INSTALLATION REQUIREMENTS  
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.  
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.  
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.  
We recommend checking the level of the oven  
periodically to make certain the floor has not  
shifted or the oven moved.  
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

GAS SUPPLY & INSTALLATION  
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.  
GAS REQUIREMENTS  
GAS CONNECTION  
The gas inlet is located at the back of the oven.  
Code requires the installation of a manual gas  
shutoff valve to be installed in the gas line ahead  
of the oven. This oven is also equipped with  
fixed burner orifices determined by the elevation  
specified as the initial installation location.  
In the U.S.A., installation must conform to local  
codes or, in the absence of local codes, with the  
current edition of the National Fuel Gas Code,  
NFPA-54 and ANSI Z223.1-1980 (latest edition).  
In Canada, installation must be in accordance  
with local codes, CAN/CGA-B149.1, Installation  
for Natural Gas Burning Appliances and  
Equipment (latest edition) or CAN/CGA-B149.2  
Installation for Propane Burning Appliances  
and Equipment (latest edition).  
The oven is furnished with a regulator integral  
to the operation of the gas solenoid valve  
and may not require an additional external  
regulator. To ensure safe and proper operation,  
the gas pressure regulator installed in the oven  
is required for use with both natural gas and  
propane. If the connected pressure exceeds  
14.0" W.C. (3.48 kPa), a step-down regulator  
is required. A step-down regulator is not the  
responsibility of the manufacturer.  
The inlet supply line must be properly sized  
to accommodate all individual appliances  
simultaneously used on the same line but  
must never be smaller than 3/4" NPT.

consequence of improper venting.  
Any damage sustained by a failure  
to properly vent this oven are not  
covered under 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).  
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.  
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.  
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 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).

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.  
1. Thoroughly preheat the oven for approximately  
9. To assure even cooking when baking, weigh or  
20 minutes before use.  
measure the product in each pan.  
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.  
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.  
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.  
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.  
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.  
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.  
6. Work as quickly as possible when loading the  
oven to prevent heat loss.  
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.  
7. When the audible signal indicates the time has  
expired, remove the food product from the oven  
as quickly as possible to avoid overcooking.  
15. To avoid obstructing airflow that would result  
in uneven cooking results, never place anything  
directly on the bottom of the oven cavity.  
8. Pans should be centered between side racks and  
each shelf should be loaded evenly to allow proper  
air circulation within the oven compartment.

CARE AND CLEANING  
CLEANING AND PREVENTATIVE MAINTENANCE  
PROTECTING STAINLESS STEEL SURFACES  
CLEANING AGENTS  
It is important to guard against corrosion  
in the care of stainless steel  
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.  
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.  
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.  
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.  
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  
BRUSHES, METAL SCOURING  
PADS OR SCRAPERS.  
MN-28664 • Rev 2 (06/13) • ASC-4G Gas Convection Oven - Manual Control • 17  
 
CARE AND CLEANING  
The oven is fabricated with an easy to clean porcelain  
enamel interior or an optional stainless steel interior.  
DO NOT USE ABRASIVE CLEANING COMPOUNDS.  
Completely avoid the use of abrasive cleaning  
compounds, chloride-based cleaners, or cleaners  
containing quaternary salts. To protect metal  
finish on stainless steel, never use hydrochloric  
acid (muriatic acid).  
NOTE: Always allow the oven to cool before  
cleaning. If the oven is hot, allow the  
interior surfaces to become cool to the  
touch by opening the oven doors and  
engaging the cool-down function.  
DANGER  
DISCONNECT UNIT FROM  
POWER SOURCE BEFORE  
CLEANING OR SERVICING.  
CLEAN THE OVEN ON A DAILY BASIS  
1. After the oven has cooled, remove all detachable  
items such as wire shelves, side racks, and drip  
pan. Clean these items separately.  
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.  
2. Remove any food scraps from shelves, shelf  
supports, and blower fan wheel. Convection  
baffle openings must be kept clear of food  
scraps and grease.  
3. Wipe the interior metal surfaces of the oven  
with a paper towel to remove any remaining  
food debris.  
Wipe control panel, door vents and door handles,  
thoroughly since these areas harbor food debris.  
4. Clean interior with a damp cloth or sponge  
and any good commercial detergent at the  
recommended strength.  
Clean exterior glass surfaces with a commercial  
window cleaner.  
DO NOT USE ABRASIVE CLEANING COMPOUNDS  
MOTOR CARE  
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.  
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  
into the rear of the motor case. This is a general  
operating feature when proper clearances have  
been allowed.  
AT THE END OF THE DAY, UTILIZE THE COOL-  
DOWN MODE AND OPEN THE OVEN DOORS.  
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.  
DANGER  
AT NO TIME SHOULD THE INTERIOR  
OR EXTERIOR BE STEAM CLEANED,  
HOSED DOWN, OR FLOODED WITH  
WATER OR LIQUID SOLUTION OF  
ANY KIND. DO NOT USE WATER JET  
TO CLEAN.  
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.  
SEVERE DAMAGE OR  
ELECTRICAL HAZARD  
COULD RESULT.  
WARRANTY BECOMES VOID IF  
APPLIANCE IS FLOODED  
Always follow appropriate state or local health  
(hygiene) regulations regarding all applicable  
cleaning and sanitation requirements for food  
service equipment.

TRANSPORTATION DAMAGE and CLAIMS  
All Alto-Shaam equipment is sold F.O.B. shipping point, and when accepted by the carrier, such shipments  
become the property of the consignee.  
Should damage occur in shipment, it is a matter between the carrier and the consignee. In such cases,  
the carrier is assumed to be responsible for the safe delivery of the merchandise, unless negligence can be  
established on the part of the shipper.  
1. Make an immediate inspection while the equipment is still in the truck or immediately after it is moved to the receiving area.  
Do not wait until after the material is moved to a storage area.  
2. Do not sign a delivery receipt or a freight bill until you have made a proper count and inspection of all merchandise received.  
3. Note all damage to packages directly on the carrier’s delivery receipt.  
4. Make certain the driver signs this receipt. If he refuses to sign, make a notation of this refusal on the receipt.  
5. If the driver refuses to allow inspection, write the following on the delivery receipt:  
Driver refuses to allow inspection of containers for visible damage.  
6. Telephone the carrier’s office immediately upon finding 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 attach copies of all supporting paperwork.  
We will continue our policy of assisting our customers in collecting claims which have been properly filed and actively pursued.  
We cannot, however, file any damage claims for you, assume the responsibility of any claims, or accept deductions in payment  
for such claims.

occurs first.  
The labor warranty period is one (1) year from the date of installation or fifteen (15) months from the shipping date, whichever occurs first.  
Alto-Shaam will bear normal labor charges performed during standard business hours, excluding overtime, holiday rates or any
