3. Connect to gas supply pipe.
NOTE: When connecting to a gas line, an equipment
shut-off valve must be installed within 1.8 m [6 feet]
of the dryer. An 1/8 in. NPT pipe plug must be instal-
led as shown for checking inlet pressure. Refer to

4. Tighten all connections securely. Turn on gas and check all
pipe connections (internal & external) for gas leaks with a
non-corrosive leak detection fluid.
NOTE: The dryer and its appliance main gas valve must
be disconnected from the gas supply piping system
during any pressure testing of that system at test pres-
sures in excess of 50 mbar. Refer to
Check Heat Source .
NOTE: DO NOT connect the dryer to L.P. gas without
consulting the distributor and/or without performing
the proper conversion according to the conversion in-
