Commissioning, Conversion from Natural Gas to LPG

15
Commissioning
When the hob has been fully installed it will be necessary
to check the minimum flame setting. To do this, follow
the procedure below.
- Turn the gas tap to the MAX position and ignite.
- Set the gas tap to the MIN flame position then turn
the control knob from MIN to MAX several times. If
the flame is unstable or is extinguished follow the
procedure below.
Procedure:
Re-ignite the burner and set to MIN.
Remove the control knob.
To adjust, use a thin bladed screwdriver and turn
the adjustment screw (see diagram) until the flame
is steady and does not extinguish, when the knob
is turned from MIN to MAX. Repeat this procedure
for all burners.
Pressure Testing
Remove left hand pan support and front left burner
cap and crown.
Fit manometer tube over the injector.
Turn on the burner gas supply and ignite another
burner.
The pressure reading should be nominally 20mbar
and must be between 17 mbar and 25mbar.
Turn off the burner supplies.
Conversion from Natural Gas to
LPG
IMPORTANT
The replacement/conversion of the gas hob should only
be undertaken by a competent person.
It is important to note that this model is designed for use
with natural gas but can be converted for use with butane
or propane gas providing the correct injectors are fitted.
The gas rate is adjusted to suit.
Method
• Ensure that the gas taps are in the 'OFF' position
• Isolate the hob from the electrical supply
• Remove all pan supports, burner caps, rings, crowns
and control knobs.
• With the aid of a 7mm box spanner the burner
injectors can then be unscrewed and replaced by the
appropriate LPG injectors.
TO ADJUST THE GAS RATE
With the aid of a thin bladed screwdriver completely
tighten down the by pass adjustment screw, which is
located down the centre of the gas tap control shaft.
Upon completion stick the replacement rating plate on
the under side of the hob.
