Getting close to finishing the BKK alcove build and hook-up. Using Majestic SK-8 double-wall pipe. The 12" length section you see in the picture is 4" too short. The 18" section I have coming in will be 2" too long so I plan on carefully trimming 2" away with tin snips. You can also notice that the OD/ID of my inner 8" wall is the same as the BKK flue outlet.
1.) Height - Is my trimming technique a good idea? Unfortunately Majestic / Monessen does not make telescoping parts. I have 2.5" of stove flue outlet height, and about 1" of vertical play if I push up on the entire chimney.
2.) Diameter/Fit - Is it ok to cut two short vertical slits in the 8" inner pipe to allow fit over the flue outlet? My goal is to have this slit completely pushed down over the outlet so there is no air gap, but I am not sure if this is realistic.
The 18" part should arrive today. All side (10"), rear (6"), and height (49") clearances are met using the rear and side shields. Thanks for your help! - Jon
