LPG CONVERSION DONG YANG – IMPORTANT
(MODELS WFE512, WFE614, WFE612 AND WFE616 ONLY)
This appliance is fitted with Natural Gas burner injectors.
Please follow the procedure below if a conversion to suit
UNIVERSAL LPG is required.
The conversion kit contains 5 injectors and 1 LPG sticker.
1. Remove the hotplate burners to access the hotplate
injectors. Replace the factory fitted NG injectors with
the appropriate injectors, as supplied.
2. Unscrew the hex nut from the regulator. The hex
nut, brass washer and nylon insert will disengage
as an assembly.
3. Unclip the nylon insert from the nut assembly by
rotating the insert 1/4 turn, and pulling it free.
4. Turn over the insert, and clip back into position.
5. Refit the hex nut assembly to the regulator ensuring
that it is fully screwed down. The regulator is now set
for connection to LPG.
6. Turn on the gas supply and at each new connection
check for leaks using soapy water: each hotplate
valve should be turned on, one at a time, and the
injector hole blocked off for several seconds.
7. The operation of the regulator can be confirmed by
connecting a manometer to the pressure test point
located on the side of the regulator body adjacent
to the outlet. With the appliance operating check the
outlet pressure:
• When all burners of the appliance are operating
at maximum,
• When the smallest burner of the appliance is
operating at minimum.
Under these conditions the outlet pressure should not
vary from the nominal outlet pressure of 2.60kPa by
more than ±0.52kPa.
8. If the regulator appears to not be performing
satisfactorily then check the following points:
• If the outlet pressure is consistently too low then
the inlet pressure may be too low and
adjustment of an upstream regulator may be
needed, or an upstream regulator or valve with
insufficient flow capacity may be present in
the gas supply line. If this is suspected then it
may be necessary to repeat the checks whilst
measuring both the inlet and outlet pressure to
determine if the inlet pressure is in the range
2.75 – 7.00kPa.
• Check that the insert has been fitted correctly.
• Check that the turret screw is fully screwed down.
• Check that the regulator has been fitted to
the gas supply line in the correct orientation,
the arrow on the base of the body indicates the
direction of gas flow.
Once these checks have been completed, if the
regulator still fails to perform in a satisfactory manner
it should be replaced.
9. One by one, turn the knobs to minimum and screw
in the bypass screw (accessible when the knob is
removed) until a small stable flame results. Turn the
knob to maximum and then back to minimum to
ensure that the correct minimum flame is maintained.
10. Attach the LPG sticker to the cooker, near the gas
supply inlet. Cover the Natural Gas label that is
factory fitted.

LPG CONVERSION CHANT – IMPORTANT
(MODELS WFE512, WFE614 AND WFE612 AND WFE616 ONLY)
This appliance is supplied set up for Natural Gas usage.
A conversion kit is included with the product for Universal
LPG usage. The conversion kit contains 5 injectors and 1 LPG
sticker.
Please follow the procedure below if a conversion to suit
UNIVERSAL LPG is required:
1. Remove the hotplate trivets, burner caps and burner
crowns to access the hotplate injectors. Replace the
factory fitted injectors with the appropriate injectors, as
supplied. Refer to injector orifice table for injector sizes.
The injector size is stamped on the side of the injector.
2. Unscrew the top hat nut from the regulator. The top hat
nut and control pressure spring assembly will disengage
as an assembly.
3. Unscrew the threaded pin from top hat.
4. Upturn threaded pin, so spring is free and screw pin
back into the top hat until firm.
5. Refit the top hat nut assembly to the regulator ensuring
that it is fully screwed down. The regulator is now set
for connection to LPG.
6. Turn on the gas supply and at each new connection
check for leaks using soapy water. Each hotplate valve
should be turned on, one at a time, and the injector hole
blanked off for several seconds.
7. The operation of the regulator can be confirmed by
connecting a manometer to the pressure test point
located on the side of the regulator body adjacent to
the outlet.
With the appliance operating check the outlet pressure:
