INSTALLATION, OPERATION AND CARE OF

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

Immediately after unpacking, check for possible shipping damage. If the hotplate is found
to be damaged, save the packaging material and contact the carrier within 15 days of
delivery.

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 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 6" to the back and 6" 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

• 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 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

If the hotplate is equipped with legs or is mounted on the optional stand equipped with
legs, 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

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 of 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

Gas regulator pressure is preset at 5” Water Column (W.C.) for natural gas, and 10” W.C.
for propane gas. Minor adjustments may be required based on site specific gas pressure.

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 adjustment
screw upright(Fig. 2).

Fig. 1

Fig. 2

The minimum supply pressure (upstream of the regulator) should be 7-9” W.C. for natural
gas and 11-12” W.C. for propane gas. At no time should the hotplate be connected to
supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.

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

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

OPERATION

The hotplate and its parts are hot. Use care when operating,

cleaning or servicing the hotplate.

CONTROLS

There is one pilot for every two burners. The hotplate is equipped with standing,
unmonitored pilots. Gas will flow from the pilots as soon as the main gas supply to the
unit is turned on. See pilot lighting procedure below.

Each burner is independently controlled by an infinite heat control valve. Once the pilots
are lit, turning the control knob to the ON position will light each burner. The burners will
be in the full ON position when the control knobs are turned all the way to the left. The
burners will be in the full OFF position when the control knobs are turned all the way to
the right.

LIGHTING INSTRUCTIONS

1. See Fig 5. Turn main gas shut-off valve

and all burner control knobs to the OFF
position and wait 5 minutes to allow
any accumulated gas to escape.

2. Remove grates.

3. Turn main gas shut-off valve ON.

Light the pilots. Adjust the pilot valve
screw(See Fig.6) until the pilot flame
has a slight yellow tip.

4. To light burners, turn individual burner

valves to the ON position.

5. If burners fail to light, turn all valves

and the main gas shut-off to the OFF
position and contact an authorized
service agency.

PILOTS

PILOT ADJUSTMENT

Using a flathead screwdriver, turn the slotted hex-head pilot adjustment screw clockwise
to decrease the flame, and counterclockwise to increase the flame. See Fig. 6.

CLEANING

The hotplate and its parts are hot. Use care when operating,

cleaning or servicing the hotplate.

Grates may be immersed in commercial cleaning compound overnight. In the morning,
rinse with hot water to remove any residues of cleaning compound. Thoroughly dry and
apply a cooking oil to prevent rusting.

Burner ports and burner rest should be thoroughly cleaned. Venturi must be free from
grease and lint. When cleaning, do not insert a pick into the burner port holes – soap and
water will normally do the job. Heavy spattering or spill-over may require cleaning with a
mild oven cleaner. After cleaning, rinse with clean water and dry with a dry cloth. Be sure
to apply a thin coat of cooking oil for protection after cleaning.

Stainless steel surfaces may be cleaned using damp cloth with mild detergent and water
solution.

Places where fat, grease, or food can accumulate must be cleaned regularly.

MAINTENANCE

The hotplate and its parts are hot. Use care when operating,

cleaning or servicing the hotplate.

LUBRICATION

All valves must be checked and lubricated periodically. Check with your service agency
for details.

VENT SYSTEM

At least twice a year the exhaust hood (venting system) should be examined and cleaned.
