NC-13 clearance- get it as close as possible!

[Beetle-Kill]

So the new stove is on it's way. Now I need to vent it. It will have to go out a wall horizontally to a "Tee", then up about 16-20'. Not too worried about that, it's the interior I have to contend with. Ceiling height is 74" from floor. Stove is 27.5" to top of flue pipe. What are the thoughts on running a flue/damper collar, a 45 and a 45 to a thimble, straight run to the "Tee", then up from there? I'm thinking the damper is the only area for single-wall, all else would be double wall pipe.
Due to requirements, can I double the heat shields on the back of the stove? To reduce clearance requirements, will adding extra air gaps help? I don't plan on adding a blower to this stove, so "over-the-top" heat shields are cool with me. I will use Eco-fans on this one, however. (Base-3" concrete/slab on grade, back wall is 24" CMU w/ wood framing up to 72".) Thanks, JB

Contact Englander tech support for clearances to the ceiling. 74" is a very low ceiling. There is a min. of 84" required for alcove ceiling height. There should be no need for a damper on this flue pipe. The clearances can't be reduced further than permitted in the stove documentation. If there is a cmu wall behind the unit, can the wood framing be removed for a section wide enough to cover clearances?

I agree, 74" ceiling height is not ideal, but that is what I have to deal with. This area can be modified , there are no limits, and aesthetics are not an issue. I can stack heat shields as required, , and the through wall area will probably be cut-out/ replaced with steel and fireproof insulation. Steel stove means I can weld on threaded studs for additions, (heat shields). The damper is only an idea, I don't know if it should be there or not, but I have to figure the dimensions of the component pieces . I don't want more or less than 1/4" per 12" of up-angle on the horizontal run.
