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 sooting and con-
trols being damaged. Raise fireplace floor with noncom-
bustible material. Make sure material is secure.
CAUTION: Do not pick up heater base assembly
by the burner. This could damage heater. Only handle
base assembly by grates.
WARNING: You must secure this heater to fire-
place floor. If not, heater will move when you adjust
controls. Moving heater may cause a gas leak.
IMPORTANT:
Make sure the heater burner is level. If heater is not
level, heater will not work properly.
