IS461ECN3410
SUPPLY PRESSURES
The appliance is connected directly to the gas supply where the gas supply pressure is
controlled at the source of inlet in the building or via the regulator attached to the bottled
gases.
See Technical Data for the supply pressures.
NOTE
For those destination countries where the supply pressure exceeds the supply
pressures given in the Technical Data above a regulator must be fitted and the
supply pressure set to the pressures detailed.
To gain access to the gas pressure test nipple the fascia panel requires removal. The test
nipple is situated at the left hand end of the manifold rail.
Remove the blanking screw and attach a pressure gauge to the boss of the test nipple to
check the supply pressure.
FIRST TIME LIGHTING
The procedure for first time lighting may only be carried out by registered personnel.
To light any individual burner it may be necessary to purge all pipe work of air. To do this
through the pilots alone could take some considerable time. With the fascia panel removed
the test nipple can be removed to bleed the pipe work of air. When there is evidence of
gas flow the test nipple must be made secure.
Refit the fascia panel and control knobs. A small amount of air will need to be purged from
each of the pilot lines.

USER INSTRUCTION
APPLIANCE USE
This appliance is only for professional use and should only be used by qualified personnel.
Ensure that the person responsible understands how to light, safely operate, clean and
shut down the appliance and is made aware of the position and operation of the gas
isolating cock in the event of an emergency.
ROUTINE CLEANING
It is important that users of the appliance systematically check and clean down as
necessary areas of the grill that have accumulated oils, fats and other combustible
debris from previous cooking. This is to prevent the potential risk of fire. Cleaning of
the appliance and its parts must be done when the appliance is cold and before the
start of service.
Areas to Check
• Branding grids – The spaces between the grids may become clogged and will
need to be cleaned to ensure even and clean cooking. Regular use of the scraper
supplied with the appliance will help keep the tops and the spaces of the branding
grid clean and clear.
• Radiants – The tops of the radiants will require brushing down to remove build up
of debris and ash that may have accumulated from previous cooking.
• Debris Collection Drawers – The drawers will need to be emptied of debris and
cleaned from old fats and oils that may have accumulated from previous cooking.
LIGHTING SEQUENCE
The operation of each burner is identical. Each valve has its own built in piezo ignition.
• To light the gas at a pilot, select the corresponding control knob depress the control
knob and rotate 90o anti-clockwise to the position marked with a stylized star to light
the gas at the pilot.
Should the pilot not light the first time maintain the control knob in this
position for a few seconds to allow a free flow of gas through to the pilot.
Return the control knob to the 'OFF' position and repeat the lighting
sequence. A portion of the pilot flame can be seen between the firewall and
the radiant corresponding to the chosen burner. Part of the pilot flame can
also be seen by looking at an angle through the ventilation slots on the
firewall.
• After establishing the flame at the pilot; maintain the control knob in the depressed
position for approximately 15 seconds to retain the flame at the pilot. Confirmation of
the established flame is made by releasing the control knob.
If the pilot flame goes out repeat the process until the flame is maintained.
Leave the pilot lit for a further 45-60 seconds to allow the flame failure sensing element to
heat to its full potential.
11
IS461ECN3410
• To light the gas at the corresponding burner rotate the control knob to any point
between the low rate and full rate as denoted by the small and large stylized flames on
the control knob.
If the appliance has stood unused for any length of time it may be necessary to purge
the pilot lines of air. To purge the pilot lines of air depress and rotate a control knob
until spring tension is felt. Maintain the knob in the depressed position for 2030seconds and then fully rotate to the ignition position. Repeat as necessary until the
gas ignites at the pilot.
COOKING ZONES
Each branding grid is its own cooking zone and is controlled by its own gas valve. The
cooking temperature can be controlled at any point between the low rate and the full rate.
After lighting, each zone can be left on pilot standby.
DEBRIS COLLECTION DRAWERS
It is recommended that each drawer is filled with a small volume of water before the start
of service. Any fats or oils from the cooking process falling through to the drawers will form
a film on the water whilst heavier pieces of debris will lie on the base of the drawer.
At regular intervals during quieter times of service the drawers should be periodically
checked for the level of water and emptied of collected debris as necessary.
USING THE APPLIANCE
For first time use it is recommended that the branding grids are 'seasoned'.
To season the grids, lightly coat the cooking surfaces with cooking oil. Place the grids back
on to the appliance and heat the grids to season.
Before the start of daily service flip the branding grids and heat at full power for 10 minutes
to carbonize the previous day's deposits. Remove debris using the scraper. Lower the
temperature of the zones to the desired cooking temperature.
