CONVERSION INSTRUCTIONS
CONTENTS OF THE KIT
THIS MANUAL IS AN INTEGRAL PART OF THE APPLIANCE. TAKE GOOD CARE
OF IT AND KEEP IT TO HAND THROUGHOUT THE APPLIANCE'S LIFE CYCLE.
INSTALLATION MUST BE CARRIED OUT BY QUALIFIED STAFF IN
COMPLIANCE WITH THE RELEVANT REGULATIONS. THE MANUFACTURER
DECLINES ALL LIABILITY FOR IMPROPER USES OTHER THAN THOSE
STATED ABOVE.
This kit, for separate sale, has been specially designed to convert the
barbecue from LPG to NATURAL GAS.
It contains all the components and instructions necessary for the
conversion procedure.
The appliance is set in the factory to operate on LPG. The conversion
procedure (requiring the kit described below) involves replacement of all
the burner nozzles, adjustment of the primary air flow of the barbecue
section burners only, and adjustment of the minimum flame setting on the
gas taps.
On completion of these operations, replace the “regulated for gas” label on
the rear of the barbecue with the one supplied in the kit.
The installation work must be carried out by a skilled technician.
WARNING: Keep all the nozzles factory-fitted on the appliance, the union
supplied and the “regulated for gas” label. It might be necessary to convert
the appliance back from NATURAL GAS to LPG in the future.
When converting back to LPG the conversion procedure is exactly the
same as that described below for NATURAL GAS.
The contents of the natural gas conversion kit are listed below:
• NATURAL GAS NOZZLES.
• 5/8" TO 1/2" GAS MALE UNION.
• SEAL.
• "REGULATED FOR" LABEL (TO BE APPLIED AFTER CONVERSION).

Instructions for the Installer
CONNECTION TO THE MAINS GAS SUPPLY
Connect the appliance to the mains
natural gas supply using a rubber or
steel hose in accordance with the
relevant regulations.
Screw the 5/8”-1/2” union (B)
supplied onto the barbecue's gas
inlet (C).
Screw the union (A) onto the union
(B) fitting the seal (D) between
them, as shown. Fit the hose (F)
onto the union (A) and secure it with
a band clamp (E).
Check that all the conditions listed below are met:
• the hose must be fixed to the hose connector with a safety band clamp;
• the hose must be accessible for inspection along its entire length (max. 1.5 m).
• the hose must not touch hot surfaces at any point (max. 50°C).
• there must not be any traction forces or stresses acting on the hose or any
tight bends or kinks in it.
• the hose must not touch sharp components or edges.
• if the hose is not perfectly gastight and causes gas leaks, do not attempt
to repair it ; replace it with a new hose.
• check that the hose's expiration date has not been passed.
If the appliance has been mounted on the optional trolley, lock the wheels
using the clamps provided. Any pulling or tension on the hose might
reduce the appliance's safety level.
