NATURAL GAS TO LPG CONVERSION
This conversion must only be carried out by a competent person (i.e. a Gas Safe registered fitter).
Instructions to fit replacement injectors:
1. Disconnect the appliance from the gas and electrical supplies.
2. Remove burner components “B” and pan supports (Fig. 9).
3. Remove the injectors “A” (Fig. 9) with a socket spanner and replace with the corresponding
injectors.
Gas connection
• Accessibility: Make sure that it is possible to run gas lines to the gas connection point of the
appliance. The gas connection point must be accessible without having to remove the cooktop. If
a flexible hose is used, the connection point must also be accessible without having to remove
the cooktop.
Setting up minimum flow rates:
1. Remove the control knobs “M” (Fig. 10).
2. Turn on the LP gas supply, light the burners and turn the controls to the minimum position as
indicated by the small flame.
3. Insert a small screwdriver “D” (Fig. 10) into the hole at the top of the tap “C” and turn the
adjustment screw left or right until the flame of the burner is conveniently regulated to the low
position.
4. Make sure when turning quickly from full position to reduced rate position that the flame does not
extinguish.
5. Replace the knobs.
• ULPG connection: Using the supplied gas regulator, remove the dust seals on the inlet and outlet
ports and position the outlet port of the regulator towards the gas inlet pipe of the cooktop. Using a
suitable thread sealant, screw the regulator on and ensure that it is orientated with easy access to
the test point. Connect the appropriate ULPG supply to the inlet port of the gas regulator.
• Natural gas connection: Using the supplied gas regulator, remove the dust seals on the inlet and
outlet ports and position the “OUT” port of the regulator towards the gas inlet pipe of the cooktop.
Using a suitable thread sealant, screw the regulator on and ensure that it is orientated with easy
access to the test point. Connect the appropriate Natural Gas supply to the “IN” port of the gas
regulator.
