22 American Dryer Corp. 113231-4
Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch
(19.05 mm) pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure
regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches
(29.9 mb) of water column (W.C.) pressure.
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).
WARNING: NEVER TEST FOR LEAKS WITH A FLAME!!!
