I am putting a wood burning furnace in my new shop and have seen rules on single wall stove pipe that it can not be over 10 total length. I thought I saw this for Canadian, does this apply to US also? The shop ceiling is 16ft, furnace pipe comes out about at 4ft so it would be about 12ft, then a T and about another foot to connect to the outlet of the furnace. Is it OK to run single wall pipe for this, or would double wall be required? Just want to set things up right.
Thanks.
Thanks.
