OT / Pellet Stove Venting Question

Anonymous-0 · Jul 27, 2008

We have a masonry chimney in the center of our home. It has a 8" thimble in the house with 8" X 12" liners in the interior of the chimney. It is about 25' tall. Can a pellet stove be vented into this masonry chimney with a 3" to 8" adapter located at the thimble and terminated at that point, or will I need to install a venting pipe in the full height of the chimney ? We want to install either the Avalon "Astoria", or the Lopi "Yankee" model pellet stove. We asked the local dealer, but he does not know the answer to this question. I do want a safe installation, BUT I don't want to have spend the money for the liner pipe if it is not needed.

Thank You

I am by no means an expert on this, but a friend of mine is a dealer in Pellet stoves, and I put an older one in this past year. I was told that you have to us ethe vent pipe unfortunetly. Another optio.....put a hole straight out and vent it right outside straight. I did that as well a few years ago. Still working today. Check with your local fire department, they will let you know the codes. Hope I could help you

I guess we will have to get the venting pipe for the chimney then. With the layout of the room, the stove will not be able to be be installed on an outside wall. With the rising cost to heat a home mom is looking into something that may be more cost efficent to operate. I am trying to help my mom and stepdad with this. He had a heart attack 2 weeks ago, and can not do the cutting, splitting, stacking, etc that is involved with burning wood this winter.

Thank You

The price of pellets is not going to get any cheaper.
There are some pellet stoves which can burn biomass pellets or grain. Maybe even coal if you read between the lines. Harmand is one company which comes to mind.
One has to weigh the costs of a new stove, the price of fuel and time to break even. Let alone payback.
It"s possible that just by going around the exiting house with several tubes to chaulking and installing door seals.This may cut the price of home heating to 3/4 of the current costs. With a very modest price input.
Where are you located?

rice coal stoves are pretty good from what i hear as well. The beauty of them is that they can withstand moisture wayyyy better than wood pellets.

That is a interesting question. I would think as long as it is sealed at the three to eight inch pipe it should be ok, and still draw.As soon as it entered the eight inch pipe you could use single wall pipe to the top. This would be a lot less money. I would try another store for information. They will all probably say go the full length to the top for lilability reasons. I put in a wood stove years ago. Everyone told me I needed to go straight up to the top from the stove with no ells. I talked to a old timer, he told me ells were put in all the time years back. That is what I did to keep the pipe from my attic space. That was 30 years ago.Stan

What I have is a 6" metal flue going out thru the ceiling/roof and this was for a wood burning stove. I bought a pellet stove and put the 3" pell vent pipe up thru the metal, it only goes about 12" up into the 6" diam. pipe. I have used the pellet stove for 2 winters like this and the insurance agent guy approved it.

I have been burning a corn stove for 4 years through a brick chimney with clay liner. I just ran the 3inch vent pipe into the side of the chimney and that was it. It has worked great with no problems. I clean out the chimney once a season but see no need for extra expense of a metal liner. pellets are basically wood so you won't have the corrosive problem that burning corn can create.

I hear that, corn doesnt burn that well in a stove. Pellets burn very well and leave only a slight film with dust in the pipe and corn leaves heavy gunk.

I have stainless flex piping that goes from the pellet stove up into the chimney 10 or 12 feet.
Never have any smoke problems. Hal

This is one of those deals where you can try it without the liner pipe, and if draws OK, you're done. If it doesn't, you're not out anything- just put in the liner pipe. If the existing clay liner in the chimney is OK, there's nothing about a pellet stove vs. a regular wood stove that would dictate a liner pipe, except that it's near the end of the month, and the stove salesman's bank account may need a bit of a "refresher".
