I've recently installed a Breckwell P2700. The combustion air intake is taken from the outisde through a PelletVent Pro exhaust/fresh air combo wall thimble. I did this to avoid the combustion air being sucked in through other sources like the fireplace flu and cooktop vent. It became pretty evident to me that tons of cold air from the outside was making it's way into the stove and out through the convection vent on the front of the stove. Opening up the left side of the stove, the answer was staring me plainly in the face: I'm shocked to discover that the fresh air intake on the back of the unit does not continue through its own pipe to the damper and into the combustion chamber. Note the blue arrow. It shows the intake mixing with the main cavity of the stove. The right side of the arrow is where the air actually enters the combustion chamber, but it's pulling air from all the vents on the back of the stove as well as from outside. What's worse is that the convection blower fan(red arrow) is sucking huge amounts of air from the same chamber and in from the outside. So instead of convection blower air only coming from the inside and combustion air coming from only the outside, their mixing. Has anyone ever complained about smoke from their Breckwell? This seems like an obvious flaw as if the vacuum in this cavity caused by the convection blower is high enough, it could over come the pull of the combustion blower and suck combusted material back and out through the convection vents.
