Gas Requirements
IMPORTANT: Any product revisions or
conversions must be made by the Manufacturer’s
Authorized Dealers, Distributors, or local service
personnel.
IMPORTANT: 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, 34.5 mbar).
IMPORTANT: The tumbler 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 psi (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 CAN1-B149.1 or Natural Gas and
Propane Installation Code in Canada,
● and Australian Gas Association/Australian
L.P. Gas Association requirements in
Australia.
Obtain specific gas service pipe size from the gas
supplier. Refer to Table 6 for general pipe size.
The following must be furnished and installed by the
customer for the gas service line to each tumbler.
Refer to Figure 12.
● Sediment traps
● Shut-off valves
● Supply pressure taps
It is important that equal pressure be maintained at all
tumbler gas connections. This can best be done by
installing a one inch (25 mm) pipe gas loop. Refer to
Figure 13.
NATURAL GAS service must be supplied at
7 ± 1.5 inch water column pressure (17.4 ± 4 mbar,
1.74 ± 0.37 kPa). An in-line pressure regulator may be
required on Natural Gas models if the line pressure
exceeds 8 water column inches (2.0 kPa) pressure with
all gas appliances firing.
LIQUID PETROLEUM GAS (L.P.) service must be
supplied at 11 ± 0.3 water column inches
(27 ± 1 mbar, 2.74 ± 0.07 kPa) with all gas appliances
running (tumblers, water heaters, space heaters,
furnace, etc.).
For converting Non-CE models from Natural Gas to
L.P. Gas:
25 Pound – M4699P3
30 Pound – M4703P3
T30 – M4707P3
35 Pound – M4711P3
CE GASES refer to Installing CE Gas Drying
Tumblers section, the above data does not apply to the
CE.
To reduce the risk of fire or explosion, DO
NOT CONNECT THE GAS LINE TO THE
TUMBLER IF THE GAS SERVICE IS NOT
THE SAME AS THAT SPECIFIED ON THE
TUMBLER 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 fire or explosion, if the
tumbler is to be connected to Liquefied
Petroleum (L.P.) gas, a vent to the outdoors
must be provided in the room where the
tumbler is installed.
