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.

This was so much easier than looking everywhere locally for these parts. Thank you ACF for having all of the pipe and fittings I needed to vent my Sterling heater!

High quality materials good value
