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

 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.
