Heavy snow buildup can definitely affect your pellet stove’s venting and your burn experience. Wood pellet stoves operate through a system of air intake and exhaust. If this system is hindered by a blockage, proper combustion of the pellets can’t happen. Unlike wood stoves, pellet stove venting can be either horizontal, vertical or both.
One of the ways a pellet stove burn exhaust can be set up is horizontally, straight through the exterior wall. (See Fig. A) The exterior vent allows proper air flow within the stove, and the exhaust to escape. If it’s blocked by dense snow – your stove’s ability to ignite and/or stay burning efficiently could be hindered. If your wood pellets aren’t burning through fully – this blockage could be the reason. (See Fig. B)
A similar kind of venting is through the wall with a vertical rise (Fig. C). Vertical piping raises the exhaust further up the exterior wall. This kind of setup holds less risk of snow blockage. However, strong snow drifts (or very high snow accumulation) can still create blockage.
Pellet stoves can also have exhaust vents exiting through the roof – with some variations (Fig. D). If your roof has heavy snow piled up that hasn’t slid off or been pushed off, the vent could be blocked. Make sure to check for blockage – no matter how your stove is vented.
