Exhaust system requirements, continued
In installations where the exhaust system is not described in the charts, the following method must be used to determine if the exhaust system is acceptable:
1.Connect an inclined or digital manometer between the dryer and the point the exhaust connects to the dryer.
2.Set the dryer timer and temperature to air fluff (cool down) and start the dryer.
3.Read the measurement on the manometer.
4.The system back pressure MUST NOT be higher than
0.75 inches of water column. If the system back pressure is less than 0.75 inches of water column, the system is acceptable. If the manometer reading is higher than .075 inches of water column, the system is too restrictive and the installation is unacceptable.
Exhaust direction
All dryers shipped from the factory are set up for rear exhausting. However, on electric dryers, exhausting can be to the right or left side of the cabinet or the bottom of the dryer. On gas dryers, exhausting can be to the right side of the cabinet or the bottom of the dryer. Directional exhausting can be accomplished by installing Exhaust Kit, P/N 131456800, available through your parts distributor. Follow the instructions supplied with the kit.
Although vertical orientation of the exhaust system is acceptable, certain extenuating circumstances could affect the performance of the dryer:
•Only the rigid metal duct work should be used.
•Venting vertically through a roof may expose the exhaust system to down drafts causing an increase in vent restriction.
•Running the exhaust system through an uninsulated area may cause condensation and faster accumulation of lint.
•Compression or crimping of the exhaust system will cause an increase in vent restriction.
•The exhaust system should be inspected and cleaned a minimum of every 18 months with normal usage. The more the dryer is used, the more often you should check the exhaust system and vent hood for proper operation.

Manufactured or mobile home installation
1.Installation MUST conform to current Manufactured Home Construction & Safety Standard, Title 24 CFR, Part
2.Dryer MUST be exhausted outside (outdoors, not beneath the mobile home) using metal ducting that will not support combustion. Metal ducting must be 4 inches (10.16 cm) in diameter with no obstructions. Rigid metal duct is preferred.
3.If dryer is exhausted through the floor and area beneath the mobile home is enclosed, the exhaust system MUST
terminate outside the enclosure with the termination securely fastened to the mobile home structure.
4.Refer to previous sections in this guide for other important exhaust venting system requirements.
5.When installing a gas dryer into a mobile home, a provision must be made for outside make up air. This provision is to be not less than twice the area of the dryer exhaust outlet.
6.Installer MUST anchor this (1) dryer or (2) dryer mounted on pedestal to the floor with approved Mobile Home Installation Kit - P/N 137067200.
