Westinghouse GHP17S - Manual (Page 12)

CAUTION
This a ppliance is fitted with Natural Gas burner injectors.
Please follow the procedure below if a conversion to suit
LP gas is required.
The conversion kit contains appropriate LPG injectors and
1 LPG sticker.
To convert to LPG
1. Remove the hotplate burners to access the hotplate
injectors. Replace the factory fitted NG injectors with
the appropriate injectors, as supplied (see Table 2).
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 ¼ 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 LP.
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 as
per diagram figure 10. Check that the hex nut 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 – refer figure 12) 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.
