SAVE THESE INSTRUCTIONS

GENERAL

Vulcan ranges and ovens are produced with quality workmanship and material. Proper installation,
usage and maintenance of your range will result in many years of satisfactory performance.

The manufacturer suggests that you thoroughly read this entire manual and carefully follow all of the
instructions provided.

INSTALLATION

UNPACKING

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

Carefully unpack range(s) and place in the approximate installation position, whether as a battery or
single stand-alone range. Remove all shipping wire and wood blocking. Remove parts (packed in a
cardboard box) from oven cavity, or cabinet body or on top of modular range(s).

Before installing, check the electrical service (Convection Oven Models only) and type of gas supply
(natural or propane) to make sure they agree with the specifications on the rating plate located on the
lower left-hand corner of the front frame behind the bellcrank. If the supply and equipment
requirements do not agree, do not proceed with the installation. Contact your dealer or Vulcan-Hart
immediately.

ASSEMBLY

Ranges Mounted on Casters

Ranges mounted on casters must use a flexible connector (not supplied
by Vulcan) that complies with the Standard for Connectors for Movable
Gas Appliances, ANSI Z21.69 • CSA 6.16 and a quick-disconnect
device that complies with the Standard for Quick-Disconnect Devices
for Use With Gas Fuel, ANSI-Z21.41 • CSA 6.9. In addition, adequate
means must be provided to limit movement of the appliance without
depending on the connector and the quick-disconnect device or its
associated piping to limit appliance movement. Attach the restraining
device at the rear of the range as shown in Fig. 1.

Fig. 1

If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect
this restraint prior to turning the gas supply on and returning the range to its installation position.

Separate instructions for installing casters to the range are included with the casters.

Bumper Bars

CAUTION: Failure to install bumper bars may cause

motor damage and will void the warranty.

Remove existing #10 screws. Position bumper bars as
shown in Fig. 2. Replace #10 screws and secure
bumper bars.

Fig. 2

Battery Installation

If you are installing a new battery range to an existing field appliance manufactured before January
1998, the union on the existing field appliance must be checked against the union being used on the
new range. The union manufacturer's name around the face surface of the union nut must match. If the
new range has been shipped using a Ward union and the old appliance has something different — i.e.,
Stockham — it must be replaced with a Ward union (Fig. 3). Failure to replace this union could result
in a gas leak.

If a Ward union is needed for installation, it must be ordered through the Vulcan-Hart Parts Depot (Part
No. FP-088-89).

Fig. 3

Questions or concerns regarding the above installation procedures may be addressed by calling a
Vulcan-Hart Service Agency. (refer to our website, www.vulcanhart.com for a complete listing of
Authorized Service and Parts depots).

Proceed with the battery installation as follows:

1. Move next range into position and level as explained in LEVELING. Engage union nut on
manifold pipe with male fitting on next range and draw up union nut hand-tight. Be sure
ranges butt both front and rear. If manifolds do not line up, then ranges are not level. Do not
adjust manifold brackets to make manifolds line up, except in extreme cases, because this
will cause gas valves not to line up perfectly with manifold cover holes. Bolt top frames

1

together, using 10-24 x

/2 " (12.7 mm) bolts (packed in plastic bag in range oven).

– 6 –

2. Continue leveling, connecting manifold pipe and
bolting top frames of ranges together until all ranges
in the battery are connected, and then tighten
manifold unions gas-tight. Use wrench to keep
section of union assembled to pipe from rotating.
Failure to do this may result in misalignment of valve
stems.

3. Unpack high shelves or backguards and remove
backsplashes.

4. Place high shelf or backguard in position (see
ASSEMBLY — RISER, BACKGUARD AND HIGH
SHELF in this manual).

5. Replace back tops and backsplashes.

6. If front plates do not line up perfectly, adjust by
means of bolts under front plate. Similar front
adjustment is provided for the one-piece cast-iron
griddle (Model GH60) (Fig. 4).

Fig. 4

Riser, Backguard and High Shelf

Remove the shipping brackets on the corner of the range where a high shelf support casting is to be
bolted. It is not necessary to remove either shipping bracket on ranges equipped with a backguard as
the brackets will be used for support when remounting the rear top plate and backguard backsplash.

1. Carefully unpack riser, backguard or high shelf with the back down, on floor in front of range.
Remove backsplash panel from riser, backguard or high shelf.

2. Remove top castings, back top and shipping brackets from the range. Identify top casting(s) so
they are replaced in the same positions on the same range as when received from the factory.

When assembling a riser, backguard or high shelf to batteried equipment, remove only the extreme right
and left shipping brackets of setup section requiring mounting (Fig. 5).

Fig. 5

– 7 –

3. Carefully lift riser, backguard or high shelf over range (Fig. 6).

4. Carefully guide support channels into the two openings provided at the rear of the range (Fig. 7).

Fig. 6

Fig. 7

While lowering support channels into openings, be sure that the lower angle flange of the riser,
backguard or high shelf is positioned outside the flue back (Fig. 8).

Fig. 8

Once the backguard is setting in place on the range, install the left and right end caps. End caps simply
slide on, in between the splasher and the backguard. There is a tab on the cap that can be pulled out
or pushed in (with a screwdriver) to adjust cap for tightness. Two caps are packaged with each
backguard in a separate plastic bag. Be sure to look for caps in the backguard box. See Figs. 9, 10,
11 and 12.

3. Triangle-shaped Bricks (4) — Place two each side (Fig. 15).

Fig. 15

4. Large Bricks (2) — Set in center support as shown in Figs. 14 and 15.

5. The griddle plate is packaged separately from the range. On the top burner box front area of the
range, locate the coiled thermostat bulb and capillary assembly. Gently uncoil the capillary line.
Lift the griddle plate onto the range top, being careful not to crush the thermostat bulb or capillary.
Wedge a 2 x 4 under the front part of the griddle to hold up the plate. This will be necessary to install
the thermostat bulb into the V-slot bracket, located on the under side of the griddle plate.

6. Feed the thermostat bulb and capillary up over the heat shield and through the notched area
supplied in the shield (Fig. 16).

Fig. 16

– 10 –

7. Slide the thermostat bulb through the V-slot bracket (Fig. 17). Neatly coil the excess capillary line
without kinking and lay resting in front of the heat shield. Do not pinch the line when reinstalling
the control cover.

NOTE: The bulb should not be exposed and should be completely encased inside the V-slot
bracket. Also take care to insure that the capillary line is not exposed in any way to the burner
flame.

Fig. 17

LEVELING

Unlevel range(s) will create battery installation problems in lining up the manifolding system, and result
in uneven cooked product. Using a carpenter's level, level the range(s) from front to rear and side to
side. With range in its exact location or battery position, adjust leg heights. If installing a battery of
equipment, begin with first unit in battery lineup. Adjust legs by turning feet until all legs are resting on
the floor. If "less legs base" or "toe base" is used, screw the leveling bolt until floor contact is made (Fig. 18).

Fig. 18

The casters provided for the ranges are the nonleveling type; therefore, the floor must be reasonably
level or baked products will be uneven and performance will be inconsistent.

– 11 –

GAS CONNECTIONS

CAUTION: All gas supply connections and any pipe joint compound used must be resistant to
the action of propane gases.

Remove oven bottom(s) and baffles.

Remove upper manifold panel(s).

Connect gas supply to the range(s). Make sure the pipes are clean and free of obstructions, dirt and
piping compound.

Codes require that a gas shutoff valve be installed in the gas line ahead of the range(s).

Ranges manufactured for use with propane gas are equipped with fixed orifices.

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR
LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.

Single Range Installations

All single stand-alone ranges require installation using a regulator (design-certified by a nationally
recognized testing lab to the applicable ANSI standard) for an outlet (manifold) pressure of 6" (1.49 kPa)
Water Column for natural gas supply, and outlet (manifold) pressure of 10" (2.49 kPa) Water Column
for propane gas supply (available from Vulcan-Hart). The regulator must be adjusted to agree with the
pressures indicated on the rating plate. When installing the regulator, follow instructions supplied by the
regulator manufacturer.

Manifold pressure for the incoming store line must be at least 7" (1.74 kPa) Water Column for natural
gas and 11" (2.74 kPa) Water Column for propane gas.

If a pressure regulator is not installed, the warranty on related parts, as well as performance-related
problems, will not be covered.

Battery Installations

The gas manifold of this range, or the battery of which it is a part, must be installed using a regulator
design-certified by a nationally recognized testing lab to the applicable ANSI standard (regulators
available from Vulcan-Hart). The pressure regulator must have a maximum regulation capacity to
handle the total connected load and must have an adjustment range for manifold pressure marked on
the range rating plate. If the manifold pressure of the connected ranges is not the same, a separate
regulator must be supplied for all ranges operating under different manifold pressure ratings.

If a pressure regulator is not installed, the warranty on related parts, as well as performance-related
problems, will not be covered.

TESTING THE GAS SUPPLY SYSTEM

1

When test pressures exceed

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

disconnected from the gas supply piping system.

When test pressures are

1

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

system by closing its individual manual shutoff valve.

– 12 –

FLUE CONNECTIONS

DO NOT obstruct the flow of flue gases from the flue duct located on the rear of the range. It is
recommended that the flue gases be ventilated to the outside of the building through a ventilation
system installed by qualified personnel.

A minimum of 18" (45 cm) must be maintained between the grease removal device and the cooking
surface.

Information on the construction and installation of ventilating hoods may be obtained from the standard
for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition), available from the National
Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

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 TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES.

WARNING: APPLIANCES EQUIPPED WITH A FLEXIBLE 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.

If your range is not equipped with a grounding plug and electric supply is needed, ground the range by
using the ground lug provided (refer to the wiring diagram which is packaged in a clear plastic ziplock
bag located within the oven cavity on the oven rack).

Do not connect the range to electrical supply until after gas connections have been made.

OPERATION

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

CLEANING OR SERVICING THE RANGE.

BEFORE FIRST USE

Seasoning of Cast-Iron Hot Tops and Even-Heat Tops

These tops are made of cast iron and should be seasoned prior to use. To season, pour a small amount
of cooking oil (about 1 ounce [28 grams] per square foot [.09 square meters] of surface) over the top.
With a cloth, spread the oil over the entire surface to create a thin film. Wipe off any excess oil with a
cloth. Turn burners on very low and allow to heat up gradually for about 2 hours. Repeat this procedure
a second time before regular use. This will resist cracking of the cast iron and ensure longer life.

Cleaning Griddle Plate at Start-Up

The griddle plate is shipped covered with a protective coating of grease. Remove this film only when
the griddle plate is being cleaned prior to its first cooking use. Remove film by scraping the griddle
surface with the straight edge of a large piece of stiff cardboard. For cleaning procedures, see
CLEANING - GRIDDLE TOP in this manual.

Seasoning of Griddle Plate

CAUTION: This griddle plate is steel, but the surface is relatively soft and can be scored or
dented by carelessly using a spatula. Be careful not to dent, scratch or gouge the plate surface.
Do not try to knock off loose food that may be on the spatula by tapping the corner edge of the
spatula on the griddle surface.

A new griddle surface must be seasoned to do a good cooking job. The metal surface of the griddle is
porous. Food tends to get trapped in these pores and stick; therefore, it is important to "season" or "fill
up" these pores with cooking oil before cooking. Seasoning gives the surface a slick, hard finish from
which the food will release easily.

To season, heat the griddle to a low temperature 300 to 350°F (148 to 176°C) (use a surface
temperature gauge) and pour on a small amount of cooking oil (about 1 ounce [28 grams] per square
foot [.09 square meters] of surface). With a cloth, spread the oil over the entire griddle surface to create
a thin film. Wipe off any excess oil with a cloth.

Repeat this procedure two to three times until the griddle has a slick, mirrorlike surface.
