FAN OPERATION

The accessory fan is wired in series with a speed con-
trol switch and a temperature sensor switch. Set the
speed control to an "ON" position and light the heater.
The temperature sensor switch will automatically start
the fan when the switch warms up—and stop the fan
when it cools down. You can manually stop the fan by
turning the speed control switch to "OFF". See Figure
31 for fan wiring diagram.

SERVICING AND MAINTENANCE

A. HEATER SERVICING: Frequency of heater servic-

ing will depend upon use and type of installation.

B. IMPORTANT: TURN OFF GAS AND ELECTRICAL

POWER BEFORE SERVICING APPLIANCE. IT IS
RECOMMENDED THAT A COMPETENT SERVICE
TECHNICIAN PERFORM SERVICE CHECK-UPS AT
THE BEGINNING OF EACH HEATING SEASON.

C. The appliance and flue system should be inspected

before initial use and at least annually by a qualified
field service person.

D. Inspect the external flue cap on a regular basis to

make sure that no debris is interfering with the air
flow.

E. Keep the control compartment, logs, and burner area

surround the logs clean by vacuuming or brushing at
least twice a year.

CAUTION: THE LOGS GET VERY HOT - HANDLE
ONLY WHEN COOL.

WARNING: DO NOT USE ABRASIVE
CLEANERS ON THE GLASS DOOR AS-

SEMBLY. DO NOT ATTEMPT TO CLEAN THE
GLASS DOOR WHEN IT IS HOT.

F. The glass door should be cleaned using a house-

hold glass cleaner. DO NOT handle or attempt to
clean the glass when it is HOT.

G. Visually inspect the flexible power supply cord; if

damaged, contact the service agent for a special
replacement cord assembly.

H. In order to properly clean the burner and pilot as-

sembly, turn off the gas to the unit and remove the
logs exposing the burner and pilot assembly. Clean
all foreign materials from top of burner. Check to
make sure that the burner orifice is clean.

Visually inspect the pilot periodically. Brush or blow
away any dust or linen accumulations. If the pilot ori-
fice is plugged, disassembly may be required to re-
move any foreign materials from the orifice or tubing.

When the appliance is put back in service check burner
flame patterns with Figure 37.

To obtain proper operation, it is imperative that the pi-
lot and main burner flame characteristics are steady,
not lifting or floating. Typically, the top 3/8-inch (10m)
of the thermocouple should be engulfed in the pilot flame
(Figure 38).

MAKE SURE THE FLAMES
ARE STEADY—NOT
LIFTING OR FLOATING.
