INSTALLATION, OPERATION AND CARE OF
GAS COUNTERTOP CHARBROILERS
GENERAL
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. Grooves, cast in the top grates, permit fat runoff and
reduce flaring when tilted towards the front. A grease drawer is provided to collect fat
run-off; it opens to the front for inspection or drain-off.

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.
Before installing, verify that the type of gas (natural or propane) and the clearance
dimensions (see page 4) agree with the specifications on the rating plate which is located
on the upper 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

- 4-
supply connection(s). Provide 24" clearance at the front for cleaning, maintenance,
service and proper operation.
Minimum clearances to combustible construction are 12" to the back and 9" to the sides.
Minimum clearances to non-combustible walls are 3" to the rear and 3" to the sides.
INSTALLATION CODES AND STANDARDS

BURNERS, RADIANTS, AND TOP GRATES
The top grates are shipped flat (top-side
down) from the factory for stock pot use.
For broiling, the top grates can be left in
the flat position or reversed so they slope
forward for grease run-off. Remove the
cast iron radiants (Fig. 1) and inspect and
remove the shipping tape used during
shipping to hold the burners in place.
Reassemble the radiants and the top
grates. Unpack the supercharger burner
dividers and install between burners. The
tabs on the superchargers should be
inserted in the slots at the front of the fire
box.

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 unleveled 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 should 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.
CAUTION: All gas supply connections and any pipe joint compound must be
resistant to the action of propane.
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.
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.
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.

- 6-
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. 2) and the regulator is positioned with the vent plug and adjustment
screw upright (Fig. 3).
Fig. 2 Fig. 3
The minimum 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.
CASTER EQUIPPED CHARBROILERS
Charbroilers 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 Quick-
Disconnect 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 charbroiler. If disconnection of
the restraint is necessary, turn off the gas supply before disconnection. Reconnect the
restraint prior to turning the gas supply on and return the charbroiler to its installation
position.
Note: If the Charbroiler is installed on casters and is moved for any reason, it is
recommended that it be re-leveled (see LEVELING).
OPERATION
WARNING: THE CHARBROILER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING,
CLEANING, OR SERVICING THE CHARBROILER.

CONTROLS (Fig. 2)
Fig. 2
All orifices are of the fixed type and require no adjustment.
Standing pilots should be adjusted to provide a slight yellow tip on the flame. Pilots may be
lighted by removing adjacent cast iron top grates and radiants.
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. While making adjustments, you may notice
that some burners, especially to the far right and left, have a higher flame. This is part of the
unit’s design and is a normal effect.
When charbroiling, turn burner control valves to 1/3or ½ to prevent overheating.
Scrape top grates during broiling with a wire brush to keep the grates clean. Do not allow debris
to accumulate on the grates.
Turn flame to low setting during slack periods to conserve energy.
The charbroiler 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 build-up. The charbroiler operates most efficiently with valves turned
down to 1/3or ½.
LIGHTING THE GAS PILOT (Fig. 3)
1. Turn the individual burner gas valves OFF
and wait 5 minutes.
2. Remove the Top Grates. Turn the
incoming main gas supply valve ON.
Light pilots using a taper (Fig. 3).
3. To light the burners, turn the individual
burner valves ON. Fig. 3
TO COMPLETELY SHUTDOWN THE BURNERS AND PILOT LIGHTS
For complete shutdown: Turn the main gas supply valve OFF. (Make sure all individual burner
valves are off before relighting.)

PREHEATING THE CHARBROILER
Allow the charbroiler to preheat for 30 minutes. Rub grates with cooking oil before using. Note
that grease runs forward and drips into the trough in front of the charbroiler before draining into
the grease drawer
COMPONENT PARTS
The Achiever Charbroiler comes with several
standard parts as illustrated. Each can be
easily removed and installed easily by hand for
cleaning and maintenance. Note that the
Burner and Deflector are an assembly and are
NOT designed to be disassembled.
You will find that the two of the Burner-
Deflector assemblies on the extreme right and
left of your charbroiler have Deflectors that are
flat, and not bent as shown. For correct
operation ensure that the flat Burner-Deflector
assemblies remain on the right and left.
CLEANING
Scrape top grates thoroughly so grease flows to trough and grease drawer uninhibited. This
prevents flare ups.
Top grates may be immersed in strong commercial cleaning compound overnight. In the morning,
rinse with hot water to remove any residues of cleaning compound.
Stainless steel surfaces may be cleaned using damp cloth with mild detergent and water solution.
Places where fat, grease, or food can accumulate must be cleaned regularly.
MAINTENANCE
WARNING: THE CHARBROILER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING,
CLEANING, OR SERVICING THE CHARBROILER.
VENT SYSTEM
At least twice a year the exhaust hood (venting system) should be examined and cleaned.
SERVICE
Contact your local Service Agency for any repairs or adjustments needed on this equipment.
