i have the ldj furnace to go in my shop and have not started yet but want to hook up the power vent and go straight out my side wall. the base of the power vent is just a little bit wider than the sheet metal corragation spelling, I will cut it down , unless i can find a adapter first. does anyone know of a way to mate it to the wall and be sealed tight without cutting I think i can trim a little bit off each side and drill new holes and fit on sidewall without leaking:laugh:

I cut the hole so the rib was centered,took 3/4 plywood same size as the vent,cut hole then split it and fit it to the center rib. lots of silicone and screwed it on. It's not pretty but has not leaked. Just to mention it's on the back side of shed and nobody sees it.

thanks for the advice i will try either wood or some metal so it will last. Looking at your picture i was wondering why it looks as your power vent is up higher than your exhaust on the back of the furnace.You have 2 elbows , can you run the exhaust pipe a straight run out the shop wall and maybe up hill alittle for a draft if power goes out or do i need the vertical run like yours with some elbows? thanks for any advice .

To keep it close to the wall,get the draft damper in and keep it high enough so somebody didn't touch it and get burned. Don't know if my reasoning was right but it works good. Make sure you go out and blow the junk out of it about once a month. I also have a UPS on the power vent that will run it for about 5hrs in-case of power failure when I'm not home to get the generator running.

Tractor, did you find a solution to installing the power vent? Hope everything is up and running for you. Great heat in a shop once everything gets set. I found with the powervent that .035 idle fire and .01 with combustion air running on the manometer is a good combo. I also mix about 30% pellets. Wish I could burn all corn but the clinker build-up in the burn pot makes for poor efficiency. Good Luck.

yes i got it going . sevan days and nights straight and no complaints .Bought it used last winter and and there is no comparison to the 7100 amaizablaz. Never got much heat out of that one. I bought one inch box tubing and made a plate for the outside of my shop. I then bolted the plate to the exhaust fan and then screwed the fan to the shed wall. i added 2x6 on the inside to strengthen the wall support. I then cut a circle in a piece of plwood and screwed it the the wall support, taped all the seams with the foil type tape used for exhaust on water heaters and it works well. it has not got real cold yet but i really like the power vent and can warm the shop very well.
