Hey Russ, where do you get the double walled burner vent duct work? That would be much more effective than what we are using! Do you sell that?
Thanks guys. The only thing comparable I've found around here has been in the 2-4 inch range... only for gas hot water heaters and hvac systems. I currently use something meant for automobiles...
