INSTALLATION
VENTILATING HOOD
The broiler(s) must be installed under a
properly designed ventilating hood. The hood
should extend at least 6” beyond all sides of
the unit. The hood should be connected to an
adequate mechanical exhaust system.
Information on construction and installation of
ventilating hoods may be obtained from the
“Standard for the Installation of Equipment for
the Removal of Smoke and Grease Laden
Vap ors f ro m Com merc ial Co okin g
Equipment”, NFPA No. 96-1987, available
from the National Fire Protection Association,
Batterymarch Park, Quincy, MA. 02269.
It is also necessary that sufficient room air
ingress be allowed to compensate for the
amount of air removed by the ventilating
system. Otherwise, a subnormal atmospheric
pressure will occur which may interfere with
burner performance or may extinguish the
pilot flame. In case of unsatisfactory broiler
performance, check with the exhaust in the
“OFF” position.
ASSEMBLY
Ceramic radiants, Figure 1 & 2, are located on
each side of the burners. Ceramic end pieces
are installed at both ends of each burner
assembly. Five (5) ceramic radiants are
installed on each side of each burner with the
pointed side facing down and the holes facing
up (See Figure 3).

materials and accessories from broiler interior.
Legs
Some broilers are mounted on legs.
Screw the legs into the modular stand.
Tightly screw the complete leg assembly into
the mounting holes in the bottom of the broiler
at each corner. If the unit is intended for curb
installation, no legs are provided. The curb
must be noncombustible material.

1. Insert ceramic end pieces at front and rear
of the burner frame. Four (4) are required
for each burner.
2. Tilt ceramic radiants 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 edge.
Floor Mounted Ranges
1. Place the first unit in the exact position it
will occupy in the battery.
2. Using a carpenter’s level, level the unit
front to rear and side to side. An
unleveled unit will adversely affect
performance. Adjust as follows:
FLOOR INSTALLATION ON LEGS
Level by turning foot on leg.
CURB INSTALLATION
Place shim under the low side. This operation
is important since variations in floors and
curbs are common. Unless units are level,
aligning the gas supply manifold will be
difficult and the units will not fit together tightly.
3. Remove the valve panel from the broiler.
4. Move the unit into position.
3. Install the remaining ceramic radiants so
that five (5) ceramic radiants are located
on each side of the burner.
LOCATION
Adequate clearance for service and proper
operation must be provided at the front, top,
sides, and back. The combustion air openings
are provided in the front of the unit and must
not be obstructed.
LEVELING
After broiler is positioned, check that
appliance is level both side-to side and front-to
back.

5. Engage union nut on manifold with male
fitting on next unit and draw up union nut
hand tight. Be sure appliances meet
together both front and rear. If manifolds
do not align, then units are not level. In
extreme cases it may be necessary to
loosen manifold bolts and adjust.
6. Continue leveling and connecting gas
supply manifolds together until all
appliances in battery are connected.
7. Tighten manifold gas union. Use backup
wrench to prevent manifold from rotating.
Failure to do this may result in damage
to the pilots and gas valves.
GAS CONNECTION
Before connecting the broiler(s) to the gas
supply line, be sure that all new piping has
been cleaned and purged to prevent any
foreign matter from being carried into the
controls by the gas. In some cases, filters

INSTALLATION
or drops are recommended. A separate gas
shutoff valve must be installed upstream from
the gas pressure regulator adjacent to the
broiler and located in an accessible are.
It is important that adequately sized piping be
run directly to the point of connection at the
broiler with as few elbows and tees as
possible. Consult your local gas company for
proper piping size and gas pressure. Each
broiler has a 3/4” NPT manifold input located
at the lower left rear of the broiler, Figure 4.
On dual broilers, each broiler must have a
separate regulator.
NOTE: Pipe joint compound or thread sealant
that is used should be resistant to action of
liquefied petroleum gases.
3/4” NPT Gas Inlet
Gas Inlet
(Figure 4)
Install the gas pressure regulator with gas
flowing as indicated by the arrow on the
regulator. The arrow must be pointing in
toward the unit. Use pipe compound or thread
sealant and carefully thread regulator to pipe
so that there is no cross threading, etc., which
could cause leakage.
1. Apply wrench only to the flat areas around
the pipe tapping at the end being threaded
to the pipe to avoid possible damage to the
regulator body which could result in
leakage.
2. Connect the gas supply line from the
service gas shutoff valve to the inlet side of
the gas pressure regulator using 3/4” pipe.
Avoid kinks or sharp bends that could
restrict gas flow.
NOTE: If flexible or semi-flexible connectors
are used, an AGA listed flexible connector
with an I.D. equal to 3/4” pipe must be used.
WARNING
DO NOT USE A DOMESTIC TYPE
FLEXIBLE GAS CONNECTOR.
3. Turn gas shutoff valve on and carefully
check for gas leaks immediately. Do this
before attempting to operate the broiler.

INSTALLATION
THE BROILER IS DESIGNED FOR USE
WITH A PRESSURE REGULATOR. THE
REGULATOR(S) SUPPLIED WITH THIS
UNIT MUST BE USED.
For Natural Gas
This gas pressure regulator is factory adjusted
for 6.0” W.C. manifold pressure. The rated
inlet pressure to the regulators should not
exceed 1/2 psig (3.45 kPa).
For Propane Gas
This gas pressure regulator is factory adjusted
for 10.0” W.C. manifold pressure. The rated
inlet pressure to the regulator should not
exceed 1/2 psig (3.45 kPa).
The broiler is equipped with fixed orifices for
use with a manifold pressure of 6.0” W.C. for
natural gas and 10.0” W.C. for propane gas.
Position the gas pressure regulator outside
the broiler as near to the unit as possible.
CAUTION
3. Make sure that the regulator is mounted in
the horizontal position with the arrow going
in the direction of the gas flow.
4. Remove the main burner control valve
knobs, Figure 5.

5. Remove the control valve panel by
removing two screws.
THE GAS PRESSURE REGULATOR MUST
BE LOCATED OUT OF THE HEAT ZONE TO
PREVENT DAMAGE TO THE REGULATOR.
ADJUSTMENT PROCEDURE
WARNING
DO NOT ALLOW UNTRAINED PERSONNEL
TO MAINTAIN OR SERVICE THE GAS
PRESSURE REGULATOR.
1. Before adjusting the regulator, check the
incoming gas line pressure into the
regulator. Incoming pressure must be 8.0”
W.C. for natural gas, or 14” W.C. for
propane gas.
2. If incoming pressure is not correct, have
the gas source checked and adjusted.
6. Connect a manometer to the pressure tap
provided on the broiler unit gas piping
manifold, Figure 6.
7. Check the manometer reading. The
reading must be 6.0” W.C. for natural gas,
or 10.0” W.C. for propane gas. (DYNAMIC)
8. If incoming line pressure is not correct,
adjust the regulator. Remove the seal cap
on the top of the regulator.
9. Insert a slot screwdriver into the top of the
regulator.
10. Turn the adjust screw clockwise to
increase the pressure, or counter
clockwise to decrease the pressure.

1. Turn the main gas shutoff valve to the on
position.
NOTE: Pilots are on at all times if main shutoff
valve is in the on position and pilot adjustment
valves are open.
2. Light each pilot.
BURNER ADJUSTMENT
The efficiency of the broiler depends on a
delicate balance between the supply of air and
the volume of gas at each main burner
resulting in complete combustion. Whenever
this balance is disturbed, poor operating
characteristics occur. An air shutter, Figure 9,
on the front of each main burner controls the
air supply.
