3.Piping Connections

ALL components and materials must conform to National or Canadian 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 1/2" N.P.T. inlet pipe connection located at the upper rear area of the dryer. The minimum pipe size (supply line) to the dryer is 1/2" N.P.T. For ease in 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.
