LPG conversion models EFEP916
A conversion kit is included with the product for Universal LPG usage.
The conversion kit contains 5 or 7 injectors (refer to LPG conversion
table) 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:
• 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.

For information and requirements about construction and capacity
of consumer piping refer to AS/NZS 5601 series of standards.
Gas connection
Read these points before connecting to the gas supply:
•
The appliance is preset for natural gas use. If LPG is
to be used see Conversion to LPG section.
•
Gas installation must be made in accordance with AS/NZS 5601,
the local gas fitting regulations, municipal codes and other
statutory regulations.
•
The gas connection point is a ½” BSP external thread located at
the rear of the appliance as shown.
•
A regulator is supplied which must be fitted to the appliance.
Ensure that when fitted the pressure test point of regulator is
accessible.
•
The regulator is to be fitted to the manifold inlet at the rear of the
appliance and the connection thread is sealed using a tape or
jointing compound suitable for gas connections. The consumer
piping is then connected to the inlet of the regulator, either:
1
directly, or
2
using a hose assembly and in accordance with Clause
6.10.1.9 of AS 5601.1 (High level connection) together with
the supplied elbow. The elbow is fitted to the inlet of
the regulator and oriented to allow the hose to hang
downwards. The connection thread between the regulator
and elbow is sealed using a tape or jointing compound
suitable for gas connections.
