INSTALLING HEATER BASE
ASSEMBLY

CAUTION: Do not remove the

data plates attached to the heater

base assembly. The data plates

contain important warranty and

safety information.

WARNING: You must secure

this heater to fireplace floor. If

not, heater will move when you

adjust controls. Moving heater

may cause a gas leak.

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

controls being damaged. Raise

fireplace floor with noncombus-

tible material. Make sure material

is secure.

CAUTION: Do not pick up

heater base assembly by the

burner. This could damage

heater. Only handle base as-

sembly by grates.

IMPORTANT:

Make sure the heater burner is

level. If heater is not level, heater will not work

properly.
