do not damage the pipe threads when removing
the cap.
3. Connect to gas supply pipe.
NOTE: When connecting to a gas line, an
equipment shut-off valve must be installed within
6 feet (1.8 m) of the dryer. An 1/8 in. NPT pipe plug
must be installed as shown for checking inlet
pressure. Refer to
Figure 11
.
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 pressures in excess of 1/2 psi (3.45 kPa).

) service must be supplied at 10 ± 1.5 inch
water column pressure.
For proper operation at altitudes above 3000 feet
(915 m) the L.P. gas valve spud orifice size must be
reduced to ensure complete combustion. Refer to
Table 2
.
NOTE: DO NOT connect the dryer to L.P. Gas
Service without converting the gas valve. Install
L.P. Gas Conversion Kit 649P3, available at extra
