What to do if my HearthStone Stove experiences back-puffing or gas explosions?
- B
  Brandon SchneiderAug 2, 2025
  If your HearthStone Stove is experiencing back-puffing or gas explosions, it could be due to a few reasons. One reason might be operating technique, so fully open the primary air control one minute before opening the door and keep it fully open for a few minutes after reloading. Another cause could be an extra low burn rate, in which case you should burn the stove at a higher burn rate. Additionally, a chimney down-draft can cause this issue, and installing a chimney cap may resolve it. Finally, excessive ash build-up can contribute, so empty the ash pan more frequently.

How to increase heat output from my HearthStone Stove?

  Samuel DuranAug 7, 2025
  If your HearthStone Stove isn't producing enough heat, consider these factors: the wood quality (use only air-dried wood, preferably dried at least one year), operating the stove at a low burn rate (operate the stove at a higher burn rate), air insulated chimney (replace with a pre-fabricated insulated chimney system or a properly sized masonry chimney), a cold exterior chimney (reline or insulate the chimney), leaky stovepipe or chimney (check the installation), or too much heat loss from the house (caulk windows, seal openings in home).

Why does my HearthStone Stove have an uncontrolled or short burn?
- K
  Kimberly LewisAug 13, 2025
  An uncontrolled or short burn in your HearthStone Stove can stem from several causes: an unsealed or open door (close the door tightly or replace the gaskets), excessive draft (check the installation and operate at LOW BURN; install stovepipe damper), deteriorated cement seals (reseal the stove with furnace cement), an extra long chimney (shorten the chimney; install stovepipe damper), an oversized chimney (reline the chimney to the proper diameter), high winds or hilltop location (install a chimney cap), or excessive draft (draft in excess of 0.1 wc should be corrected with a stovepipe damper).

  Blistering of the enamel casting on your HearthStone Stove may be caused by operating technique (do not over-fire the stove, monitor stove temperatures, and use seasoned wood only) or excessive draft (check the DRAFT; a damper may be required; operate the stove at a LOW BURN range).

Why does my HearthStone Stove smoke?
- A
  andrewwilkersonOct 26, 2025
  Your HearthStone Stove might be smoking due to several reasons: a cold chimney, which can be solved by preheating the chimney when starting a fire; a blocked chimney, which requires examination of the chimney and stovepipe for blockage or creosote accumulations; an oversized chimney, which can be fixed by relining the chimney to the appropriate diameter; an undersized chimney, which suggests installing a draft inducer or replacing the chimney; a chimney that's too short, which means lengthening the chimney; air infiltration into the chimney, which means sealing chimney connections and openings in clean-out doors; operating technique, which requires to fully open the primary air control one minute before opening doors; or more than one appliance connected to the flue, which means disconnect...
