A/C plenum installation

I have a 1995 Newmar Kountry Star. While waiting for my Brisk II a/c to arrive, I am trying to install the A/C plenum I received from Newmar. The original plenum was holes in the roof with sheet metal plates formed into a plenum to divide the exhaust and return ducts. The plastic plenum I got from Newmar appears to require a reciprocating saw to make the hole big enough to fit. Also the aluminum 1"x1" plenum support will not span the rafters. Has anyone done this before? Can someone please help?

I would suggest calling Newmar and see what they say.

I already called Newmar. They sent me the instructions on how to replace the plenum. Their directions are for a unit that already has a plastic plenum to replace with updated version. My unit will require some kind of modification for this to work. I emailed Newmar with the pictures and await their reply. I was hoping someone on here that has faced this problem would reply. Thank you.

Obviously, your style setup, doesn't match the new stuff. A 26 year difference is a long time to have something stay the same. I would wait for the Brisk Air to arrive, see how the discharge is setup and then you'll have to modify or custom make your own. Maybe a large piece of tin, larger than the plastic plenum, can be used as a base, then cut in the same holes the plastic plenum uses.

Worse case scenario, get a local fab shop to make one out of tin.

A/C plenum installation

The Brisk II and Blizzard have the same configuration for both flow directions.

Hereís a picture of my Blizzard before we installed them. You can see the inlet / outlet pattern.

The key is to make sure that the intake DOES NOT MIX with the COLD OUTPUT.

If those two are separated you'll be fine. So currently your cold input looks to be separated and ducted into your coach and your intake seems to be ducted also into your coach. The poster with the Brisk AC shows a separation caused by the attached gasket. Just do everything you can to streamline the intake as well as the output and prevent any possible mixing of the two. The new black plastic piece needs to be placed properly to follow the Brisk Gasket, and the output of it needs to be made separate from the intake underneath.

A/C plenum

I had to measure the "new" plastic plenum. I laid out the dimensions of the hole. I used a jigsaw with a short blade to cut the hole out. I got some 1" aluminum square tubing and 1" angle from Lowe's. I had to make two 16" braces and install them flush with the sides of the hole. I was then able to install the 1" aluminum brace I got from Newmar to the 16" braces I fabbed. Fastened plywood strips to crossbrace to make flush with the roof. Installed the new plenum and foil taped the ductwork in. Still awaiting my new unit. Thank you everyone who responded. At first I was worried, but I'm comfortable with the outcome.

GLAD you got it done. Now the easy part will be the install of the unit itself.
