The fi replace and gas logs function as a
system. If the fi replace is spilling into the
room (check with a match or a smoke stick),
reposition the damper clamp until a positive
draft is obtained by opening the damper. If
negative pressure in home prevents having
a positive draft, contact your dealer for
assistance.

PLACE AND SECURE APPLIANCE

You must secure the gas log heater to
the fi replace fl oor. If not, the entire unit
may move when you adjust the controls.
Movement of unit may cause shifting of
the gas logs which leads to sooting and
improper burning.
Special care is required if you are installing
the unit into a sunken fi replace. You must
raise the fi replace fl oor to allow access to
gas log controls. This will insure adequate
air fl ow and guard against sooting. Raise
the fi replace fl oor using noncombustible
