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 CSA-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 line pressure must be maintained at 
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 (tumblers, water heaters, space 
heaters, furnace, etc.). An in-line pressure regulator 
may be required if the line pressure exceeds 8 water 
column inches (2.0 kPa) with all gas appliances 
running.
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 (3.23 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:
T30 – M4707P3
T45 – M4880P3
CE GASES refers to Installing CE Gas Drying 
Tumblers 
sections, the above data does not apply to 
the CE.
WARNING
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.
