In-line duct fan for fresh air intake

[azpaul623]

Has anyone tried putting an inline fan to push more fresh air into the stove? Thought it might help with combustion, anyone have thoughts on this?

Are you talking in-line fan for like a fresh air intake system? I myself wouldn’t unless you have a way to regulate the amount of air it pushes through otherwise it’ll be kinda like running a draft fan non stop and pushing the heat out the exhaust\chimney. If you’re getting cold air from outside and that air is colder than pellet stove location it creates it own draft nicely almost eliminating the need for a draft fan or any forced air altogether. I could be way off but that just my take on it. Good luck!!

By pushing air into the firebox you would be defeating the
safety protocols of the manufacturer.
Changing from a neg draft stove to a pos draft stove
Pushing smoke out of every imperfect seal including the hopper
Possibly even a hopper Fire

Well that would be a giant leap backwards.

The combustion fan does this already and as mentioned above it’s engineered for the stove’s optimum output. Increasing the combustion air would make it burn hotter….possibly burning down the space the pellet stove is heating

You are new, so,welcome, and here is a bit of history. Pellet stoves were "originally" fan forced, instead of "draw through". After many thousands of "smoke in the house", and "house fires", it was realized it was a really bad idea.

If you want to increase the air flow I would go the route of increasing the speed of the combustion fan to draw more air through rather than try and push air through.
