Ensure belt tensioner is in place and tensioner roller is running smoothly.
Clean inside of combustion chamber with a wire brush. Vacuum all ash
and soot from combustion chamber.
Inspect combustion chamber for any damage. Do not use a heater that
has a hole in the combustion chamber.
Remove burner from burner assembly
Clean flame rod and igniter with solvent or emery cloth. Inspect for
cracked ceramic. Ensure they are properly centered in the burner
openings. Inspect wires for cracks or evidence of overheating
Ensure burner head screws are tight.
Ensure openings in orifice plate (located inside the burner pipe) are not
blocked. Ensure gasket and door seal are in place and not damaged.
Replace if necessary.
Ensure ground wires are properly connected.

Wipe dirt from motors. Motors have sealed bearings and do not require
lubrication.
If heater has not been used in more than a year, connect power, turn
power switch to the appropriate power source and let the heater sit for
one hour for each year since the heater was last used. This will reform
the capacitors and extend the life of the VFD.
Verify that manifold pressure matches the specification label. Adjust
regulator pressure if necessary.
Inspect strainer and clean if necessary.
Using soapy water or gas leak detector, check all gas connections for
leaks.
Remove any dirt build-up on both burner and blower impellers.
Inspect impellers for loose or damaged fins.
Run heater and check for vibration.
Replace impellers that are damaged or causing vibration.
Ensure all panels and shields are in place and that fasteners are tight.
