Ash removal is made easier with the WoodMaster Plus' user-friendly design that cleans out with ease. It is important to clean out your flue tubes on a weekly basis, keeping the furnace heat transfer area working efficiently. The ash pan will be emptied as need, every 4 days depending on heat load. The AFS 900 fire box should be cleaned every two weeks.
At the end of the heating season, it is very important to clean out all ash from the heat transfer area and also the fire box. Cover the chimney to not allow moisture to enter into these areas. Moisture mixed with ash can create damage to the furnace.
