WATER PRESSURE REQUIREMENTS:
MINIMUM 30 PSI (2 BAR)
MAXIMUM 90 PSI (6 BAR)
Flush the water line at the installation site before
connecting the oven to the water supply. A shut-off
valve and approved back-flow preventer must be
installed when connecting the oven to the cold water
intake. The water supply line must be a minimum of
3/4-inch (NPT) (19mm). A hose connector is supplied
for flexible hose connection to the COLD water source.
A water filtration system is recommended if the water
supply is between 7 and 9 grains of hardness. If water
tests over 14 grains of hardness, the installation of a
water softener is strongly recommended.
THE SHUT-OFF VALVE MUST BE IN THE OPEN POSITION
WHEN THE OVEN IS BEING USED.
PIPE SEALING TAPE (TEFLON®) MUST
BE USED AT ALL CONNECTION POINTS.
The use of a pipe sealing compound is not recommended.
The hand shower spray hose is installed adjacent
to the cold water intake connection. A ball valve
is installed on the oven for hose connection to
the COLD water source. Assemble the washer
and the flexible hose on the ball valve and hang the
spray handle on the holder previously installed
on the oven.
The oven must discharge through an indirect waste
pipe by means of an air gap. The drain thread is
1-1/4-inch (32mm) NPT. A union is required. Install
a 1-1/4-inch (32mm) diameter drain line. The drain
line must always be a positive gradient away from

COMBITHERM®GAS INSTALLATION
1.13 GAS TYPE AND PRESSURE
1.14 GAS CONNECTION
1.12 GAS CONNECTION REQUIREMENTS
Installation of this oven must be completed by a qualified installer familiar with the local codes and
regulations governing the installation of commercial gas appliances.
Installation must be in accordance with local codes, and in the absence of local codes, with the National Fuel
Gas Code ANSI Z223.1 (latest edition). In Canada, the appropriate code is the Natural Gas Installation Code,
CAN/CGA-B149.1 or the Propane Installation Code, CAN/CGA-B.
Check the oven nameplate information to determine
if the oven was manufactured for use with natural or
propane gas. Make certain the gas supply matches
the nameplate information.
Check the oven nameplate to determine the gas
manifold pressure for the oven. The minimum
supply pressure to the oven must exceed this value
by at least 1" w.c. It is recommended that the supply
pressure be between 5" w.c. and 14" w.c. for natural
gas, and 11" w.c. and 14" w.c. for propane.
An alternate gas supply inlet may be required
for installation sites with elevations at 3,000
feet (914m) above sea level. Please check
with the factory.
Should conversion to the opposite fuel be desired,
conversion parts must be ordered from the factory.
Conversion must be completed by a qualified service
person only. Always remember to reflect the
conversion on the oven's nameplate.
The minimum size requirement for gas piping or a
flexible connector is 3
/
4- inch (19mm). For long runs
of gas piping, the pipe diameter must conform to the
tables in the National Fuel Gas Code, ANSI/NFPA
Z223.1.
A listed gas shut-off valve must be installed
upstream of the appliance to shut off the gas supply
during servicing. The shut-off valve should be
accessible with the appliance in the normal
installation position.
If the oven or the oven stand is supplied with casters,
gas connection must be made with a flexible
connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI
Z21.69; or in Canada, Connectors for Movable Gas
Appliances, CAN/CGA-6.16-M87. When using a
flexible connector, a quick disconnect device must be
used to comply with the Standard for Quick-
Disconnect Devices for Gas Fuels, ANSI Z21.41; or in
Canada, Quick Disconnect Devices for Use with Gas
Fuels, CAN1-6.9.
When a quick disconnect device and flexible
connector are used, a restraining device must be
installed to limit the movement of the appliance and
prevent damage to the connector or quick disconnect.
An example of a restraining device would consist of
a 2000 pound test, stainless steel cable, attached to a
structural member of the kitchen wall behind the
oven. The means of attachment should consist of a
quick connect snap so that the oven can be
disconnected when the appliance must be moved
away from the wall.
The other end of the cable should be permanently
attached to the rear frame of the oven. The cable
should be of sufficient length so that no strain is ever
placed on the flexible gas connector in the event of
accidental movement of the oven without properly
disconnecting the gas connector. The flexible
connector should be routed to form a downward "U"
loop between the building gas supply and the
permanent attachment at the rear of the oven.
The routing of the flexible connector must not be
made under the oven. Oven temperatures achieved
during operation are too hot for safe operation. Gas
piping should be installed from the point of gas
connection at the bottom, front of the oven to the
back of the oven where the flexible connector may
be safely used. See the illustration for the
recommended placement.
CAUTION
OVERHEATING
DANGER
Gas piping
must never
be installed
to run under
the burner.
COMBITHERM GAS INSTALLATION AND MAINTENANCE MANUAL 6011ML
PG.8
If a pressure leak test above 1/2 psi is to be
performed on the building supply gas piping, the
shut-off gas valve and oven inlet gas supply line
must be disconnected from the building supply
piping before conducting the pressure test. Failure
to do so may result in damage to the manual gas
valve, gas components in the oven, or both.
If any gas leak tests are to be conducted at pressures
equal to or below 1/2 psi, the manual gas shut-off
valve upstream of the oven must be turned off before
conducting the tests.
Leak testing of the internal oven piping system was
conducted before shipping the oven from the factory.
If additional testing is needed, it should only be
conducted at normal gas supply pressures. If the
testing is performed using combustible gas in the
piping, the leak checking should be done with a soap
solution (bubble checking).
The use of an electronic combustible gas leak detector
is helpful, however, this type of detector can be
oversensitive. Electronic detectors may indicate false
leaks from other sources which would not be detected
when checking with a liquid solution to verify a
no-hazard gas connection.
NEVER CHECK FOR LEAKS
USING AN OPEN FLAME.
When starting the oven after initial installation, the
gas lines must be free of air. It may take up to 30
minutes to eliminate all air from the lines. If, after
this time there is no pilot, call for factory assistance.
1.15 LEAK TESTING
1.17 GAS EXHAUST
COMBITHERM®GAS INSTALLATION
The oven is not designed for direct connection to a chimney vent
system or for direct connection to a horizontal exhaust system.
The oven must be installed under a ventilation hood listed to
ANSI/UL 705 (latest edition), and the installation must be
completed in accordance with the ANSI/NFPA 96-1987,
Standard for Ventilation Control and Fire Protection of
Commercial Cooking Operations.
The oven is supplied with a flue diverter which must be installed
on the oven prior to installation. See Assembly Requirements
toward the front of this manual.
Oven operators should be instructed with regard to the
hazards of placing any material on top of the oven that
would obstruct the flow of flue products out the
opening of the flue diverter. Operators should also
be instructed with regard to the hazards of hot flue
gases and that any material or items placed on top of, or in front
of the flue defector could be damaged or cause a fire hazard.
1.16 FUEL INTERLOCK SYSTEM
Local codes may require the fuel supply to the oven be interlocked to the ventilation hood. If that is the case,
a separate, electrically operated gas valve must be installed in the gas line. Valve selection is at the discretion
of the installer, however, the valve must be recognized by the authority which has jurisdiction.
COMBITHERM GAS INSTALLATION AND MAINTENANCE MANUAL 6011ML
PG.9
1.19 GAS FLAME PATTERNS
When starting the oven after initial installation, the gas lines must be free of air. It may take up to 30 minutes
to eliminate all air from the lines. If, after this time there is no pilot, call for factory assistance.
After the installation is complete, the oven must be test fired to
ensure that the system is operating properly. Follow the operating
instructions located in the cooking guide furnished with the oven.
Under most circumstances, initial operation will be the only
installer check necessary.
The flame pattern under both hot and cold conditions should be
stable on all burner ports. There should be no lifting or blowing
after 15 seconds of operation. Gas Combitherm ovens are not
equipped with air shutter adjustment on the burners. If the flame
pattern does not match correct pattern shown, contact the factory
for further directions.
Make certain the electric igniter lights the pilot burner quickly. The
main burner should light within 4 seconds, without problems and
should light smoothly with no harsh noise. When the oven is COLD,
cycle the oven ON and OFF five times to verify proper operation.
Allow the oven to heat for 5 minutes and repeat the process.
Check the flame pattern on the burners. The flames should be blue
in color with little or no yellow in the flame. Some yellow tipping
is normal with propane gas models, however, there should be no
indication any yellow tipping will produce soot on the combustion
chamber walls, pilot, or main burner.

ovens are not equipped with air shutter adjustment on the
burners. If the flame pattern does not match correct pattern
shown, contact the factory for further directions.
Make certain the electric igniter lights the pilot burner
quickly. The main burner should light within 4 seconds,
without problems and should light smoothly with no harsh
noise. When the oven is COLD, cycle the oven ON and OFF
five times to verify proper operation. Allow the oven to
heat for 5 minutes and repeat the process.
Check the flame pattern on the burners. The flames should
be blue in color with little or no yellow in the flame. Some
yellow tipping is normal with propane gas models,
however, there should be no indication any yellow tipping
will produce soot on the combustion chamber walls, pilot,
or main burner.
1.20.5 VERIFY SEQUENCE OF OPERATION
The Gas Combitherm is fitted with an intermittent pilot and a
Honeywell gas valve, which provides automatic pilot ignition and
main burner ignition. The ignition control system will routinely
undergo three ignition trials (for pilot burner ignition) before

2.2 Preventive Maintenance
In addition to the routine cleaning and maintenance procedures, there are several additional steps to be
taken for both sanitation purposes and to keep the oven running at top operating efficiency. These
additional safeguards will help prevent inconvenient down time and costly repairs.
DO NOT DISPOSE OF GREASE, FAT, OR SOLID WASTE DOWN THE OVEN DRAIN. Fats and
solids will eventually coagulate in the drain system, causing blockage.
MAKE CERTAIN THE DRAIN SCREEN IS ALWAYS IN PLACE. REMOVE ANY SOLID WASTE
MATERIAL FROM THE DRAIN SCREEN BEFORE IT ENTERS THE DRAIN SYSTEM. The routine
removal of solids from the drain screen will help prevent blockage.
USE THE AUTHORIZED COMBITHERM OVEN CLEANER ONLY. The use of unauthorized
cleaning agents may discolor or harm the interior surfaces of the oven.
TO PROLONG THE LIFE OF THE DOOR GASKET, REMOVE AND CLEAN THIS ITEM DAILY. The
acids and related compounds found in fat, particularly chicken fat, will weaken the composition
of the gasket unless cleaned on a daily basis.
TO ADDITIONALLY PROTECT GASKET LIFE, ALLOW OVEN DOOR TO REMAIN SLIGHTLY
OPEN AT THE END OF THE PRODUCTION DAY. An open door will relieve the pressure on the
door gasket.
ROUTINELY CLEAN DOOR HINGES. Open oven door to relieve tension. Clean all parts of the hinge.

Monthly Cleaning
Thoroughly clean the fan at
a minimum of once every six months.
This procedure will remove the heavy
build-up of grease which
will accumulate on the oven fan.
2.5.4 FAN CLEANING
A Fan Service Tool is included with each Combitherm shipment. This tool
must be used for both disassembling and reassembling the fan whenever a
thorough cleaning is required.
1. Press the oven power switch to the OFF position.
2. Remove the oven shelves and side rack shelf supports.
3. Loosen the fasteners holding the fan guard door and swing the door to
the fully open position.
4. While holding the fan wheel in place, insert the shaft attachment of the
Fan Service Tool through the hole in the ball-shaped water diffuser and
rotate counter-clockwise to completely remove the diffuser.
5. Loosen the two hexagon socket bolts located on either side of the central
wheel hub with the allen-wrench attachment of the Fan Service Tool.
6. Insert the bolt attachment of the Fan Service Tool into the central wheel
hub and turn clockwise until the wheel is completely disengaged from
the mounting shaft.
7. Place the fan and the ball-shaped water diffuser in the bottom of the
oven compartment. Wearing safety glasses and rubber gloves, spray
these items, the walls of the heat exchanger compartment, the pipes and
the back side of the fan-guard door with Combitherm liquid oven
cleaner and let stand for approximately 5 minutes.
8. Thoroughly rinse all sprayed components with the hand-held hose to remove all detergent residue.
9. Dry the fan mounting shaft. Place the fan wheel on the mounting shaft
and lightly tap into place.
10. Tighten the two hexagon socket bolts located on either side of the central
wheel hub with the allen-wrench attachment of the Fan Service Tool.
11. Screw the ball-shaped water diffuser into the central wheel hub and
firmly tighten by hand.
12. Attach the fan guard door with the four screws and replace the side rack
shelf supports and the oven shelves.

2.6 ROLL-IN CART/FOOD TROLLEY CLEANING (ON EQUIPPED MODELS)
1. Remove food trolley to a cart wash area. Trolleys may be cleaned
using any mild cleaning detergent and warm water.
2. Hand wipe all framing, slides, drip pan, and base. Thoroughly
clean debris from the casters. A spray hose can be used for
easier cart cleaning.
3. Remove detergent solution with warm water.
4. Wipe or spray with a sanitizing solution designed for use on metal
and vinyl food contact surfaces.
5. Allow trolley to air dry.
As an alternative, trolleys can be sprayed with Combitherm
liquid oven cleaner while inside the oven. Allow the trolley to
remain in the oven through the normal cleaning cycle,
followed by steps 2 through 5 above.
2.7 DAILY GASKET CLEANING
It is important to prolong the life of the oven gasket by cleaning this
item on a daily basis. Routine cleaning will help protect the
composition of the gasket from deterioration caused by acidic foods.
After allowing the oven to cool, remove pull-out gasket and wash in
hot, soapy water. Do not place in the dishwasher.
Always replace the gasket before cleaning the
oven interior or operating the oven.
