Gas Requirements

WARNING

To reduce the risk of fire or explosion, DO NOT CON-
NECT THE GAS LINE TO THE TUMBLE DRYER IF
THE GAS SERVICE IS NOT THE SAME AS THAT
SPECIFIED ON THE TUMBLE DRYER SERIAL
PLATE! It will first be necessary to convert the gas
burner orifice and gas valve. Appropriate conversion
kits are available.

WARNING

To reduce the risk of gas leaks, fire or explosion, use
a new flexible stainless steel connector.

IMPORTANT: Any product revisions or conversions
must be made by the Manufacturer’s Authorized Deal-
ers, Distributors or local service personnel.

IMPORTANT: The tumble dryer must be isolated from
the gas supply piping system by closing its individual
manual shut-off valve during any pressure testing of
the gas supply piping system at test pressure equal to
or less than 0.5 psig [3.45 kPa, 34.5 mbar].

NOTE: For gas valves with a manual shut-off switch on
the gas valve, the shut-off switch does not protect the
valve from this pressure test. Use the individual man-
ual shut-off valve from the gas supply piping system to
protect the gas valve.

IMPORTANT: The tumble dryer and its manually oper-
ated appliance gas valve must be disconnected from
the gas supply piping system during any pressure test-
ing of that system at test pressures in excess of 0.5
psig [3.45 kPa, 34.5 mbar].

IMPORTANT: The installation must comply with local
codes or, in the absence of local codes:
• with the latest edition of the “National Fuel Gas

Code,” ANSI Z223.1/NFPA 54 in the U.S.A.

• with CAN/CSA-B149.1 Natural Gas and Propane In-

stallation Code in Canada

• In Australia and New Zealand , installation must

comply with the Gas Installations Standard AS/NZS
5601 Part 1: General Installations.

Obtain specific gas service pipe size from the gas supplier. Refer
to

Table 5

and

Table 6

for general pipe size.

The following must be furnished and installed by the customer
for the gas service line to each tumble dryer. Refer to

Figure 22

• Sediment traps
• Shut-off valves
• Supply pressure taps

It is important that equal pressure be maintained at all tumble
dryer gas connections. This can be done by installing a 1 inch
[25.4 mm] pipe gas loop to maintain equal pressure at all gas
connections. Refer to

Figure 23

WARNING

To reduce the risk of fire or explosion, if the tumble
dryer is to be connected to Liquefied Petroleum
(L.P.) gas, a vent to the outdoors must be provided
in the room where the tumble dryer is installed.
