Gas Connection:
1. The data plate on rear or side of the Charbroiler indicates the type of gas
the unit is equipped to burn. DO NOT connect to any other gas type.
NOTE: Gas supply connections and any pipe joint compound must be
resistant to the action of propane gases.
2. Purge the supply line to clean out any dust, dirt, or foreign matter
before connecting the line to the unit.
3. Codes require that a gas shut-o 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.
4. A pressure regulator is supplied and must be installed outside of the
broiler when making the gas supply connection. Standard orices are
set for 4" W.C. for Natural Gas / 10" W.C. for L.P. 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.
5. 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"-9” W.C. for Natural gas and 10"-12”
W.C. for L.P. Propane gas is recommended. With all units operating
simultaneously, the manifold pressure on all units should not show any
appreciable drop.
6. When testing the gas supply piping system:
• If test pressures exceed ½ psig (3.45 k Pa), the Charbroiler and
its individual shuto valve must be disconnected from the gas
supply piping system.
• When test pressures are ½ psig (3.45 k Pa) or less, the Charbroiler
must be isolated from the gas supply piping system by closing its
individual, manual shut-o valve during any pressure testing of
the system.
WARNING
DO NOT use an open ame to check for leaks. Check all gas piping
for leaks with a soap and water solution before operating unit.
NE PAS utiliser une amme nue pour vérier les fuites. Vériez tous les
tuyaux de gaz pour les fuites avec de l'eau savonneuse avant de l'unité

Lighting Instructions
Conversion Note
PLEASE CHECK LEAKAGE BEFORE REINSTALLING CONTROL PANEL.
LIGHTING PILOT
The pilot light on the appliance has been set at the factory. A screwdriver
may be required for the rst lighting to adjust the ame for your elevation.
1. Turn o the manual valve and wait 5 minutes to clear the gas.
2. Turn all knobs to the "OFF" position.
3. Hold an ignition source (e.g: a lit match) at the pilot. When the ame is
established, remove the ignition source. If necessary, adjust pilot ame
height by turning pilot valve screw.
4. Turn the burner knobs to "ON". If the burner does not ignite, promptly
open the pilot valve more. If the pilot ame appears larger than
necessary, turn it down and reset burner ignition. The pilot ame should
be as small as possible but large enough to guarantee reliable ignition of
the burners when the knobs are turned to "ON".
LIGHTING MAIN BURNER
To light burner, turn knob to “ON”. Then back o to the desired ame level. The
range of adjustment is virtually innite between “ON” and “OFF”.
MAIN BURNER AIR SUPPLY
5. For ecient burner operation, a proper balance of gas volume and
primary air supply must be maintained, which will result in complete
combustion. Insucient air supply results in a yellow streaming ame.
Primary air supply is controlled by an air shutter on the front of the burner.
6. Loosen the screws on the front of the burner and adjust the air shutter
to just eliminate the yellow tips of the burner ame. Lock the air shutter
in place by tightening the screws.
4. Replace the front panel and knobs.
5. Before installing the included convertible regulator, unscrew the
octagon cap. You can read (NAT) on the plastic insert attached to the
head of the cap; ip it over and snap back in place (Fig.6).

Operation
Before operating the Charbroiler, check that it is sitting level. Adjust
the feet at bottom to straighten and level the unit.
NOTE
Upon first use, the unit can produce a metal-burning
smell. This is normal and the smell will decrease with use.
The Charbroiler and parts get very hot. Use caution when
operating, cleaning or servicing the unit.
CONTROLS
Each burner is individually controlled by heavy-duty innite control valves,
with an input of 35,000 BTU/h.
Safety
A WINCO® Approved Service Technician should carry out repairs if necessary.
Do not remove any components or service panels on this product.
Allow the unit to cool down before dismantling for cleaning; the unit will be
too hot to handle immediately after use!
Do not use hose or pressure wash to clean.
If the machine is damaged, it must be repaired by a WINCO Approved
Qualied Service Technician in order to avoid a hazard.
CAUTION • ATTENTION
NEVER ATTEMPT TO MOVE A CHARBROILER SECTION WHILE COOKING.
An unexpected are could cause severe injury. Turn o the unit, let it cool and
use potholders and/or gloves to reposition or remove.
The space between the legs at the bottom admits combustion air.
DO NOT BLOCK THIS SPACE.
Ne tentez jamais de déplacer une section de la grille pendant la cuisson. Une fusée
inattendu pourrait causer des blessures graves. Eteignez l'appareil, le laisser refroidir et
employer des gants isolants et/ou des gants pour repositionner ou supprimer. L'espace
entre les jambes en bas admet l'air de combustion.
NE PAS BLOQUER CET ESPACE.
All burners are lit from constantly burning pilots. Turning the valve to the
desired ame height is all that is required to put the unit in service.
Do not permit fans to blow directly at the unit. Wherever possible, avoid open
windows next to the unit's sides or back. Avoid wall type fans which create air
cross-currents within a room.
Tous les brûleurs sont allumés de pilotes brûlant constamment. Tourner la vanne à
la hauteur de amme désirée est tout ce qui est nécessaire pour mettre l'appareil en
service.
Ne pas permettre aux fans de souer directement à l' unité. Autant que possible, éviter
les fenêtres ouvertes à côté des côtés ou à l'arrière des unités. Évitez les fans de type
mur qui créent air contre-courants au sein d'une chambre.
It is also necessary that sucient air be allowed to enter the room to
compensate for the amount of air removed by any ventilating system.
Otherwise, a subnormal atmospheric pressure will occur, aecting operation
and causing undesirable working conditions.
Il est également nécessaire que l'air susant doit être autorisé à entrer dans la salle
pour compenser la quantité de l'air extrait par un système de ventilation. Sinon, une
pression atmosphérique inférieure à la normale aura lieu, aecter le fonctionnement
et causer des conditions de travail indésirables.
A properly designed and installed hood will act as the heart of the ventilating
system for the room or area in which the unit is installed, and will leave the
unit independent of changing draft conditions.
Un capot correctement conçu et installé agira comme le cœur du système de ventilation
