CERTIFIED WOOD STOVE THAT USES A 5" FLUE PIPE

Does anyone make a wood stove that uses a 5" flue pipe?. I would need it to be available in Ontario Canada. I noticed a lot of euro stove use 5".

I have heard that you can reduce a 6" flue exit to 5" in right out of the top of the stove is this ok to do?

I think the rules say no. Reality is it depends. How many btu is the stove, how much air does it draw, how tall is the stack with how many bends, what is the outside temp, how hot is the exhaust, what is the temp at the top of the chimney, how tight is the house? I have seen it work and I have seen it not work, and not the way you would have guessed.

Biggest legal issue is probably homeowners insurance, you need to stay on their good side.

Is it because of an existing 5" flue? If so, can you give details on height, bends, type of pipe and insulation. I understand the financial desire to reuse a flue, but it needs to be able to handle the output of a new stove and probably meet the specs to maintain insurance.

The reason why, is because I was able to buy all required stainless steel double wall insulated pipe, brand new for a very low price. I did some research and found that some stove manufactures like pacific energy have tested their stoves to work well with 5" but they UL test with 6" because it is more common. The flue run will have 2, 45 degree elbows and will be about 30 ft up through the roof.

The house is not that modern it is 30 years old. So it is not super tight.

If the install is certified how will it create an issue with insurance?

actually it will be more like 16 to 20 feet high

Ok. Cool

One gotcha could be if the Canadian or insurance rules say no reducers period. I have seen it here.

I think Woodstock soapstone work with a 5, and Jotul will as should most of the lower btu from anyone. Those I have seen set up with fives, but more like 50+ foot stacks.

Do you have a link to the Jotul. I checked their website and could only find 6".

I don't, but I have seen it done successfully with one of the smaller ones.
