I decided to do self install on a GG75 heater and had looked around a many sites w/ the heaters and exhaust parts I'd need. I found others who had done a self install and they recommended ACF Greenhouse kits, and I have been completely satisfied by the kit and instructions. Everything you need and some pretty well documented instructions are included. All parts are good quality and I was able to piece it together without any problems.

Everything in the kit I needed to install for the configuration I wanted on my sterling heater. Seams to be of good quality. Instructions were detailed so could understand. Thank You

Good quality material. The connections were fairly simple. I had metal cutting tools and had done some duct work before. Took me 2 days to complete installation.

The kit is first class, very happy with it. Will recommend it.

Just finished getting it in, working good.
