- the minimum thermal capacity in the minimum position
First of all, check whether the unit is already fitted for the mains gas and pressure; in case of transformation for working with
other kinds of gas, carefully check the markings on the nozzles, the idle screw and by-pass with Tables II Injectors Sect. 2.5.

ADJUSTING THE MINIMUM THERMAL CAPACITY

The right minimum thermal capacity is obtained with the "calibrated" by-pass idle screw firmly tightened in accordance with
Table II Injectors Ignite the burner as described in Sect. 5 "User Instructions" on the maximum position (
approximately 5 minutes of pre-heating, turn the knob onto the minimum position (
minimum thermal capacity. For the 2nd and 3rd Families, the by-pass idle screw should be fully screwed into the cock (Fig.
1 pos. 2).
3.6

LIQUID GAS OPERATION CHECK

Check whether the fitted nozzles correspond to the information of Tables II Injectors Sect. 2.5.
Check whether the incoming pressure corresponds to the information of Table II.
Make sure that the L.P.G. system has two pressure regulators of sufficient capacity and that the evaporation capacity of the
system is sufficient.
See also the publication entitled "Installation Instructions and Specifications of LPG systems.".
3.7

OPERATION CHECK

- Start the unit according to the user instructions.
- Make sure there are no gas leaks following the local procedures.
- Check the ignition and inter-ignition of the pilot burner and main burner.
- Make sure the flue gases are discharged properly.
- Write on a sticker, to stick onto the unit data plate, the gas and pressure for which the unit has been calibrated.

USER'S INTRODUCTION

Explain the operation and use of the unit to the user by referring to the instructions booklet and illustrate any changes.
Leave the instructions booklet with the user and explain he needs it for further reference.
4. TRANSFORMING FOR OPERATION WITH ANOTHER TYPE OF GAS
4.1

HOB

- Take off the grills, burner lid and burner body.
- Remove the knobs.
- Take off the front panel.
4.1.1 REPLACING THE PLAQUE BURNER NOZZLE FIG. 1
Replace the nozzle (Fig. 1 pos. 2) of the burner (size-12 wrench) with one corresponding to the type of gas chosen, following
Tables II Injectors Sect. 2.5.
4.1.2 REPLACING THE PLAQUE PILOT BURNER NOZZLE Fig. 2
- Remove the two locking washers (Fig. 2 pos. 3).
- Lift the head of the pilot burner (Fig. 2 pos. 5).
- Replace the nozzle (Fig. 2 pos. 4) of the pilot burner using the size-5 wrench with one corresponding to the type of gas
chosen, following Table II Injectors Sect. 2.5.
- Before fitting the head (Fig. 2 pos. 5), adjust the primary air by turning its regulator (Fig. 2 pos. 6). Ignite the pilot light and
check the length and quality of the flame, which should neither be too weak nor too strong, but approximately 20 mm,
almost detached from the head and without a yellow tip (L.P.G.).
4.1.3 REPLACING THE "BY-PASS" IDLE SCREW
- Replace the minimum thermal capacity screw, by-pass (Fig. 1 pos. 1) with one corresponding to the type of gas chosen,
following Table II Injectors.
- The thermal capacity on the minimum position must be approximately 30% of the nominal thermal capacity. When you
turn the knob fast from the maximum position (
