Pressure testing
The gas pressure can be measured at one of the
hotplate burner jets. Make sure that the cooker is not
connected to the electricity supply. Lift off a burner
head. Fit the pressure gauge to the jet. Turn on one of
the other burners and light it with a match. Turn on the
control for the hotplate burner to which the pressure
gauge is fitted. Press in the knob to allow the gas
through and register the pressure on the gauge.
For Natural Gas cookers the pressure should be
20mbar.
For LP Gas cookers the pressure should be
29mbar for Butane
37mbar for Propane.
Reassemble burner top, making sure it is reassembled
in the correct way on the burner body.
Electrical Connection
WARNING: THIS COOKER MUST BE EARTHED.
All external wiring must comply with the IEE
Regulations for the Electrical Equipment of Buildings.
Connection to the electrical supply can be made with
either a plug and socket or be permanently wired via
a double pole switch. The cooker is supplied with a 3
core cable 2m long. If a replacement cable is fitted it
must be 250v high temperature PVC (85°C), 1mm
2
.
Should the plug not fit the socket in your home, it
should be removed and replaced with a suitable plug.
Note: If a plug is fitted which is not suitable, it must be
cut off and disposed of properly. To avoid the risk of
electrocution, the plug must not be left where children
might find it and plug it into a supply socket.
Three pin plugs to BS1363 with a capacity of not less
than 13A must be used and fitted with a 3 amp fuse
‘ASTA’ approved to BS 1362.
After replacing the fuse the cover must be refitted.
If the cover is lost, the plug must not be used until
a replacement cover has been obtained from your
supplier. The colour of the correct fuse carrier is that of
the coloured insert in the base of the fuse recess, or
stated elsewhere on the plug. Always state this colour
when ordering a replacement fuse carrier.
IMPORTANT The wires in the mains lead are coloured
in accordance with the following code:-
GREEN AND YELLOW: EARTH
BLUE: NEUTRAL
BROWN: LIVE
The wires should be connected into the terminal of
your plug as shown:
Electrical checks
EARTH CONTINUITY CHECK
The cooker must be disconnected from the power
supply. Set your meter to (ohm) on the X1 scale and
adjust to zero if necessary.
Test the leads from any of the cooker’s earth points
(e.g. inside electric box cover) - to the earth pin on
the cooker’s plug - resistance should be less than
1 (ohm). If it is not, check all the earth wires for
continuity. Check that all contacts are clean and
tight. Re-check. If the resistance is still greater than
1 (ohm) there may be a problem, consult a qualified
electrical engineer.
POLARITY CHECK
The cooker must be connected to the power supply.
Your meter should be set on 300V ac scale.
Test at the cooker terminal block:
1. Test leads from L to N. Your meter should read approx.
220-240V ac.
2. Test leads from L to E. Your meter should read approx.
220-240V ac.
3. Test leads from N to E. Your meter should read approx.
0-15V ac.
If the readings are different from these values there
is an electrical fault. Rectify any fault and repeat the
test. If necessary repeat the test at the supply system
socket/spur - if the fault also occurs at this stage then
there is a house system fault which requires attention
by the Electrical Authority.
The customer should be warned NOT to use the
appliance until this examination has been carried out.
Hotplate check
Check each burner in turn. Each burner has a flame
safety device (FSD) that stops the flow of gas to the
burner if the flame goes out.
For each burner, press ignition switch on facia panel
and push in and turn the knob to the solid flame
symbol ( ).
Keep holding the knob pressed in to let the gas
through to the burner for few seconds. If, when you
let go of the control knob, the burner goes out, the
safety device has not held in. Turn the control to the off
position and wait one minute, then try again this time
holding in the control knob for slightly longer.
Grill check
Open the grill compartment door.
The grill burner has a flame safety device (FSD) that
stops the flow of gas to the burner if the flame goes
out. Turn the knob to the large flame symbol ( ). Press
in the grill knob. This lets gas through to the burner.
Keep holding the knob pressed in and press the igniter
button or light with a match. Keep holding the button
for about 10 seconds
