LPG CONVERSION DONG YANG
MODELS WFE912, WFE914 & WFE916
This appliance is supplied set up to for Natural Gas
usage. A conversion kit is included with the product
for Universal LPG usage. The conversion kit contains 6
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 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 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
• 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.
