Pellet Stove creating excessive soot in house

We have and America's Harvest Pellet stove and this is our 2nd year. I don't recall the soot in the house being as bad last year as it is this year. We are currently buring cherry pits and we use the stove 24 hours a day. The problem is, my entire house (2800 sq. feet) is full of fine black soot.

Comments (10)

I think you need to call either the stove store or your installer: that soot indicates to me [a non-pro] that your vent system is leaking into the house.

Regular Cleaning

Waiting until it's time for seasonal maintenance, at the beginning or end of winter, means that soot, creosote and ashes have had a chance to build up on the glass. Built-up soil is much harder to remove and can lead to stains. Pellet Stove Pro recommends cleaning the glass every few days to prevent build-up.

Cleaning Methods

Commercial wood or pellet stove glass cleaner is designed to remove soil without scrubbing and is used the same way as standard glass cleaner.

Type of Pellets

Low-quality pellets don't burn as cleanly as high-quality ones, leaving behind a bigger mess. Binders or glue in the pellets can leave behind a residue on the glass that is difficult to clean. Also, the additional smoke and soot produced by cheaply made pellets can coat the glass in a matter of hours, undoing all of the work to get it clean.

Airflow

Poor airflow can cause even the best pellets to create a lot of smoke and soot. Keep the exhaust flue clean and adjust the damper so that the pellets are burning as cleanly as possible with a steady yellow flame.
