I bought this horizontal vent kit for my Modine 45,000 BTU Hot Dawg heater. The piping fitis excellent and goes together effortlessly. The piping fit the 3" exhaust of the Modine perfectly. This is a high quality kit.
I am so glad I found this ACF Greenhouses vent kit! I had planned to built a vent kit from scratch but this is so much better with it's integrated gaskets and clamps. The thimble worked well, too. Extremely pleased with this setup.
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 *****
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.
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.
