Installation
Adapting the Hob for Different Types of Gas
To adapt the hob to a different type of gas than that for
which it was designed, (see the sticker under the hob or on
the packaging), the burner nozzles must be changed, as
follows:
• Remove the pan supports and slide the burners out of
the hob.
• Unscrew the nozzles using a 7mm socket wrench and
replace them with those for the new type of gas. (See
table 1, “Burner and Nozzle Specifications”).
• 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 Hotpoint Service (see KEY CONTACTS,
back page).
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 any primary air regulator.
Minimum Regulation
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 - Figs. A
and B) 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 in Fig. A - B.
Once the adjustment has been made, apply sealing wax,
or a suitable substitute, to the old seals on the by-pass.
