Modine HD Hot Dawg Heater Category 3 Vent Kits

Good product, instructions were helpful, stainless materials should last a long time.
Quick delivery, too. Would recommend.

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 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 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.

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

Shipment came within three days, intact; installed easily, high quality SS, part tolerancing made for an easy flexible, positive, fully sealed integration, works well.
On the slightly negative side, thimble not well designed (as other thimbles are) for installation with vinyl siding. Had to build it out 3/4' with PT plywood to fit nicely w/ j-channel. ACF customer service engineer provided that idea which worked out well. Thanks for that. I don't love the notches on the thimble where the tabs are bent as it doesn't make for an elegant design and requires a bit of caulk to seal, otherwise no real complaints.

 

I was impressed with this product with quality and the speed of shipping from the supplier.
