GENERAL

INTRODUCTION

Vulcan-Hart Ovens are produced with
quality workmanship and material.
Proper installation, usage, and
maintenance of your oven will result in
many years of satisfactory performance.

This manual is provided to assist
persons responsible for the operation
and maintenance of the oven with a
simple, but comprehensive under­standing of its proper use. We
recommend that you thoroughly read
this entire manual and carefully follow all
of the instructions provided prior to
placing the oven into operation.

As with any piece of food service
equipment, this oven system requires a
minimum of care and maintenance.
Recommended procedures are
contained in this manual and should
become a regular part of the operation
of the unit.

INSTALLATION

Before installing, verify that the electrical
service agrees with the specifications on
the rating plate located on the lower
back corner of the oven. If the supply
and equipment requirements do not
agree, do not proceed with unpacking
and installation. Contact your Vulcan­Hart Customer Service Department
immediately.

UNPACKING:
The oven was inspected before leaving
the factory. The transportation company
assumes full responsibility for safe
delivery upon acceptance of the

shipment. Immediately after unpacking,
check for possible shipping damage to
the oven.

If the oven is found to be damaged,
save the packaging material and
contact the carrier within 15 days of
delivery.

Carefully unpack and place in a work
accessible area as near the installation
position as possible.

1. Open the door and carefully
remove any packaging materials
and the retaining straps that hold
the wire plate racks or tray slides
and tray slide upright side
supports.

2. Peel off vinyl protection film from
oven.

CLEANING:
The oven should be thoroughly cleaned
prior to putting into service.

Use a mild soap and water solution to
clean the interior of the oven. Never
use harsh chemicals or abrasive pads to
clean the oven.

LOCATION:
For efficient oven operation, choose a
location that will provide easy loading
and unloading without interfering with
the final assembly of food orders. The
installation location must allow adequate
clearances for servicing and proper
operation.

VRT Models: If floor mounting, the
unit must be Sealed to the floor w ith
NSF Listed Sealant.

5. Check that the Oven Circulating
Fan(s) are running.

6. Check that the Holding
Temperature Indicator Light is
illuminated.

NOTE:

Each Oven is equipped with cooling
fans. The cooling fans may not operate
when the oven is first turned on. The
cooling fans operate only when the
thermostat, to which they are
connected, requires it.

7. Set the COOKING TIME knob
to 2 hours. The Holding
Temperature Indicator Light will
go out and the Cooking
Temperature Indicator Light will
illuminate.

8. Turn the COOKING TEMP­ ERATURE knob to 250⁰ F.
Check the interior rear of the
oven cavity to determine that the
oven is heating.

9. Turn the COOKING TIME KNOB
to 0 and set the HOLDING
TEMPERATURE knob at 250⁰ F.

10. Check that the Cooking
Temperature Indicator Light has
gone out and the Holding
Temperature Indicator Light has
illuminated.

11. Check the interior rear of the
oven to ensure that the oven is
heating. If all the functions
perform satisfactorily, the oven is
ready for operation.

OPERATING INSTRUCTIONS

1. Turn On/Off Switch to ON
position. On/Off indicator Light

and Holding Temperature Light
will illuminate.

2. Turn Holding Temperature knob
to desired holding temperature.

3. Turn Cooking temperature
knob to desired Cooking
temperature.

4. Set Cooking timer knob(s) to
desired cooking time to include

45 minute preheat time.

5. Push Start Button to activate
oven settings.

After the 45 minute pre-heat period, the
oven will be at the desired temperature
and is ready for use. Keep the door
closed during the preheating cycle.

SHUTDOWN

1. Turn Holding Temperature knob
and Cooking Temperature
knob counter-clockwise until
they stop.

2. Open door slightly to allow
ventilation and cool down period.

Note: This is to allow oven to
properly cool down so
electronic components are not
damaged.

Wait 15 minutes before
turning On/Off Switch to OFF because

the cooling fans need to operate during
the cool-down period.

Page 6

VCH & VRT SERIES OVENS F-38055 (11-09)

3. Turn On/Off Switch to OFF
position.

EXTENDED SHUTDOWN

time.

1. Perform the SHUTDOWN
procedure.

2. Unplug the oven.

3. Thoroughly clean the oven
according to the cleaning
procedures in this manual.

4. Leave the door(s) sli ghtly open
to allow ventilation and preservation
of the gasket(s).

CLEANING

WARNING:
Always UNPLUG ELECTRICAL
POWER SUPPLY before cleaning.

Avoid splashing water into upper
areas of the oven to prevent damage
to electrical components or
connections.

Never spray the unit with a hose.
Never use harsh chemicals or

abrasive pads to clean the oven.

DAILY:

1. Unplug electrical power supply.

2. Allow oven to go through cool­ down period before cleaning.

3. Remove the Interior Side Racks

4. Take the Interior Side Racks to a
sink or dishwasher for a thorough
cleaning. Use a mild soap and
water solution to clean these
items.

5. If necessary, clean the interior of
the oven with a damp cloth.
Wipe dry with a soft dry cloth.

6. Reassemble oven.

7. Clean the exterior of the oven
with a clean damp cloth.

HEAVY-DUTY CLEANING:
For heavy-duty cleaning, use warm
water, a degreaser, and a plastic,
stainless steel, or scotch-brite pad.
Never rub in a circular motion. Always
rub gently in the direction of the steel
grain. Rinse thoroughly and wipe dry
with a soft cloth.

STAINLESS STEEL CARE

CLEANING:

Stainless Steel contains 70 – 80% iron,
which will rust if not properly maintained.
Stainless Steel also contains 12 – 30%
chromium, which forms an invisible
passive, protective film that shields
against corrosion.

If the protective film remains intact, the
stainless steel will remain intact.
However, if the film is damaged, the
stainless steel can break down and rust.

PREVENTIVE CARE:
To prevent stainless steel break­down, follow these steps:

Page 7

VCH & VRT SERIES OVENS F-38055 (11-09)

1. Never use any metal tools,

scrapers, files, wire brushes,
or scouring pads (except for

stainless steel scouring pads,)
which will mar the surface.

2. Never use steel wool – which
will leave behind particles that will
rust.

3. Never use acid-based or

chloride containing cleaning
solutions – which will break

down the protective film.

4. Never rub in a circular motion.
Always rub gently in the direction
of the steel grain.

5. Never leave any food products
or salt on the surface. Many
foods are acidic. Salt contains
chloride.

PRESERVING & RESTORING:
Special stainless steel polishing
cleaners can preserve and restore the
protective film.

Preserve the life of stainless steel with a
regular application of a high-quality
stainless steel polishing cleaner, as a
final step to daily cleaning.

If signs of breakdown appear, restore
the stainless steel surface. First,
thoroughly clean, rinse, and dry the
surface. Then, on a daily basis, apply a
high-quality stainless steel polish
according to manufacturer’s instructions.

HEAT TINT:
Darkened areas, called “heat tint,” may
appear on stainless steel exposed to
excessive heat. Excessive heat causes

the protective film to thicken. This is
unsightly, but is not a sign of permanent
damage.

To remove heat tint, follow the routine
cleaning procedure. Stubborn heat tint
will require heavy-duty cleaning. To
reduce heat tint, limit the exposure of
equipment to excessive heat.

MAINTENANCE

WARNING;

The Oven and its parts are HOT. Be
very careful when Operating,
Cleaning, or Servicing the Oven.

ALWAYS UNPLUG ELECTRICAL
POWER SUPPLY BEFORE
CLEANING OR SERVICING THE
CABINET.

DOOR GASKET:

At least once a week, thoroughly check
the door gasket for damage/wear. A
damaged gasket can cause inefficient
and unsatisfactory operation of the
oven.

If the gasket requires cleaning:

1. Gently wash gasket using a
moist cloth, a mild detergent
solution, and warm water.

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

3. Gently wipe dry with a clean dry
cloth.

Never apply food oils, or petroleum
lubricants directly to the gasket(s).
Petroleum based solvents and
lubricants will reduce the gasket’s life.

LOCKOUT / TAGOUT PROCEDURE

WARNING Always perform the LOCKOUT / TAGOUT
PROCEDURE of your facility before removing any sheet metal
