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 non-combustible material. Make
sure material is secure.
Do not pick up heater base assembly by the burner. This could
damage heater. Only handle base assembly by grates.
IMPORTANT: Make sure the heater burner is level. If heater is not level, heater
will not work properly.
