Burner Ignition and Operation
Frequency: Annually
By: Service Technician
Tools needed: Protective gloves, vacuum cleaner, whisk
broom, fl ashlight, 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 fl ame 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 orifi ce for soot, dirt and corrosion. Verify orifi ce
size is correct. See Service Parts List for proper orifi ce
sizing.
• Verify manifold and inlet pressures. Adjust regulator as
required.
• Inspect pilot fl ame pattern and strength. See Figure 3.1
and 3.2 for proper pilot fl ame pattern. Clean or replace
orifi ce spud as necessary.
• Inspect thermocouple/thermopile or IPI fl ame sensing rod
for soot, corrosion and deterioration. Clean with emery
cloth or replace as required.
• Verify thermocouple/thermopile millivolt output. Replace
pilot as necessary. (Standing pilot only)
• Verify that there is not a short in fl ame sense circuit by
checking continuity between pilot hood and fl ame sense
rod. Replace pilot as necessary. (IPI only)
