7
IS589 ECN4504
SUPPLY AND OPERATING 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 bottled gases.
Natural gas appliances are connected directly to the gas supply provided the inlet pressure is
regulated up stream to 20mbar.
Propane gas appliances require the fitting of a regulator at the inlet of the appliance where
the upstream pressure is regulated to 37mbar.
The set pressure for propane appliances is 30mbar with all burners in operation.
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 and/operating 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 plug can be removed to bleed the pipe work of air. When there is evidence of
gas flow at the test nipple the plug is to be refitted and made secure/leak free.
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 shall 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.
Radiant caps –The tops of the radiant caps will require brushing down to remove
build up of debris and ash that may have accumulated from previous cooking. They
may be removed to ease cleaning and must be refitted before use.
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 burner, select the corresponding 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 20-
30seconds and then fully rotate to the ignition position. Repeat as necessary until the
gas ignites at the pilot.
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 through the viewing port on the fascia
panel.
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.

12
IS589 ECN4504
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.
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. When lit a portion of the flame at the burner can be seen through the viewing port
on the fascia. After a few minutes there will be an evident glow radiating from the burner
through the radiant cap.
LIGHTING WHEN HOT
When a burner has become hot and the pilot has been extinguished ionization may occur at
the piezo ignition point when attempting to relight the pilot burner. In such a case then the
pilot in question should be allowed to cool for approximately 10 minutes or the pilot can be
relit using a taper provided the control knob is rotated to the ignition point and held in the
depressed state. Access to the pilot is through the viewing port on the fascia panel.
COOKING ZONES
Cooking zones are controlled by the gas valves. 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.
Use of griddle plates or large pans covering a significant portion of the cooking grid is
not recommended.
