MAINTENANCE AND SERVICING
Maintenance Checklist:
The following should only be performed by a qualified service technician.
CAUTION: Label all wires prior to disconnection when servic- ing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
1.Annual inspection should be made and the following checks performed:
oWhen unit is cool, open glass viewing door and inspect burner for dirt, soot and lint accumulations and remove if necessary. If exces- sive soot accumulation is present on burner, have a qualified service technician adjust burner for proper combustion.
oClean inside of glass viewing door with gas fireplace glass cleaner. NEVER attempt to open door or clean glass when unit is hot.
oCheck the hot air outlet vents for lint or other accumulations. Never block or restrict vent openings or obstruct flow of ventilation air.
oCheck that direct vent pipe, air intake and flue are open and free of soot, blockage, or debris.
oCheck gaskets once a year. Gaskets must be tight. Replace if neces- sary.
oInspect the pilot system for proper flame. NEVER ADJUST THE PILOT until after the gas pressure has been checked and supply lines have been completely bled (this may take an hour or more when bleeding through the pilot). All pilots are checked and burned at the factory prior to shipment. The pilot adjustment screw is located to the lower left of the flame height control knob.
.25 Adjust the pilot screw to properly size the flames. The flames should completely surround the thermopile and thermocouple and extend across the main burner tube ports. Be careful not to back the screw out of its threads.
oCheck that the area around the stove is kept clear and is free of combustible materials, gasoline and other flammable vapors and liquids.
oCheck the millivolt system as per the table on this page.
2.The viewing glass should be cleaned periodically (see Glass Door Cleaning and Maintenance).
3.Should repairs or maintenance of the stove require the disassem- bly of the vent/air intake system, the reassembly and resealing should be completed by a qualified service technician and follow the instructions on Page 10 of this manual.
