Fire Suppression System
Water Requirements
IMPORTANT: Water must be supplied to the fire
suppression system, or the fire suppression system
will not operate as intended.
Connection point to the electric water solenoid valve is
a 19 mm (3/4 inch) hose. The fire suppression system
equipped tumbler must be supplied with a minimum
water pipe size of 12.7 mm (1/2 inch)and be provided
with a minimum of 138 kPa (20 psi) and a maximum
of 827 kPa (120 psi) of pressure at all times. Flowrate
must be no less than, but approximately 57 liter
(15 gallons) per minute.
NOTE: Water pressure under 138 kPa (20 psi) will
cause low flow and water leakage at water solenoid
valve.
IMPORTANT: Temperature of the water supply
must be kept between 4.4° and 48.9°C (40° and
120°F). If water in the supply line or water solenoid
valve freezes, the fire suppression system will not
operate.
IMPORTANT: If temperature sensors inside the
tumbler register a temperature below 4.4°C (40°F),
the fire suppression system control will lock out.
This feature protects against operation of the
tumbler with a possible frozen water supply. Only
when the temperature sensors register a
temperature above 4.4°C (40°F) will the machine
reset for operation.
IMPORTANT: Flexible supply line/coupling must
be used. Solenoid valve failure due to hard
plumbing connections will void the warranty. It is
recommended that a filter or strainer be installed
in the water supply line.
Water Connections
Figure 2
IMPORTANT: Thread hose couplings onto valve
connections finger tight, then turn 1/4 turn with
pliers. Do not cross thread or overtighten
couplings.
IMPORTANT: Replace all hoses every five years.
NOTE: Longer inlet hoses are available (as
optional equipment at extra cost) if the hoses
supplied with the tumbler are not long enough for
installation. Order hoses as follows:
Part No. 20617 Inlet hose 2.44 m (8 feet)
Part No. 20618 Inlet hose 3.05 m (10 feet)
Electrical Requirements
No independent external power source or supply
connection is necessary. Power to operate the 24 Volt
fire suppression system is from the rear junction/
contactor box.
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.
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.
W060
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.

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
or L.P. Gas 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:
●Natural Gas – regulated/governor
●Liquefied Petroleum (L.P.) Gas – not regulated/
no governor
Machines configured for Natural Gas (regulator/
governor) may be converted to L.P. Gas (not regulated/
no governor) with block-open kit, Part No. M400763.
Serial plates are configured for GB/IE/PT/ES/IT/GR/
LU/CH.
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.

Exhaust Requirements
Make-Up Air
IMPORTANT: Do not obstruct the flow of
combustion and ventilation air.
A tumbler is forced air exhausted and requires
provisions for make-up air to replace the air exhausted
by the tumbler.
The required make-up air opening to the outside for
each tumbler is:
928 sq. cm (144 sq. in.) for 50 pound tumbler
models
1258 sq. cm (195 sq. in.) for 75 pound tumbler
models
Make-up air openings with louvers will restrict
airflow. The opening must be increased to compensate
for area taken up by louvers.
If it is necessary to duct make-up air to the tumbler(s),
increase the area of the ductwork by 25% to
compensate for any restriction in air movement.
Venting
Proper sized exhaust ducts are essential for proper
operation. All elbows should be sweep type. Exhaust
ducts must be assembled so the interior surfaces are
smooth to prevent the accumulation of lint.
DO NOT use plastic or thin foil flexible ducts. Use
exhaust ducts made of sheet metal or other
noncombustible material. Use duct tape or pop rivets
on all seams and joints.
Verify that old ducts are thoroughly cleaned out before
installing new tumbler.
NOTE: The ducts must be equivalent in strength
and corrosion resistance to ducts made of
galvanized sheet steel not less than 0.495 mm
(0.0195 inches) thick.
IMPORTANT: For best performance, provide an
individual exhaust duct for each tumbler. Do not
install a hot water heater in a room containing
tumblers. It is better to have the water heater in a
separate room with a separate air inlet.
NOTE: This manual is only a supplement. Refer to
installation/operation manual for full instructions.
A drying tumbler produces combustible
lint. To reduce the risk of fire, the tumbler
must be exhausted to the outdoors.
W057
To reduce the risk of fire and accumulation
of combustible gases, DO NOT exhaust
tumbler air into a window well, gas vent,
chimney or enclosed, unventilated area
such as an attic wall, ceiling, crawl space
under a building, or concealed space of a
building.
