•Exhausting dryer in hard-to-reach locations can
be done by installing 521P3 Flexible Metal Vent
Kit (available as optional equipment at extra
cost).
•Sufficient make-up air must be supplied to
replace the air exhausted by the dryer. The free
area of any opening for outside air must be at
least 260 cm2(40 in.2).
•Energy efficient buildings with low air
infiltration rates should be equipped with an air
exchanger that can accommodate on demand
make-up air needs in the laundry room. These
devices can be obtained through your building
contractor or building material suppliers.
•Do not draw make-up air from a room containing
a gas fired water heater, a dry cleaner or a hair
salon.

Step 3: (Gas Dryer Only) Connect Gas
Supply Pipe
1. Make certain your dryer is equipped for use with
the type of gas in your laundry room. Dryer is
equipped at the factory for Natural Gas with a
3/8 inch NPT gas connection.
NOTE: The gas service to a gas dryer must
conform with the local codes and ordinances, or in
the absence of local codes and ordinances, with the
latest edition of the National Fuel Gas Code ANSI
Z223.1/NFPA 54 or the CAN/CSA-B149.1, Natural
Gas and Propane Installation Code.
Natural Gas, 37.3 MJ/m3(1000 Btu/ft3) service must
be supplied at minimum 12.7 cm (5.0 inch) water
column pressure to maximum 26.67 cm (10.5 inch)
water column pressure.
For proper operation at altitudes above 760 m
(2500 feet) the natural gas valve spud orifice size must
be reduced to ensure complete combustion. Refer to
Table 2.
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 must be installed within
1.8 m (6 feet) of the dryer. An 1/8 inch NPT pipe
plug must be installed as shown for checking inlet
pressure. Refer to Figure 5.
To reduce the risk of gas leaks, fire or
explosion:
• The dryer must be connected to the type
of gas as shown on nameplate located in
the door recess.
• Use a new flexible stainless steel
connector.
• Use pipe joint compound insoluble in L.P.
(Liquefied Petroleum) Gas, or Teflon tape,
on all pipe threads.
• Purge air and sediment from gas supply
line before connecting it to the dryer.
Before tightening the connection, purge
remaining air from gas line to dryer until
odor of gas is detected. This step is
required to prevent gas valve
contamination.
• Do not use an open flame to check for gas
leaks. Use a non-corrosive leak detection
fluid.
• Any disassembly requiring the use of
tools must be performed by a suitably
qualified service person.
