I have a spare piece of 6" class A double wall insulated pipe 36" long. I need to extend my chimney (same pipe) 15"downward to rest in my support box. Can I cut the female end off the spare, or must I buy a 12" section plus a sliding adapter to the tune of 200 + dollars. I realize I will have to adapt the flue extender, and the warranty will be void but the chimney was here when I bought the house so it's probably not available anyway. I suppose I could sell the spares (have 3) to pay for the new pieces but I'd rather keep the loot. What do you think?
