2.4 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 21 for fan wiring diagram.

3.0 SERVICING AND MAINTENANCE

A. HEATER SERVICING: Frequency of heater servic- ing will depend upon use and type of installation.

B.IMPORTANT: TURN OFF GAS BEFORE SERVIC- ING 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 surrounding the logs clean by vacuuming or brush- ing 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 ASSEMBLY. DO NOT AT- TEMPT 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.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 30.

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 at the pilot generator should be engulfed in the pilot flame (Figure 29).
