NOTE: A water column test pressure of 3.5 inches (8.7 mb) for natural gas and 10.5 inches (26.1 mb)

for liquid propane (L.P.) dryers is required at the gas valve pressure tap of each dryer for
proper and safe operation.

A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply
line immediately upstream of each dryer.

IMPORTANT: Pipe joint compounds that resist the action of natural gas and L.P. gas must be used.

IMPORTANT: Test ALL connections for leaks by brushing on a soapy water solution (liquid

detergent works well).


IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas supply

piping system during any pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).

NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual

shutoff valve during any pressure test of the gas supply system at test pressures equal to or less
than 1/2 psig (3.5 kPa).


The following items should be checked before attempting to operate the dryer:

1. Read ALLCAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.

2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label.

3. GAS MODELS – check to ensure that the dryer is connected to the type of heat/gas indicated on the

dryer data label.

4. GAS MODELS – the sail switch damper assembly was installed and adjusted at the factory prior to

shipping. However, each sail switch adjustment must be checked to ensure that this important safety
control is functioning.

5. Check bolts, nuts, screws, terminals, and fittings for tightness and security.

6. GAS MODELS – be sure that ALL gas shutoff valves are in the open position.

7. Check that ALL back guard panels and service box covers have been replaced.

8. Check the lint drawer to ensure that it is closed and secured in place.

9. Rotate the basket (tumbler/drum) by hand to be sure it moves freely.

10. Check basket (tumbler) bearing setscrews to ensure that they are ALL tight.

11. Check vent is connected to the dryer and is exhausted to the outdoors.
