Hi All, I have a new Pelpro PP70 that we purchased for a remodel in the foothills of Colorado at 8000 ft. It's a corner installation on the main floor of 1300 sf upstairs area (fairly open design) and was going to vent it straight up (no horizontal except for clean out "t") and will be inside using the code-required 4-inch PelletVent Pro venting & installing the required fire prevention vent accessories for the ceiling /attic (e,g. shield through roof). It's a 5/12 roof.. There's also a ceiling joist about 12 inches (standard 8 ft ceiling height) from the corner so it's kind of tight and may require a couple 45-degree elbows to make it all fit. Again, installing a clean out "t" on the back of the stove. However, I'm kind of stumped as to the exact height I need. The Pelpro manual says a minimum of 11 ft vertical with three 90 degree elbows (counted each 45 elbow and "t" clean out as 90s with minimum of a 1 ft equivalent to straight pipe for the 45s, and 3 ft for the 't' ) and that's with up to 2 ft horizontal (there's no horizontal, just vertical),. Also following the 10/2 rule. However, on a Canadian site, I was shocked when I saw that an additional 2 ft of vertical run was need for each 1000 ft increase in altitude. That would make the stack ridiculously high...like three stories high! Any thoughts from you other members with high altitude experience? Thanks in advance.
