CASTER-EQUIPPED BROILERS
Broilers 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
broiler. If disconnection of the restraint is
necessary, turn off the gas supply before
disconnection.

GRIDDLE PLATE INSTALLATION
Put the griddle plate on top of the broiler. Duh.

BURNERS & CERAMIC BRICKS
a) Insert ceramic radiant brick ends at each
corner of the burner frame. Four are required
for each burner (Fig. 6).
b) Tilt ceramic radiant sideways to clear
burner and frame assembly, then lower
radiant into position with one flange resting
on burner ledge and one flange resting on
frame ledge.
c) Install the remaining radiants so 5 radiants
are located on each side of the burner.

VENTILATION HOOD
The broiler should be installed under a suitable
ventilation hood. For safe operation and proper
ventilation, keep the space between the broiler
and vent hood free from any obstructions.
GAS CONNECTION
The data plate indicates the type od gas and
pressure rate the unit is equipped to burn. DO
NOT connect to any other gas type.
GAS PRESSURE REGULATOR
INSTALLATION
A pressure regulator is supplied and must be
installed outside the broiler when making the
gas supply connection. The regulator is preset
at the factory for 6" W.C. (Water Column) for
Natural Gas; 10" W.C. for Propane. No further
adjustment should be required.
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).
Figure 8
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. The recommended maximum
supply pressure (upstream of the regulator) is
7" W.C. for natural gas and 11" W.C. for propane
gas. With all units operating simultaneously,
the manifold pressure on all units should not
show any appreciable drop. At no time should
the broiler be connected to supply pressure
greater than 1/2 psig (3.45 kPa) or 14" W.C.
CAUTION: All gas supply connections
and any pipe joint compound
must be resistant t o the
action of propane.
Purge the supply line to clean out any dust,
dirt, or foreign matter before connecting the
line to the unit.
Codes require that a gas shutoff valve be
installed in the gas line ahead of the broiler.
The gas supply line must be at least the
equivalent of 3/4" iron pipe.
When testing the gas supply piping system, if
test pressures exceed 1/2 psig (3.45 kPa), the
broiler and its individual shutoff valve must be
disconnected from the gas supply piping system.
When test pressures are 1/2 psig (3.45 kPa) or
less, the broiler must be isolated from the gas
supply piping system by closing its individual
manual shutoff valve during any pressure testing
of the system.

WARNING: PRIOR TO LIGHTING, CHECK
ALL JOINTS IN THE GAS
SUPPLY LINE FOR LEAKS.

WARNING: THE BROILER AND ITS
PARTS ARE HOT. USE
CARE WHEN OPERATING,
CLEANING, OR SERVICING
THE BROILER.
CONTROLS
OFF ONOFF ON

Figure 9
The broiler is a free vented appliance. All
products of combustion and the heat generated
by the burners pass through the grates. When
meat is placed on the grates, this blocks the
venting and causes a temperature buildup. The
broiler operates most efficiently with valves
turned down to 1/3 or 1/2.
LIGHTING THE GAS PILOT
1. Turn the individual burner gas valves off
and wait 5 minutes
2. Turn the incoming main gas supply valve
on. Light pilots through grate area by
extending a taper to the pilot lighter tube
up under the broiler area (Fig. 10).
3. To light the burners, turn the individual
burner valves on.
All orifices are of the fixed type and require no
adjustment.
Standing pilots should be adjusted via the
pilot adjustment valve to provide a slight yellow
tip on the flame. Pilots may be lighted by
extending a taper to the pilot lighter tube up
under the broiler area.
When broiling, turn burner control valves to 1/3
or 1/2 to prevent overheating.
Air shutters on the main burners must be
individually adjusted to provide a blue flame.
All traces of yellow should be adjusted out of
the burner flame. (See burner adjustment.)
When the grate is hot, scrape it with a wire
brush to keep the grate clean. Do not allow
debris to accumulate on the grate.
Turn flame to low setting during slack periods
to conserve energy.
Figure 10
TEMPORARY SHUTDOWN
Turn burner valves off.
COMPLETE SHUTDOWN
For complete shutdown, turn the main gas
supply valve off. (Make sure all individual
burner valves are off before relighting.)
