ELECTRICAL CONNECTIONS

WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE

APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL

ELECTRICAL CODES.

WARNING: DISCONNECT THE ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE

DISCONNECT SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT.

Bring conduit containing the proper supply wire (size and type in accordance with latest edition of the

National Electrical Code ANSI/NFPA-70) to the broiler. Use wire suitable for 167°F ( 75°C) on broilers

carrying more than 80 amps. On Models VB2S, VB22S, VB21 and VB221, the conduit enters into the

broiler through the 2" (51mm) hole located in the bottom of the broiler. On Models VTMB2 and

VTMB22, the conduit enters through the clearance hole provided in the back and is terminated on the

vertical panel behind the terminal block.

Connect the supply leads to the terminal block and the green grounding lead to the labeled ground lug.

Broilers designed for 220/380 or 240/415 volts require voltage supplies with grounded neutral

(3 phase, 4 wire; or 1-phase, 3-wire).

INSTALLATION

UNPACKING

Immediately after unpacking, check for possible shipping damage. If the broiler is found to be

damaged, save the packaging material and contact the carrier within 15 days of delivery.

Remove all shipping wire, wood blocking, and accessories.

Before installing, verify that the electrical service agrees with the specifications on the rating plate

located as follows: VTMB units - on the control panel front; VB21 - behind the oven door on the breaker

box cover; and VB2S - behind the door panel of the storage cabinet base. If the supply and equipment

requirements do not agree, contact your dealer or Vulcan-Hart immediately.

OPERATION

WARNING: THE BROILER AND ITS PARTS ARE HOT. BE CAREFUL WHEN OPERATING,

CLEANING OR SERVICING THE BROILER.

CONTROLS

Broiler

Infinite Load Switches — Two switches independently control the front and rear heating elements

in 208 and 240 volt models. The switch located on the left-hand side

of the switch panel controls the percent on-time of the two front

elements, and the switch located on the right-hand side of the switch

panel controls the two rear elements. The percent on-time of the

infinite load control varies from approximately 10% in the VERY LOW

position to 100% in the HIGH position.

3-Heat, 4-Position Switch —

On 480 volt models, each of the two non-cycling 3-heat, 4-position

switches control independently the front and rear sections of the

broiler.

Input varies from full power at the HIGH position (both

elements

connected in parallel) to MED position (one element only

on) to LO

position (both elements connected in series).

Grid Handle — The distance of the grid surface from the elements is controlled by the

pull-and-release grid handle at the right of the broiler. This grid handle

locks in 13 positions over the 6" (152 mm) grid travel.

The operator can, by independent setting of each switch, provide a wide range of broiler temperatures

depending on the type and location of the broiling product.

Oven

3-Heat Switches — Two switches (located on the right side of the switch panel, on each

side of the thermostat) independently control the top and bottom

heating elements. At HIGH position, the maximum element power

is utilized (elements connected in parallel); at MED position, only one

of the two elements is on (about

power); at LO position, the two

elements are connected in series (about 1/4power); at the

OFF

position, both elements are completely turned off.

Thermostat — Controls the temperature of the oven from 175°F to 550°F (79°C to

288°C).

Indicator Light — (Mounted next to the thermostat.) When lit, the thermostat is calling

for heat, and when off, indicates the desired temperature is

reached.

– 8 –

BEFORE FIRST USE

Before using for the first time, clean the broiler or oven with detergent and water. Rinse thoroughly and

wipe dry with a soft clean cloth.

Seasoning (Oven Models Only)

Lightly, but thoroughly, coat the oven steel deck with cooking oil and allow it to season in the oven at

450°F (232°C) for 30 minutes to 1 hour. This seasoning will lessen sticking of spillage and inhibit rust.

USING THE BROILER

Preheating

At full input, the elements will heat to broiling radiance in approximately 5 minutes. The broiler will

saturate for full loading in 10 to 15 minutes at full input.

Grid

The grid is the V bar type, which permits easy scraping with a steak turner during operation. Drippings

from the broiling food go through the grid onto the drip shield and into the grease collector.

Grease Collector

The grease collector collects grease and waste which is diverted by the tilt of the drip shield. DO NOT

allow the grease collector to overflow. The grease collector should be emptied when three-quarters

full to reduce the possibility of spillage.

USING THE OVEN

Preheating

Set top and bottom 3-heat switches to HIGH. Set thermostat to desired baking temperature. The

indicator light will light and remain lit until the oven reaches temperature. The oven may be loaded

when the indicator light goes off the first time; however, it is desirable to allow the indicator light to go

on and off at least twice so the oven is thoroughly heated and will brown baked products evenly. After

the first cycle (oven indicator light on and off), set the 3-heat switches as desired for baking. (Refer

to TIME, TEMPERATURE & SWITCH SETTING CHART FOR BAKING.)

When the thermostat is turned on, it provides power to the two 3-heat switches, which in turn, according

to their setting, independently turn the top and bottom heating elements on and off. Thus, while the

thermostat controls and maintains the oven temperature around the desired set temperature, the

3-heat switches control the rate of temperature build-up.

Baking

Approximate cooking times are given in recipe directions or are shown on the TIME, TEMPERATURE

& SWITCH SETTING CHART FOR BAKING shown below. When baking on the rack, it may be

necessary to set the bottom switch at HIGH.

Meat Roasting

Meat roasting is best performed in a balanced oven. Switch positions of HIGH and HIGH are

suggested, with the temperature control setting at the low temperature recommended by the American

Meat Institute and the Department of Agriculture. Top heat results in a well colored or carmelized finish

to meats. When roasting fowl and a heavily browned appearance is not desired, the top oven switch

should be set at MED or LO. The use of a meat thermometer is strongly recommended for all meat

roasting operations.

oven to the desired temperature, it is necessary for some baking products to turn the 3-heat switch

controlling the top elements to the MED or LO position in order to reduce the amount of radiant heat

applied to the particular product. This will eliminate burning of the top portion of the product.

Load the oven as rapidly as possible to prevent excessive heat loss. Place pans directly on the deck

and in rows back to front, beginning on the right, then the next row, etc., until oven deck is full. Do not

place pans closer to the door than 3" (76 mm). Do not let the pans touch the sides or back of the oven

or each other.

While it is recommended that you set the 3-heat switches to the HIGH position in order to preheat the

TIME, TEMPERATURE & SWITCH SETTING CHART FOR BAKING

This baking chart is a guide only. Recipes, mixing procedures, utensils and individual standards of

doneness, browning, etc., can result in variations in the precise time, temperature and switch settings

necessary to produce a satisfactory product.

High product quality can be obtained and maintained only if all phases of the baking operation are

properly performed. Variation in ingredients, under or overmixing, holding time before baking, etc., can

affect the texture, consistency and the basic quality of the product.
