A. Injectors replacement
• Ensure that the gas taps are in the
'OFF' position
• Isolate the hob from the electrical
supply
• Remove all pan supports, burner
caps, rings, crowns and control
knobs.
• With the aid of a 7mm box spanner
the burner injectors can then be
unscrewed and replaced by the
appropriate Natuaral gas injectors
(Fig.1).
B. Adjustment of minimum
level
When the hob has been fully installed it will
be necessary to check the minimum flame
setting. To do this, follow the procedure
below.
- Turn the gas tap to the MAX position
and ignite.
- Set the gas tap to the MIN flame
position then turn the control knob
from MIN to MAX several times. If the
flame is unstable or is extinguished
follow the procedure below.
Procedure:
To adjust the minimum level of the
burners, proceed as follows:
• Light the burner.
• Turn the knob on the minimum
position.
• Remove the knob.
• With a thin screwdriver, adjust the by-
pass screw (Fig.2).
If changing from LPG to natural gas
unscrew about 1/4 turn the by-pass
screw, until a small regular flame is
obtained.
If changing from natural gas to LPG,
completely tighten clockwise the
screw, until a small regular flame is
obtained.
• Repeat the adjustment procedure for
all burners.
• Finally check the flame does not go
out when quickly turning the knob
from the maximum position to the
minimum position.
This procedure can easily be carried out,
anyhow the hob has been positioned or
built in the working top.
