Auxiliary Alarm
During tumbler installation, you have the option to
connect a separate alarm system to this auxiliary
output. Use of the auxiliary output is not required for
the fire suppression system to operate, but may be used
for additional protection.
NOTE: The auxiliary output is activated during
fire suppression system maintenance test sequence.
Consider this fact prior to your system test every
three months. (Example: If the external system uses
the auxiliary output to call the fire department,
inform the fire department before and after the fire
suppression system maintenance test.)
Gas Requirements
Natural Gas and Liquefied Petroleum
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
3.45 kPa,
34.5 mbar (0.5 psi).
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
3.45 kPa, 34.5 mbar (0.5 psi).
IMPORTANT: The installation must comply with
local codes.
NOTE: This manual is only a supplement. Refer to
installation/operation manual for full instructions.

General Information
This information is to be used when installing gas
tumblers in countries, and/or on gases, different than
the machine’s factory configuration. Tumblers are
supplied from the factory for operation on Natural Gas
8914 kcal/m
3
(1000 Btu/cu ft.) or L.P. Gas 22,250
kcal/m
3
(2500 Btu/cu ft.) in the countries of GB/IE/
PT/ES/IT/GR/LU/CH. To install machines in any
other country or on any other gas requires some level
of modification.
Models are built in two different configurations:
● Regulated Natural Gas – Injector is sized for
Natural Gas, second family, group H (E) at
20 mbar inlet pressure. Regulator/governor is
operational. Gas valve CAN be field-converted to
a non-regulating type.
● Unregulated Liquefied Petroleum (L.P.) Gas –
Injector is sized for L.P. Gas, third family, group
3+ at 28.37 mbar inlet pressure. Regulator/
governor is blocked open. Gas valve CANNOT
be field-converted to a regulating type.
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.

WARNING
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
