Installation
Gas Type Conversion
If the hob is to be converted for use with a type of gas other
than that for which it was set in the factory (indicated on the
data plate), the burner injectors must be replaced as follows:
Remove the pan supports and the burners.
Unscrew the injectors (“A” in fi gure below) using a 7 mm
socket wrench, and replace them with injectors of suitable
orifi ce diameter, as indicated on the appliance data plate.
Reassemble the parts.
If a regulator is required for the new gas type, instal an ap-
proved regulator of appropriate pressure setting and fl ow
capacity.
Replace the gas type label with one suitable for the new
gas type.
Check the turn down setting of each burner (next section)
and adjust where necessary.
Perform the post installation checks as described later in
this manual.
Adjust turn down setting
Put the tap to the low fl ame position;
Remove the tap knob and turn the adjusting screw, situ-
ated inside the tap stem using a fl at blade screwdriver
(loosening the screw increases the height of the fl ame,
tightening decreases it). Note: the adjusting screw must be
fully screwed down for LPG.
Having obtained the low fl ame setting required and with
the burner lit, abruptly change the position of the knob
several times from minimum to maximum and vice versa
and check that the fl ame does not go out.
Post Installation Checks
Perform post installation checks and ensure proper and
safe operation before leaving. Test all burners individu-
ally and in combination.
Leak Check
Ensure all gas control knobs are in the Off position.
Ensure the gas supply is switched on.
Spray a solution of soapy water onto all gas joints as well
as the full length of any fl exible hoses.
UNDER NO CIRCUMSTANCES USE A NAKED FLAME
IN CHECKING FOR LEAKS.
If bubbles appear anywhere, turn the gas supply off, check
all connections and retest. If satisfactory operation cannot be
achieved, contact place of purchase or their appointed agent
for service.
Flame check
Turn each burner on, and ensure that the fl ame is blue with
minimal yellow tipping. If there is signifi cant yellow tipping,
fl ame lift off or excessive noise, check pressure and adjust at
the regulator if necessary.
If satisfactory operation cannot be achieved, contact place of
purchase or their appointed agent for service.
Igniter operation
Check that the igniter for each burner successfully ignites the
gas.
If an igniter fails to work, fi rst remove the plug from the
electrical power outlet, and then check that all the electrical
connections are in place.
If satisfactory operation cannot be achieved, contact place of
purchase or their appointed agent for service.
Low fl ame setting
Check the low fl ame setting for each hob burner to ensure
that the minimum fl ame will not be extinguished by air
draughts.
Light the burner.
Turn the control until it engages in the minimum position.
Ensure the fl ame is stable and will not be extinguished by
air draughts.
To adjust the minimum fl ame:
Follow the procedure described in the gas conversion in-
struction.
