Supply Pipe
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.
(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.
