Dryer Ducting Installation Tips

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.

Convert from gas to lp

This is going to result in you needing a different metering orifice on the gas valve. There are LPG kits to install this, but I highly recommend a professional to eat the liability on this one because LPG is heavier than Natural gas and if it's installed improperly, a leak will cause the gas to settle on the ground creating an explosion hazard.

My dryer takes much longer to dry loads now


You need to check the following things to sort out the issue you are facing with--

Improper sorting •Separate heavy items from lightweight items (generally, to dry a well-sorted washer load is a well-sorted dryer load).
Large loads of heavy fabrics •Large, heavy fabrics contain more moisture and take (like beach towels) longer to dry. Separate large, heavy fabrics into smaller loads to speed drying time.
Controls improperly set •Match control settings to the load you are drying.
Lint filter is full •Clean lint filter before every load.
Improper or obstructed ducting •Check installation instructions for proper ducting/venting.
•Make sure ducting is clean, free of kinks and unobstructed.
•Check to see if outside wall damper operates easily.
•Check the Installation Instructions to make sure the dryer venting is correct.
Blown fuses or tripped •Replace fuses or reset circuit breakers. Since most dryers circuit breaker use 2 fuses/breakers, make sure both are operating.
Overloading/combining loads •Do not put more than one washer load in the dryer at a time.
Underloading •If you are drying only one or two items, add a few items to ensure proper tumbling.

burning smell coming from the dryer!

You have a serious clog somewhere in your dryer exhaust ventilation. I would recommend you STOP using the dryer immediately and clean both the interior and all the vent ducting from where it exits the dryer to where it exits the home. the burning is coming from lint build up in and around the heating element and its beginning to smolder. This is a potential fire hazard and may end up causing the heating circuits to fail. The condensation comes from the the inability of the hot air (which is mixed with humidity from your clothing) condensating inside the vent duct. The lint starts to collect and get wet to the point of saturation. Then it begins to cause water to form and leak out of the ducting and on to your floor. You do not want this condensation inside the dryer where the heating circuits are. The following link will provide with some guidance for future reference:


Pay particular attention the paragraph where it discusses proper dryer ventilation. I hope this helps you. Let me know if I can be of further assistance.

Most dryer heat problems are associated with clogged, or improperly installed ducting. It's much easier to rule out the external causes before inspecting the dryer interior. I hope you find this information helpful. If you need further assistance, please post back and let me know.
