Class A install question

[southbalto]

I'm going out the back of the stove to a finishing collar, through the wall with a thimble and into a tee in the exterior chase.


Couple questions:

I need to use elbow(s) to offset the pipe about 15" to the side for the run up the chase. I was wondering if it would be acceptable to rotate the tee to to get the flu running in the direction I need and connect it to one 15 or 30 degree elbow for the run up the chase. I guess the other option is to keep the tee vertical and buy two elbows to allow for the offset.

Also,

I'm picking up a chimney support that I'll attach to the wall. Since I have an offset coming off the tee, I was thinking of putting the support after the offset(s) (where the bulk of the weight is going to be). Do i need another support block under the tee in this case? Below the first wall support would be one or two elbows, a 24" section and the tee. I'm wondering if that weight required another wall support.

I'm working with my FIL who has a background in HVAC. His commercial distributor stocks MetalFab Class A Chimney products. Any good/bad experiences with this product?


Thanks all. Happy Holidays

If understand the first question - you want to rotate the class A tee to get it going in the right direction - which is exactly what I am considering.

Honestly I would not advise unless the manufacturer says it is okay to do so - but if you think the T is suppose to support the weight of the chimney with the TEE support bracket, we'd be side loading the chimney rather than a vertical gravity effect (that make sense ?)

Didnt see any replies...have you made any progress or anything new to add ?

Thanks for the reply.

I did the install back in December. It went pretty smooth.

As you can see the bottom 6' of the stack does lean slightly. I don't think it's a major issue though.
