Gas Supply; Venting Requirements - Whirlpool 3RAWZ481G Installation Instructions Manual

Gas supply

WARNING
Explosion Hazard
Connect this dryer to a regulated gas
supply. Supply pressure must be in
accordance with the Technical
Specification (see last page).
Use a new flexible gas supply line.
If L.P gas is used, have the L.P. gas
checked by a qualified person before
installing the dryer.
Failure to do so can result in death,
explosion, fire, or burns.
Observe all governing codes and
ordinances.
Gas requirements:
Check that dryer is equipped with the
correct burner for the particular type of gas
supply. Burner information will be found on
the model/serial rating plate in the door
well of the dryer. If this information does
not agree with the type of gas available,
see your dealer.
Natural Gas:
This dryer is factory adjusted for use with
natural gas (G20), and no further
adjustment should be required at
installation.
L.P. Gas:
This dryer is also certified for use with L.P
(propane or butane) gases with
appropriate conversion. No attempt shall
be made to convert the appliance from the
gas specified on the model/serial rating
plate for use with a different gas without
consulting the serving gas supplier.
Conversion must be done by a competent
service technician. Gas conversion kit, part
number 279918, is available for purchase
from your dealer. Full instructions are
supplied with the kit.
Supply line requirements:
Provide a rigid gas supply line to the dryer
location. It should be minimum 12.5 mm
(1/2 inch) ID. When acceptable to the gas
supplier and local codes,
10 mm (3/8-inch) ID rigid supply line may
be used for lengths under 6.1 m (20 feet).
Pipe-joint compounds resistant to the
action of L.P gas must be used.

Gas connection to the dryer itself should
be made by means of a flexible gas hose
suitable for the appliance and gas
category. It should be minimum 10 mm
(3/8") ID. A means of restraint should be
used between the appliance and the wall
to prevent straining of the rigid gas supply
when the appliance is moved. An
appropriate length of chain and a wall
hook is recommended.

Check for leaks as directed by local or
national regulations. A pressure
measurement tapping is provided on the
gas valve within the dryer, accessible after
removal of the lower front panel.
The dryer must be disconnected from the
gas supply piping system during any
pressure testing of that system.

Venting requirements

WARNING
Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to follow these instructions
can result in death or fire.
WARNING:
To reduce the risk of fire,
this dryer must be exhausted outdoors.
10.2 cm (4 in.) heavy metal exhaust vent
and clamps must be used.
• The dryer exhaust must not be connected
into any gas vent, chimney, wall, ceiling,
or a concealed space of a building.
• Do not use an exhaust hood with a
magnetic latch.
• Do not install flexible metal vent in
enclosed walls, ceilings or floors.
• Use clamps to seal all joints. Exhaust
vent must not be connected or secured
with screws or other fastening devices
which extend into the interior of the duct.

• The design of the flue system should
ensure that any condensate formed when
operating from cold, is either retained
and subsequently
re-evaporated or discharged. Following
these installation instructions should
adequately meet this requirement.
