Maintenance and Service
Explosion, Fire and
Asphyxiation Hazard
Annual Professional Service Required.
Tampering with or making incorrect
adjustments could lead to equipment
malfunction and result in
asphyxiation, explosion or fire.
Do not tamper with the burner or controls or make any
adjustments unless you are a trained and qualified
service technician.
To ensure continued reliable operation, a qualified
service technician must service this burner annually.
More frequent service intervals may be required in dusty
or adverse environments.
Operation and adjustment of the burner requires
technical training and skillful use of combustion test
instruments and other test equipment.
Electrical Shock and
Explosion Hazard
Failure to turn off electric and gas
supply could result in electrical
shock, gas leakage, explosion, or
fire hazards.
Turn main gas valves and electric power off before
performing any maintenance.
If a maintenance procedure requires electrical power,
use extreme caution.
Label all wires prior to
disconnecting when servicing
controls. Wiring errors can cause improper and
dangerous operation.
Verify proper operation after servicing.
Explosion, Fire,
Asphyxiation Hazard
Use authorized replacement parts only. Do not
attempt to replicate or modify any parts.
Annual Maintenance
Explosion, Fire and
Asphyxiation Hazard
Inspect Heating System Regularly. Lack
of regular inspections and inadequate
maintenance could lead to equipment
malfunction and result in asphyxiation,
explosion or fire.
(Always follow the appliance manufacturer’s
recommended service instructions, when available.)
y The following checklist is intended to be used
as a minimum reference guide only and does
not supersede or replace the heating appliance
manufacturer’s recommended service and
maintenance instructions or any code requirements.
y Consult the installation and service instructions
provided by the individual control or component
manufacturer and carefully follow their directions.
y Maintenance and testing may be required more
frequently due to dusty or severe operating
conditions.
y If unusual or questionable performance is observed,
shut the system down and contact your qualified
service agency immediately.
(The following should be performed by a qualified
service technician only.)
○ Inspect and Clean the Burner
1. Inspect and clean all dirt accumulation from the
gas train, burner exterior, burner air band/shutter,
and surrounding area.
2. Remove the blower motor and clean any
accumulated matter from the blower wheel and
motor end bell.
3. Check wheel for damage and the hub setscrew
for tightness. If the blower wheel must be
removed from the motor shaft, insure that
clearance specifications are maintained. See
Figure 16 on Page 25.
4. Clean the inside surfaces of the burner housing
scroll and especially the air intake area and
airflow proving switch suction tube.
5. Clear any debris from the air vents on the motor
body.
6. Clean the ignition transformer, baseplate, and
terminal bushing. Inspect the ignition lead for
signs of deterioration and loose terminals.
7. Remove the gas gun assembly and clean the
entire unit, paying special attention to the air
diffuser and gas orifices. Do not loosen or
disassemble the mounting blocks from the gas
tube. Their settings are important and difficult to
produce under field conditions. See Figure 17
on Page 25.
