Question on parts needed for selkirk supervent install.

[russell1047]

I'm going from a main floor into a living area that was an attic at one point and then through an 11/12 roof. I know I need to enclose the chimney on the second floor. But I'm having trouble getting a straight answer from the instructions on what kind of shielding I need. Since it is enclosed below the roof I need the Rafter Radiation shield for the roof. Now for the ceiling/floor I'm confused if I need the Firestop Rad Shield/Joist shield and the decorated ceiling support. Does the support fit with the joist shield? Figure 10 shows no Joist shield needed so I think that's correct but i have true dimensional 2x10 joists at that level. Will the rafters be protected by the framing and the ceiling support? Or should I try the joist shield as well?

Bonus questions. I have a cathedral ceiling support. Can I just completely nix the Rafter shield in the roof for the CCS since it allows pass through of the chimney pipe? Would the CCS being enclosed be an issue? I kind of like the idea of using the insulation in the CCS to prevent cold air from seeping in. As for the enclosure, should I insulate it or should I use the Insulated chase plug?

There may or may not be issues. It would help to have a picture or two of the interior view of the installation area and a simple diagram of the proposed install.

have you tried contacting Selkirk? there's an online form for email support (at least on the Canadian version of the site). They usually get back to you within a couple of days.
