INSTALLING HEATER BASE ASSEMBLY

You must secure this heater to fireplace floor. If not, heater will move
when you adjust controls. Moving heater may cause a gas leak.
If installing in a sunken fireplace, special care is needed. You
must raise the fireplace floor to allow access to heater control
panel. This will insure adequate air flow and guard against soot-
ing. Raise fireplace floor with noncombustible material. Make sure
material is secure.
Do not pick up heater base assembly by burners. This could
damage heater. Only handle base assembly by grates.
IMPORTANT: Make sure the heater burners are level. If heater is not level, heater
will not work properly. For thermostat models, avoid damage to thermostat bulb.
Avoid nicks or sharp bends in thermostat bulb wire. Keep thermostat bulb in
mounting bracket.
