3. Piping/Connections
ALL components/materials must conform to National Gas Code specifications. It is important that gas
pressure regulators meet applicable pressure requirements and that gas meters be rated for the total amount
of ALL the appliance BTU's being supplied.
The dryer is provided with a 3/4" N.P.T. inlet pipe connection located at the right side of the base of the
dryer. The minimum pipe size (supply line) to the dryer is 3/4" N.P.T. For ease servicing, the gas supply
line of each dryer must have its own shut-off valve.
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. (liquid propane) 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.
