WARNING
To reduce the risk of fire or explosion, DO NOT
CONNECT 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
Dealers, 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
manual shut-off valve from the gas supply piping
system to protect the gas valve.
IMPORTANT: The tumble dryer and its manually
operated appliance gas valve must be disconnected
from the gas supply piping system during any
pressure testing 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
Installation 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 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.

NATURAL GAS pressures with all gas appliances running
(tumble dryers, water heaters, space heaters, furnace, etc.):
Maximum gas pressure – 10.5 water column inches
(26.1 mbar, 2.61 kPa)
Recommended gas pressure – 6.5 water column inches
(16.2 mbar, 1.62 kPa)
Minimum gas pressure – 5 water column inches
(12.4 mbar, 1.24 kPa)
An in-line pressure regulator may be required if the line pressure
exceeds 10.5 water column inches (26.1 mbar, 2.61 kPa) with all
gas appliances running.
LIQUID PETROLEUM GAS (L.P.) pressures with all gas
appliances running (tumble dryers, water heaters, space heaters,
furnace, etc.):
Maximum gas pressure – 13 water column inches
(32.3 mbar, 3.23 kPa)
Recommended gas pressure – 11 water column inches
(27.4 mbar, 2.74 kPa)
Minimum gas pressure – 10 water column inches
(24.9 mbar, 2.49 kPa)
