I'm going to look at a used stove tonight and it has a 6" outlet. My chimney is 7" and is outside.

Legally is this combination allowed in Canada? From what I can see online it seems ok but I'd like to make sure before I spend my money.

Thanks
 
What does the stove manual say?
 
I don't have the model number so I can't check.

Does the manual trump the rules or do the rules trump the manual?

I believe it was a USA rule I found that showed it was legal but I'm in Canada so that doesn't really help.
 
The stove manual in this case is the guiding document.
 
Yes almost all regulatory bodies in Canada will ask you to follow the stove manual. Mine reads:

Your wood stove will provide optimum efficiency and performance when connected to a 6-inch diameter chimney flue system. The connection to a chimney having a diameter of at least 5 inches (Canada only) or no more than 7 inches is permitted, if it allows the proper venting of combustion gases and that such application is verified and authorized by a qualified installer. Otherwise, the diameter of the flue should be 6 inches

But off course your stove may be different.
 
Much thanks. I will ask the seller for the model number before going and taking a look. Hopefully I can find the manual.

I don't think this is the case here, but if this is a tagless stove, what does the rule state about chimney sizing?

I'm not sure.

But if it were me it wouldn't be going in my home, way too hard to prove proper install and clearances chimney height/diameter and proper operation without a manual to follow in the event something goes wrong and insurance starts asking questions.

I went and looked at the stove, it was way too small for my application. It did have the sticker on it though.

My brother loaned me his spare stove to use for the season. This is a simple install in my unfinished basement so clearances or aesthetics aren't an issue. I plan on having it inspected regardless of what insurance says. That's cheap insurance in my opinion. I'll be installing a FW3000.
