Indesit P 640 A GB Instructions For Installation And Use Manual page 8

•
Reassemble the parts following the instructions in
reverse order.
•
On completing the operation, replace the old rating label
with the one showing the new type of gas; the sticker
is available from our Service Centres.
If the gas pressure is different than that prescribed, a
pressure regulator must be installed at the source, in
compliance with national standards governing the use of
piped gas regulators.
Regulation of Air Supply to the Burner
The burners do not need a primary air regulator.
Minimum Regulation
•
Turn the gas valve to minimum.
• Remove the knob and turn the regulator screw
(positioned either on the side of the top or inside the
shaft) clockwise until the flame becomes small but
regular.
N.B.: In the case of liquid gas, the regulation screw must
be fully screwed in (clockwise).
•
Make sure that, when the knob is turned rapidly high
to low, the flame does not go out.
•
In the event of a malfunction on appliances with the
security device (thermocouple) when the gas supply
is set at minimum, increase the minimum supply levels
using the regulator screw.
Once the adjustment has been made, apply sealing wax,
or a suitable substitute, to the old seals on the by-pass.
