EXHAUST
EXHAUST DUCT LENGTH INFORMATION
• The MAXIMUM ALLOWABLE length of the exhaust
system depends upon the type of duct, number of
turns, the type of exhaust hood (wall cap) and all
conditions noted below. The maximum allowable length
for both rigid and flexible metal is shown in the table
below. More than three 90° turns are not
recommended.
HOOD OR WALL CAP
• Terminate in a manner to prevent back drafts or entry
of birds or other wildlife.
• Termination should present minimal resistance to
the exhaust airflow and should require little or no
maintenance to prevent clogging.
• Never install a screen over the exhaust duct.
• Wall caps must be installed at least 12
″ above
ground level or any other obstruction with the
opening pointed down.
• If roof vents or louvered plenums are used, they must
be equivalent to a 4 ″ dampered wall cap in regard to
resistance to airflow, prevention of back drafts and
maintenance required to prevent clogging.
TURNS OTHER THAN 90°
• One turn of 45° or less may be ignored.
• Two 45° turns should be treated as one 90°.

Installation Instructions
GAS CONNECTION INFORMATION
CAUTION:
Do not attempt to alter gas orifice or adjust burner air
shutter. Natural gas input may vary in some areas from
700 to 1200 B.T.U. per cubic foot. If the gas orifice or
burner air shutter is incorrectly adjusted, serious
personal injury and/or fire hazard can occur. Your local
gas company will know the qualities of the gas in your
area. Contact your local servicing dealer if burner
adjustment or orifice changes are necessary.
Do not use an open flame for leak testing. Serious
personal injury and/or a fire hazard can result if an open
flame is used to test for gas leaks. Use a soap and water
solution to test all gas line fittings.
Do not install the Laundry Center to an L.P. gas supply
without installing conversion kit. All Laundry Centers
are shipped with a pressure regulator and natural gas
orifice. Using a natural gas orifice with an L.P. gas supply
can result in personal injury, clothes damage and/or a
fire hazard. Have a qualified gas technician install a
conversion kit in the Laundry Center before use.
• Installation must meet American National Standard,
National Fuel Gas Code ANSI Z 223 1—1988 and local
codes and ordinances.
• The gas supply line should be a 1/2 ″ pipe. A 1/2″ to
3/8
″ reducer must be used to connect the dryer to
the supply line.
• The gas supply line must have a shut-off valve
preferably within six feet of the dryer.
• A 1/8 ″ NPT plugged tapping, accessible for test gauge
connection, must be installed immediately upstream
of the gas supply connection.
