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 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 touch-up paint.
• 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 dime-size pieces.
DO NOT
block ports or obstruct lighting paths. Refer to
Section 12 for proper ember placement.
•
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
placement 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 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 thermocouple/thermopile or 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.
