B. Maintenance Tasks-Service Technician
The following tasks must be performed by a qualified technician.
Gasket Seal and Glass Assembly Inspection
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, drop cloth and a stable work surface.
•Inspect gasket seal and its condition.
•Inspect fixed glass assembly for scratches and nicks that can lead to breakage when exposed to heat.
•Confirm there is no damage to glass or glass frame. Replace as necessary.
•Verify that fixed glass assembly is properly retained and attachment components are intact and not damaged. Replace as necessary.
Logs
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves.
•Inspect for damaged or missing logs. Replace as necessary. Refer to Section 12.G for log placement instructions.
•Verify correct log placement and no flame impingement causing sooting. Correct as necessary.
Firebox
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, sandpaper, steel wool, cloths, mineral spirits, primer and
•Inspect for paint condition, warped surfaces, corrosion or perforation. Sand and repaint as necessary.
•Replace appliance if firebox has been perforated.
Control Compartment and Firebox Top
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, vacuum cleaner, dust cloths
•Vacuum and wipe out dust, cobwebs, debris or pet hair. Use caution when cleaning these areas. Screw tips that have penetrated the sheet metal are sharp and should be avoided.
•Remove all foreign objects.
•Verify unobstructed air circulation.
Burner Ignition and Operation
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, vacuum cleaner, whisk broom, flashlight, voltmeter, indexed drill bit set, and a manometer.
•Verify burner is properly secured and aligned with pilot or igniter.
•Clean off burner top, inspect for plugged ports, corrosion or deterioration. Replace burner if necessary.
•Replace Glowing embers with new
•Verify batteries have been removed from battery back- up IPI systems to prevent premature battery failure or leaking. For optimal battery life, locate the battery pack outside of the control cavity on the hearth. This place- ment will reduce the chances of overheating the batteries during extended burns which could result in reduced battery life or degradation.
•Check for smooth lighting and ignition carryover to all ports. Verify that there is no ignition delay.
•Inspect for lifting or other flame problems.
•Verify air shutter setting is correct. See Section 12.I for required air shutter setting. Verify air shutter is clear of dust and debris.
•Inspect orifice for soot, dirt and corrosion. Verify orifice size is correct. See Service Parts List for proper orifice sizing.
•Verify manifold and inlet pressures. Adjust regulator as required.
•Inspect pilot flame pattern and strength. See Figure 3.1 for proper pilot flame pattern. Clean or replace orifice spud as necessary.
•Inspect IPI flame sensing rod for soot, corrosion and deterioration. Polish with fine steel wool or replace as required.
•Verify that there is not a short in flame sense circuit by checking continuity between pilot hood and flame sense rod. Replace pilot as necessary.
