3.0 SERVICING AND MAINTENANCE
1. HEATER SERVICING: Frequency of heater servic- ing will depend upon use and type of installation.
2.IMPORTANT: TURN OFF GAS BEFORE SERVIC- ING APPLIANCE. IT IS RECOMMENDED THAT A COMPETENT SERVICE TECHNICIAN PERFORM SERVICE
3.The appliance and flue system should be inspected before initial use and at least annually by a qualified field service person.
4.Inspect the external flue cap on a regular basis to make sure that no debris is interfering with the air flow.
5.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 ATTEMPT TO CLEAN THE GLASS DOOR WHEN IT IS HOT.
6.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.
7.Visually inspect the flexible power supply cord; if damaged, contact the service agent for a special replacement cord assembly.
8.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. Flames should be steady, not floating.
To obtain proper operation, it is imperative that the pilot and main burner flame characteristics are steady, not lifting or floating. Typically, the top 3/8 inch of the ther-
mocouple should be engulfed in the pilot flame (See Figure 3.1).
