CONVERSION INSTRUCTIONS

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.

CONTENTS OF THE KIT

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).

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.

Perform the operations described below on all the gas taps.

1 Pull off the knob. 2 Make sure that the by-pass inside is screwed fully

down. Use a screwdriver inside or on the side of the rod (see right).

3 Turn the bypass as stated in the BURNER

CHARACTERISTICS, NOZZLES AND GAS CONSUMPTION table (see page 10).

4 When adjustments are complete, fit the knob, light

the relative burner and turn it to the minimum

setting . The flame should be even at the minimum setting.

5 Check that the flame remains stable when the

knob is turned quickly from the maximum to the minimum setting. The flame must not go out.

6 If the minimum flame is not even, remove the knob

and make small clockwise or anti-clockwise adjustments to the bypass then check stability again. Otherwise the minimum flame has been adjusted successfully.
