9.3.3 Maintenance of Burner Modules and Combustion Chamber
After disassembly of the boiler, do the procedures as described below.
Maintenance of Burner Modules and Combustion Chamber
1. After removing the burner modules and sealing gaskets from the recesses, use compressed air and
blow the modules from the convex side to the dished side to blow away debris. Inspect for
deformations and damage to the mesh and the module body.
2. Inspect the combustion chamber below the burners for scale and ash. Using compressed air, blow
out the combustion chamber between the sections to remove all dirt and foreign particles from the
aluminum protrusions. Use a water jet to wash the chamber out. Use care to avoid wetting the
electrical wiring.
Inspect the flue duct and flue collector. During this operation, ensure that the condensate drain pipe is
free of blockage so water does not accumulate in the tray. Clean out the condensate tray of any scale
or ash collected from cleaning the combustion chamber.
