Tip & How-To about Whirlpool GEW9250 Electric Dryer
Here’s some useful guidance for installing dryer
ducting. Improperly installed ducting
can cause the following:
GAS DRYERS – Rapid burn cycling and improper drying results.
ELECTRIC DRYERS – Premature Heating Element failures.
IMPORTANT! NEVER terminate ducting in a chimney, under an enclosed crawl space or attic, and never common a dryer duct with a kitchen exhaust.
The total length of ducting and number of turns should be kept to a minimum. Semi-rigid metal type ducting is strongly recommended as it is more durable and resists collapsing.
If connecting sections of ducting, all joints should be tight to avoid leaks. The male end of each section must point AWAY from the dryer to prevent lint from accumulating at each junction. Ductwork should NOT be assembled with screws or fasteners that extend INTO the duct as this also will create points where lint will become snagged and accumulate. Wrap overlapping sections of ducting with duct tape.
A screen should NEVER be installed over the exhaust duct termination. The preferred termination is a dampered wall cap having a 4 inch opening. It must be installed a minimum of 12 inches above the ground.
Maximum Length of Metal Duct:
# of 90 degree elbows 4” Semi-Rigid 4” Flexible
0 58 ft 28 ft
1 48 ft 23 ft
2 38 ft 19 ft
3 29 ft 17 ft
4 21 ft 15 ft
NOTE: It is recommended that you inspect your dryer ducting periodically to ensure you have no lint build up. Excessive lint can present a fire hazard.
