3. Piping and Connections
ALL components and materials must conform to National Gas Code specifications, or in CANADA, the
Canadian Installation Codes (for General Installation and Gas Plumbing). 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" 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 1" 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 if other gas-operated appliances are 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.
