CAUTION
Concerning air-intake side distance "A" (Fig. 5a)

The minimum for distance "A" is 6" if there are no
obstructions on the air-discharge side (wall *1 side)
and *2 or *4 is not present. In all other cases, the min-
imum for distance "A" is 8".
If wall *1 is on the air-discharge side (Fig. 5a), or if
●
obstructions are present on all 3 sides *2, *3, and *4
(Fig. 5a), then the minimum distance for "B" and "C" is
39-3/8". Even if there is no wall on the air-discharge
