INSTALLATION

SITE INSTALLATION

POSITIONING ON SITE

Lift the oven from the pallet with a fork lift or pallet
lift truck positioned at the front of the oven. For
damage protection, the use of two wooden boards,
placed between the bottom of the oven and the lifting
forks, is strongly recommended. To avoid damage,
position the lift forks to the left of the condenser
and right of the right leg as indicated in the diagram
above.

Stand the oven in a level position. Use the adjustable
feet to overcome an uneven floor and ensure that the
unit is level.

It is strongly recommended that table top models be
mounted on a factory supplied stand or a stand that
is stable, open, and level. Recommended height is

23-inches (584mm).

Adjust the height of floor models for smooth access
of the trolley or cart. When positioning the oven,
observe the minimum space allocation requirements
shown.

To insure proper operation, the installation of this
oven must be completed by qualified technicians in
accordance with the instructions provided in this
manual. Failure to follow the instructions provided
may result in damage to the oven, building, or cause
personal injury to personnel.

technician qualifi ed to work on
gas appliances.

1. A single gas Combitherm oven requires a minimum

of 28 CFM make-up air for natural and propane
gas. Kitchen ventilation must include a provision

for an adequate ow of fresh air for gas combustion

and to prevent a negative-pressure condition. The
bottom of the oven provides air supply access for
gas combustion and must be kept clear at all times.
DO NOT obstruct or restrict ventilation nor the air

ow required to support combustion.

2. DO NOT obstruct the flow of the exhaust flue at

the top rear of the oven. It is especially critical
that gas supply piping and electrical support
cord and/or receptacle be routed away from the
path of the hot combustion fumes.

CAUTION

An adequate ventilation system is required for
commercial cooking equipment. Information may be
obtained by writing to the National Fire Protection

Association, Batterymarch Park, Quincy, MA 02269.
When writing refer to NFPA No. 96.

4. This oven cannot be direct vented.

5. Install the oven under a ventilation hood meeting

all applicable code requirements. Combustion
fumes must be vented in accordance with local,
state, or national codes.

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.

To prevent malfunction or cause
negative back draft, DO NOT obstruct
exhaust fl ues or attach any fl ue
extension that will impede proper
burner operation.

3. Make certain the oven installation maintains adequate

air ventilation to provide cooling for electrical and gas
components. The area around the oven should be clear

of any obstructions which might retard the ow of

cooling air. Failure to observe this caution may result in
damage to the components and will void the warranty.

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 thermal­overload protection device on the
blower motor to trip resulting in
severe damage to the blower motor.

GAS SUPPLY & INSTALLATION

The minimum size requirement for gas piping or a

flexible connector is 3/4 - inch (19mm). For long runs

of gas piping, the pipe diameter must conform to the
tables in the National Fuel Gas Code, ANSI/NFPA
Z223.1.

A listed gas shut-off valve must be installed
upstream of the appliance to shut off the gas
supply during servicing. The shut-off valve should
be accessible with the appliance in the normal
installation position.

If the oven or the oven stand is supplied with
casters, gas connection must be made with a flexible
connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI

Z21.69; or in Canada, Connectors for Movable Gas
Appliances, CAN/CGA-6.16-M87. When using a

flexible connector, a quick disconnect device must
be used to comply with the Standard for Quick-

Disconnect Devices for Gas Fuels, ANSI Z21.41; or in

Canada, Quick Disconnect Devices for Use with Gas

Fuels, CAN1-6.9.

The other end of the cable should be permanently
attached to the rear frame of the oven. The cable
should be of sufficient length so that no strain is ever
placed on the flexible gas connector in the event of
accidental movement of the oven without properly
disconnecting the gas connector. The flexible
connector should be routed to form a downward
“U” loop between the building gas supply and the
permanent attachment at the rear of the oven.

The routing of the flexible connector must not be
made under the oven. Oven temperatures achieved
during operation are too hot for safe operation. Gas
piping should be installed from the point of gas
connection at the bottom, front of the oven to the
back of the oven where the flexible connector may be
safely used. See the illustration for the recommended
placement.

When a quick disconnect device and flexible
connector are used, a restraining device must be
installed to limit the movement of the appliance and
prevent damage to the connector or quick disconnect.
An example of a restraining device would consist
of a 2000 pound test, stainless steel cable, attached
to a structural member of the kitchen wall behind
the oven. The means of attachment should consist
of a quick connect snap so that the oven can be
disconnected when the appliance must be moved
away from the wall.

LEAK TESTING

INSTALLATION

If a pressure leak test above 1/ 2 psi is to be
performed on the building supply gas piping, the
shut-off gas valve and oven inlet gas supply line
must be disconnected from the building supply
piping before conducting the pressure test. Failure
to do so may result in damage to the manual gas
valve, gas components in the oven, or both.

If any gas leak tests are to be conducted at
pressures equal to or below 1/ 2 psi, the manual gas
shut-off valve upstream of the oven must be turned
off before conducting the tests.

Leak testing of the internal oven piping system
was conducted before shipping the oven from the
factory. If additional testing is needed, it should
only be conducted at normal gas supply pressures.
If the testing is performed using combustible gas in
the piping, the leak checking should be done with a
soap solution (bubble checking).

GAS EXHAUST

The use of an electronic combustible gas leak
detector is helpful, however, this type of detector
can be oversensitive. Electronic detectors may
indicate false leaks from other sources which
would not be detected when checking with a liquid
solution to verify a no-hazard gas connection.

When starting the oven after initial installation,
the gas lines must be free of air. It may take up
to 30 minutes to eliminate all air from the lines.
If, after this time there is no pilot, call for factory
assistance.

DANGER

NEVER USE AN OPEN

FLAME TO LEAK TEST.

The oven is not designed for direct connection to a
chimney vent system or for direct connection to a
horizontal exhaust system.

The oven must be installed under a ventilation

hood listed to ANSI/UL 705 (latest edition), and the

installation must be completed in accordance with

the ANSI/NFPA 96-1987, Standard for Ventilation

Control and Fire Protection of Commercial Cooking
Operations.

Oven operators should be instructed with regard
to the hazards of placing any material on top of the

oven that would obstruct the
flow of flue products out the
opening of the flue diverter.
Operators should also be
instructed with regard to the
hazards of hot flue gases and
that any material or items
placed on top of, or in front
of the flue defector could be
damaged or cause a fire hazard.

WATER QUALITY REQUIREMENTS

WATER SUPPLY & INSTALLATION

USE A DRINKING QUALITY, COLD WATER SUPPLY ONLY

Water quality is of critical importance when
installing steam producing equipment of any kind,
particularly high temperature steam producing
equipment. Water that is perfectly safe to drink is
composed of chemical characteristics that directly
affect the metal surfaces of steam producing
equipment. These chemical characteristics differ
greatly from region to region throughout the U.S. and
the world. Varying combinations of pH; alkalinity;

hardness; chlorides; total dissolved solids; and other
chemical characteristics, when subjected to high
temperatures, will cause water to have a tendency to
either scale or corrode.

Alto-Shaam has consulted with people who
understand the properties of water in order to
provide water quality standards that meet the
broadest possible range of acceptable water quality
requirements to help protect your investment.

We strongly urge water testing to ascertain the water
quality on site prior to the installation of any steam
producing equipment. Since water quality is an
important issue, Alto-Shaam is committed to provide
as much information as possible to help protect the
investment made in this equipment.

A CombiGuard™ Water Filtration System can
be purchased as an option for installation on the
Combitherm oven. This filter, when properly
installed, maintained, and combined with the
required levels of steam generating equipment
maintenance, will help lessen the affect water has
on metal surfaces. It will not, however, provide
complete protection against all water damage from
region to region.

Due to the complexity of water chemistry, it
is important to understand that water quality
plays a significant role in the longevity of steam
producing equipment. Water quality and required
maintenance of steam generating equipment is the
direct responsibility of the owner/operator. Damage
incurred as a direct result of poor water quality
and/or surfaces affected by water quality is also the
responsibility of the owner/operator. Damage due
to water quality that does not meet the minimum
standards shown below is not covered under the
Alto-Shaam Combitherm warranty.

Alto-Shaam will continue our efforts to provide
