2. Remove the shipping cap from the gas connection at the rear
of the dryer. Make sure you 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 in accordance with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 and the Natural
Gas and Propane Installation Code, CSA B149.1
must be installed within 1.8 m [6 feet] of the dryer.
An 1/8 in. NPT pipe plug must be installed as shown
for checking inlet pressure. Refer to Figure 9 .

des
2. 1/8 in. NPT Pipe Plug
3. Equipment Shut-Off Valve
4. Black Iron Pipe:
Shorter than 6.1 m [20 ft.] – Use 9.5 mm [3/8 in.] pipe.
Longer than 6.1 m [20 ft.] – Use 12.7 mm [1/2 in.] pipe.
5. 3/8 in. NPT Gas Connection
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 3.45 kPa [1/2 psi]. Refer to Check
Heat Source.
NOTE: DO NOT connect the dryer to L.P. Gas Service
without converting the gas valve. Install L.P. Gas Con-
version Kit 458P3, available at extra cost.
L.P. (Liquefied Petroleum) Gas, 93.1 MJ/m
ice must be supplied at 10 ± 1.5 inch water column pressure.
For proper operation at altitudes above 1070 m [3500 feet] the
L.P. gas valve spud orifice size must be reduced to ensure com-
plete combustion. Refer to Table 5 .
