For information and requirements about construction and
capacity of consumer piping refer to AS5601 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
AS5601, 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.
This appliance is supplied set up for Natural Gas usage.
• 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.

LPG CONVERSION MODEL EFEP915
A conversion kit is included with the product for Universal
LPG usage. The conversion kit contains 10 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:
• 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.
