I have a older Bryant gas (propane) unit hanging heater it is 140,000 btu output heater model 175-327. I am wondering what is the best way to vent this heater. I am aware the hot air is supposed to rise with the gas out the pipe. It is in a hip roof barn and i would not like to go through the roof if at all possible?!? Can I run horizontal and put a blower in it? I am tied for space to go up. And what kind of pipe do I use? It is a insulated barn with 2/4 walls and plywood on inside and siding on out. The bottom of the rafters is 10'. Any help at all would be greatly appreciated!!!!
Thanks!!!!
