Vent-free gas appliances continue to be the sensible choice when looking for a supplemental heating source. Since no outside

venting is required, all the heat stays in your home and the high heating efficiency provides comfortable warmth for only pen-

nies an hour. And since vent-free appliances do not require electricity to operate, they are an excellent heat source during

power outages. Vent free gas appliances are environmentally clean, safe, and operate within industry indoor air quality stan-

dards as well as being design certified by CSA.

Warning:

•It is recommended that the screen be used during operation of this log

set. Always ensure the screen has adequate spaces to allow for passage

of combustion air to the gas log set.

•Correct installation of the ceramic fiber logs, proper location of the

heater and periodic cleaning are necessary to avoid potential service

problems with sooting.

•Keep small chidren and animals away from the open flame of the gas log

set at all times.

•There may be a start-up odor associated with the heating of the logs.

The odor should diminish in 2-3 hours of operation with the burner at its

highest setting with the fan in the off position.
