Gas Fireplace Inserts
Direct-vent and vent-free gas fireplace inserts from Majestic and Monessen that convert an existing wood-burning fireplace to efficient gas heat. As an authorized dealer we sell current models at manufacturer pricing with full factory warranty.
Gas Fireplace Inserts: A Practical Buying Guide
A gas fireplace insert is a sealed firebox that slides into an existing masonry or prefabricated fireplace and converts it to gas. Instead of an open chimney pulling heated air out of the room, you get a controlled burner behind glass, thermostat or remote control, and heat that stays inside. It is the usual answer for a wood fireplace nobody uses any more.

What to Check Before You Order
Measure the existing opening first
Insert fit is decided by the width, height and depth of your current firebox, and the usable depth is often less than people expect. Measure all three, plus the front opening height at both sides if the fireplace tapers. Manufacturer framing dimensions are listed on each product page.
Vented or vent free
Direct vent inserts draw combustion air from outside and exhaust through a co-axial liner up the chimney - sealed from your room air, which is why they are the mainstream choice. Vent free models need no liner at all and put all their heat into the room, but are restricted or prohibited in some jurisdictions and in bedrooms. Check your local code before ordering.
Fuel and ignition
Choose natural gas or liquid propane to match your supply - this is set at the model level, not a switch. Electronic ignition systems such as Majestic IntelliFire Touch light on demand and include battery backup, so the fireplace still works in an outage; standing pilot systems burn a small flame continuously.
Fronts, liners and installation
Many premium units are sold as a base appliance, with the decorative front and interior liner ordered separately - that is what lets you match the finish to the room, but it means the listed price is not always the complete package. Read the product page carefully, and budget for professional installation and a gas line: this is not a DIY appliance.
Frequently Asked Questions
- How much does a gas fireplace insert cost?
- The appliance itself typically runs from about $2,800 to $5,300 depending on size, ignition system and finish. Add the decorative front and liner kit where they are sold separately, a flexible vent liner, and professional installation with a gas connection - installed totals commonly land well above the appliance price alone.
- What is a gas fireplace insert?
- A sealed gas firebox designed to be installed inside an existing fireplace opening. It replaces open wood burning with a controlled, glass-fronted gas fire that is far more efficient and can usually be run by remote or thermostat.
- How is a gas insert installed?
- A qualified installer sets the unit in the existing firebox, runs a co-axial vent liner up the chimney for direct vent models, connects the gas supply, then fits the front and liner kit. Permits and a gas-fitting licence are typically required, so this is professional work.
- What is the difference between a gas insert and a built-in gas fireplace?
- An insert retrofits into a fireplace that already exists. A built-in is framed into a wall during construction or renovation, where no fireplace was before. Both can be direct vent; the choice is about what your house already has.
- Do gas fireplace inserts need electricity?
- Electronic ignition models need power for the controls and any blower, but most include battery backup so the fire still lights during an outage. Standing pilot models will light without power, though the blower will not run.
