Hello folks,

This morning the carbon monoxide detector went off in the furnace room. We called the company who serves our furnace. The guy inspected it and found nothing wrong.
When he moved the detector closer to our wood stove, it was triggered instantly. The CO level was around 60.
We ran the stove last night, and it was still warm inside when the furnace guy checked it.

The wood stove was installed in last May, and CO seeping into the house happened for the first time today.

How can we prevent this problem in the future?
Will fresh air intake pipe help?

thank you!
 
Some stoves are fed 100% of their intake air through the outside air connection. Some have several air intakes and only connect one to outside air. If yours is the first kind then I think the outside air will help.

Reversing a flue is not easy but a dryer, range hood, or even a bathroom fan can cause at least a portion of the smoke to be pulled out of the stove through the intake.

Connecting all intakes to an outside air pipe prevents all of those other fans from being able to suck the smoke out of your stove.

And then, some houses make better chimneys than the chimney. Upstairs air leaks create a draft through the house kind of like a large warm chimney.

Thank you! I didn’t realize that dryer and fan can have so big impact on the stove.
