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 *****
