The dryer is provided with two (2) 1-1/4” N.P.T. inlet pipe connections extending out of the top of the burner
boxes. The minimum pipe size (supply line) to the dryer is 1-1/2” N.P.T. For ease of servicing, the gas
supply line to 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 L.P. gas, the supply tank, other gas-operated appliances on the same 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.
