The maximum length of an exhaust system
depends upon the type of vent used, the num-
ber of elbows, and the type of exhaust hood.
The maximum lengths for both rigid and flex-
ible venting is shown in the chart below.
For exhaust systems not covered by the ex-
haust length chart, see the Whirlpool Service
Manual: "Exhausting Whirlpool Dryers," Part
No. 603197, which is available from your Whirl-
pool parts distributor. Also refer to Section 8.
If a dryer is installed in a confined area, it must
be exhausted to the outside, and provision
made for enough air for combustion and venti-
lation. Check governing codes and ordinances.
A 4" (10.2 cm) outlet hood is preferred, how-
ever, a 2 1/2" (6.4 cm) outlet exhaust hood may
be used. A 2 1/2" (6.4 cm) outlet creates
greater backpressure than other hood types.
For permanent installation, a stationary ex-
haust system is required.
