Additional Safety Procedures and Precautions

  • To prevent serious injury, death or property damage, your appliance should be inspected and serviced at least every twelve (12) months by an authorized service partner or trained technician.
  • ONLY allow an authorized service partner or trained technician to service or to repair your appliance. Installation or repairs that are not performed by an authorized service partner or trained technician, or the use of non-factory authorized parts will void the warranty and relieve Alto-Shaam of all liability.
  • When working on this appliance, observe precautions in the literature, on tags, on labels attached to or shipped with the appliance and other safety precautions that may apply.
  • If the appliance is installed on casters freedom of movement of the appliance must be restricted so that utility connections (including gas, water, and electricity) cannot be damaged when the unit is moved. If the appliance is moved, make sure that all utility connections are properly disconnected. If the unit is returned to its original position, make sure that any retention devices and utility connections are properly connected.
  • ONLY use the appliance when it is stationary. Mobile oven racks, mobile plate racks, transport trolleys, and appliances on casters can tip over when being moved over an uneven floor or threshold and cause serious injury.
  • ALWAYS apply caster brakes on mobile appliances or accessories when these are not being moved. These items could move or roll on uneven floors and cause property damage or serious injury.
  • Be extremely careful when moving appliances because the food trays may contain hot fluids that may spill, causing serious injury.
  • ALWAYS open the appliance door very slowly. Escaping hot vapors or steam can cause serious injury or death.

  • If your gas appliance is installed under an exhaust hood, the hood must be switched ON when the oven is in use to avoid the build up of combustion gases. Failure to do so may result in serious injury, death or property damage.

  • NEVER place objects near the oven exhaust vents. This area is hot and could be a potential ignition source for a fire.
  • Do not allow objects to block or obstruct the area below the oven base. This may result in fire, damage to the equipment or serious injury.
  • Do not use the attached hand-held hose to spray anything other than the interior of the oven compartment.
  • Do not use the attached hand-held hose on the surface of a hot cooking compartment. The sudden temperature change can damage the oven interior. Allow the oven to cool to a minimum of 150^ (66°C). Failure to observe this precaution can void the warranty.

LIFTING INSTRUCTIONS

Remove banding before lifting. Lift the unit from the front only, never from the side.

Adjust the forks so that they do not damage any of the components under the unit. Note that the control side of the oven is the heaviest portion. Lift the unit just high enough to remove the wooden pallet. Lower the unit as close to the floor as possible and no more than 2" (50mm) above the floor. Secure hoses and dangling cords to avoid tangling or damage. When moving the unit, drive slowly, keep it low to the ground, and use extreme caution.

DEPTH OF FORKS IS CRITICAL FOR UNITS EQUIPPED WITH GREASE COLLECTION TO AVOID DAMAGING THE PUMP

NOTICE: • A minimum distance of 18" (457mm) is strongly recommended for service access. If adequate service clearance is not provided, it will be necessary to disconnect the gas, water, and drain to move the oven with a fork lift for service access. Service charges in connection with inadequate service access is not covered under warranty.

- Do not install a stacked combination directly over a drain. Steam rising up out of the drain will adversely affect operation, hamper cooling air circulation, and may damage electrical and electronic components. Failure to do so will void the warranty. A single oven installed on a stand with solid surface bottom shelf can be positioned over a drain since the solid surface will block the rising steam.

POSITIONING ON SITE - COUNTERTOP

Place the oven on a stable, non-combustible level horizontal surface. 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. The adjustable oven legs should be extended beyond the depth of the positioning ring to allow for leveling after the oven has been placed on the stand.

Each of the legs on the stand and the oven can be adjusted 2" (51mm) up or down.

Level the oven from front-to-back and side-to-side by means of the adjustable legs. Components within the oven condenser tank are sensitive to pitch and can be damaged. The tolerance to level is +/- .125"

If this tolerance range is not achievable, the floor must be repaired to obtain level.

INSTALLATION

GAS SUPPLY & INSTALLATION

WARNING

Alto-Shaam Combitherm Classic CTC20-20G - WARNING - 1

To prevent SERIOUS INJURY, DEATH, or PROPERTY DAMAGE:

Always use proper length pipes to avoid stress on the gas control manifold.

Always use an approved gas pipe sealant at all external threaded connections.

Always remove any tape or compound residue on all external thread connections before installing appliance.

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 or European Standard EN203.

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 or European Standard EN203.

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.

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 run along the side of the exhaust stacks or cross the exhaust stacks. Oven temperatures achieved during operation are too hot for safe operation. Gas piping should be installed from the point of gas connection at the back of the oven and run away from the exhaust stacks where the flexible connector may be safely used. See the illustration for the area to avoid.

GAS LEAK TESTING

If a pressure leak test above 1/2 psi (34,5 mbar) 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 (34,5 mbar), 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).

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 heat, call for factory assistance.

WARNING

Alto-Shaam Combitherm Classic CTC20-20G - WARNING - 1

Never use an open flame or other ignition sources to check for gas leakage. Failure to do so may cause a fire or explosion and result in serious injury or death.

GAS EXHAUST

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

Use a drinking quality, cold water supply only.

WARNING

Significant damage to the appliance cavity, elements, or heat exchanger could result from improper water quality. Failure to meet the water quality requirements and observe this precaution will void the warranty.

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 water filtration system, when properly installed, maintained, and combined with the required levels of steam producing 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 signifi cant 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.

It is the sole responsibility of the owner/operator/purchaser of this equipment to verify that the incoming water supply is comprehensively tested and if required, a means of “water treatment” provided that would meet compliance requirements with the published water quality standards published at right. Non-compliance with these minimum standards will potentially damage this equipment and/or components and VOID the original equipment manufacturer’s warranty. Alto-Shaam recommends using OptiPure® [www.optipurewater.com] products to properly treat your water.

Alto-Shaam will continue our efforts to provide viable solutions to ease the impact of water quality as it relates to heat producing equipment.

CombiHood PLUS™ Ventless Hood Option

Alto-Shaam Combitherm Classic CTC20-20G - CombiHood PLUS™ Ventless Hood Option - 1

natural_image Simple line drawing of a rectangular box with a small protrusion on top (no text or symbols)

The CombiHood PLUS option is factory installed directly on the top of the Alto-Shaam Combitherm CTP or CTC series oven.

  • Using EPA method 202 testing, grease laden vapors emitted by the Combi Ventless hood are 0.58mg / m3 - far less than U.L.'s established standard of 5mg / m3 .
  • Alto-Shaam's factory installed Ventless Hood is placed directly on the top of a Combitherm oven.
  • A high-power fan captures all steam and fumes from the oven cavity into the hood intake and out the back surface exhaust vent, trapping grease as the air moves through the filter system.
  • As fumes and vapors are circulated through the hood, condensed steam drains from a drain at the rear of the hood.
  • An activated charcoal filter cleans the air before venting it out the top of the hood.
  • CombiHood PLUS™ performance is “smart”; engaging the fan during the last minute of the cook mode which provides quiet operation and consumes less power.

Alto-Shaam Combitherm Classic CTC20-20G - CombiHood PLUS™ Ventless Hood Option - 2

text_image FRONT OF HOOD ALIGNS WITH FRONT OF COMBI DOOR

Condensate Drain

A ventless hood condensate drain line to the floor drain must be installed. The 1/2" barbed connection is found at the back of the hood.

The drain line must always be a positive gradient away from the Combitherm oven.

Test the drain for proper drainage and signs of leaking on a monthly basis.

1GreaseFilter

(5017362):

Cleaning frequency should be based on oven usage with a maximum of two weeks between cleaning if the oven is used for non-grease laden products or steam applications only. Grease laden products require cleaning frequency of at least once a week.

Remove the grease filter by pulling it straight out of the housing. Place the filter in the dishwasher or wash separately by placing in hot, soapy water until all grease and particles have been removed. Rinse thoroughly. Allow the filter to air dry before reinstalling.

To replace the grease filter, the air flow arrow on the filter casing should be pointing toward the hood fan.

2CharcoalFilter

(Class I - FI-36620):

The charcoal filter should be inspected once a month for contaminants. Replacement must be made at a minimum of three month intervals — more often if heavy contaminants are visible or if the filter no longer controls odors.

To remove the filter, pull and slide out while holding the bottom housing. When replacing the filter, make certain the air flow arrow(s) point toward the hood fan, and that the filter is replaced in the three-sided metal frame provided with the hood.

NOTICE: A pressure switch is used to detect when the airflow through the charcoal filter is reduced by 25% - indicating a possible blockage. This will generate an E101 error message on the oven control display. The filters will need to cleaned or replaced.

If the filters are not seated properly, an error code E102 will appear on the oven control display at the end of a cooking cycle.
