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.

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.
