outside air ?

The exhaust blower is plenty powerful. I have no choice. In retrospect I would have mounted the DV at the same height as the opening of the stove to have a straight pipe instead of a bend.

I got my hole drilled thru the foundation wall. ( used a 3" dry core)
I'm going to use 2" pvc / painted and try to fab as positive a "connection" as possible to the combustion fan. The distribution fan is close to the comb. fan and I'm trying not to suck in additional cold air ?

Work in progress... I'll keep ya posted.

Just make sure your combustion air line isn't anywhere near your DV outlet. U don't want to suck flyash back into the house.

That's the nice thing about my 150 year old house,It breaths all on it's own.I wanted to put in replacement windows but my wife says she likes the old glass with the imperfections.I do go through 7 or 8 tons in a 1500 sq ft house.

Yikes. That is a lot of coal for a 1500 sq. ft. house.

7 or 8 tons for 1500 sf is not a house breathing on it's own, it's a house that's wide open to the great out doors.

That may be why the coal consumpsion is so high for a little house, you may be blowing a lot of heat outdoors from it.

The first year I ran my Alaska I didn't have a rheostat and I only burned 3 tons and my house is about 2k sq. ft. so it's not the DV blower. I would guess they leave the windows open. :shock:

Trader, did you try the exhaust fan experiment?? With either a smoke-stick, or a candle, put it near the outside air vent inlet and then turn on the clothes dryer, bathroom fans, kitchen exhaust fan.. And see how much outside air is drawn in??

If you have a tight house, I suspect you will see a lot of air entering the house via the vent..

I completed my air inlet and must say it looks pretty good.
I used 2" pvc pipe and painted it to match the carpet in the finished area.
Now all I have to do is fire it up and do some adjusting.
Thanks for the tips.

I haven't tried it but I'm sure your right aboiut that. I installed my 3" flex pipe for outside air but I have a paperbag stuck inside of it to keep the bugs out. I have to scrounge up a screen of something and clamp it on.

I just picked up my Pioneer bv stove and am looking for an adapter or flange to hook my 3" outside air pipe to my combustion blower. What are you guys using?

Thanks Matt

Greg suggested to pipe it near it and don't seal it becuase if it gets clogged there could be a problem. I think that's good advice.

The problem with hooking the outside air source directly to the fan inlet and sealing it is that the other end of the vent, the end outside the house could get covered by leaves, a snow drift, a bee's nest, weeds, or even poplar tree seed fluff's.. anything that could clog it would cause a big reduction in air to the stove's fire, and possible CO problems with the stove..

So I recommend just ending the vent behind the stove, near the fan inlet .. or you can get some small angles or 'L's and make three legs that attach the vent to the fan housing, but leave 3/8" or 1/2" gap so it can pull room air in if the outside screen gets clogged..

Safety first..

I have mine piped right to the combustion blower and have never had an issue with anything blocking it. I cover mine outside and remove the flex pipe in the summer. My issue with terminating it right by the blower is a lot of really cold air comes in and not all of it gets taken into the blower it will also be sucked into the convection blower and you would have to heat outside air. Also if for any reason you shut the stove down you would have to block the cold air from coming into the house. The other issue is when you pipe the blower directly to the outside vent it removes a lot of the noise made by the blower. All of the direct vent stoves whether coal or pellet have the blower hooked directly to the outside air supply. I would think that if for some reason it would become clogged the fire would simply die out and you would not have any CO concerns.
