IMPORTANT:Water column pressure of 4.0 inches for natural gas dryers and 10.5 inches for L.P. gas 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 and L.P. gases must be used.

WARNING:

Test ALL connections for leaks by brushing on a soapy water solution (liquid detergent
also works well). NEVER TEST FOR A GAS LEAK WITH AN OPEN FLAME.
