Combustion Chamber Cleaning Procedure
17. Protect the electrical components within the boiler
by covering them with a plastic bag or plenty of dry rags. This will eliminate the
possibility of damage to these items from sprayed or dripping water.
18. Using a garden hose with a trigger spray nozzle or similar device,
direct pressurized water in the space between the heat exchanger
tubes. The water should pass freely through the heat exchanger, condensate trap and exit through the condensate drain hose into the pre-
placed bucket.
