MEDIUM DUTY GAS HOTPLATES

GENERAL

Gas Countertop Hotplates are designed for commercial use only and feature fast, efficient
gas heat. Each burner is controlled by an adjustable gas valve. Cast grates and burners
are easily removed for cleaning when cool.

INSTALLATION

UNPACKING

This hotplate was inspected before leaving the factory. The carrier assumes full responsibility for the
safe delivery upon acceptance of the shipment. Check for possible shipping damage immediately after
receipt.

If the hotplate is found to be damaged, complete the following steps:

1. Carrier must be notified within 5 business days of receipt.

2. Carrier’s local terminal must be notified immediately upon discovery (note time, date, and
who was spoken to), and follow up and confirm with written or electronic communication.

3. All original packing materials must be kept for inspection purposes.

4. The hotplate cannot have been moved, installed, or modified.

5. Notify Vulcan Customer Service immediately at 800-814-2028.

LOCATION

The installation location must be kept free and clear of combustibles. Do not obstruct the
flow of combustion and ventilation air. DO NOT install the hotplate adjacent to open
burners or fryers.

Sufficient air should be allowed to enter the room to compensate for the amount of air
removed by any ventilating system and for combustion of the gas burners. Do not
obstruct the air flow into and around the hotplate. Position the hotplate in its final
location. Check that there are sufficient clearances to service the hotplate and to make
the required gas supply connection(s). Provide 24" clearance at the front for cleaning,
maintenance, service and proper operation.

Minimum clearances to combustible construction are 11" to the back and 11" to the sides.
Minimum clearances to non-combustible walls are 0" to the rear and 0" to the sides.

INSTALLATION CODES AND STANDARDS
The hotplate must be installed in accordance with:

In the United States of America:

1. State and local codes.

2. National Fuel Gas Code, ANSI-Z223.1/NFPA #54 (latest edition). This shall include but
not be limited to: NFPA #54 Section 10.3.5.2 for Venting. Copies may be obtained
from The American Gas Association Accredited Standards Committee Z223, @ 400
N. Capital St. NW, Washington, DC 20001 or the Secretary Standards Council, NFPA,
1 Batterymarch Park Quincy, MA 02169-7471

NOTE: In the Commonwealth of Massachusetts

All gas appliances vented through a ventilation hood or exhaust system equipped with

a damper or with a power means of exhaust shall comply with 248 CMR.

3. NFPA Standard # 96 Vapor Removal from Cooking Equipment, latest edition, available
from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

In Canada:

1. Local codes.

2. CAN/CSA-B149.1 Natural Gas Installation (latest edition)

3. CAN/CSA-B149.2 Propane Installation Code (latest edition), available from the
Canadian Gas Association, 178 Rexdale Blvd., Etobicoke, Ontario, Canada M9W 1R3

CASTER EQUIPPED APPLIANCES

Hotplates mounted on stands with casters must use a flexible connector (not supplied)
that complies with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69

• CS A 6 . 1 6 an d 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 additio n, adequate
means must be provided to limit movement of the hotplate without depending on the
connector and the quick-disconnect device or its associated piping to limit hotplate
movement. Attach the restraining device at the rear of the hotplate. If disconnection of
the restraint is necessary, turn off the gas supply before disconnection. Reconnect the
restraint prior to turning the gas supply on and return the hotplate to its installation
position.

If the Hotplate is installed on casters and is moved for any reason, it is recommended
that it be re-leveled (see LEVELING).

LEVELING

Turn the feet at the bottom of the legs in or out to level the hotplate in the final installed
location. If the hotplate is mounted on the optional stand equipped with casters, position
the hotplate on a level floor.

VENTILATION HOOD

The hotplate should be installed under a suitable ventilation hood. For safe operation and
proper ventilation, keep the space between the hotplate and vent hood free from any
obstructions.

GAS CONNECTIONS

Fig. 1

Fig. 2

Gas supply connections and any pipe joint compound must be

resistant to the action of propane gases.

Purge the supply line to clean out any dust, dirt, or any foreign matter before connecting
the line to the unit.

Codes require that a gas shut-off valve be installed in the gas line ahead of the
appliance. The gas supply line must be at least the equivalent o f ¾” iron pipe.

An adequate gas supply is necessary. Undersized or low pressure lines will restrict the
volume of gas required for satisfactory performance. A minimum supply pressure of 7"
W.C. for natural gas and 11" W.C. for propane gas is recommended. With all units
operating simultaneously, the manifold pressure on all units should not show any
appreciable drop.

When testing the gas supply piping system, if test pressures exceed ½ psig (3.45 kPa),
the appliance and its individual shutoff valve must be disconnected from the gas supply
piping system. When test pressures are ½ psig (3.45 kPa) or less, the appliance must be
isolated from the gas supply piping system by closing its individual manual shut-off valve
during any pressure testing of the system.

Prior to lighting, check all joints in the gas supply line for leaks.

Use soap and water solution. Do not use an open flame.

GAS PRESSURE REGULATOR INSTALLATION

This hotplate is supplied with a convertible gas pressure regulator preset at 4” W at er
Column (W.C.) for natural gas. No further adjustment should be required.

Install the regulator as close to the hotplate on the gas supply line as possible. Make sure
that the arrow on the underside of the regulator is oriented in the direction of gas flow to
the hotplate (Fig. 1) and the regulator is positioned with the vent plug and the conversion
plug cover upright(Fig. 2).

- 5 -

The minimum supply pressure (upstream of the regulator) should be 7-9 ” W.C. for n atural

Fig. 3

gas and 11-12” W. C . for propane gas. At no time should the hotplate be connected to
suppl y p r e ssure greater than ½ psig (3.45 kPa) or 14” W . C.

PROPANE GAS CONVERSION

This hotplate is shipped from the factory equipped with fixed burner orifices for natural
gas operation. The burner orifices required to convert the hotplate to propane gas are
shipped with the hotplate in the shipping packaging. It is recommended that a trained gas
service technician with the necessary tools, instruments and skills perform the
conversion.

To convert to propane, following steps must be completed:

1. Remove all natural gas burner orifices and install the provided propane burner orifices.

2. Set the regulator to 10” W.C. by inverting the r egulator spring p lug . See Fig. 3.

Prior to lighting, check all joints in the gas supply line for leaks.

Use soap and water solution. Do not use an open flame.
