INSTALLATION
The oven must be mounted on the factory equipped
oven legs or on an optional oven stand. Installation
on a solid or concrete base that in any way restricts
air flow may void the warranty.
All clearances for a proper ventilation air supply
must be maintained to minimize fire hazard. Do
not locate the oven immediately adjacent to any
other heat-generating appliance.
A number of adjustments are associated with
initial installation and start-up. Adjustments
must be conducted by a qualified service
technician. Installation and start-up adjustments
are the responsibility of the dealer or user.
These adjustments include but are not limited to
thermostat calibration, door adjustment, leveling,
and gas pressure verification. The Platinum series
oven burners are factory-adjusted with fixed air
openings and require no field adjustment.
LEVELING
The oven should be
leveled before the gas
supply is connected. Level the oven from
side-to-side and front-to-back with the use of a
spirit level. For ovens installed on a mobile stand,
it is important that the floor surface be level due to
the probability of frequent oven repositioning.
We recommend checking the level of the oven
periodically to make certain the floor has not
shifted or the oven moved.
NOTE: Failure to properly level this oven can
cause improper function as a result
of erratic burner combustion and will
result in the uneven baking of products
consisting of semi-liquid batter.
INSTALLATION REQUIREMENTS
WARNING
Inadequate ventilation, or failure to
ensure an adequate supply of fresh
air will result in a high ambient
temperature at the rear of the
appliance. An excessive ambient
temperature can cause the thermal-
overload protection device on the
blower motor to trip resulting in
severe damage to the blower motor.

INSTALLATION
VENTILATION
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.
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.
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).
DANGER
FAILURE TO VENT THIS APPLIANCE
PROPERLY MAY BE HAZARDOUS TO
THE HEALTH OF THE OPERATOR.
Equipment damage, operational
problems and unsatisfactory baking
performance may also be the
consequence of improper venting.
Any damage sustained by a failure
to properly vent this oven are not
covered under warranty.
DANGER
Installation, air adjustment and/or
service work must be in accordance
with all local codes and must be
performed by a certified service
technician qualified to work on
gas appliances.
Ventilation hoods and exhaust systems shall
be permitted to be used to vent appliances
installed in commercial applications.
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 flow 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.

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.
NOTE: 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.
Do not place anything directly
on the bottom of the oven cavity.
AT THE END OF THE DAY,
UTILIZE THE COOL-DOWN MODE
AND OPEN THE OVEN DOORS.
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 assure 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 two inch (51mm) deep,
18" x 26" pans for batter-type products that weigh
more than 8 pounds (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
MN-28664 • Rev 3 (07/14) • ASC-4G Gas Convection Oven - Manual Control • 17
PROTECTING STAINLESS STEEL SURFACES
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.
CLEANING AGENTS
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.
Always use the proper cleaning agent at the
manufacturer's recommended strength.
Contact your local cleaning supplier for
product recommendations.
CLEANING MATERIALS
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.
CLEANING AND PREVENTATIVE MAINTENANCE
CAUTION
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

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.
6. Wipe door gaskets thoroughly
since these areas harbor food
debris and grease.
7. Rinse surfaces by wiping with
a clean cloth or sponge and clean
warm water.
8. Remove excess water with a sponge
and wipe dry with a clean cloth or air dry.
Leave doors open until interior is completely
dry. Replace side racks and shelves.
Always follow appropriate state or local health
(hygiene) regulations regarding all applicable
cleaning and sanitation requirements for food
service equipment.
EXTERIOR
To help maintain the protective film coating on
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
MOTOR CARE
The convection oven motor contains self-
lubricating, sealed ball bearings and is
generally maintenance-free. During operation,
the interior of the motor is cooled by air flowing
