Older Unit heater Venting qeustion
Ive got an older atmosheric type gas fired unit heater that I got from and old warehouse I used to work at and now I want to install it in a garage, My qeustion is I am not super familiar with venting and such and I want to make sure I do it correctly, There is no chimney and im looking to direct vent it out the side of a wood constructed building. How do I know if I need a power vent or not? what type of vent pipe do i need? Normally I would follow manufacturers reccomendations but due to the way i obtained it i am unable to find any info on it, Any help would be appreciated thanks.
