The dryer is provided with a 1/2” N.P.T. inlet pipe connection located at the upper left rear of the dryer. The
minimum pipe size (supply line) to the dryer is 1/2-inch diameter. 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 (12.7 mm).
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.
IMPORTANT:
The dryer
is not
provided with an internal gas shutoff and an external gas shutoff
must be
provided.
