Best way to deal with 4 inch offset in Jotul Castine Install?

[lumbering on]

Will be installing Jotul Castine.
Into existing fireplace, exterior masonry chimney, with existing full liner, uninsulated.
Liner length is 30 to 35 feet

Due to limited depth of hearth, stove will be partially recessed into fireplace.

If most of the stove is to outside of the fireplace: the existing liner termination, and top exit of Castine, will be 4 inches apart, measured from back of casting top exit to front of liner.

Looking at two solutions,

1. Use rear exit, and T-pipe with clean out.

2. Use top exit, and two 45 degree pipe connectors

Not sure if any of this is possible, as I am not sure of the dimensions of the available connector pipes.

If both are possible, not sure which is the better method.

Any thoughts would be greatly appreciated.

See diagram.

This stove requires strong draft for rear exit and it sounds with a 35ft. tall pipe you will have it. That's what I would try at first.

I was looking at the T Pipe connectors at Woodland direct.

Do you know if the dimensions/sizes of available standard T pipe connectors will make this an easy job?

Not certain but it should be with a short single-wall connector. Be sure to pitch the horiz. connector uphill at least 1/4" / ft, 1/2" / ft is even better.

Would the two 45 sections make cleaning easier?

It would seem the soot would go straight into the stove vice the bottom of the tee. Might save some work each year.

If you have the vertical height to make the 45 transition do it. Everything will work better. BG is correct though with that much liner (once you finally get it hot) draft should be ok either way. Use stainless or at a minimum 22ga welded connectors and do the job once.
