OAK for a Lennox Montage

[sawdust1]

Would a run of about 14 feet to 15 feet be to long for this set up? Would come off the stove with a 45 then use a 90 to continue the run to outside wall then use 45 or 90 to end run.

Length of run and use of 45's and 90's has more to do with the venting of the stove and not the OAK. You should be fine.

Thanks for the reply.

Had this discussion on another thread - length and bends in OAK will constrict airflow into burn chamber of pellet stove and should be up-sized similar to exhaust piping.

Based on this you would need 4" pipe to comply. Your EVL is 23.5. I guess in retrospect I stand corrected.
