INSTALLATION, OPERATION AND CARE OF
GAS COUNTERTOP CHARBROILERS
GENERAL
Vulcan/Wolf Gas Countertop Charbroilers are designed for commercial use only and
feature fast, efficient gas heat. Each burner is controlled by an adjustable gas valve.
Cast radiants are located directly above each burner to maintain uniform temperature.
Radiants are easily removed for cleaning when cool.
Heavy-duty cast iron top grates are reversible to allow all or part of the cooking grid
surface to be level or sloped. A crumb tray is provided to collect fat run-off and debris;
it opens to the front for inspection or cleaning.

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 lower
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 top grate. 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 24" 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 3" to the rear and 3" to the sides.

These act as dividers between

some or all of the supercharger
burner dividers at your discretion if
you find your production method
works better without them. The
super charger burner dividers are
installed by inserting the hooks

Radiant – The charbroiler must
never be operated without the
radiants in place. They protect the
burner from food drippings and
heat up to provide an even heating
pattern. The radiants are installed
by inserting the tab thru the
corresponding slot in the heat
shield to the front (Fig. 4-A) and
the back of the radiants set on the
radiant rest to the rear (Fig. 5-A).

Burner
– The burner shutter
should engage the orifice to the
front (Fig. 6) and rest in the
burner slot to the rear of the unit.
Proper burner shutter adjustment
is important for optimal charbroiler
performance. The burner shutters
should only be adjusted with all
radiants in place. The shutter will
typically be about 50% open for
natural gas and 80 to 100% open
for LP. A properly adjusted burner
should exhibit solid blue flames
that are touching the burner. All
traces of yellow should be
adjusted out of the burner flame
for natural gas and only a slight
yellow tipping should be observed
on LP gas. Large, yellow tipped
flames typically indicate not
enough air and the burner shutters
should be opened slightly.
Floating flames (not touching the
burner) typically indicate too much
air and the shutter should be
closed slightly.

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 unlevel 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 must 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 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.
60” and 72” models have a gas inlet at each end of the unit. The unit will arrive from the
factory with a metal cap on one end and a plastic dust cover on the other. You may move
the metal cap to the other end and use which ever connection point is most convenient to
the available supply outlet. The plastic dust cover must be replaced with a metal pipe cap
if you do not use that location as the gas inlet. Do not connect both of the available
charbroiler gas inlets to the gas supply.
A pressure regulator is supplied and must be installed outside of the broiler when making
the gas supply connection. Standard orifices are set for 5"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.
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 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. 7) and the regulator is positioned with the vent plug and adjustment
screw upright (Fig. 8).
Fig. 7
The 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.

valve for each burner. To initially
light the burners, the knobs should
be turned to the “MAX” setting then
adjusted to the desire setting as
needed.
The burners will be off when the
control knob is turned all the way to
the right and pointing to “OFF”. The
burners will be at maximum setting
when turned all the way to the left
and pointing to “MAX”. A medium
burner setting can be achieved by
adjusting the knob approximately half
way between the “OFF” and “MAX”
marks. See Fig. 11.
The charbroiler is a free vented
appliance. All products of
combustion and the heat generated
by the burners passes through the
grates. When food products are
placed on the grates, this blocks the
venting and causes a temperature
build-up.
