The Combination mode will prove to be the most versatile and widely used mode
the Combitherm oven has to offer. It will produce the best possible results on the
widest variety of products — all within the shortest period of time. The unique control
function of this mode enables the operator to roast or bake with a combination of
steam and convection heat. In addition to shorter cooking times, this combination of
steam and heat offers less product shrinkage and more moisture retention than obtained
in a standard convection oven.

automatically. There is no need to select moisture levels. Foods do not
dry out. Flavors are retained with no transfer of flavors when mixing
product loads.
Due to the automatic steam adjustment, the
door can be opened at any time during a
cooking operation. Be certain to observe the
safety war ning when opening the oven door.
The Combination mode is particularly efficient
when used for baking, broiling, grilling, stewing,
braising, and roasting.
When using the Combination mode, cooking
temperatures can be reduced 10- to 20-percent
below the temperatures used for conventional
cooking methods.
Cooking time will be reduced approximately
40-percent when cooking at the same temperature
used for convection oven cooking and up to 50- to
60-percent less time when cooking at the same
temperature used for a conventional oven.
Food browning in the Combither m begins
at a cooking temperature of approximately
248°F (120°C).
A higher cooking temperature results in heavier
browning but also results in greater product
weight loss. To achieve additional browning use
the Moisture Vent Key or set Gold-n-Brown into
the product procedure. Gold-n-Brown is
particularly useful for adding color to high moisture
products such as chicken and other poultry items
or for additional browning of full loads and other
moist products.
The Combination mode provides even browning
without the necessity to tur n the pans.
For more even cooking, do not cook in pans
deeper than 4-inches (100mm).

CONVECTION MODE
CHEF OPERATING TIPS
The Convection Mode can be used to roast or bake products needing very
short cooking times or for high moisture products such as muffins, cakes,
and cookies, or for browning the sur face of the product.
The Convection mode works best with foods
containing little moisture or for very moist food
which require a dryer finished product.
For baking, preheat the Combither m at a
temperature of 36°F to 54°F (20°C to 30°C) above
the baking temperature required. Once preheated,
reset the temperature as required.
A higher cooking temperature results in heavier
browning but also results in greater product weight
loss. To achieve additional browning use the
Moisture Vent Key or set the Browning Feature
into the product procedure.
To prevent the sur face of food from excessive
drying, the fan will not engage if the inter nal
oven temperature is above 212°F (100°C)
and the set oven temperature is below
212°F (100°C).

RETHERM MODE CHEF OPERATING TIPS
Since plated meals consist of dissimilar products, there are several important factors
to consider in order to produce the finest results. Product density (compactness),
thickness, quantity of product on each plate, and quantity of plates all relate to the
length of time necessary to reheat. Again, experience is the best method to
determine reheating time. Once the time has been determined and recorded for a
specific meal, the results will be consistent for future reheating times.
HELPFUL HINTS FOR REHEATING ON THE PLATE
• ALL FOOD COMPONENTS ON THE PLATE SHOULD BE OF SIMILAR DENSITIES.
• ALL FOOD COMPONENTS ON THE PLATE SHOULD BE SIMILAR IN THICKNESS.
• ARRANGE ALL FOOD COMPONENTS EVENLY ON THE PLATE.
• AVOID EXCESSIVE OVERLAPPING OF PRODUCT.
• SAUCES MUST BE HEATED AND ADDED TO PRODUCT AFTER REHEATING.
• A MIXED VARIETY OF MEALS CAN BE REHEATED AT THE SAME TIME.
• À LA CARTE RETHERMALIZATION

À la carte rethermalization is designed to take
a single plate from a refrigerated temperature to
serving temperature for immediate service. Plates
are prepared in advance, covered, and refrigerated.
Preheat the Combitherm oven. Remove plate from
refrigeration and place in the oven at 275°F (135°C)
for an uncovered plate or 300°F (150°C) for a
covered plate. Plates with meat components will
take more time than plates containing all vegetable
components. Follow internal temperature
requirements for reheating and allow for override
time. After reheating, remove the plate from the
oven, add any sauces, garnish, and serve. This
process can be repeated as required.

• BANQUET RETHERMALIZATION
Banquet rethermalization is designed for high
volume, full or partial load (multiple plate) reheating.
For maximum efficiency, it is essential that volume
rethermalization be used in conjunction with the
utilization of holding cabinets to keep rethermalized
food at proper temperatures.
Plates are assembled in advance, covered, and
refrigerated or loaded on the roll-in cart and
refrigerated. Preheat the Combitherm oven at
275°F (135°C) for uncovered plates or 300°F (150°C)
for covered plates. Remove plates or the roll-in cart
from refrigeration, load in the oven and set timer as
the plates or roll-in cart from the Combitherm and
roll into the companion holding cabinet. Relocate
the holding cabinet to the banquet service area.
• RETHERMALIZING PREFABRICATED AND
VACUUM-PACKED FROZEN FOODS
For bulk product rethermalization, completely
defrost product bags in walk-in cooler. DO NOT
REMOVE PRODUCT FROM THE BAG. Load
thawed bags in preheated oven and rethermalize in
the Low Temperature Steam mode until the required
internal temperature is reached. Place rethermalized
140° to 165°F (60° to 74°C) until ready for service.
For large volume on-the-plate regeneration,
defrost bags in walk-in cooler. Open bags and plate
per menu requirements in a ( MAXIMUM ) 55°F (13°C)
refrigerated room. Cover plates, place on Alto-Shaam
roll-in cart (trolley), and roll into Combitherm oven
preheated at 275°F (135°C).
Regenerate in the Convection mode for 3 to 5
minutes. Switch to the Retherm mode for an
additional 3 minutes or more if required. Transfer
full trolley to a preheated holding cabinet set at
160°F (71°C) until ready for service. In the case of
meat cooked to rare, set the cabinet at 140°F (60°C).
PLATE COVERS MUST BE USED FOR ON-THE-PLATE REGENERATION.

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.
● D O N O T D I S P O S E O F G R E A S E , FAT, O R S O L I D WA S T E D O W N T H E O V E N D R A I N .
Fats and solids will eventually coagulate in the drain system, causing blockage. Consequently, water
will back-up into the condenser and interior oven compartment, resulting in an oven that is inoperable.
● 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.
● U S E T H E A U T H O R I Z E D C O M B I T H E R M O V E N C L E A N E R O N LY . T h e u s e o f u n a u t h o r i z e d
cleaning agents may discolor or har m the interior sur faces 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.

CLEANING AGENTS
It is important to guard
against corrosion in the care
of stainless steel surfaces.
Harsh, corrosive, or
inappropriate chemicals can
completely destroy the
protective surface layer of
stainless steel. Abrasive pads, steel wool, or metal
implements will abrade surfaces causing damage to
this protective coating and will eventually result in
areas of corrosion. Even water, particularly hard
water that contains high to moderate concentrations
of chloride, will cause oxidation and pitting that
result in rust and corrosion. In addition, many acidic
foods spilled and left to remain on metal surfaces are
contributing factors that will corrode surfaces.
Proper cleaning agents, materials, and methods are
vital to maintaining the appearance and life of this
appliance. Spilled foods should be removed and the
area wiped as soon as possible but at the very least,
a minimum of once a day. Always thoroughly rinse
surfaces after using a cleaning agent and wipe
standing water as quickly as possible after rinsing.
USE AUTHORIZED COMBITHERM
LIQUID OVEN CLEANER ONLY
Cleaning agents must be chloride-free compounds
and must not contain quaternary salts. Never use
hydrochloric acid (muriatic acid) on stainless steel
surfaces. Unauthorized cleaning agents may discolor
or harm interior surfaces of the oven. Read and
understand label and material safety data sheet
before using the oven cleaner.
C L E A N I N G M AT E R I A L S
The cleaning function can
usually be accomplished with
the proper cleaning agent
and a soft, clean cloth. When
more aggressive methods
must be employed, use a
non-abrasive scouring pad on
difficult areas and make
certain to scrub with the
visible grain of surface metal to avoid surface
scratches. Never use wire brushes, metal scouring
pads, or scrapers to remove food residue.
TO PROTECT STAINLESS STEEL
SURFACES, COMPLETELY AVOID
THE USE OF ABRASIVE
CLEANING COMPOUNDS,
CHLORIDE BASED CLEANERS,
OR CLEANERS CONTAINING
QUATERNARY SALTS. NEVER USE
HYDROCHLORIC ACID (MURIATIC
ACID) ON STAINLESS STEEL.
NEVER USE WIRE BRUSHES,
METAL SCOURING PADS OR
SCRAPERS.
SECTION 2 – PREVENTIVE MAINTENANCE • COMBITHERM GAS TECHNICAL SERVICE MANUAL • 51
PREVENTIVE MAINTENANCE
Establishing a routine cleaning and maintenance schedule will help keep the Combitherm oven running at top
operating efficiency and is an absolutely essential part of a comprehensive sanitation program. Good
equipment maintained and kept clean works better and lasts longer. PROTECT YOUR INVESTMENT.

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 gasket in the dishwasher.
Always replace the gasket
before cleaning the oven
