INSTALLATION, OPERATION AND CARE OF

ABC7 SERIES COMBI

SAVE THESE INSTRUCTIONS

GENERAL

Vulcan combination ovens are designed and assembled in the USA with quality workmanship and material. Proper installation, usage and maintenance will result in many years of satisfactory performance. It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions provided.

The ABC Combi is unique in many ways but most notable is the controls: Temperature, Time, and Humidity. The most essential, yet consistent control capability for a combi.

INSTALLATION

Before installing, verify that the electrical and/or gas supply agrees with the speciﬁ cations on the data plate located on the lower front corner of the right side panel. If the supply and equipment requirements do not agree, do not proceed with the installation. Contact your dealer or Vulcan-Hart immediately.

UNPACKING

Each oven is inspected before leaving the factory. The transportation company assumes full responsibility for safe delivery upon acceptance of the shipment. Immediately after delivery, unpack and check for shipping damage. If the oven is damaged, save the packing material and contact the carrier immediately. There is a ﬁ fteen-day limitation on ﬁ ling freight damage claims with the freight company. Freight damage is not covered under warranty.

INSTALLATION CODES AND STANDARDS

In the United States, the Vulcan Combi Oven must be installed in accordance with:

1. State and local codes.

LOCATION

Allow space for operating the oven. Do not obstruct the ventilation ports above the oven. To provide ventilation access, allow 1" clearance on the left side of the oven and 3" clearance on the right and 4" at the rear. A suitable amount of space (18" minimum) should be provided on the right side of the machine for service. Ensure a level ﬂ oor is available for operation.

DOOR OPENING

The oven is delivered with the door hinged on the left and cannot be reconﬁ gured.

STACKING KITS

Stacking kits are available to allow ovens to stack, one on top of the other. Assembly Instructions are included with the kit.

LEVELING

Use a spirit level on a rack in the oven to make sure the oven is level, both front-to-back and side-to-side. Adjustment of the leveling feet on the bottom of the legs can be made by turning the feet in or out to level the oven. After the drain is connected, check for level by pouring water onto the ﬂ oor of the oven cavity. All water should drain through the drain opening. Adjust leveling if necessary.

HANDLING

Make sure that the lifting device used has a lifting capacity suitable for the weight

to be lifted and that it has been well maintained.

Perform the handling operations using a lifting device that is rated 20% higher than

the weight of the combi.

Do not stand or walk under the unit when lifting or handling it. Failure to observe

these instructions could cause serious injury.

Follow the instructions for lifting the combi included in the stand or stacking kit ordered with the unit.

WATER REQUIREMENTS

As with all steam related products, water ﬁ ltration and regular ﬁ lter replacements coupled with routine deliming are required. Your local Vulcan Service ofﬁ ce can recommend a water treatment system to meet the needs of your local water conditions. Contact your local Vulcan Service representative for water treatment offerings.

WATER QUALITY STATEMENT

The fact that a water supply is potable is no guarantee that it is suitable for steam generation. Proper water quality can improve the taste of the food prepared in the oven, reduce scale build-up or corrosion, and extend equipment life. Local water conditions vary from one location to another and can change throughout the year. The recommended water treatment for effective and efﬁ cient use of this equipment will vary depending on the local water conditions. Your water supply must be within the general guidelines outlined in the chart below at all times during use of this machine or service issues not covered under warranty may result.

Water hardness should be treated by removing the impurities (water softener with carbon block or dechlorinator and/or in-line water treatment). Low water hardness may also require a water treatment system to reduce potential corrosion. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming and reduce corrosion of metallic surfaces.

Daily washing and rinsing of the cavity is required. In some cases it may be needed more than once a day to prevent compounding of contaminants deposited inside cavity even with acceptable ﬁ ltration. Failure to wash and rinse down the cavity daily could result in damage of the oven cavity and interior parts. A Reverse Osmosis water treatment system can be installed to eliminate chlorides or other contaminates from the water if needed.

NOTE: Failure to properly maintain water quality or preventative procedures for water can lead to issues not covered under warranty.

WATER SUPPLY GENERAL GUIDELINES*

Supply Pressure (dynamic ﬂ ow) 30-60 psig Hardness less than 3 grains (17.1 ppm = 1 grain of hardness) Silica less than 13 ppm Chloramines** zero Chlorides** less than 30 ppm*** Total Chlorine**** zero PH range 7-8 Un-Dissolved Solids less than 5 microns

* Testing of water is always done AFTER water ﬁ lter or water treatment used. Water quality does change with usage and should be checked after idle times to see if the condition worsens.

** A carbon block ﬁ lter system should always be used to remove Chlorine and Chloramine. If a water softener is used, a carbon block is still required. Check with your local water treatment specialist for proper sizing and replacement intervals for the carbon block cartridge.

*** If the Chlorides exceed 30 ppm and the oven is used more than 8 hours during the day in steam or combination mode the cavity will require rinsing every 8 hours. Failure to do so will result in corrosion and rusting of the oven cavity and interior parts. A Reverse Osmosis water treatment system can be installed to eliminate chlorides from the water and reduce the hardness. Preventative washing and rinsing may be needed more than once a day to prevent compounding of contaminants inside cavity.

**** Total Chlorine of 4.0 ppm is the max limit for the building water supply. A carbon block ﬁ lter must still be used to remove all Chlorine and Chloramines from the water. Failure to do so will result in corrosion and rust in the cooking cavity which is not covered under warranty.

WATER CONDITIONING

It is important to furnish the combi oven with treated water to reduce scale formation. Scale formation will reduce steam output, cause premature component failure, and shorten equipment life. Most water supplies contain scale producing minerals such as Calcium and Magnesium. As steam is generated, the minerals are deposited into the oven cavity.

This may cause several problems:

1. Reduced heat transfer efﬁ ciency.

2. Premature heating element failures.

3. Deposits inside the cavity that can lead to deterioration of the cavity and glass. These problems are common to any manufacturer's steamer regardless of design, but they can all be

minimized by furnishing the combi oven with treated water and/or performing routine deliming and ﬁ lter maintenance.

The desired water properties can best be achieved by using a properly maintained water treatment system. Strainers or ﬁ lters will not remove minerals from the water.

Steamers that operate over a long period of time without the beneﬁ t of a water treatment system develope a heavy scale build up. These systems should be cleaned before using.

PLUMBING CONNECTIONS

Plumbing connections must comply with applicable sanitary, safety and plumbing codes. NOTE: Failure to properly connect the water lines will result in equipment failure that is not covered under

warranty.

WATER SUPPLY CONNECTIONS

There are two water connections for the combi. Treated water connection supplies steam creation and spray hose water. Untreated water is only used for drain water tempering. Both connections must have water supplied to them. If only treated water is available then make both connections with treated water. Do not supply untreated water to treated connection as it will void warranty.

Connect the treated cold water supply line, min of 3/8" ID, to the ¾" garden hose inlet on the rear of the Combi Oven. Connect the untreated cold water supply line to the ¾" garden hose, also on the rear of the Combi Oven for drain water tempering. All water that enters into the oven cavity needs to be treated. Tempering water is allowable to be untreated.

A water ﬁ lter system is required for the water supply line going to the treated water inlet of your Combi Oven. Follow the recommendations for use and installation instructions shipped with the water ﬁ lter. If a water ﬁ lter is not installed, the Combi Oven warranty is limited.

NOTE: Failure to properly connect the water lines will result in equipment failure that is not covered under warranty.

– 7 –

FILTER SYSTEM

In addition to water conditioning for the control of solids, you must have a carbon block ﬁ lter installed and maintained. Carbon block ﬁ lters remove the chlorine and chloramines disinfectants from the water. Chlorine/chloramines will erode the oven cavity, rack guides, racks, and internal components, which is not covered under warranty. Check with your local water treatment specialist for proper sizing and replacement intervals for the carbon block cartridge.

Water feed lines to the oven must be ﬂ ushed before ﬁ nal connection. Particles in the water could clog tubing and components that supply water for steam production and drain cooling. If the water supply is not free of sediment or cloudy after several minutes of ﬂ ushing, a sediment ﬁ lter must be installed before use.

If you have purchased a water ﬁ lter system from Vulcan-Hart, please follow the instructions provided with the ﬁ lter system. At the time of installation you must register your Combi Oven at www.vulcanhart.com/ ﬁ lterreg or use the reply card supplied with your unit. You will need to register your Combi Oven at each ﬁ lter change to insure your standard and extended warranty is maintained.

Filter purchase invoices and maintenance records must be provided with warranty claims.

DRAIN CONNECTION

In order to avoid any back pressure in the oven, do not connect solidly to any drain.

The 1" NPT threaded ﬁ tting at the rear of the combi must be extended a minimum of 12" (305 mm) - maximum of 72" (1829 mm) away from combi base, to an open air gap type drain. Do not reduce the drain piping throughout its length. Provide a suitable ﬂ oor sink with a minimum depth of 12" (305 mm). The ﬂ oor sink is NOT to be directly under the combi. The drain should slope down away from the combi ¼" for every foot of drain pipe length. The drain pipe should be either iron or copper. DO NOT use PVC pipe; PVC pipe may lose its rigidity or glue may fail.

In order to avoid any back pressure in the oven, do not connect solidly to any drain connection.

GAS SUPPLY CONNECTIONS

Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.

A ¾" NPT minimum inside diameter gas supply line is required. If quick disconnect devices are used, make sure it is sized properly for data plate BTU/hr. rating.

Gas Input 3/4" NPT Natural 5" - 14" W.C.

MINIMUM RATE

Propane 11" - 14" W.C.

Codes require that a manual gas shutoff valve be installed in the gas line ahead of the combi oven. The gas line must be capable of delivering gas to the combi oven without excessive pressure drop at the minimum rate speciﬁ ed on the rating plate.

Inadequate gas supply could result in burner noise and poor burner performance. The proper sizing and installation of the gas connection is important for the machine to operate within

its design speciﬁ cations. In some installations, the gas supply may not be sufﬁ cient enough to allow all the gas equipment to operate properly at peak loads; or when other equipment with a high BTU/hr. input requirement is operating. The connection to the machine becomes even more important in this type of location. Flexible gas connectors with quick disconnect or swivel ﬁ ttings (when used) and gas connectors beyond the length necessary will reduce the BTU/hr. ﬂ ow capacity to the machine.

NOTE: Do not use corrugated stainless steel tubing for commercial gas equipment supply connections.

– 8 –

NOTE: A straight gas connection is the ideal condition for the rated BTU/hr. ﬂ ow capacity of the connector. If a straight connection is not possible and a ﬂ exible gas connector is used, do not twist, kink or excessively ﬂ ex the connector beyond a U-shape. Flexing the gas connector as described will restrict gas ﬂ ow or may damage the connector.

COMBI WALL COMBI WALL

INCORRECT INSTALLATION CORRECT INSTALLATION

Changing a ﬂ exible gas connector may raise the BTU/hr. ﬂ ow capacity enough to allow the machine to operate within its design speciﬁ cations. (i.e. Removing the quick disconnect ﬁ tting, installing a shorter gas connector or installing a larger diameter gas connector.)

An alternative may be to move the equipment to a different gas supply location in the kitchen. (i.e. Closer to the main supply into the kitchen or away from other equipment with high BTU/hr. input requirements.)

The combi oven is equipped with a factory preset pressure regulator. Natural gas pressure regulators are preset for 5.0" W.C. (1.2 kPa). Propane gas pressure regulators are preset for 10.0" W.C. (2.46 kPa). No further adjustment should be required. Check gas pressures with a manometer at time of installation to verify that they agree with the pressures speciﬁ ed.

Conversion Kit - GASKIT-ABC – Propane & altitude kit (2,000-10,000 ft.) are available and are to be ﬁ eld installed as needed.

Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution. Do not use an open ﬂ ame. After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

* Breaker rating is based on electrical standard 125% increase over actual amps used.

TESTING THE GAS SUPPLY SYSTEM

When gas supply pressure exceeds

/2 psig (3.45 kPa), the oven and its individual shutoff valve must be

disconnected from the gas supply piping system. When gas supply pressure is

/2 psig (3.45 kPa) or less, the oven should be isolated from the gas supply

system by closing its individual manual shutoff valve.

FLUE GAS EXHAUST

The ﬂ ue is shipped loose and must be installed prior to operation. Failure to install will cause service issues and will void warranty.

DO NOT obstruct the ﬂ ow of ﬂ ue gases from the ﬂ ue located on the top of the combi oven. It is recommended that the ﬂ ue gases be vented to the outside of the building through a ventilation system installed by qualiﬁ ed personnel. Information on the construction and installation of ventilating hoods may be obtained from Vapor Removal from Cooking Equipment, NFPA-96 (latest edition) available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

The output temperature of the exhaust fumes reach 480°F.

ELECTRICAL CONNECTION

Appliances equipped with a ﬂ exible electric supply cord are provided with a three- prong grounding plug. It is imperative that this plug be connected into a properly grounded threeprong receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove the grounding prong from this plug.

Electrical and grounding connections must be in accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22.2, as applicable.

Disconnect electrical power supply and follow lockout / tagout procedures.

The wiring diagram is located on the inside surface of the right side panel as you face the oven. Use copper wire rated for at least 194°F (90°C) for the connection.

Do not drill a hole in the back panel for electrical connection. Use the strain relief locations

provided. This will allow proper access to components for service. To make the electrical connections, remove the right side protective panel. Insert the power supply cable

through the strain relief at the rear of the unit. Once the optimal cable length is established for the connections to the terminal board, clamp the cable using the strain relief. Connect the cables with the terminal board as indicated on the wiring diagram. The wires on the terminal board must be clamped ﬁ rmly.

Gas Model Electrical Connection

Not recommended for ground-fault circuit-interrupter (GFCI) 125-volt, single-phase, 15- and 20-ampere receptacle. Electronic burner ignition systems are prone to nuisance tripping and possible ignition failure.

GROUNDING

The oven must be properly grounded. Connect the ground conductor to the terminal block in the position indicated on the terminal block label.

motor rotation. The fan will rotate in the proper direction.

VENT HOOD

Local codes may require the oven to be located under an exhaust hood. Information on the construction and installation of ventilating hoods may be obtained from Vapor Removal from Cooking Equipment, NFPA Standard No. 96 (latest edition).

BEFORE FIRST USE

Calibration of the humidity measurement system must be performed prior to ﬁ rst use. Refer to the service instructions on how to perform this step prior to ﬁ rst use. Altitude and gas supply affect humidity measurement system so calibration is required before ﬁ rst use.

Before using the oven for the ﬁ rst time, it must be "burned in" to release any odors that might result from heating the new surfaces in the oven. Remove any packaging material and instructions from inside and outside of the unit as the surfaces will get hot. Operate the oven at maximum thermostat setting for 45 minutes.

OFF/ON

The “I” side of the switch is On and the “O” is Off. When the unit switch is turned on ,for both gas and electric models, the

unit powers up and displays the last temperature setting. The unit will begin heating and fan operation immediately.

If there is no recall settings possible (due to a power disconnect), the temperature will default to “---” which deactivates heating, fan and water injection, but all displays are lit. Time will default to “--:--” and humidity will default to “---”. When the temperature knob is adjusted, the unit operates based on parameter settings for temperature, time ,and humidity. If temperature display is “---”, there is still functionality in the timer knob as a timer.

Door lights will remain on when the temperature display is “---”. The door lights are off when the door is open – and on when the door is closed.

When the off/on switch is turned off, the temperature display blinks “CLn” for 3 seconds as a reminder to clean the unit. The time display shows “good”, and the humidity display shows “bye”. After 3 seconds all displays will be blank.

TEMPERATURE

Turning the temperature knob to the right increases temperature set point. Turning the temperature knob to the left decreases the temperature until it reaches lowest temperature. One more turn to the left displays standby mode as “---”.

To set a temperature, turn the temperature knob past 2 indents to a desired temperature and stop. Heating begins based on this new set temperature.

The actual oven cavity temperature is shown by turning the temperature dial 1 indent to the right or left when a set temperature is displayed. The actual temperature is shown for 3 seconds, and then goes back to displaying set temperature.
