will be required to clean your Pellet Stove. A high ash fuel may result in daily cleaning, while a low ash content fuel may
result in less frequent cleaning.
will be required to clean your Pellet Stove. A high ash fuel may result in daily cleaning, while a low ash content fuel may
result in less frequent cleaning.
Occasionally, impurities in the fuel will cause a hard mass build up in the burn pot of your Pellet Stove. Impurities, such as
silica, can virtually form little glass balls when subjected to the high heat generated in the burn pot. When allowed to collect,
a hard base build up may block air fl ow through the burn pot, which will signifi cantly affect the performance and effi ciency of
your Pellet Stove. It is a good idea to check the burn pot for any hard mass buildup or other blockage on a daily basis, and
if necessary let the burn pot cool and then clean the burn pot.
