I am installing a new wood stove (EPA Cert.), have mechanical permit, etc.

And I have built my hearth pad (proper R-Value to code, etc.) and have
located my wood stove on the hearth pad to manufacturer's specs. (Proper
distance from walls, etc.) This is the *only* place the wood stove can go.
The chimney is stainless steel 6" inside diameter and 8" outside diameter.
I'm Using Selkirk - Metalbestos chimney parts.

So guess what? The metal chimney going straight up will go right smack dab
through a rafter (45 deg. roof slope - one of many 2 x 4's at 45 deg. angle
supporting roof.)

So I will need to cut the rafter....

Questions....

Can I cut the rafter, then add 2x 4's which transfer the support for that
rafter to neighboring rafters?

I read that there needs to be a 2 inch separation between wood and the
metal chimney. If I do this where the chimney pops up through the roof,
there will be a 2" air gap going from the attic to the vented roof jack
(flashing). I am concerned about insects getting into the vent, then making
a home in the attic. Can I place screen or something somewhere in this area
(to keep insects out)?


There's not a lot of extra strength in a 2x4, I would not want to add
additional loads to the flanking rafters without reinforcing them.

Buy an adjustable elbow or two, and run the chimney so it avoids the
rafters altogether. It's a much easier and better way to do it.
