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
and Gas Installations Standard AS/NZS 5601
Part 1: General Installations in Australia and
New Zealand
Obtain specific gas service pipe size from the gas
supplier. Refer to Table 7 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 10.

It is important that equal pressure be maintained at all
tumble dryer gas connections. This can be done by
installing a one inch (25 mm) pipe gas loop. Refer to
NATURAL GAS recommended line pressure is 6.5
water column inches (1.62 kPa), with no less than 5
water column inches (1.24 kPa) and no more than 10.5
water column inches (2.61 kPa), with all gas
appliances running (tumble dryers, water heaters,
space heaters, furnace, etc.). An in-line pressure
regulator may be required if the line pressure exceeds
10.5 water column inches (2.61 kPa) with all gas
appliances running.
LIQUID PETROLEUM GAS (L.P.) line pressure must
LIQUID PETROLEUM GAS (L.P.) line pressure must
be maintained at 11 water column inches (2.74 kPa),
with no less than 10 water column inches (2.49 kPa)
and no more than 13 water column inches (3.23kPa),
with all gas appliances running (tumble dryers, water
heaters, space heaters, furnace, etc.).

WARNING
The tumbler and its individual shut-off
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).
The tumbler must be isolated from the
The tumbler 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).

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.
