American Dryer Corp MLG32PD3 installation manual

The dryer is provided with a 3/4” N.P.T. inlet pipe connection at the upper right hand corner (when viewed from the rear) of each dryer. It is recommended that a gas shutoff valve be provided to the gas supply line of each dryer for ease of servicing.

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 liquid propane [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 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 a 3/4” pipe loop be installed in the supply line serving 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 water column (W.C.) - 29.9 mb - pressure. (Refer to the illustration below 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.

An 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 gas and L.P. gas must be used.
