BLOWERS AND PRESSURE SWITCH PROBE

DANGER: RISK OF ELECTRIC SHOCK. DISCONNECT POWER BEFORE SERVICING UNIT.

•Blower Cleaning – Over a period of time, ashes or dust may collect on the blades of both the combustion/exhaust blower and convection blower. Periodically, the blowers should be cleaned as the ash and dust can impede performance. The combustion/exhaust blower can be accessed by opening the left, right, and back panels.(Figure 25) To clean the blades in the combustion housing, insert the vacuum tip through the air inlet damper opening located on the side of the combustion housing. Clean thoroughly. To clean the blades in the exhaust housing, use a screw driver to remove the cleaning access panel located on the side of the metal box covering the housing. Insert the vacuum tip through the cleaning outlet and clean the blades thoroughly.

•Pressure switch probe cleaning - Ashes may accumulate on inside tip of the pressure switch probe connector. Use a mesh pad or wire brush to clean the connector and blow inside the tube to make sure it’s free of obstruction.

NOTE: When cleaning, be careful not to bend fan blades. Some stove owners lightly spray an anti-creosote chemical on the fire to help reduce creosote formation within the stove.

Exhaust blower cleaning

a.Creosote Formation – When any wood is burned slowly, it produces tar and other organic vapours, which combine with expelled moisture to form creosote. The creosote vapours condense in the relatively cool chimney flue or a newly started fire or from a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire, which may damage the chimney or even destroy the house. Despite their high efficiency, pellet stoves can accumulate creosote under certain conditions.

b.Fly Ash – This accumulates in the horizontal portion of an exhaust run. Though non-combustible, it may impede the normal exhaust flow. It should therefore be periodically removed.

c.Inspection and Removal – The chimney connector and chimney should be inspected annually or per ton to determine if a creosote or fly ash build- up has occurred. If creosote has accumulated, it should be removed to reduce the risk of a chimney fire. Inspect the system at the stove connection and at the chimney top. Cooler surfaces tend to build creosote deposits quicker, so it is important to check the chimney from the top as well as from the bottom.

The creosote should be removed with a brush specifically designed for the type of chimney in use. A qualified chimney sweep can perform this service. It is also recommended that before each heating season the entire system be professionally inspected, cleaned and, if necessary, repaired.

To clean the chimney, disconnect the vent from the stove.
