I have the seperated combustion unit in my garage. Its not just a matter of efficiency, its more a matter of a sealed chamber if youre using it in a dusty area or if you spray paint in your shop. The sealed unit draws the air from outside instead of the overspray filled air in the shop. And the only problem Ive had is the control board. I had no idea theres been a problem with them but Modine sent me a replacement board free since the heater was less than 2 years old. It turned out that the original board had a cold solder joint on one of the pieces. The HVAC guy that installed the heater for me found the problem, resoldered the piece, and its worked fine since. I still called Modine and they sent a replacement and told me to keep it as a spare.

No it could be mounted with vents on left or right side. Sticker was already on
since then I have peeled label off.
