Important Safety Requirements for Natural Gas Fireplaces

Installation of natural gas logs must be in a wood-burning vented fireplace that has a working flue constructed of noncombustible materials.
If combustion air is drawn from the home (conventional venting or vent-free products), at least 50 cubic feet of room volume is required for every 1000 BTUs of burner input. This applies to the sum of all equipment burners drawing combustion air from the space.
When a vented natural gas log set is installed, a special damper clip must be affixed to the chimney damper to prevent the damper from closing completely (except for vent-free products).
A fireplace screen or glass door should be installed with all vented natural gas logs and fireplaces (except for vent-free products).
When using an existing chimney for venting, a flue liner may be needed. In addition, you should plan to have your chimney cleaned before installation.
A Carbon Monoxide (CO) alarm is required in homes where a vent-free fireplace product is installed.
Installation of natural gas logs in a prefabricated fire box, that is not UL listed for gas, is prohibited.
