push in or turn by hand, do not try to repair it, call a
qualified service technician. Applying force or any
attempted repair may result in a fire or explosion.

D. Do not use this fireplace if any part has been under

water.  Immediately call a qualified service techni-
cian to inspect the heater and to replace any part of

Immediately call your gas supplier from a
neighbor's phone.  Follow the gas supplier's
