Your Garage Heating System

The reason for my asking to see photos of others heating system set-ups is because I am currently running my gas line and have a York Diamond-90 gas furnace but not sure on the set up. I would really like to hang it put not sure if that is possible...

Depends, is it an upflow, a downflow, or a horizontal?

If you have a corner available you can "burn" for room, then a downflow might be feasable.

Upflows are not normally that practical in a garage, because you must elevate them to get the burner/ electrics "off the floor" for safety, (regulations may vary, about 2') and then your discharge is "way up there."

If it's a horizontal, yeah.

Now, this is a 90% which I believe vents with PVC, but I'm not familiar with these, does it have a SEALED dedicated combustion (fresh air) inlet?

Also, be aware, that a condensing/ 90% furnace MUST not be allowed to freeze. This means that once installed, it must ALWAYS be working in your garage to keep it at least above freezing.

I assume you got this used? I would not necessarily install a 90% furnace in a garage, for the above reason.
