How much does it cost to install a direct vent gas fireplace?

Installing a direct vent gas fireplace can range in cost from $2,000 to $5,000 on average. The final cost will depend on the size and model of the fireplace unit, the difficulty of the installation, and any customization options selected.

What is a direct vent gas fireplace?

A direct vent gas fireplace is a sealed combustion system that vents completely to the outside. It draws in fresh air for combustion from the outside and expels the exhaust gases directly out through a dedicated vent. This makes the fireplace extremely efficient and safe to use since the combustion gases are not entering the home.

Factors that affect the cost of installation

There are several main factors that can impact the total installation cost of a direct vent gas fireplace:

• Fireplace size – Larger fireplace units will cost more. Standard sizes range from 30″ to 60″ wide.
• Venting configuration – Vertical or horizontal venting will impact labor time and vent materials needed.
• Gas line connection – If there is no existing gas line near the install location, running a new gas line can add $500-$1,000.
• Electrical and framing work – Any needed electrical, drywall repairs or framing will add cost.
• Difficulty of installation – If extensive modifications are needed for the install, this can drive up cost in labor and materials.
• Added accessories – Things like blowers, lights, special media sets or fireplace surrounds will add to the bottom line.
• Location – Prices are often higher in places like NYC or LA where labor rates are higher.

Cost breakdown

Here is a typical cost breakdown for installing a direct vent gas fireplace:

Expense	Average Cost
Fireplace unit	$1,500 – $3,500
Venting materials	$300 – $1,000
Gas line connection	$200 – $500
Labor	$500 – $1,500
Total average cost	$2,500 – $5,000

Fireplace unit cost

The fireplace unit itself will be the biggest cost. Expect to pay $1,500-$3,500 depending on size, fuel type, and features. Basic 30″ to 40″ direct vent gas fireplaces start around $1,500. Larger see-through and premium designer units can cost $3,500 and up.

Venting costs

Direct venting must be routed from the fireplace outdoors. This requires stainless steel vent piping and an exterior vent termination kit. Venting costs $300-$1,000 depending on the length of venting required, number of elbows, and vent termination style.

Gas line cost

If there is already a gas line near the desired fireplace location, connecting the unit may only cost around $200 in parts and labor. If there is no gas line that can be accessed, running a new gas line under the floor or in the wall will cost an additional $500-$1,000, or more if extensive piping is required.

Labor cost

In most cases, a professional gas fireplace installation will take 2 full days at $500 per day, for $1,000 in labor costs. Simple installs can sometimes be completed in 1 day at around $500 labor. Complex jobs requiring venting through multiple floors or exterior walls can run up to 3 days at $1,500 labor.

Cost to install a gas fireplace insert

A gas fireplace insert is installed inside an existing wood burning fireplace. This allows you to convert from wood to gas within your current masonry or pre-fab wood burning fireplace. Installation costs for a gas insert are typically lower since the existing chimney can often be used for venting.

Here are typical costs for installing a gas fireplace insert:

• Gas fireplace insert unit – $1,200 – $2,500
• Venting – $0 if using existing chimney, up to $500 if chimney relining is required
• Gas line – $200 on average if gas line is accessible
• Labor – $500 – $1,000
• Total average cost – $1,900 – $3,500

Adding a blower or fan

Many direct vent gas fireplaces allow for the addition of a blower or fan. This improves heat circulation into the living space. A fireplace blower will typically cost $200-$500 including labor for wiring and installation.

Cost to convert wood fireplace to gas

If you have a wood burning fireplace, a full conversion to a gas fireplace will cost around $4,500 on average. This includes:

• Gas fireplace insert unit – $2,000
• Gas line installation – $500
• Venting – $500
• Labor for install – $1,000
• Misc supplies, permit fees, etc – $500

This assumes your existing woodburning fireplace and chimney are in good shape. Repairs for run down chimneys or surrounding brickwork will add cost. A gas log set can also be installed in a wood burning fireplace as a simpler alternative starting around $1,500.

Adding a fireplace ignition system

Modern direct vent gas fireplaces often come with advanced control panels or ignition systems that allow you to turn the fireplace on/off with a switch or even remotely with a smartphone app. Retrofitting an electronic ignition can cost $100-$300 in materials, around $200 for labor, for a total of $300-$500 installed.

Types of electronic ignition systems for gas fireplaces:

• Basic on/off wall switch – $100
• Battery operated push button igniter – $150
• Advanced programmable touchscreen wall panel – $500
• Smart home app integration – $300

Can you install a gas fireplace yourself?

It is possible for a very skilled DIYer to self-install a direct vent gas fireplace. However, extreme care must be taken when dealing with gas lines, venting, and electricity. Any mistakes can lead to dangerous fire hazards or gas leaks that can be fatal.

It is highly advisable to hire a professional gas fireplace installation company. They have the extensive experience, proper tools, and certifications needed to safely install these complex units. DIY mistakes could lead to carbon monoxide poisoning or fires.

Hiring a professional

When hiring a company to install your direct vent gas fireplace, find a licensed contractor that specializes in fireplace installation. Expect to pay around $65-$100 per hour in labor costs in most areas.

Be sure to get at least 3 detailed quotes and verify the company’s licensing and insurance. You can also check for reviews online. Good communication is key to ensure the unit is properly sized and located based on your home. They should also handle securing any needed permits.

Conclusion

Installing a direct vent gas fireplace costs between $2,000 and $5,000 on average. This includes the fireplace unit, venting, gas line, labor, and any special accessories selected. Exact costs vary based on size, difficulty, and local rates. Luxury designer fireplaces with custom finishes can cost up to $10,000 fully installed. While a complex project, a gas fireplace offers a beautiful and efficient way to add heat and style to your living space.
