ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LATEST
EDITION, or in Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Propane Gas) or
LATEST EDITION (for General Installation and Gas Plumbing), as well as local codes and ordinances and
must be done by a qualified professional. 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.

Installer within Australia – refer to AS/NZS5601.1 for guidance on gas supply pipe sizing required for this
appliance installation.

The dryer is provided with a 1/2” N.P.T. inlet pipe connection extending out the back area of the burner box.
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 shutoff 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 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.
