3. Piping Connections
ALL
components/materials
must conform
to National Gas Code specifications. 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 1/2" 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 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, in the case of L.P. (liquid 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.
NOTE
: Undersized gas supply piping can create a low or inconsistent pressure which will result in
erratic operation of the burner ignition system.
