Cleaning the Burner Modules
– Continued
1. Carefully lift each burner module from its position. Remove both the module and the
gasket. Discard the used gasket, as each one will be replaced at reassembly.
WARNING!
The burner gaskets
MUST
be replaced at every cleaning.

2. Use only compressed air to clean the burners by blowing into the “side flame” side of the
burner mesh. See Figure 7-24.

3. Visually inspect burner mesh and the spot welds at the L profile (where the mesh is welded
to the frame) for integrity. If welds are compromised or the burner mesh is damaged, the
burner module should be replaced.
4. Once all the burner modules are removed, wash the combustion chamber underneath with
water. Avoid getting the electrical harnesses and components wet.
5. During this operation, inspect to the condensate drain pipe to determine if it is free of
obstructions; wash water should drain freely from the condensate drain pipe.
6. Blow the combustion chamber with compressed air and attempt to remove any dirt clogging
the aluminum pins of the combustion chamber wall. If any buildup is found on the heat
exchanger, particularly on the lower heat exchanger pins, remove it with a stiff plastic
brush.
7. Once the washing of the aluminum sections is finished, make sure the condensate drain
and trap are free of obstructions. Clean them if necessary.
8. Inspect the flue exhaust section, including the exhaust piping.
