3.Piping Connections

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 (Liquid Propane [L.P.] 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.

The dryer is provided with two (2) 3/4” N.P.T. inlet pipe connections (one [1] for each basket [tumbler]) at the rear of the dryer. If a separate feed is provided for each basket (tumbler) from the main supply line (header), then a 3/4” line connection is sufficient. However, if the top basket (tumbler) and the bottom basket (tumbler) are connected together, the supply from this connection to the header must be a minimum of 1-inch (2.54 cm) and must not exceed 50 feet (15.24 meters). For typical gas connections, refer to the illustration on page 29. It is recommended that a gas shutoff valve be provided to the gas supply line of each dryer basket (tumbler) for ease in servicing.

The size of the gas supply line (header) will vary, depending on the distance this supply line travels from the gas meter (or in case of L.P. gas, the supply tank), the number of tees, other gas-operated appliances on the supply 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 gas pressure, which will result in erratic operation of the burner ignition system.

Consistent gas pressure is essential at ALL gas connections. It is recommended that 3/4” (19.05 cm) pipe loop be installed in the supply line servicing the bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if natural gas line pressure exceeds 12.0 inches (29.9 mb) of water column (W.C.) pressure. Refer to the illustration on the following page for details.

IMPORTANT: Water column pressure of 3.5 inches (8.7 mb) for natural gas dryers and 10.5 inches (26.1 mb) for L.P. gas is required at the gas valve pressure tap of each dryer for proper and safe operation.

A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply line immediately upstream of each dryer.

IMPORTANT: Pipe joint compounds that resist the action of natural and L.P. gases must be used.

WARNING: Test ALL connections for leaks by brushing on a soapy water solution (liquid detergent works well).

WARNING: NEVER TEST FOR LEAKS WITH A FLAME!!!

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 (L.P. 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.
