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 shutdown the
appliance and is made aware of the position and operation of the gas isolating cock in the event of an
emergency.
LIGHTING SEQUENCE
•Open the main gas cock.
•Push in a control knob (LB or RB) and then rotate anti-clockwise to any position to allow gas
through to the burner. Manually light a corresponding burner to the tap using a taper or piezo
ignitor wand. If using a piezo wand, carefully place the wand tip on the ceramic plaque and draw
back slightly before clicking to light the gas.
•On establishing a flame at the burner, keep the knob depressed for approximately 15 seconds then
release. The burner should remain lit.
SHUT DOWN
To shut down the appliance rotate all control knobs clockwise to the OFF position. The gas supply
stopcock or bottle valve should now be closed.
SHELF POSITIONING
The height and angle of the shelf can be set by moving the handles LH and RH up a down in the
directions of the arrows shown. The LH handle lowers / raises the front edge of the shelf whilst the
RH handle lowers / raises the rear edge of the shelf.
BRANDING PLATE
The branding plate is intended to be mounted directly onto the shelf. To do this there are two holes at
the rear of the branding plate which are to be located on the pins at the rear of the shelf.
The height and angle of the branding plate is adjusted in the same way as the shelf.
GRILLING
Any food product to be cooked on the shelf or branding plate must be placed directly with the aid of
suitable tongs for the purpose to prevent injury from burns. Cooked food must be removed with tongs
whilst the appliance is in operation.

IS370 ECN3280 11
CLEANING
Ensure the appliance is cool and the gas supply is isolated before commencing cleaning.
The branding plate and shelf can be removed for cleaning purposes.
It is important that from time to time depending on frequency and duration of use that the
shelf, branding plate and grill pan be removed from the appliance so that the oven cavity can
be cleaned thoroughly. This is to prevent the build up of un-noticed debris, which could
potentially catch fire.
The drip tray should be regularly drained and kept clean to prevent the risk of fire.
The grill pan and all its component parts should be routinely removed from the appliance
and thoroughly cleaned.
After use, wash the unit down with a warm detergent solution.
Do not use abrasives on stainless steel or enamelled parts.
Do not use any products containing chlorine or hydrochloric acid to clean stainless steel
surfaces.
Do not clean the appliance using a water jet.
REMOVING PARTS
Before removing, any parts from the oven cavity ensure the appliance is off and has cooled to at least
a safe working level.
Ensure the drip tray has been emptied and lightly cleaned.
The branding plate can be removed from the shelf by lifting at the rear to free the branding plate from
the lugs on the shelf. The branding plate is heavy and assistance may be required.
To remove the shelf; lift the right hand side of the shelf and slide the shelf to the right to free the
shelf from the carriage arms.
The grill pan can now be removed from the appliance. The grill pan is heavy and assistance may be
required when removing from the oven cavity.
RISK OF FIRE
Do not place any combustible materials directly in front of the appliance whilst the
appliance is in operation.
Any combustible materials must be at least 800mm from the front of the appliance to
prevent the risk of fire.
LOADING OF THE SHELF OR BRANDING PLATE
The shelf and branding plate are produced from sturdy materials and can withstand heavy loading.
Whilst there is no restriction to loading the shelf or the branding plate, loading should be exercised
within practical application to prevent food products from burning.
