Vent-Free Gas Fireplace

A vent-free gas fireplace (also called a ventless gas fireplace) burns natural gas or propane without a chimney or vent pipe, so nearly all of its heat stays in the room and it can go where a vented unit cannot. Vent-free units carry an oxygen depletion sensor (ODS) that shuts off the gas if oxygen in the room drops, and they are sized by BTU input to the room they heat.

Vent-Free Gas Fireplaces and Fireboxes from Empire, Superior, Buck Stove, Kingsman and More

This page covers complete vent-free fireplaces and zero-clearance vent-free fireboxes from Empire Comfort Systems, Superior Fireplaces, Buck Stove, Kingsman, Napoleon, Monessen and Majestic, from 24" to 55" wide, in natural gas and propane versions. It also includes a few Superior outdoor vent-free models.

Four things to settle before choosing:

  • Local code. Vent-free gas appliances are restricted or not permitted in some states and municipalities, and many codes limit their use in bedrooms and bathrooms. Confirm with your local building department before you order.
  • Room size and BTUs. Codes cap a vent-free unit's BTU input based on the volume of the room. Match the rating to your space; several Empire models are offered in a lower 10,000 BTU version for smaller rooms.
  • Firebox or complete fireplace. Many items here are fireboxes only, and the vent-free log set or burner is ordered separately. Check the product title and page for the parts needed to complete the unit.
  • Supplemental heat. Combustion byproducts and water vapor stay in the room, so vent-free fireplaces are designed for supplemental heat. Follow the manufacturer's operating instructions.

Send us your room dimensions and fuel type and we will help you size the right model: 917-540-6070, Mon–Fri 9AM–6PM EST.
