WARNING

VENTILATION

Failure to properly vent this appliance
may cause SERIOUS INJURY, DEATH, or
PROPERTY DAMAGE. The formation of
volatile substances may cause
suffocation, equipment damage,
operational problems and unsatisfactory
cooking performance as a consequence
of improper venting and is not covered
by your warranty.

Ventilation Hoods

Proper venting along with a sufficient quantity of
make-up air is essential for proper oven operation.
A mechanically driven, canopy exhaust hood is
the preferred method of ventilation and must
conform to local codes along with the current

version of NFPA-96 Vapor Removal from Cooking
Equipment (latest edition). The oven hood must

extend 6" (152mm) beyond all sides of the oven.

The distance from the floor to the bottom edge of

the hood should be between 6' (1829mm) and

7' (2134mm).

A ventilation hood that supplies make-up air
down the back vertical wall should be avoided
since air currents can interfere with the oven
flue exits. If such installation is unavoidable, an
additional draft hood, specifically designed to
deflect downdrafts, must be installed.

Ventilation hoods and exhaust systems shall be
permitted to be used to vent appliances installed in
commercial applications.

In accordance with NFPA 54 for the
Commonwealth of Massachusetts only:

Where automatically operated appliances are
vented through a ventilation hood or exhaust
system equipped with a damper or with a power
means of exhaust, provisions shall be made to
allow the  ow of gas to the main burners only
when the damper is open to a position to properly
vent the appliance and when the power means of
exhaust is in operation.

Direct Venting

When necessary, direct venting can be used
in situations where space is limited or to help

offset the high cost of ventilation hoods.

To prevent SERIOUS INJURY, DEATH, or
PROPERTY DAMAGE:

Installation, air adjustment and/or service
work must be in accordance with all local
codes and must be performed by a trained
service technician qualified to work on
gas appliances.

Direct venting should be installed in
compliance with local codes by a certified
professional. In the absence of local codes,
refer to National Fuel Code NFPA 54, ANSI
Z223.1 (latest revision).

Probe Usage:

When the oven probe remains inserted in the probe
bracket, the LED temperature display will indicate
the ambient air temperature inside the oven. To use
the probe for cooking remove it from the bracket
and wipe the full length of the metal probe with
a disposable alcohol pad to clean and sanitize
before using.

Only the tip of the probe senses the internal
product temperature; therefore, it is important the
tip be placed correctly in the product for internal
temperature accuracy. Push the probe tip halfway
into the product, positioning the tip at the center of
the food mass. When inserting the probe into solid
foods, such as meat roast or poultry breasts, push
the probe in from a straight downward position or in
from the side to the center position. If placing into a
semi-liquid or liquid product, the probe cable must
be secured to keep the probe positioned properly.
Do not let the probe tip touch the edges, bottom or
side of a container. Tape the probe cable to the lip or
edge of the container.

NOTICE: When cooking by probe, insert the probe

into the raw product after the oven has
been preheated.

Wait one full minute to allow the probe temperature
to decrease to the internal temperature of the product.
Push the start button to begin the cooking process
after this probe temperature adjustment period. A false
probe reading of the internal product temperature will
cause the oven to default to a holding temperature.

Probe Calibration:

1. To verify product probe calibration, place the
probe in a warm glass of water along with a
quality independent digital thermometer and push
the probe button for two (2) seconds to display the
probes actual temperature. Compare readings.

2. If calibration is required, push the probe button
for eight (8) seconds until the unit beeps twice
and the probe offset is displayed. Adjust the
probe offset to match the difference between the
independent probe temperature and the control
probe temperature by pushing the up or down
arrows to increase or decrease the offset.

3. Repeat steps 1 and 2 to verify the probe calibration
as necessary.

CHEF OPERATING TIPS

The Alto-Shaam convection oven will provide the best results and longest possible
service with the utilization of the following suggestions and guidelines.

NOTICE: Moisture will escape around the doors when baking products with a heavy moisture

content such as chicken, potatoes, etc. This is a normal operating condition.

1. Thoroughly preheat the oven for approximately

20 minutes before use.

2. As a general rule, the cooking temperature can

be set lower than the temperature used in a
conventional oven. Cooking time may also be
shorter. It is suggested the first batch of each
product prepared be monitored closely to check
for variances.

3. Maintain a record of the temperatures, times, and

load capacities established for products cooked on a
regular basis since they will be the same or similar
for succeeding loads.

4. When practical, start cooking the lowest

temperature products first and gradually work up
to products with a higher cooking temperature.

5. If the cooking temperature setting for the

previous product is more than 10°F (5°C to 6°C)
higher than the temperature needed for the next
load, use the FAN COOL DOWN feature to
decrease the oven temperature before setting the
oven to a lower temperature.

6. Work as quickly as possible when loading the oven

to prevent heat loss.

7. When the audible signal indicates the time has

expired, remove the food product from the oven as
quickly as possible to avoid overcooking.

8. Pans should be centered between side racks and

each shelf should be loaded evenly to allow proper
air circulation within the oven compartment.

9. To ensure even cooking when baking, weigh or

measure the product in each pan.

10. When cooking six pans of product, start from the

top of the oven and use side rack positions 2, 4, 6,
8, 10, and 12.

11. Do not overload the oven. A maximum 6 sheet pan

capacity is suggested for most items such as cakes,
cookies, rolls, etc. A maximum of 12 sheet pans
may be used for items such as fish sticks, chicken
nuggets, and hamburgers. It will be necessary to
adjust cooking times accordingly. Refer to
product/pan capacities indicated in this manual.

12. To obtain an evenly baked product, muffin pans

should be placed in the oven with the short side of
each pan facing the front of the oven.

13. When rethermalizing frozen casseroles, preheat

the oven 100°F (38°C) over the suggested
temperature to compensate for the introduction of
a large quantity of frozen product into the oven
compartment. Reset the thermostat to the correct
cooking temperature after the oven is loaded.

14. Use a pan extender or 2" (51mm) deep, 18" x 26",

pan for batter-type products that weigh more than
8 lbs (3 to 4 kg), i.e. pineapple upside-down cake.

15. To avoid obstructing airflow that would result

in uneven cooking results, never place anything
directly on the bottom of the oven cavity.

CARE AND CLEANING

Protecting Stainless Steel Surfaces

Cleaning Agents

NOTICE

WARNING

To prevent serious personal injury, death,
or property damage:

The appliance must be cleaned thoroughly
to avoid deposits of grease and or food
residue inside the appliance that may
catch fire. If fat deposits and/or food waste
inside the appliance ignite, shut down
the appliance immediately and keep the
appliance door closed to extinguish the
fire. If further extinguishing is required,
disconnect the appliance from the main
power and use a fire extinguisher (do not
use water to extinguish a grease fire!).
Failure to clean the appliance properly
invalidates the warranty and relieves
Alto-Shaam of all liability.

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 le 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 per day. Always thoroughly
rinse surfaces a er using a cleaning agent and wipe
standing water as quickly as possible a er rinsing.

Use non-abrasive cleaning products designed for
use on stainless steel surfaces. Cleaning agents must
be chloride-free compounds and must not contain
quaternary salts. Never use hydrochloric acid (muriatic
acid) on stainless steel surfaces. Failure to observe
this precaution will void the warranty. Always use
the proper cleaning agent at the manufacturer's
recommended strength. Contact your local cleaning
supplier for productrecommendations.

Cleaning Materials

Cleaning can usually be accomplished with the
proper cleaning agent and a so , clean cloth. When
more aggressive methods are needed, use a non­abrasive scouring pad on dif cult 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. Failure to observe this precaution will void
the warranty.

polished stainless steel, clean the exterior of the
cabinet with a cleaner recommended for stainless steel
surfaces. Spray the cleaning agent on a clean cloth and
wipe with the grain of the stainless steel.

Wipe control panel, door vents and door handles,
thoroughly since these areas harbor food debris.

Clean exterior glass surfaces with a commercial
window cleaner.

Do not use abrasive cleaning compounds

3. Wipe the interior metal surfaces of the oven with a
paper towel to remove any remaining food debris.

4. Clean interior with a damp cloth or sponge and any
good commercial detergent at the recommended
strength.

5. For baked-on food deposits, use a non-caustic and
non-toxic commercial oven cleaner appropriate
for the interior oven surface of your oven. Follow
the product manufacturer's instructions carefully
for the use of this product. Any commercial
oven cleaner must be approved for use on food
contact areas. Remove soil with the use of a plastic
scouringpad.
