With a basement install I need a 3" pipe for the outside air intake but the pipe on the stove is only 1 7/8", and I can't find a reducer that would work. Has anyone else had this problem and found a reducer or worked it out some other way?

thanks.
 
Smitty, try a auto parts store.....exhaust pipe reducer. if not, maybe a muffler shop that bends their own pipes...they usually have an expander tool to make smaller pipes flare out.

Give Eric at Kinsman a call....he may have something or know of a source if the auto parts thing doesn't work out.

IIRC from mine a 1.5" PVC female connector was a good fit. I'll check the size later and let you know for sure.

This is a mistake you shouldn't make, the air intake is technically part of the exhaust system and must be metal.
 
...and its probably better to expand up to dryer vent size, so there are more options with parts a nd hole drillin' will be the same size too.
 
I bet you can do it by taking in the pieces to a plumbing supply and show it to the counter guy. If they can't for whatever reason NAPA seems to be the auto parts supplier who has the greatest number of fittings around here for the odd stuff. If that won't do it try a custom hot rod or similar or truck shop. Those tend to be the places that have heavy pipe and benders. Such things are out of style today but the custom places still use them. Too bad you can't use pvc. My stove only gets nasty cold along that intake line and very wet with condensation. Plastic would surely last longer than steel.

Yup and 99.999% of the time it is likely to be fine, however it is against code and considered a safety hazard.
