Piping /Connections
ALL components/materials must conform to National Fuel Gas Code ANSI Z223.1-LATEST EDITION
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 BTUs being supplied.
The dryer is provided with a 2-inch N.P.T. inlet pipe connection located at the right side of the base of the
dryer. For ease of 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.
