L.P. (Liquefied Petroleum) Gas, 93.1 MJ/m
3
(2500 Btu/ft
3
) service 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 complete combustion. Refer to
Table 3.
NOTE: Models not factory equipped for L.P.: DO
NOT connect the dryer to L.P. Gas Service without
converting the gas valve. Install L.P. Gas
Conversion Kit 458P3, available at extra cost.
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.
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 installed as shown for checking inlet
pressure. Refer to Figure 9.
3. Connect to gas supply pipe.
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).
Refer to Step 9 (Check Heat Source).
