Commissioning; Conversion From Natural Gas To Lpg - Zanussi GAS HOB ZGF 982 Instruction Booklet

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, insert a thin
bladed screwdriver down the centre of the
gas tap control shaft and turn the adjustment
screw 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

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.
IMPORTANT
The replacement/conversion of the gas hob should
only be undertaken by a competent person.
