Gas Fireplace Inserts

Direct vent or vent-free

A direct vent gas fireplace insert uses sealed pipe up your chimney for outside air and exhaust. The fire sits behind a glass front. Plan for a chimney liner. A ventless fireplace insert needs neither pipe nor liner; nearly all heat stays indoors. A sensor monitors room air. Check local code for restrictions. For a new wall, browse whole direct vent fireplaces or ventless fireplaces and fireboxes.

Choose a gas fireplace insert

Measure width, height and depth, front and back. Every insert here can be ordered as a natural gas fireplace insert or a propane fireplace insert, with your fuel choice picked on the page.

Empire Comfort Systems offers three direct vent lines, including tall flames around logs and raised burners with ember glass. Its two vent-free lines offer logs or crushed glass. Majestic offers 25 to 35 inch direct vent inserts with lights beneath the logs and battery backup. Superior fits masonry or factory built fireplaces in 27- or 32-inch sizes. Monessen offers a 33-inch vent-free unit with a fan and brick-look or black panels. Napoleon offers Rosedale and Oakville direct vent inserts for your existing masonry or factory built wood burning fireplace.

Compare standing pilot and electronic ignition options. If you want a gas fireplace insert with blower, several units include this fan to push warm air into the room, and it needs household power.

Other ways to go

Choose wood burning inserts for masonry, electric inserts for no gas line or chimney work, or gas logs for looks rather than heat.

Frequently asked questions

Can you put a gas fireplace insert in an existing fireplace?

Yes. Most fit a masonry fireplace; Superior and Napoleon also fit a factory built one. A surround covers the opening, and a gas line must reach the firebox. Measure width, height and depth, then select the size on the page.

What is the difference between a direct vent and a ventless gas insert?

Most here are direct vent: sealed chimney pipe supplies outside air and removes exhaust. A few are vent-free: no pipe or liner, nearly all heat stays inside, and a sensor monitors room air. Some areas restrict vent-free units.

Is a gas insert better than a gas log set?

For heat, yes. A log set makes an open fire, with most warmth going up the chimney. An insert heats the room, often with a fan. Choose a log set when the look of the fire matters more than warmth.

Will a gas fireplace insert work in a power outage?

Units with a standing pilot or battery backup can light and burn without household power. Choose the standing pilot option if outages matter to you. The blower stops without power, but the fire and its radiant heat carry on.
