should be installed in a 10.2 cm (4 inch) diameter
VERTICAL duct system. This will prevent a backdraft
when dryer is not in use, and will keep the exhaust air
in balance within the central exhaust system.

To reduce the risk of gas leaks, fire or
explosion:
• Each 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 a dryer. Before
tightening the connection, purge
remaining air from gas line to each 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.
