Gas Fireplaces in Bedrooms

We're often asked about installing or renovating fireplaces in bedrooms. Here in Richmond, Virginia it is a controversial issue as building inspectors sometimes do not like the idea due to safety concerns.

Please be assured that we, too, feel that safety is the utmost concerned with any fire. However, we also appreciate a homeowner's desire to install or restore a bedroom fireplace for the warmth, charm and romance a fire offers. A fireplace can be as safe in a bedroom as in any other room of your home.

What About Vent-Free Gas Appliances in Bedrooms?

This issue is particularly misunderstood. Vent-free appliances in bedrooms must be a wall hung heater and must be under 10,000 btu's.

** A vent-free log set that is under 10,000 btu's is not allowed because it is not a wall mounted appliance.

** Vented appliances in bedrooms are NOT limited to the 10,000 btu rule, unless the bedroom is considered a restricted space, as defined below.

The building inspector in your locale has the ultimate approval for fireplace installations. It is helpful to ask which code is applicable in your locality to determine which code he or she is quoting. For example, a direct vent fireplace may be allowed while one with an open fire is not.

The International Fuel Gas Code, for example, states:



303.3 Prohibited locations. Fuel-fired appliances will not be
located in, or obtain combustion air from, any of the following
rooms or spaces:

1. Sleeping rooms.

2. Bathrooms.

3. Toilet rooms.

4. Storage closets.

5. Surgical rooms.


1. Direct-vent appliances that obtain all combustion air directly from
the outdoors.

2. Listed vented gas fired room heaters, listed vented decorative
gas appliances and listed decorative gas-fired appliances for
installation in vented solid fuel burning fireplaces, provided that the
room is not a confined space and the building is not of unusually
tight construction.

The following information is extracted from the Gas Hearth Appliance Training Manual published by the Hearth Products Association:

Appliance Listed:

Equipment or materials tested to required standards by a testing organization ….. Assures suitability for use in a specified manner when equipment installed in accordance with the manufacturer's installation instructons.

Listed VENTED gas appliances will be either:

Room Heater:

Must meet the federal efficiency mandates of the Energy Conservation Act and meet efficiency
standards based on an Annual Fuel Utilization Efficiency (AFUE) based on btu input.

Must have a vent safety shutoff system, designed to stop gas flow to the main burner if the appliace is not connected to a venting system or if the venting system is blocked.

Decorative Appliance:

Is not designed for heating its sole or primary purpose is aesthetic enjoyment

Is not required to meet fuel efficiency standards

Can not use a thermostat to control operation of the flames

Decorative Appliance Installed in Solid Fuel Burning Fireplaces

Standard Z21.60 sets forth requirements for appliances installed into an existing fireplace:

The appliance can only be installed in a non-combustible solid fuel burning fireplace that has a
working flue.

There must be a permanent free opening (usually the damper) of a minimum area determined by appliance input rating and chimney height.

The chimney damper must be fixed in a manner that maintains the minimum permanent vent-free opening.

A fireplace screen must be inplace during operation.

What is a "Confined Space"?

A "confined space" is defined by the National Fuel Gas Code as a space (or room) with less than 50 cubic feet per 1,000 btu input of the appliance.


Can a listed decorative gas coal basket with 25,000 btu input be installed in a 12 'x 15' room with 8 'ceilings?

25 (thousand btu input of the appliance) x 50 (cubic ft required per 1,000 btu input) = 1250 cubic feet.

Length x width x height of room gives the total cubic foot area. 12 'x 15' x 8 '= 1440 cubic feet.

The room area in this example is 1440 cubic feet this appliance needs 1250 cubic feet of area. The appliance could be installed in this room based strictly on the limitations of a restricted space.

Note that the building inspector or other "authority having jurisdiction" in your area should be able to provide you:

Which code is used in your area.

The specifications required and allowed per that code.

The interpretation, if needed, of that code.

Means of implementing that code for your particular installation.

Inspection of your installation to determine that it was performed in accordance with applicable codes and according to manufacturer's installation instructions.

Further Advice. For Installations in Bedrooms or Any Other Room in Your Home:

Heating appliances, decorative gas appliances and their chimneys / venting systems should only be installed and serviced by a qualified technician.

Always follow manufacturer's installation instructions.

Only perform installation in accordance with your local codes.

Apply for a building permit, if required or available, and have the installation inspected by the building inspector.

Notify your homeowners insurance company that a new installation has been performed.

Make sure and have the appliance cleaned and serviced periodically to help assure proper performance.
