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.

1.13 GAS TYPE AND PRESSURE
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
Always remember to reflect the
person only.
conversion on the oven's nameplate.

1.14 GAS CONNECTION
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 QuickDisconnect Devices for Gas Fuels, ANSI Z21.41; or in
Canada, Quick Disconnect Devices for Use with Gas
Fuels, CAN1-6.9.

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.

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.

1.15 LEAK TESTING
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.

1.16 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.

1.17 GAS EXHAUST
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
c o m p l e t e d i n a c c o r d a n c e w i t h t h e A N S I / N F PA 9 6 - 1 9 8 7 ,
S t a n d a r d f o r Ve n t i l a t i o n C o n t r o l a n d F i r e P r o t e c t i o n o f
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.

1.19 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.

the manifold pressure according to specifications presented
in the Pressure Table in this manual. The valve requires no
adjustment; however, if adjustment is desired, a qualified
technician only should follow the instructions shown below.
A. Turn power and gas supply OFF.
B. Remove protective cap from outlet gas/manifold gas
tap. Unscrew, connect pressure gauge.

1.20.4 IGNITION & BURNER CHECK
After the installation is complete the oven needs to 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

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 unauthor ized
cleaning agents may discolor or har m the inter ior 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, par ticular ly 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 par ts of the hinge.

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.

damage and request an inspection. Mail a written
confirmation of the time, date, and the person called.
7. Save any packages and packing material for further
inspection by the carrier.
8. Promptly file a written claim with the carrier and
