Gas Requirements - ALLIANCE CA050L Installation Operation & Maintenance

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.
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 or 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)
