Manufactured Home Wood Stove Installation Questions.

[mellis2188]

Hello,
So I bought a manufactured home back in April. The home came with a Vaxar Fireplace that I uninstalled and I built a hearth for a wood burning stove. Everything is to specifications for the stove placement per the manufacturers label on the back of the stove.
See before and after photos
So now its time for installation of chimney and stove pipe. I have a photo I drew up (sorry for the not so straight lines) of the things I have and what I think I need. I wanted to use the existing 12" single wall pipe so I would not have to change anything at the roof as far as flashing went and just run a triple wall pipe up the center of it. Code for a Manufactured home is Double wall Stove pipe and Triple wall Chimney pipe. Can I do this? Also, can I maybe put the Triple wall all the way through the 12" out the top, put a chimney cap on the triple wall and make some type of flashing to seal the gap between the triple wall and the 12" pipe? Or am I going to have to tear everything apart and take the 12" pipe out? I need some serious help here...
Thank you,
Michelle

Sorry to tell you, but if you're gonna get this install approved, you'll hafta remove the air cooled chimney sections.
Install the ceiling support box, connector to Class A adapter & then your Class A all the way to the cap.
You might be able to get away with an oversized storm collar on your existing flashing & the new Class A.
The ceiling support box will probably need an extension on it to get all the way to the underside of the roof
sheathing & the extension will also act as an attic insulation shield.
I wouldn't use those 90 degree connectors either. 45 degree elbows will give you a better draft.

Note that you don't have to use triple wall chimney, it just has to be class A chimney pipe. There is good quality double-wall, class A chimney pipe out there as well.

in my mfgd home ive the same piping in ceiling as during jpg mine was/is 12 in stainless with these silly standoffs and 8 in od runnin up the 12.. I removed thee 8 in and standoffs. and ran my class A straight up thru center of thee 12 I used one or two standoffs to keep my class A centered .. so the outside Dia of my class A is two inches away from my stainless chaise my class A is locked and banded .. theres no way I see Id need to mess with the Chaise's square to round ceiling adapter other than to make it look nicer .. my dang class A can take an explosion in er and be good .. IMHO anyway..
