CAUTION
Concerning inlet-side distance “C” (Fig. 1-4)
The minimum for distance “C” is 6" if there are no obstructions on the outlet side
(wall *1 side) and *2 or *4 is not present. In all other cases, the minimum for distance
“C” is 8".
If the unit is installed with the outlet side facing wall *1, then there must be no obstructions
on 2 of the remaining 3 sides: *2, *3, *4.
If wall *1 is on the outlet side (Fig. 1-4), or if obstructions are present on all 3 sides *2,
*3, and *4 (Fig. 1-4), then the minimum distance for “A” and “B” is 80" (Fig. 1-5). Even
if there is no wall on the outlet side, a minimum of 3.3 ft. is required.
