INSTALLATION AND OPERATION MANUAL
FOR HGB SERIES GAS CHARBROILERS
RETAIN THIS MANUAL FOR FUTURE REFERENCE
Vulcan-Hart HGB Series Gas Charbroilers feature
heavy-duty, cast iron burners; input rating is
16,000 BTU per burner. Each burner is controlled
by an adjustable gas valve. Baffles suspended
beneath the burners reflect the heat upwards
maintaining a cool zone under the burner. Special
cast alloy 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 (55⁄16" wide) are
reversible to allow all or part of the cooking grid
surface to be level or sloped. Grooves, cast in the
top grates, permit fat runoff and reduce flaring
when tilted towards the front.
The gas control valves can be adjusted to provide
ideal broiling results. Sectional heating is possible
as each valve controls one burner.

INSTALLATION
Before installing, verify that the type of gas
(natural or propane) agrees with the specifications
on the data plate located on the reverse of the
lower front control panel (remove 4 screws to
access).
Casters (Optional)
Also be sure the unit is built for the installation
elevation.
Models HGB34M, HGB50M, HGB60M and
HGB71M must be installed on a non-combustible
level counter or stand. No adjustment is provided.
UNCRATING
When a modular broiler is installed on a counter,
it must be sealed to the counter with an NSF
approved sealant.
The charbroiler was carefully 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 charbroiler is found to be damaged, save
the packaging material and contact the carrier
within 15 days of delivery.
Do not use the drawers or handles to lift or move
the charbroiler.
LOCATION
The equipment area must be kept free and clear
of combustible substances.
A minimum clearance of 2 inches must be
provided at the rear of the broiler to allow for gas
connection; no side clearance is required. The
charbroiler is intended to be installed only in
noncombustible locations.
Casters may be ordered either 2 fixed and 2
swivel with brake, or 4 swivel with brake.
Modular Broilers
INSTALLATION CODES AND STANDARDS
Vulcan-Hart charbroilers should be installed in
accordance with state and local codes, or in the
absence of local codes, with the National Fuel
Gas Code, ANSI-Z223.1 (latest edition), available
from American Gas Association, Inc., 1515 Wilson
Boulevard, Arlington, VA 22209, and with ANSI –
NFPA Standard #96 (latest edition), Vapor
Removal from Cooking Equipment, available from
the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269.
ASSEMBLY
Burners, radiants and top grates are shipped
inside the cabinet and must be assembled during
installation (Fig. 1).
Install the charbroiler in an area which has
sufficient air supply for combustion of the gas at
the burners. Provide adequate clearance for air
openings into the combustion chamber. Do not
obstruct the flow of combustion and ventilation
air.
Do not permit fans to blow directly at the
charbroiler and, wherever possible, avoid open
windows next to the sides or back. Avoid walltype fans which create air cross currents within
the room.
Legs
Legs or casters are factory assembled onto the
bottom of the charbroiler as specified on order.
Six inch legs may be painted or stainless steel.

GAS CONNECTIONS
CAUTION: All gas supply connections and
any pipe joint compound must be resistant to
the action of liquefied petroleum gases.
The gas inlet is located at the middle rear (offset
to right on HGB71). Codes require that a gas
shutoff valve (not included) be installed in the
gas line ahead of the charbroiler. A gas pressure
regulator is shipped with the charbroiler for
inclusion in the gas supply piping. The gas supply
line must be 11⁄4" NPT (inside diameter). Make
sure the pipes are clean and free of obstructions,
dirt, and piping compound.
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.
If it is necessary to disconnect the strain relief,
turn off the gas supply before disconnection.
Reconnect the strain relief before turning the gas
supply on and returning the unit to its installation
position.
GAS PRESSURES AND ORIFICES
The standard orifices are set at 6" W.C. (Water
Column) pressure for natural gas and 10" W.C.
(Water Column) pressure for propane.
TESTING THE GAS SUPPLY PIPING SYSTEM
When test pressures exceed 1⁄2 psig (3.45 kPa),
the charbroiler and its individual shutoff valve
must be disconnected from the gas supply piping
system.
After piping has been checked for leaks, fully
purge gas pipes to remove air.
When test pressures are 1⁄2 psig (3.45 kPa) or
less, the charbroiler must be isolated from the
gas supply piping system by closing its individual
shutoff valve.
CASTER EQUIPPED CHARBROILERS
LEVELING THE CHARBROILER
If the charbroiler is equipped with casters, the
gas connector (available from Vulcan-Hart) must
comply with the Standard for Connectors of
Movable Gas Appliances, ANSI-Z21.69 (latest
edition), and CAN/CGA-6.16 ( latest edition) and
a quick-disconnect device that complies with the
Standard for Quick-Disconnect Devices for Use
With Gas Fuel, ANSI-Z21.41 (latest edition) and
CAN/CGA1-6.9 (latest edition).
Once gas connections have been made, place a
spirit level on top of the charbroiler. Adjust the
legs to ensure that the charbroiler is level frontto-back and side-to-side in the final installed
position.
Provide a gas line strain relief to limit movement
of the charbroiler. Do not depend on the connector
and/or any quick-disconnect device or its
associated piping to limit the appliance
movement. Attach the strain relief to the rear of
the charbroiler (Fig. 2).
No adjustment is required for modular broilers.
FLUE CONNECTIONS
The charbroiler must be located under a hood
which has an adequate connection to an exhaust
duct. The hood must extend 6" beyond
charbroiler sides.
Adequate ventilation must be provided and must
comply with NFPA Standard #96, (latest edition),
and with local codes.
Clearance above the charbroiler should be
adequate for products of combustion to be
removed efficiently. An 18" minimum clearance
should be maintained between the flue vent and
the filters of the hood venting system.
Adequate air should be provided in the kitchen to
replace air taken out by the ventilating system.
This will prevent charbroiler function from being
affected by a reduced atmospheric pressure.

CLEAN BEFORE FIRST USE
Seasoning
Using a non-corrosive, grease-dissolving cleaner,
clean the protective metal oils from all surface
parts. Follow the directions of the cleaner
manufacturer. Rinse all parts thoroughly and
wipe dry with a soft clean cloth. Reseason cast
iron parts immediately to prevent rusting.
Lightly season the top grates, and the griddle and
backsplash (if present) with a thin layer of cooking
oil. This should also be done after every cleaning.
OPERATION
WARNING: HOT PARTS CAN CAUSE BURNS.
USE CARE WHEN OPERATING THE BROILER.
CONTROLS (Fig. 4)
OFF – Horizontal when off.
LIGHTING THE MANUAL GAS PILOT
Adjustment of the pilot light must be performed
by a qualified Vulcan-Hart installation or service
person. The flame adjustment must be made at
the time of installation.
ON – Turn valve handle counterclockwise
90 degrees so it is vertical to open the
burner gas valve completely. Adjust
the valve between OFF and ON
positions to moderate the heat.
1. Turn main gas supply ON.
2. Wait 30 seconds, and, using a lighted taper,
light the pilots. The pilot for each burner must
be lit (Fig. 3).
3. If pilot fails to light, turn main gas supply
OFF. Wait 5 minutes and repeat.
Fig. 4
Pre-Heat
Turn burners fully on for 20 to 25 minutes to allow
the broiler to pre-heat. Valves should be turned
to a lower position to maintain grid temperature
between 525°F and 625°F for optimum broiling.
Fig. 3
Nightly Shutdown
Turn burner valves OFF; pilots will remain lit.
Complete Shutdown
1. Turn burner valves OFF.
2. Turn main gas supply OFF, pilots will go out.
6
Caution: Leaving the valves fully on beyond
the recommended pre-heat time will produce
grid temperatures in excess of 1000°F which
can cause radiants to warp.
Positioning the Top Grates
The top grates have two positions. With one side
up, the grids are horizontal (flat). With the other
side up, the grates slope toward the front. Use
the sloped grate for most broiling to allow the
groove on each side of the grid bars to catch the
melted fat and allow it to flow to the trough in
front. The grease will then flow through an
opening to the grease drawer.
Do not allow the meat being broiled to catch fire
as this results in a poor flavor. Fatty meats may
require reduced temperatures to minimize flames.
CLEANING
Top Grates
Clean the top grates daily on both the top and
bottom surfaces with a good wire brush or burlap
or other grease absorbing material to remove
spillover, grease, etc. before they burn in. Avoid
a crust on top of the grill; it looks unsightly and
slows cooking speed (scrape off if necessary).
Burn-off grates at full input after cleaning.
Burner Radiants
To prevent continuous smoking, keep the
charbroiler clean. Never allow grease or fat to
accumulate. Clean burner radiants daily with a
good wire brush. The radiants may be cleaned in
place or removed for a more thorough cleaning.
Steel wool may be used for more stubborn spots.
• Keep the broiler clean.
Grease Trough and Drawer
• Clean the grate grooves with the wire brush
provided.
Empty and clean the grease trough, drain and
drawer thoroughly at least once every day.
• Empty the grease drawer frequently.
Exterior Surfaces
Clean all exposed surfaces of the entire
charbroiler thoroughly at the end of each day.
Stainless steel may be cleaned with a damp
cloth; stubborn soil may be removed with
detergent and warm water.
MAINTENANCE
WARNING: HOT PARTS CAN CAUSE BURNS.
USE CARE WHEN MAINTAINING THE
BROILER.
BURNERS
If, after a period of satisfactory operation, burner
flame characteristics should change or length of
flame should be reduced, burner ports may have
become restricted. Burners should be cleaned at
least every 60 days and more often if required.
To clean burners, remove and boil in a strong
solution of lye water for about 15 minutes. Ports
can be opened with a sharp-pointed instrument
or proper sized drill bit. Be careful not to increase
the size of the burner ports.
If the mixer openings or pilot orifices need
cleaning, contact your Vulcan gas service
technician. This should be done at least every 6
months and more often if necessary.
