This kit from ACF greenhouses was top notch and very easy to install. I originally ordered an extra 45 deg angle, but where my heater ended up landing I needed the 30deg elbow. The kit was very easy to install and the piping is very high quality. I would recommend to anyone installing a furnace in their house or garage

   

product was as described and was shipped quickly

Product arrived with no damage to my residence. I ordered an extra 3 inch vent section of 18 inches as I knew I was a little further from my back wall then some who install their heaters. I also ordered the firestop piece of stainless steel and the stainless steel storm collar. I did not like that the wall thimble on the outside of the building only has about 1 inch of flange around the eight inch diameter outer pipe. Knowing how much rain and wind we get here in Washington, I put the firestop over the wall thimble flange to help combat wind and rain around the eight inch hole that I cut in the side of my garage. I then also put the storm collar around the pipe as well. Maybe a little overkill, but water will not be getting into my shop through this vent pipe. Picture of outside and inside install attached. Everything fit like a glove and went smoothly. Expensive stainless vent pipe, but I think it was worth it.

 

I was looking for a vent kit with a thimble which would work with 2x6 stud garage walls and one that met or exceeded national safety codes. This kit worked nicely and I was able to customize my installation with the purchase of an extra vent pipe. The only thing which I could suggest is a trim plate to cover the outside thimble.

After many hours of trying to figure out how I was going to vent my new hot dawg heater, I purchased the Modine HD Category 3 Horizontal Vent Kit from ACF Greenhouses. Everything from purchase, to delivery, and install exceeded my expectations. Could not be happier with my experience from them. I highly recommend working with this company and their products. 5 Stars *****

Installation very straight forward, parts appear well made and being stainless is a big factor.

I like the seals between the pipes, much better than just a clamp.

Flanges on thru wall thimble folded completely over. Shipping box in perfect condition. Had to be packaged that way.

ACF Greenhouses: I'm sorry part of your vent kit was damaged. Please contact us, and we will have a replacement shipped out to you no charge.

Went together easy and looks nice. Thanks ACF! Could not find locally.

Very happy with the kit. Seems to be of high quality. Would be 5 stars except three corners of my wall thimble were bent.

I purchased a prepacked 4" stainless steel vent kit along with some additional parts to complete the installation for a hanging furnace in my 40' x 45' hobby garage. The order was shipped immediately and arrived in perfect condition. The kit also came with their "red envelope" of installation guidelines which were very helpful. During the installation process I needed a longer pipe and that was shipped immediately as well. The folks at ACF were great to work with and allowed me to return the pipe from the kit that I didn't need. I highly recommend working with these folks and the ACF Greenhouse Company.
