INSTALLING HEATER BASE ASSEMBLY
WARNING
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 non-combustible material. Make
sure material is secure.
CAUTION
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.
