Asphyxiation Hazard
Inspect Heating System Regularly. Lack
of regular inspections and inadequate
maintenance could lead to equipment
malfunction.
(Always follow the appliance manufacturer's
recommended service instructions, when available.)
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.
Consult the installation and service instructions
•
provided by the individual control or component
manufacturer and carefully follow their directions.
Maintenance and testing may be required
•
more frequently due to dusty or severe
operating conditions.
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.
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.

8. Inspect the flame rod for oxidation or distortion.
Clean all surfaces, set the probe position, and
insure that the flame rod is securely fastened.
Refer to Figure 22 on page 31.
9. Inspect the ignition electrode for any damage.
Clean all surfaces, set the proper electrode gap,
and make sure it is securely fastened. See
Figure 22 .
10. Clean the inside of the air tube and inspect the
combustion end for any deterioration. Check the
recess dimension from refractory.
11. Inspect gas tube O-ring condition and replace if
damaged. Install gas gun assembly back into the
burner and tighten the gas gun securely in place.
(Automotive chassis or bearing grease is suitable
for O-ring lubrication.)
12. Inspect the condition of the appliance mounting
plate and burner mounting flange gaskets and
replace any damaged materials.
13. Inspect all burner control wiring and the burner
control for damaged insulation and loose
terminals/connections.
14. Verify that the source voltage to the burner and
control panel is within 10% of the burner rating as

procedures. The following steps are emphasized
because they relate to burner operation)
1. Insure that the flue passages, flue vent pipes,
and chimney flues are clean and unobstructed.
2. Check barometric damper or draft hood for
proper operation.
3. Check the condition of the combustion
chamber refractory, the front-plate insulation,
and all gaskets and seals. Repair or replace
as necessary.
4. Inspect boiler sections and system load piping
for possible leaks. Make all necessary repairs.
5. Check all operating and safety controls on the
boiler for proper installation and operation.
6. Perform all maintenance and tests according to
the burner control manufacturer's instructions
(limits, controllers, low water cutoff, relief valves,
feed valves, etc.).
