Gas Requirements - Amana LED20AW-PLED20AW Installation Instructions Manual

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
_[nstallation Code.
Natural Gas service must be
supplied at 6.5 + 1.5 inch water
column pressure.
17or proper operatio n 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. Gas 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
lest 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
[/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" (3.1 ram)
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 metal connector.
• Use pipe joint compound insoluble in LP Gas 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.
