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 speci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 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 ve-day limitation on ling freight damage claims with the freight company. Freight damage is

not covered under warranty.

INSTALLATION CODES AND STANDARDS

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 oor is available for operation.

DOOR OPENING

The oven is delivered with the door hinged on the left and cannot be recon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 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 ltration and regular lter replacements coupled with routine

deliming are required. Your local Vulcan Service o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 oerings.

– 6 –

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 eective and e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 de-

chlorinator 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 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 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 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 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 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.

– 7 –

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 e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 lter

maintenance.

The desired water properties can best be achieved by using a properly maintained water treatment system.

Strainers or lters will not remove minerals from the water.

Steamers that operate over a long period of time without the bene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 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 lter. If a

water 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.

– 8 –

FILTER SYSTEM

In addition to water conditioning for the control of solids, you must have a carbon block lter installed

and maintained. Carbon block 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 ushed before 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 ushing, a sediment lter must be installed before use.

If you have purchased a water lter system from Vulcan, please follow the instructions provided with the

lter system. At the time of installation you must register your Combi Oven at www.vulcanhart.com/

lterreg or use the reply card supplied with your unit. You will need to register your Combi Oven at each

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 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 oor sink with a minimum depth of 12" (305 mm).

The 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.

Codes require that a manual gas shuto 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 speci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 specications. In some installations, the gas supply may not be su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 ttings (when used) and gas connectors

beyond the length necessary will reduce the BTU/hr. ow capacity to the machine.

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

MINIMUM RATE

Gas Input 3/4" NPT

Natural 5" - 14" W.C.

Propane 11" - 14" W.C.

– 9 –

NOTE: A straight gas connection is the ideal condition for the rated BTU/hr. ow capacity of the connector.

If a straight connection is not possible and a exible gas connector is used, do not twist, kink or excessively

ex the connector beyond a U-shape. Flexing the gas connector as described will restrict gas ow or may

damage the connector.

Changing a exible gas connector may raise the BTU/hr. ow capacity enough to allow the machine to

operate within its design specications. (i.e. Removing the quick disconnect tting, installing a shorter gas

connector or installing a larger diameter gas connector.)

An alternative may be to move the equipment to a dierent 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 specied.

Conversion Kit - GASKIT-ABC – Propane & altitude kit (2,000-10,000 ft.) are available and are to be 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 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 shuto 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 shuto valve.

FLUE GAS EXHAUST

The 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 ow of ue gases from the ue located on the top of the combi oven. It is recommended

that the ue gases be vented to the outside of the building through a ventilation system installed by

quali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 exible electric supply cord are provided with a three-

prong grounding plug. It is imperative that this plug be connected into a properly grounded three-

prong 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 rmly.

Gas Model Electrical Connection

The spark ignition in this appliance can cause electrical noise that can false trigger the GFCI detection.

Some GFCI’s are more sensitive than others. The use of a higher trip tolerance GFCI will reduce nuisance

tripping. Contact Technical Support for more information.

GROUNDING

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

indicated on the terminal block label.

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 rst use. Refer to the

service instructions on how to perform this step prior to rst use. Altitude and gas supply aect humidity

measurement system so calibration is required before rst use.

Before using the oven for the 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.

STAINLESS STEEL EQUIPMENT CARE AND CLEANING

(Supplied courtesy of NAFEM. For more information, visit their web site at www.nafem.org)

Contrary to popular belief, stainless steels ARE susceptible to

rusting.

Corrosion on metals is everywhere. It is recognized quickly on iron

and steel as unsightly yellow/orange rust. Such metals are called

“active” because they actively corrode in a natural environment when

their atoms combine with oxygen to form rust.

Stainless steels are passive metals because they contain other

metals, like chromium, nickel and manganese that stabilize the

atoms. 400 series stainless steels are called ferritic, contain

chromium, and are magnetic; 300 series stainless steels are called

austenitic, contain chromium and nickel; and 200 series stainless,

also austenitic, contains manganese, nitrogen and carbon. Austenitic

types of stainless are not magnetic, and generally provide greater

resistance to corrosion than ferritic types.

With 12-30 percent chromium, an invisible passive lm covers the

steel’s surface acting as a shield against corrosion. As long as the

lm is intact and not broken or contaminated, the metal is passive

and stain-less. If the passive lm of stainless steel has been broken,

equipment starts to corrode. At its end, it rusts.

Enemies of Stainless Steel

There are three basic things which can break down stainless steel’s

passivity layer and allow corrosion to occur.

1. Mechanical abrasion

2. Deposits and water

3. Chlorides

Mechanical abrasion means those things that will scratch a steel

surface. Steel pads, wire brushes and scrapers are prime examples.

Water comes out of the faucet in varying degrees of hardness.

Depending on what part of the country you live in, you may have hard

or soft water. Hard water may leave spots, and when heated leave

deposits behind that if left to sit, will break down the passive layer and

rust stainless steel. Other deposits from food preparation and service

must be properly removed.

Chlorides are found nearly everywhere. They are in water, food

and table salt. One of the worst chloride perpetrators can come from

household and industrial cleaners.

So what does all this mean? Don’t Despair!

Here are a few steps that can help prevent stainless steel rust.

1. Use the proper tools.

When cleaning stainless steel products, use non-abrasive tools.

Soft cloths and plastic scouring pads will not harm steel’s passive

layer. Stainless steel pads also can be used but the scrubbing

motion must be in the direction of the manufacturers’ polishing

marks.

2. Clean with the polish lines.

Some stainless steel comes with visible polishing lines or “grain.”

When visible lines are present, always scrub in a motion parallel

to the lines. When the grain cannot be seen, play it safe and use

a soft cloth or plastic scouring pad.

3. Use alkaline, alkaline chlorinated or non-chloride

containing cleaners.

While many traditional cleaners are loaded with chlorides, the

industry is providing an ever-increasing choice of non-chloride

cleaners. If you are not sure of chloride content in the cleaner

used, contact your cleaner supplier. If your present cleaner

contains chlorides, ask your supplier if they have an alternative.

Avoid cleaners containing quaternary salts; it also can attack

stainless steel and cause pitting and rusting.

4. Treat your water.

Though this is not always practical, softening hard water can do

much to reduce deposits. There are certain lters that can be

installed to remove distasteful and corrosive elements. To insure

proper water treatment, call a treatment specialist.

5. Keep your food equipment clean.

Use alkaline, alkaline chlorinated or non-chloride cleaners

at recommended strength. Clean frequently to avoid build-

up of hard, stubborn stains. If you boil water in stainless steel

equipment, remember the single most likely cause of damage

is chlorides in the water. Heating cleaners that contain chlorides

have a similar eect.

6. Rinse, rinse, rinse.

If chlorinated cleaners are used, rinse and wipe equipment and

supplies dry immediately. The sooner you wipe o standing water,

especially when it contains cleaning agents, the better. After

wiping equipment down, allow it to air dry; oxygen helps maintain

the stainless steel’s passivity lm.

7. Never use hydrochloric acid (muriatic acid) on stainless

steel.

8. Regularly restore/passivate stainless steel.

Review

1. Stainless steels rust when passivity (lm-shield) breaks down

as a result of scrapes, scratches, deposits and chlorides.

2. Stainless steel rust starts with pits and cracks.

3. Use the proper tools. Do not use steel pads, wire brushes or

scrapers to clean stainless steel.

4. Use non-chlorinated cleaners at recommended concentrations.

Use only chloride free cleaners.

5. Soften your water. Use lters and softeners whenever

possible.

6. Wipe o cleaning agent(s) and standing water as soon as

possible. Prolonged contact causes eventual problems.

To learn more about chloride-stress corrosion and how to prevent it,

contact the equipment manufacturer or cleaning materials supplier.

CLEANING

The Combi oven must be cleaned regularly to maintain performance and to prevent corrosion. Periodic

cleaning is required to the exterior to ensure continued safe, reliable operation. Review the cleaning

instruction provided.

The oven has considerable amounts of stainless steel that will require proper care. Review the section

Stainless Steel Equipment Care and Cleaning for additional information about proper care for stainless steel.

For cleaning and delime procedures, removal of wire rack shelves, side rack guide supports, and the fan

screen guard to clean them separately may be needed based on usage. Food residue deposited on these

items during cooking can build up in hard to clean areas. Cleaning these items separately can extend their

life and lower cleaning needs for the oven cavity.

The oven and its parts are hot. Always allow the oven to cool before cleaning.

Harsh, corrosive, inappropriate chemicals and untreated water can destroy the

protective passivation layer of stainless steel leading to corrosion.

Do not dispose of oil, grease, fat or solid debris down the drain inside the combi cavity.

The chemical eects of water contaminants, salt and/or vinegar or other acidic substances

during cooking could create long-term eects of corrosion in the cooking compartment. At the end of a

cooking cycle with these substances, clean the equipment thoroughly with detergent and rinse well. This

is in addition to daily cleaning/rinsing of the cavity.

NOTE: The liquid detergent for cleaning the cooking compartment must have certain chemical characteristics.

The detergent should have a pH level between 8-12 and be free of chlorine/ammonia and have viscosity

and density levels similar to water.

NOTE: Pot and Pan Detergent used in sinks, or hand dishwashing detergent is NOT recommended.

NOTE: If detergent is questionable for use, we recommend to share the MSDS sheet with a Vulcan

representative for review/approval.

DOOR GASKET

1. Clean the gasket-sealing surface of the oven doors to remove food acids for maximum gasket life.

Do not use any solvents or sharp instruments.

2. Wash with a cloth moistened in a solution of mild detergent and warm water.

3. Rinse with a fresh cloth moistened with warm water to remove all traces of detergent.

4. Wipe dry with a clean cloth.

Never apply food oils or petroleum lubricants directly to the door gasket. Petroleum-based

solvents and lubricants will reduce the gasket life.

Leave Oven Door Open

Leave the oven door slightly open when the oven is not in use. When the oven is idle, never latch the

door and apply pressure to the door gasket. Leaving the gasket under pressure can cause permanent

deformation and reduce the gasket life.
