DRYER VENTING REQUIREMENTS
1.  Remove red cap from gas pipe on back of dryer.
2.   Connect gas supply to dryer. Use a pipe thread compound 
approved for the type of gas supplied. If flexible metal 
tubing is used, be certain there are no kinks.
If necessary for service, depending on model: 
Open the toe panel by removing the 2

from the bottom of the panel. Then lift up on the panel while 
pulling the bottom of the panel away from the dryer.

The outside end of main vent should have a sweep elbow 
directed downward. 
If main vent travels vertically through the roof, rather than 
through wall, install a 180° sweep elbow on end of vent at least 
2 ft. (610 mm) above surface of roof. 
The opening in wall or roof shall have a diameter 1⁄2" (13 mm) 
larger than vent diameter. Vent should be centered in opening.
Do not install screening over end of vent for best performance.

A main vent can be used for venting a group of dryers. The 
main vent should be sized to remove 5663 l/min. (200 CFM)  
of air per dryer. Large-capacity lint screens of proper design 
may be used in main vent if checked and cleaned frequently. 
The room where the dryers are located should have make-up 
air (air supply) equal to or greater than CFM of all the dryers in 
the room. 
Back-draft dampers are available from your distributor and 
should be installed in the vent of each dryer to keep exhausted 
air from returning into dryers and to keep exhaust in balance 
within main vent. Unobstructed return air openings are required.
Although usually each single-load dryer should have an 
unobstructed outdoor air opening of 24 in.

] per 1,000 Btu [252 kcal]), common make-up 
air openings are also acceptable. Set up common openings so 
the make-up air is distributed equally to all of the dryers. Keep 
in mind that the coverage area must be increased by 33% to 
account for the use of registers or louvers over the openings.  
Also, make-up air openings should not be installed near the 
location where exhaust vents exit the building.
Each vent should enter the main vent at an angle pointing in 
the direction of the airflow. Vents entering from the opposite 
side should be staggered to reduce the exhausted air from 
interfering with the other vents.
The maximum angle of each vent entering the main vent should 
be no more than 30°.
Keep air openings free of dry cleaning fluid fumes. Fumes 
create acids which, when drawn through the dryer heating 
units, can damage dryers and items being dried.
A clean-out cover should be located on the main vent for 
periodic cleaning of the vent system.

3.   Open the shut-off valve in the gas supply line and make sure 
the dryer has its own gas supply opened.
4.   Test all connections by brushing on an approved 
noncorrosive leak-detection solution. Bubbles will show  
a leak. Correct any leaks found.
