Burner:

Run the burner and perform a complete combustion 
test using the proper instruments before 
proceeding. If necessary refer to the section labeled 
Start the Burner. Record the results for reference.
Inspect and clean all dirt accumulation from the 
gas train, burner exterior, burner air damper, and 
surrounding area.
Remove the blower motor and clean any 
accumulated matter from the blower wheel and 
motor end bell. 
Clean all fl ue passages and fl ue pipe. Replace 
corroded or damaged pipes. 
Check wheel for damage and the hub setscrew for 
tightness. If the blower wheel must be removed 
from the motor shaft, insure that clearance

specifi cations are maintained (blower wheel hub to 
motor clearance should be .020”).
Clean the inside surfaces of the burner housing 
scroll and especially the air intake area and airfl ow 
proving switch suction tube. 
If the blower motor does not have permanently 
lubricated bearings, oil the motor. Clear any debris 
from the air vents on the motor body.
Clean the ignition transformer, baseplate, and 
terminal bushings.  Inspect the ignition leads for 
signs of deterioration and loose terminals. 
If the burner fl ame detection is a UV scanner, 
inspect the mounting and clean the lens 
according to the component manufacturer’s 
recommendations.
Remove the gas gun assembly and clean the entire 
unit, paying special attention to the air diffuser and 
spuds.
Inspect the fl ame rod (if used) for oxidation or 
distortion. Clean all surfaces, set the probe position, 
and insure that the fl ame rod is securely fastened. 
Refer to Figures 15A, and 15B.
Inspect the ignition electrode for any damage. 
Clean all surfaces, set the proper electrode gap, 
and make sure it is securely fastened.
Clean the inside of the air tube and inspect the 
combustion end for any deterioration. Referring 
to Figure 2, check the recess dimension from 
refractory.
Inspect gas tube O-ring condition and replace if 
damaged.  Install gas gun assembly back into the 
burner and use the jacking screw to tighten the 
gas gun securely in place. (Automotive chassis or 
bearing grease is suitable for o-ring lubrication.)
Inspect the condition of the appliance mounting 
plate and burner mounting fl ange gaskets and 
replace any damaged materials. See Figure 6.
Inspect all burner control wiring and the burner 
control panel for damaged insulation and loose 
terminals/connections.
Verify that the source voltage to the burner and 
control panel is within 10% of the burner rating as 
listed on the nameplate. (Figure 1)

Check the condition of the combustion chamber 
refractory, the front-plate insulation, and all gaskets 
and seals. Repair or replace as necessary
Insure that the fl ue passages, fl ue vent pipes, and 
chimney fl ues are clean and unobstructed.

Do not tamper with the burner or controls or make 
any adjustments unless you are a trained and 
qualifi ed service technician.
To ensure continued reliable operation, a qualifi ed 
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.
