Bypass Screw Adjustment
The valves in this cooker are fitted with adjustable bypass
screws. The cooker is supplied with the bypass screws set for
Natural gas. For LPG conversion the bypass screws must be
screwed all the way down.
It may be possible to adjust the bypass screw by simply
removing the control knobs (Fig. 11.5). If however you
are unable to access the bypass screw using a suitable
screwdriver, you will need to remove the control panel, please
refer to section 'Removing the Control Panel' below.
Removing the Control Panel
Pull off all the control knobs and remove the fixing screws
underneath the control panel (Fig. 11.6).
The control panel will drop down slightly. Clear the holes
from the inner panel and pull the control panel forward. Take
care not to damage or strain the wiring.
Turn the bypass screw on each control clockwise to the stop
(Fig. 11.7).
Stick on Label
Stick the LP gas label over the natural gas part of the
appliance data label.
Pressure Testing
Connect the appliance to the gas supply.
The gas pressure can be measured at one of the hotplate
burner injectors (not the Wok burner).
Lift off a burner head. Fit the pressure gauge to the jet. Turn
on and light one of the other hotplate burners. Turn on and
press in the control knob for the burner with the pressure
gauge fitted.
See the Technical Data section at back of the book for the
correct size. After checking the pressure, turn off the taps and
replace the burner head.
Reassemble burner top, making sure it is reassembled in the
correct way on the burner body.
Check operation of all the burners.
Check the appliance is gas sound.
