Burner Assembly Cleaning
1.
After disconnecting power to the boiler,
remove the boiler’s furnace door. For
part identification, refer to the “Repair
Parts” section of this manual.
2.
Clean around the burner assembly by
blowing compressed air over the surface
of the burner to remove lint and debris
accumulation. Be careful when cleaning
the burner assembly, to avoid damaging
the metal mesh burner surface.
3.
If the burner or the burner gasket shows
any visual deterioration or corrosion
signs, replace it immediately.
4.
After replacing the burner or burner
gaskets, check for proper operation by
performing combustion analysis, as well
as checking for gas leakage around the
burner mounting and blower transition
pieces.

Heat Exchanger Cleaning
1.
Perform visual inspection of both boiler
flue passes, and remove any debris from
the surfaces of the heat exchanger.
2.
If necessary, brush the tubes of the heat
exchanger using non-abrasive, non-
metallic bristle brush.
3.
Be careful not to damage or disturb the
insulation inside of the heat exchanger.
