For proper operation at altitudes above 2000 ft. (610 m) the natrual
gas valve spud orifice size must be reduced to ensure complete
combustion.
DO NOT connect the dryer to L.P. Gas Service without converting the
gas valve. A No. 458P3 L.P. Gas Conversion Kit must be installed by
the Manufacturer’s Authorized Dealers, Distributors, or local service
personnel.
L.P. gas service must be supplied at 10 ± 1.5 inch water column
pressure.

If local codes allow the use of flexible tubing, connect the dryer to gas
line with new metal flexible tubing (use design American Gas
Association certified connector) to the 3/8 inch NPT (National Pipe
Thread) gas connection at the rear of the dryer (see below).
NOTE: When connecting to gas line, an equipment shutoff valve must
be installed within 6' (1.8 m) of the dryer. An 1/8 inch N.P.T. pipe plug
must be installed as shown. See illustration below.
