Separate Combustion vent kit install.

[samert111]

I recently purchased the Beacon Morris BRT-75K shop furnace along with their separate combustion concentric vent kit for my PB. The kits rectangular box is only 5 1/2" thick and since I'm going out horizontally thru the wall I was considering installing it inside the wall between 2 studs and then putting the interior OSB sheeting over it to basically hide it. Normally they are installed up against the wall inside the building. I know I will then need to cut 2 holes (1 for the exhaust duct and 1 for the combustion air duct) vs. just 1 in the interior OSB sheeting but I think it would be a much cleaner looking installation. I'm using 4" double wall "B" vent for the exhaust and it goes out thru a 6" pipe in the vent kit so all the clearances to combustibles will be met.

Anyone see a problem with this?

I am thinking about doing the same thing. Did you end up embedding the box in the wall?

I don't think that is a good idea at all.
The box, provides the needed separation from the combustible surface (the OSB), and the exhaust vent. Cutting a hole for the exhaust vent to pass through the OSB sounds like your exhaust will be unacceptably close to combustible materials.

You are right Dumb idea. Thanks
