I plan on cutting off. on top I have a square insulation box which has the black bag insulation ducts running out from it. can I use this with the hyfire 2 and if not what kind of ducting would I use . I'm going to be placing this in my basement and its an older home. Hoping I can still use the existing ducting somehow. if you have a brand and type of ducting I should look at that would also help. thank you for your help.
Just a note to check your local fire codes. Most (not all) localities or insurers use the National Fire Protection code (NPFA).
The NPFA requires automatic fire dampers on any ducts passing through floors and you may end up with no or voided fire insurance, not knowing it until after a house fire. See Topic
