GAS CONNECTION
All gas supply connections and any pipe joint compound must be resistant to the action of propane
gases. The machine connection is 3/4" external thread. A manual valve (supplied) must be installed
in the gas supply line ahead of the appliance. Make sure piping is clean and free of obstructions, dirt
or pipe joint compound. Recommended gas supply pressures are 7" W.C. (Water Column) for natural
gas and 11" W.C. for propane. The gas line must be capable of delivering gas to the oven without
excessive pressure drop at the rate specified on the rating plate.
The oven is equipped with a factory preset pressure regulator. Natural gas pressure regulators are
preset for 3.5" W.C. for both ovens and steam generators. Propane gas pressure regulators for 10 level
ovens are preset for 10" W.C. for both the oven and steam generator. Propane gas pressure regulators
for 20 level half depth ovens are preset for 8" W.C. for the oven burner and 10" W.C. for the steam
generator. Gas pressure must be checked for correct operating pressure at start-up.
Caster equipped ovens must be installed with a connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI-Z21.69 (latest edition) [in Canada, CAN/CGA-6.16,
latest edition] and a quick-disconnect device that complies with the Standard for Quick-Disconnect
Devices for Use with Gas Fuel, ANSI-Z21.41 (latest edition) [in Canada, CAN 1-6.9, latest edition]. A
gas line strain relief must be provided to limit the movement of the oven without depending on the
connector and the quick-disconnect device or its associated piping to limit oven movement. Attach the
strain relief to the rear of the oven at the location provided. If it is necessary to disconnect the restraint
during service or maintenance, first turn off the gas supply. Reconnect the restraint before returning
the oven to its original installed location and turning the gas supply on.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
The convection burner and the steam generator burner are ignited automatically by electric igniters;
there are no pilot lights. See Start-Up Procedure, page 9.
Keep the appliance area free and clear from all combustible substances. Do not obstruct the flow of
combustion and ventilation air. Make sure there is an adequate supply of air in the room to allow for
combustion at the burners and exhaust by the vent hood system.
Testing the Gas Supply Piping System
When test pressures exceed 1/2 psig (3.45 kPa), the oven and its individual shutoff valve must be
disconnected from the gas supply piping system.
When test pressures are 1/2 psig (3.45 kPa) or less, the oven must be isolated from the gas supply piping
system by closing its individual shutoff valve.

Presence of sediment, silica, excess chlorides or other dissolved solids may lead to a recommendation
for alternate form(s) of water treatment. Test the water with the test strip included with the combi oven.
Other factors affecting steam generation are iron content, amount of chloridation and dissolved gases.
A local water treatment specialist should be consulted before installation of steam generating
equipment.
Water Supply Connections (Fig. 2)
A water filter system is recommended for the water supply line going to the treated water inlet of your
oven. Follow the recommendations for use and installation instructions shipped with the water filter.
If a water filter is not installed, the oven warranty may be limited.
Connect treated potable water ( must be cold) to the inlet labeled for treated water to supply the steam
generator tank. Untreated water contains scale producing minerals which, if supplied to the steam
generator, can precipitate onto the surfaces in the steam generator tank. Due to the temperatures in
the tank, the minerals can bake onto the surfaces and components. This can result in early component
failure and reduced product life. Sensors in the steam generator tank use ions in the water to detect
the water level. Do not use distilled (fully demineralized or de-ionized) water as this could provide a
false reading to the sensors. Strainers and filters will NOT remove minerals from the water.
Connect untreated potable water (must be cold) to the inlet labeled for
untreated water to supply the condenser which cools the drain water.
Both external-threaded nylon inlets 3/4" hose bibb (3/4" NSHT, National
Straight Hose Thread) are located at the rear of the oven. The nylon threads
should be treated carefully so the connections do not leak. A manual shutoff
valve should be provided, convenient to the oven, for each water supply line;
both of these valves should be open when the oven is in operation. Water
pressure for both incoming water lines should be between 20 and 60 psig.

Drain Connection
CAUTION: In order to avoid any back pressure in the oven, do not connect solidly to any drain
connection.
The drain connection, 11/2" NPT threaded fitting, is located underneath the oven at the rear. The drain
line must be plumbed to an open gap-type drain. Drain piping must have suitable pitch, have
appropriate support along its length and have no connection to other piping. The material used in the
drain line should be heat resistant to at least 212°F. The open drain should be located between 3 and
5 feet away from the perimeter of the oven to reduce potential damage from moisture-corrosion. The
drain line from the oven must not be combined with any drain line from another device.

NOTE: In the event of a power failure, the door may be opened by pulling the handle firmly towards
you while firmly pressing against the front of the oven with the other hand (avoid hot air contact).
GREASE FILTER
The grease filter in the rear of the oven chamber should be in place when roasting meat items but may
be removed before baking items that do not produce grease-laden vapors. For information on how to
remove the grease filter, refer to Cleaning (page 32).
BUZZER
When either the Cooking Time has elapsed or the final internal Probe Temperature has been reached,
is pressed. If done, the product should be removed, portioned and
the buzzer will sound until
served. The Buzzer can be adjusted two ways: Buzzer loudness can be adjusted by your service
technician. Buzzer frequency can be set in Configuration Mode for the type of control furnished with
your oven (refer to either page 34 or 36).

LOADING THE OVEN
Open the door. Place the product to be cooked in
suitable containers and slide into the racks or place
the containers securely on shelves in the oven.
When loading a 10 level oven with the landing table
(Fig. 6), the bottom frame of the rack should be
secured by the rotary lock. Move the loaded landing
table to the front of the open oven; secure the
landing table to the oven by actuating the locking
clamp (or use your body to hold the landing table
against the oven). Rotate the lock-knob to release
the pan rack and carefully roll the loaded pan rack
into the oven while making sure that the landing
table does not separate from the oven during the
transfer.
NOTE: When the landing table is not in use on the
10 level oven, make sure the rack retainer (delivered
with the oven) is fitted under the fan baffle to
prevent the pan rack from tilting when pans are
being removed.
Fig. 6
When loading a 20 level oven with the trolley (Fig. 7), make sure the handle is locked in the down
position so the rack is held securely to the trolley with its lifting hooks. Carefully move the loaded trolley
completely into the open oven. When the rear frame of the rack is positioned behind the edge of the
retainer, raise the handle to lower the rack-frame to the oven door.
UNLOADING THE OVEN
Allow the door to be slightly-opened for a few seconds to allow hot air and steam to escape. Stand
behind the door while opening.
When unloading a 10 level oven, move the landing
table so the clamp locks the landing table to the
front of the oven (or use your body to hold the
landing table against the oven). Remove the landing
table handles and clamp them to the bottom of the
hot oven pan rack. Carefully roll the hot pan rack
onto the landing table platform while making sure
that the landing table does not separate from the
oven during transfer. Rotate the knob to allow the
rack to move completely to the front of the landing
table; and rotate the knob back to lock the pan rack
in place.
When unloading a 20 level oven, move the trolley
(Fig. 7) into the oven until the "lift-hooks" are inserted
into both sides of the front frame of the rack in the
correct "lift" position. Lower the trolley handle until
it stops; the loaded rack is lifted from its retainer and
held securely to the trolley by the "lift-hooks". The
trolley may now be removed from the oven with the
loaded rack securely held in place.

PROBE
The Probe Temperature defines the final temperature of the product for any cooking phase. The
cooking cycle stops when the product temperature reaches the probe temperature setting. Total
Cooking Time is not known or entered when using the probe.
COOKING WITH THE PROBE
There are two ways to control the oven temperature when using the Probe . . .
1) Setting the Oven Temperature at a constant value. The oven climbs to the set point and the product
cooks at that temperature. The cooking cycle ends when the product reaches the Probe
temperature setting.

USING THE TEMPERATURE PROBE
The Temperature Probe is kept in a metal holder at the top of the oven when not in use. Remove the
probe from its holder; the cable remains permanently connected to the top of the oven. Insert the
pointed end of the probe so its tip is approximately in the middle of the product to be cooked. The probe
cable is long enough to allow the product to be placed on one of the upper racks in the oven. The probe
can be used to define the final temperature for any phase of the cooking process and for any of the three
cooking modes: Convection (Hot Air), Steam or Combi.
• To set the Probe Temperature, press
and use the UP and DOWN arrows to adjust the setting.
The Cooking Time cannot be used when the Probe Temperature is in use.
NOTE: During Operator training to demonstrate use of the probe, place the probe in a container of
water to simulate cooking of actual product.

STEAMING (Steam Mode only)
Steam Mode will not begin if cavity temperature is above 212°F (100°C).
Steam cooking is used for stewing, poaching and gentle cooking of products cooked in water. Steam
flows without pressure into the oven. The fan circulates the steam to all parts of the oven. Allow the
steam generator to preheat for 4 to 5 minutes if starting from cold.
Automatic Steaming can be set up so the buzzer sounds when the Cooking Time has elapsed or when
the product's internal temperature has reached the Probe Temperature set point. If using the Probe

CLEANING
Daily Cleaning
Preheat the oven to 130°F and spray a mild detergent solution that does not contain chlorine on the
inside surfaces of the oven. A Spray Bottle is provided. Allow the detergent solution to react for
15 minutes.
Operate the oven on Steam mode for 15 minutes. Allow the oven to cool; wipe the oven interior with
a sponge and warm water. Dry the oven interior with a clean soft cloth.
DO NOT use abrasive products.
Clean the exterior with a cloth or sponge and non-agressive, non-abrasive products.
Complete Cleaning
WARNING: UNPLUG THE ELECTRICAL POWER CORD.
Remove the Rack (Fig. 8). Remove the Grease Filter (Fig. 8) at the rear of the oven chamber by lifting
up and out. Remove the Fan Baffle (Fig. 9) by lifting up and out. Remove the Rack Retainer (Fig. 9)
normally located under the Grease Filter and Fan Baffle. Wash the removed parts in a sink with warm
soapy water, rinse with clear water and dry with a clean dry cloth.

Complete Cleaning (continued)
The Interior Glass Door (Fig. 10) is independently hinged to allow both sides of the glass doors to be
cleaned. With the oven door open, pull the Interior Glass Door away from the exterior oven door. The
snap-release fasteners should allow the Interior Glass Door to swing free. All four sides of the glass
can be cleaned using a cloth and glass cleaner. Alternatively, clean the glass surfaces with soapy
water, rinse with clear water and dry with a clean cloth. The area between, behind and around the
surfaces of the upper and lower hinges can be cleaned by holding both ends of a moist soapy cleaning
cloth folded in a 3" wide strip and swabbing up and down; rinse and dry with clean wet or dry cloth in
the same manner. When glass is clean, push the Interior Glass Door against the exterior oven door:
The snap-release fasteners should re-fasten the Interior Glass Door to the exterior glass door so it
operates as one door.
Wipe surfaces which touch the Door Gasket with a cloth or sponge and warm soapy water, rinse with
clear water and wipe with a dry cloth. CAUTION: Do not allow the door gasket to come in contact
with food oils, petroleum solvents, lubricants or caustic cleaners.
For 10 level ovens, remove the drip tray (Fig. 10) by removing the two thumbscrews that attach it to
the bottom of the oven. For 20 level ovens, the three segment drip tray may be removed for cleaning.
Save the screws. Wash and rinse the drip tray in a sink with warm soapy water, rinse with clear water
and dry with a clean cloth. To reinstall drip tray: Reverse the removal procedure, align screw holes
and tighten screws.
Clean the Condensate Gutter as necessary using a cloth with warm soapy water. Rinse with a clean
cloth and fresh water and allow to air dry.
Keep the cooking compartment drain (Fig. 10) working freely. After cooking grease producing foods,
operate the oven with the compartment empty for 30 minutes at the end of the day, or slowly pour
1
/2 gallon of warm soapy water down the drain, followed by 1/2 gallon of warm clear water. The drain
grating may be removed for cleaning; replace it in its original position when done.
Leave the door slightly open when the oven is not in use to allow the inside to dry out.
