My used Jotul woodstove appears to have a 7" flue outlet. Does class A pipe come in this diameter?
By Tyler on December 6, 2013
Yes, we carry single-wall stovepipe (DuraBlack) and class A chimney pipe (DuraTech) in a 7" inside diameter. If you want a full quote for a chimney system for your Jotul stove, please fill out our Chimney Pipe Design & Quote Form

I have a wood-burning cast iron stove in my workshop with a six-inch outlet that I want to vent through a pre-existing 8-inch outlet in my roof. It's about 12 feet from the top of my stove to the roof, and the pipe is passing through open ceiling joists. What do I need in order for this to be a safe and proper installation?
By Kevin on January 3, 2013
Answer:It is recommended to vent any appliance only with diameter of pipe common to the flue outlet. Increasing from the stove's 6" collar to the 8" chimney could result in a poor draft or increased creosote buildup.
In order to recommend components to achieve this transition, we need more information regarding the existing components. Could you please reply with the manufacturer/brand of the existing chimney system? This information is necessary in making an accurate recommendation.

Does 10 inch Class A pipe need to run through a thimble on a rubber covered corrugated steel roof?
By Tyler on March 19, 2013
Answer:No, but the pipe will need 2" of clearance all the way around it as it penetrates the roof. There are rubber boot flashings and dead-soft aluminum flashings available by some class A manufacturers for the top side of the roof after penetration.

Can you connect twist lock pipe to MetalBest pipe?
By Collin on November 11, 2013
Answer:MetalBest Class A chimney uses twist lock lances that are specific only to the MetalBest product line. As such, other brands will not attach properly.
