The SCB series Char Broiler is a commercial gas cooker intended for the cooking of
meat, seafood, pita bread and stockpot heating. The SCB features ‘flame arrestor’
broiling grates that control fat flare-up and ensure uniform broiling temperatures. The
specially designed cast iron grates have an angled grease trough to ensure all food
waste and fat runs off to enable the equipment to operate at its optimum
performance. The grates are removable to allow the radiants to be quickly and easily
cleaned. The broiling grates are reversible so they can be either flat or angled
depending on the food product being cooked. Steel baffles positioned under each
burner reflect heat up to the radiants and ensure the grease drawer and drip pan
area remains at a relatively lower temperature. The finned heat radiants situated
under the grates control cross draughts within the SCB Char Broiler to maintain a
constant cooking temperature for maximum efficiency and optimum cooking results.
The piezo ignition system enables the appliance to be lit without removing the grates
and radiants. The piezo igniter lights the pilot burner. One piezo igniter is used for
two pilot burners.

The SCB Char Broiler is supplied with adjustable stainless steel legs for bench
mounting

5.0 OPERATING THE SCB SUPER CHAR BROILER.

5.1 LIGHTING INSTRUCTIONS –PIEZO IGNITION.

It is not necessary to remove the grates and radiants when using the piezo ignition
system. However in certain instances the grates and radiants may be removed.

WARNING! Before attempting to remove the grate and radiants ensure
they are at an acceptable temperature to touch and handle. This will
normally take approximately 3 hours after turning off the main burner.

1. Ensure the gas supply to the SCB is turned
‘on’.

2. Push in and turn the
control knob approximately 30
degrees anti-clockwise to the
ignition point indicated by the

star (*) symbol as shown in
photograph 3.

IGNITION POSITION PILOT
GRATES AND RADIANTS.
PHOTOGRAPH 2.

3. Push and hold the control knob in for approximately 5 seconds to release gas
from the pilot burner jet and then press the piezo igniter. Normally only 2 or 3
‘clicks’ are required to ignite each pilot burner.
Hold the control knob in for 10 to 15 seconds
before releasing. This allows the flame failure
control system to heat up to its normal
operating temperature. If the pilot burner does
not remain illuminated wait three minutes and

try again. This ignition position (*) allows the
pilot light to burn continuously. In a cold kitchen
the heat up time may be longer, up to
20 seconds.

5.2 USING THE SCB CHAR BROILER.

The following notes provide general guidance on the operation of the SCB Char
Broiler.

• Apply cooking oil to the grates before use. Excess grease will run forward and
drip onto the front grease trough.

10

• When the SCB Char Broiler is loaded with food product adjust the gas valves to a
lower setting to prevent overheating causing the food to char.

• The grates must be scraped with a wire brush to keep them clean. Do not allow
debris to accumulate on the grates.

• Adjust the flame to the low setting or pilot burner during slack periods to conserve
energy.

• The SCB Char Broiler is a free venting appliance. All the products of combustion
and heat generated during cooking pass through the grates. When food product
is placed on the grates the ventilation is partially blocked causing a temperature
build-up. The appliance will operate more efficiently in these circumstances with
the gas valves adjusted down one third to one half.

5.3 REVERSING THE GRATES.

The slope of the grates can be altered to suit the type of product being cooked. The
shape of the casting at the far end allows the grates to be positioned either with a
slope to the front trough of the appliance or flat, as shown below. The angled
position is used for the cooking of meat and fish products where any oil or fat must
run into the trough situated at the front of the appliance. The flat position enables
pans to be heated on the top of the unit.

WARNING! Before attempting to alter the grate positions ensure they are
at an acceptable temperature to touch and handle. This will normally take
approximately 3 hours after turning off the main burner.

6.0 CLEANING.

DO NOT HOSE OR PRESSURE CLEAN THIS SCB CHAR BROILER.
INDIVIDUAL PARTS MAY BE PRESSURE CLEANED. REFER TO THE

FOLLOWING SECTION.
DO NOT USE ANY ABRASIVE CLEANERS
REFER TO THE RELEVANT COSHH DATA SHEETS PRIOR TO USING ANY
CLEANING PRODUCTS.
WEAR APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.

Prior to cleaning the appliance extinguish the main and pilot burner flames, isolate
the gas supply using the locally fitted isolating valve and ensure the appliance is at
an acceptable temperature to handle prior to cleaning.

6.1 CLEANING THE GRATES.

WARNING! Before attempting to remove the grates ensure they are at an

acceptable temperature to touch. This will normally take approximately 3

hours after using with the main burner.

1. Scrape the grease trough cast into the grates so the grease flows uninhibited

into the gutter and drawer. This will reduce the risk of flare-up.

2. The grates may be laid in the flat position and the burners then turned on full

to burn off excessive fat and carbon. When the grates have cooled off, clean
thoroughly with a wire brush.

3. The grates may be immersed in a strong commercial non-toxic cleaning

solution over night. In the morning flush with hot water and steam clean to
remove any debris.

4. To clean the front gutter, remove the grates and lift out the gutter. Wash

thoroughly with a hot detergent solution.

6.2 CLEANING THE RADIANTS.

Occasionally the cast iron radiant situated under the grates may require cleaning.

WARNING! Before attempting to remove the grates and radiants ensure

they are at an acceptable temperature to touch. This will normally take

approximately 3 hours after using with the main burner.

1. The radiants may be cleaned thoroughly using a wire brush or by immersing

in a strong commercial non-toxic cleaning solution over night. In the morning
flush with hot water and steam clean to remove any debris.

6.3 CLEANING THE EXTERIOR SURFACES.

When the appliance is cool, the gas control knobs and stainless steel surfaces may
be cleaned with a mild soap and water solution applied with a damp cloth. Rinse
the surface with clean water and dry with a soft cloth. Do not use an abrasive or
strong liquid cleaner on the stainless surface since they may damage the finish.

CAUTION ABOUT USING "SPRAY-ON" CLEANERS

surfaces may cause burns.

The SCB Char Broiler must not be installed next to open burners or fryers. Other
types of gas fired appliances can be positioned adjacent to the SCB Char Broiler
however there must not be any obstruction to the front.

Before proceeding with the installation, remove the protective plastic film from all
panels. Use an appropriate cleaning product to remove any adhesive residues from
the stainless steel.

18

When installing never enclose the unit’s lower area in any way that would obstruct
the flow of air into the appliance.

Crevices need to be avoided between and behind the appliance, and pipe work
where any spillage may lodge.

All supports shelves and wall finishes must be capable of withstanding a minimum
temperature of 65°C and be non-combustible.

The SCB must be secured in position to prevent any movement. Restraints must not
be fixed to the gas supply pipes or points not sufficiently anchored.

For any ‘work’ performed in the UK on the appliance including installation that is
within the scope of the Gas Safety (Installation and Use) Regulations shall be carried
out by a business that is CORGI approved (Council for Registered Gas Installers)
and approved by the Health and Safety Executive (HSE).

The SCB Char Broiler shall have a single manual isolating valve to be used when
servicing or cleaning.

A manual operation valve must be fitted to the gas supply to the catering area to
enable it to be isolated in an emergency. Ideally this valve should be located outside
the catering area or near an exit in a readily accessible position.

On completion of the installation a leak test must be performed. CAUTION!
A naked flame must not be used for this purpose. Leak test solutions may
cause corrosion therefore thorough rinsing with water is required after

testing.

8.4 MOUNTING OF THE APPLIANCE.

The SCB Char Broiler must be mounted on a flat surface. The appliance is supplied
with 4 off legs 100 mm high (4”) to ease cleaning underneath. This appliance is not
suitable for building in to other appliances.

Select a suitable flat level surface that can support the weight of the SCB Char
Broiler and food product (refer to table 2 for weights and dimensions). The unit must
be installed on a horizontal flat surface. Once the appliance is in position adjust the
feet to ensure the unit is level to within 1mm in 1 metre side to side and front to back.
The SCB Char Broiler must be adequately secured and restrained in position.

8.5 GAS PIPE WORK.

The installation of the gas pipe work in the UK must be in accordance with latest
revision of standard BS6173.

• Gas pipe work must be installed in a sound and workman-like manner and be
constructed of materials suitable for its purpose.

• Pipes conveying gas must be adequately identified.

19

• For rigidly fixed pipe work a union or similar method of disconnection must be
provided between the isolation valve and appliance.

• The clearance between the gas pipe and wall must be at least 25mm to ease
cleaning.

• Semi-rigid pipe must conform to BS7838 and only be installed in a ventilated area
where it cannot be damaged.

• If a flexible connection is installed it must not touch the floor or be exposed to
excessive heat.

• The gas outlet to which the connection is made must be located in the same
room as the appliance.

• If a flexible connection is used it must not be concealed within or routed through
any wall or partition.

• Flexible gas connections must not come into contact with sharp edges or wiring.

8.6 VENTILLATION.

Provision is required for adequate dispersal of combustion and cooking fume
products, supply of combustion air and ventilation for the appliance and cooking
processes. Adequate fresh air is required in kitchens to provide air for combustion to
limit the effects of heat and humidity (reference must be made to HVCA DW/171 to
ensure there is adequate ventilation for the appliance). Refer to table 2 for the typical
ventilation rate. Consideration must be made for other gas appliance that may be in
the same area as the SCB Char Broiler.

This type ‘A’ appliance is not designed to be connected to a flue or other device for
evacuating the combustion products to the outside of the room where it is installed.
The appliance must be installed in a suitably ventilated room in accordance with
current regulations (BS6173).

It is advisable that a hood is fitted above the appliance to ensure effective extraction
of combustion fumes and cooking odours. The plan dimension of the canopy should
exceed the plan area of the SCB Char Broiler by an overhang of 250mm at the front
and 150mm at the ends. The hood and ductwork must be constructed from non­combustible material. Table 2 specifies the ventilation airflow requirement.

For new installations the gas supply to the appliance must be interlocked with any
mechanical ventilation system fitted to ensure safe operation of the appliance.

The SCB must not be installed in a catering area where the ventilation system could
adversely affect its safe operation.

Broiling produces greasy cooking odours and vapours that require filtration. The
filters must be reviewed frequently and cleaned on a regular basis (at least every
month).

The SCB Char Broiler must be supported on a suitably designed surface that will
withstand the weight of the appliance and food product. The appliance must be
restrained to prevent any movement during use.

20

Low level ventilation is always required for appliances using a gas (LPG) heavier
than air.

It is strongly recommended that a flammable gas and CO detector is fitted that is
suitable for catering environments.

8.7 GAS INSTALLATION.

When installed in the United Kingdom the installation must conform to
the Gas Safety (Installation and Use) Regulations. This appliance must
be earthed as shown in section 9.9.

It is strongly recommended that a flexible connection be used for the gas supply to
the appliance.

Refer to table 2 and the appliance data plate to ensure there is an adequate supply
of gas. Check that the gas type and gas pressure is consistent with the gas supply of
the SCB. If the appliance is not suitable for the gas being supplied it shall not be
installed or connected to the gas supply.

Conversion of the appliance from one gas to another must be carried out strictly in
accordance with Hobart instruction’s by a competent person.
