Combustion Blower Cleaning

Remove the combustion blower heat shield. There are two latches that hold the shield in place (See Fig. 22). Flip the latches up and pull the shield away from the boiler. It can not be fully removed, it can only be moved down over the wire until it hangs on the junction box.

The boiler MUST be OFF and COOL before you should attempt to clean the combustion blower.

The wire to the combustion blower doesn’t need to be disconnected during the cleaning process.

Loosen the three (3) thumb screws about 4 turns each. See Fig. 23. Hold the motor head with one hand and the blower plate handle with the other hand. Pull outward on the plate handle until the complete unit comes loose. Now rotate the plate counter-clockwise about 1/8 turn. This will allow the complete assembly to be removed from the blower chamber.

Clean the blower fan blades and the blower plate sealing overlap. See Fig. 24.

NOTE: Be careful not to bend the fan blades, this will throw the fan blade out of balance or it may rub the inner chamber, which may affect the performance of the boiler. Any horizontal and vertical flue pipe directly above the unit should be cleaned at this time

NOTE: The horizontal flue pipe directly above the boiler is the first place fly ash will settle, due to the slowing of flue gas velocity through horizontal pipe. Cleaning of horizon- tal venting pipes is very important to the efficiency of this boiler.

Clean the flue outlet throat as well as the inner chamber of the flue tunnel (this is the hole that goes up into the flue pipe). See Fig. 24.

NOTE: The exhaust probe sensing tip extends into this same area. CARE MUST BE TAKEN NOT TO DAMAGE THE ESP DURING CLEANING. Bending of the ESP will make it difficult to remove if it should become necessary. See Fig. 23.

Clean the boiler blower plate, sealing overlap. See Fig

24.Make sure there are no fly ash buildups that may block the easy flow of flue gasses into the combustion blower inlet hole. ( A flashlight may be necessary. )

Cleaning the Tube Heat Exchangers:

The heat exchanger tubes have external handles that operate the cleaning mechanisms. See picture on page 32.

This cleaning should be done at least once a week, although it can be done as often as desired. The cleaner the heat exchangers are, the more efficient the boiler will be. This cleaning can be done at any time and in any mode of operation. During high fire periods, the cleaning rods may stick due to heat related expansion.

CAUTION: Inspect flue pipes, flue pipe joints and flue pipe seals regularly to ensure that smoke and flue gases are not entering the home.
