INSTALLATION, OPERATION AND CARE OF

GAS COUNTERTOP CHARBROILERS

GENERAL

Gas Infrared Charbroilers are designed for commercial use only and feature fast, efficient
gas heat. Each burner is controlled by an adjustable gas valve. Emitter panels are
located directly above each burner to maintain uniform temperature and provide infrared
cooking. Emitter panels and stainless steel cooking grids are easily removed for cleaning
when cool. A crumb tray is provided to collect fat run-off and debris; it opens to the front
for inspection or drain-off.

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.

Carefully unpack your charbroiler and make sure that no parts are discarded with
packaging material. A pressure regulator designed to operate with the broiler has been
supplied and must be installed before the charbroiler is placed into service (Refer to GAS
PRESSURE REGULATOR INSTALLATION in this manual).

Before installing, verify that the type of gas (natural or propane) and the clearance
dimensions agree with the specifications on the rating plate which is located on the upper
front corner on the right side.

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 charbroiler 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 appliance. Do not obstruct the flow of flue gases
through and above the broiler's cooking grids. Position the broiler in its final location.
Check that there are sufficient clearances to service the broiler and to make the required
gas supply connection(s). Provide 36" clearance at the front for cleaning, maintenance,
service and proper operation.

This broiler is for use in non-combustible locations only.

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

the emitter panels in place will cause
poor performance and clogging of the

The emitter panels should rest on top of

front and rear burner tabs over each
burner. The emitter panels should be
placed in position with the flanged
edges pointing upwards. See Fig. 2.

LEVELING

It is important that the charbroiler is level front to back and left to right. Areas of uneven
heat distribution will occur on an unleveled unit. The charbroiler is equipped with
adjustable legs. Turn the feet at the bottom of the legs to adjust to level. The unit should
be rechecked for level anytime it has been moved.

VENTILATION HOOD

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

GAS CONNECTION

The data plate on the lower right side of the charbroiler indicates the type of gas your unit
is equipped to burn. DO NOT connect to any other gas type.

All 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
charbroiler. The gas supply line must be at least the equivalent of ¾” iron pipe.

A pressure regulator is supplied and must be installed outside of the broiler when making
the gas supply connection. Standard orifices are set for 4"WC (Water Column) for
Natural Gas — 10"WC (Water Column) for Propane. Use the

1

/8” pipe tap on the burner
manifold for checking pressure. Make sure the gas piping is clean and free of
obstructions, dirt, and piping compound.

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 charbroiler 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 charbroiler must
be isolated from the gas supply piping system by closing its individual manual shut-off
valve during any pressure testing of the system.

-

6 -

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 4” 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 broiler 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 broiler (Fig. 3) and the regulator is positioned with the vent plug and adjustment
screw upright (Fig. 4).

Fig. 3

Fig. 4

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 charbroiler be connected to
supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.

CASTER EQUIPPED CHARBROILERS

Charbroilers 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 Quick­Disconnect Devices for use With Gas Fuel, ANSI-Z21.41 • CSA 6.9. In addition, adequate
means must be provided to limit movement of the broiler without depending on the
connector and the quick-disconnect device or its associated piping to limit broiler
movement. Attach the restraining device at the rear of the charbroiler. 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 charbroiler to its installation
position.

OPERATION

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

cleaning or servicing the charbroiler.

BURNER LIGHTING

The VTEC charbroiler does not have a pilot
and each burner lights directly from a spark
igniter or from an outside ignition source (such
as a lit taper, long handle lighter, etc).

LIGHTING BURNER WITH SPARK IGNITER

1. Turn the main gas shut-off valve and the
individual burner control knobs to the OFF
position (clockwise until stops). Wait 5
minutes.

2. Push and turn the burner control knob to the
MAX setting (counterclockwise to vertical/90°
position) on the burner you intend to light.
(Fig. 5)

3. Immediately, while viewing through the
burner sight hole, turn the igniter knob
clockwise until you hear a click (approx. ¼
turn) and see the spark. The burner should
ignite immediately and flames should be
visible through the burner sight hole.

4. If the burner fails to light immediately,
repeat step 3, two more times. If the burner
has still not ignited at this point, turn the
main gas shut-off valve and all burner
valves to the OFF position (clockwise until
stops) and proceed with manual burner
lighting instructions on following page.

5. Repeat steps 2-4 until all burners are lit.
Turn on one burner control knob at a time
and ensure burner is lit before proceeding
to light the next burner.

2. Apply a flame from an outside ignition source
(such as a lit taper, long handle lighter, etc)
directly to the gap between the bottom of the
emitter panel and the top of the intended
burner box at the front of the unit. See Fig. 7.

TO COMPLETELY SHUTDOWN THE BURNERS

For complete shutdown: Turn the main gas supply valve OFF. Make sure all individual
burner valves are OFF (turned completely clockwise until stops).

PREHEATING THE CHARBROILER

Allow the charbroiler to preheat for 20 minutes on the maximum (MAX) setting. Rub
grates with cooking oil before using to help reduce sticking.
