Gas Requirements - Alliance Laundry Systems LES33A Instrucciones De Instalación

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, 1,000 Btu/ft
be supplied at 6.5 ± 1.5 inch water column pressure.
For proper operation at altitudes above 2,500 feet (760
m) the natural gas valve spud orifice size must be
reduced to ensure complete combustion. See table at
right.
L.P. (Propane) Gas, 2,500 Btu/ft
service must be supplied at 10 ± 1.5 inch water column
pressure.
NOTE: DO NOT connect the dryer to L.P.
(Propane) Gas Service without converting the gas
valve. An LPK1 Sales Accessory (L.P. [Propane]
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 1/2 psi (3.45 kPa). (See
illustration on page 10.)
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
1/2 psi (3.45 kPa)
NOTE: When connecting to a gas line, an
equipment shutoff valve must be installed within 6'
(1.8 m) of the dryer. An 1/8" N.P.T. pipe plug must
be installed as shown. See illustration.

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 LP
(propane) 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.
