Part of the Arctic kit was a heater that attached into the exhaust system exactly like a muffler(Silencer for y'all....)
It had two (Inlet and outlet ports) for cab air that was ducteted to the windshield(Translation...windscreen)
See Scan.......
This device is a sealed heatexchanger and does NOT use exhaust fumes for heating direct...
I tryed to scan an image but file size too big..I cut it down to 60% and was still too big ..I'll work on it later...Work time ...gotta go...
