The dryer is provided with a 1/2” N.P.T. inlet pipe connection located in the upper rear of the dryer. The
minimum pipe size (supply line) to the dryer is 1/2” pipe. For ease in servicing, the gas supply line of each
dryer must have its own shutoff valve.
IMPORTANT:
The gas supply line to each dryer
must be
a minimum of 1/2-inch.
DO NOT
REDUCE THIS PIPE SIZE REQUIREMENT.
The size of the main gas supply line (header) will vary depending on the distance this line travels from the
gas meter or, in the case of L.P. gas, the supply tank, other gas-operated appliances on the same line, etc.
Specific information regarding supply line size
should be
determined by the gas supplier.
NOTE:
Undersized gas supply piping can create a low or inconsistent pressure, which will result
in erratic operation of the burner ignition system.
