    Iam redoing my stove pipe using Security Secure-Temp double wall pipe (matches the class A). From the ceiling box down I need a 45, 18" straight, 45, 30" straight and stove adapter. They don't make a 18" or 30" straight so I want to use a 12" straight and 3-9" adjustable for the 18" run and a 24" straight with another 3-9" adjustable straight then the stove adapter. This going into a nc13. Is it ok to use two adjustable pipes? Just want to make sure before I order.

    Use as many as you like...they're all rated for use in the flue from stove to the transition to Class A chimney. Once you get it assembled just the way you want it, it's a real good idea to put three screws in those adjustable sections where they end up overlapping, just as you do in all the other piping connections.

    I had to use two curved pipes back to back to get the right angle after replacing my Vermont Castings coal stove with a Pacific Energy wood stove. I was worried abut poor draft or smoke pouring out around the seems. I've fired the stove several times and haven't had any problems.
