WARNING: A qualified ser-

place to gas supply. Follow all
local codes.
If any of the original wire as supplied with
the appliance must be replaced, it must be
replaced with 105˚C wire or it's equivalent.
Operating the Blower
After final installation of your fireplace,
light your gas appliance with the blower off.
After about 15 minutes, turn the blower on
to deliver heated air at the top louvers. The
blower features a variable control which
allows you to select the speed you desire. In
the OFF position, the blower will not oper-
ate. In the ON position, the blower will start
when the thermostat senses a sufficient in-
crease in firebox temperature (approximately
10 to 20 minutes depending on heat setting).
Your gas logs and thermostat blower will
not turn on and off at the same time. The
fireplace may run for several minutes before
the blower turns on. After the heater modu-
lates to the pilot position, the blower will
continue to run. The blower will shut off
after the firebox temperature decreases.
It is safe to operate fireplace with blower
turned off. However, the blower helps dis-
tribute heated air from the fireplace.
Note:
Periodically check the louvers of the
firebox and remove any dust, dirt, or other
obstructions.
15. If gas connections have been made and
checked, replace fireplace floor assem-
bly in fireplace. Feed flexible gas sup-
ply line into fireplace base area while
replacing fireplace floor assembly. Make
sure the entire flexible gas line is in fire-
place base area.
IMPORTANT:
Do not
pick up fireplace floor assembly by
burners. This could damage burners.
Only handle base by grates.
Note:
Be
careful of all wires and components on
underside of floor assembly.
16. Reattach fireplace floor assembly with
screws removed in step 3 of Removing
Fireplace Screen and Floor Assembly,
page 8.
Note:
Discard the remaining
hardware items. After assembly, make
sure all wires are completely clear of
blower wheel.
17. Install logs (see Installing Logs, pages
19 and 20) and fireplace screen (see In-
stalling Fireplace Screen, page 20).
