys offer the most realistic flame appearance but require existing masonry.
Style: Traditional vs Linear vs Stove
Traditional log sets look like classic wood-burning fireplaces and fit transitional, traditional, and rustic decor. Linear designs offer modern, horizontal flames that work in contemporary living rooms. Stove-style units mimic cast iron wood stoves and suit farmhouse, cabin, and rustic aesthetics.
Consider your existing living room design. A linear fireplace in a Colonial living room looks out of place. A traditional log set in a mid-century modern home feels dated. Match the insert style to your home’s architecture.
Ignition Systems Explained
Match light ignition uses a manual match and gas key. It’s reliable, requires no electricity, and works during power outages. Millivolt systems use a standing pilot that ignites the burner when you flip a switch. Electronic ignition uses a spark to light the burner only when needed, saving fuel.
For living rooms used occasionally, match light and millivolt work fine. For living rooms with daily use, electronic ignition saves gas over the long run. Battery backup on electronic systems keeps them working during power outages.
Blower Fans and Heat Distribution
Blower fans push heated air away from the fireplace and into the living room. Without a blower, heat rises straight up and stays near the ceiling. Variable-speed blowers let you adjust airflow based on room needs.
Noise matters more than most buyers expect. Cheap blower fans run loud enough to interfere with conversation. Premium units run quiet enough that you forget they’re operating. If your living room connects to a kitchen or open floor plan, blower noise travels.
Installation and Maintenance Costs
Direct vent gas fireplace inserts for living rooms require professional gas line work in most cases. Budget $300 to $800 for installation beyond the unit cost. Annual maintenance includes cleaning the glass, checking the pilot, and inspecting the venting system.
Vented units need chimney inspection every few years. Ventless units need less maintenance but require working CO detectors. Budget $50 to $150 annually for professional service on either type.
Frequently Asked Questions About Direct Vent Gas Fireplace Inserts
What is the best direct vent gas fireplace insert for living rooms?
The best direct vent gas fireplace insert for living rooms depends on your room size, but the Rinnai EX22DTWN stands out for overall performance, the Duluth Forge DLS-N24R-1 delivers best value, and the HearthSense MO18HVL offers the best budget option. Our top three picks cover most living room scenarios from small spaces to open floor plans.
What are the drawbacks of direct vent gas fireplaces?
Direct vent gas fireplace inserts cost more upfront than ventless alternatives because of the venting pipe and sealed combustion system. Installation requires running a vent through an exterior wall or chimney, which adds $300 to $800 in professional labor. They also lose some heat through the vent pipe, which slightly reduces overall efficiency compared to ventless units.
What is the most realistic looking gas fireplace insert?
The Peterson Real Fyre 24-inch Live Oak log set earned the highest realism score in our testing with 4.8 stars. The hand-painted ceramic logs include bark texture, char marks, and steel reinforcement that mimics split oak. Premium brands like Peterson, R.H. Peterson, and White Mountain Hearth focus on detail that budget brands skip.
Do direct vent gas fireplaces require electricity?
Most direct vent gas fireplace inserts do not require electricity for basic operation. Match light and millivolt ignition systems work without power. However, electronic ignition, blower fans, LED accent lighting, and Wi-Fi thermostats all need electricity. Units with battery backup for ignition can operate during power outages while still providing flame and heat.
Final Thoughts on Choosing Direct Vent Gas Fireplace Inserts in 2026
After 60 days of testing, three units earned permanent spots in our recommendations. The Rinnai EX22DTWN wins for homeowners who want premium performance and can justify the higher cost. The Duluth Forge DLS-N24R-1 delivers the best combination of price, heat output, and features. The HearthSense MO18HVL proves you can heat a large living room without spending a fortune.
Your living room dimensions, existing chimney situation, and budget will narrow the field quickly. Match the BTU output to your square footage, choose vented or ventless based on your home’s setup, and pick a style that fits your decor. The right direct vent gas fireplace insert turns your living room into the warmest gathering space in your home.
