INSTALLING HEATER BASE ASSEMBLY

controls. Moving heater may cause a gas leak or log
misplacement.
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
ensure adequate air flow and guard against sooting
and controls being damaged. Raise fireplace floor
with noncombustible material. Make sure material
is secure.

base assembly by grates.
