Gas Requirements
Gas Dryers
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/CGA-B149,
National
Gas Installation
Code.
Natural Gas, 1000 Btu/ft 3 (37.3 MJ/m 3) service must
be supplied
at 6.5 + 1.5 inch water column pressure.
For proper operation
at altitudes
above 2500 feet
(760 m) the natural gas valve spud orifice size must be
reduced to ensure complete
combustion.
Refer to
Table 1.
L.P. (Liquefied
Petroleum)
Gas, 2500 Btu/ft 3
(93.1 MJ/m 3) service must be supplied at 10 + 1.5 inch
water column pressure.
NOTE: DO NOT connect
the dryer to L.P. Gas
Service without
converting
the gas valve. An LPK1
Sales Accessory
(L.P. Gas Conversion
Kit 649P3)
must be installed.
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 0.5 psi (3.45 kPa).
The dryer must be isolated from the gas supply piping
system by closing the equipment
shut-off valve during
any pressure testing of the gas supply piping system at
test pressures
equal to or less than 0.5 psi (3.45 kPa).
NOTE:
When
connecting
to a gas line, an
equipment
shut-off valve must be installed
within
6 feet (1.8 m) of the dryel. An 0.125 inch NPT pipe
plug must be installed
as shown. Refer to Figure 18.

WARNING
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.
(Liquified
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.
