5. Components having adjustments protected (e.g. paint sealed) by manufacturer are only to be
adjusted by an qualified service agent. They are not to be adjusted by the installation person.
NOTE: Do not obstruct or block the appliances flue. Never directly connect a ventilation
system to the appliance flue outlet.
Clearances
NOTE: Only non-combustible materials can be used in close proximity to this appliance.
Any gas burning appliance requires adequate clearance and ventilation for optimum and trouble-free
operation. The following minimum installation clearances are to be adhered to:
Assembly
This model is delivered completely assembled. Ensure that the legs, rear rollers are securely attached.
NOTE: This appliance is fitted with adjustable feet / rear rollers to enable the appliance to be
positioned securely and level. This should be carried out on completion of the gas
connection. Refer to the ‘Gas Connection’ section.
Gas Connection
NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY AN AUTHORISED PERSON.
1. Cobra Barbeques do not require an electrical connection, as they function on the gas supply only.
2. It is essential that the gas supply is correct for the barbeque to be installed and that adequate supply
pressure and volume is available. The following checks should therefore be made before installation:
a. The Gas Type the appliance has been supplied for is shown on coloured stickers located above the
gas entry point and next to the rating plate. Check that these are correct for the gas supply the
appliance is being installed for. The gas conversion procedure is detailed in the ‘Gas Conversion and
Specification’ section of this manual.
b. The Supply Pressure required for this appliance is shown in the 'Specifications' Section of this
manual. Check the gas supply to ensure that adequate supply pressure exists.
c. The Input Rate of this appliance is shown on the Rating Plate and in the 'Specifications' section of
this manual. The input rate should be checked against the available supply line capacity. Particular
note should be taken if the Barbeque is being added to an existing installation.
NOTE: It is important that adequately sized piping runs directly to the connection joint on the
appliance with as few tees and elbows as possible to give maximum supply volume.
3. Fit the gas regulator supplied, into the gas supply line as close to the appliance as possible.
The regulator connections are ¾" BSP female.
The connection is ¾" BSP male.
(Refer to the ‘Specifications’ section for the gas supply location dimensions).
NOTE: The gas pressure regulator provided with this appliance is convertible between Natural Gas
and LPG and is already converted ex-factory to the gas type labelled beside the gas
connection point. The regulator outlet pressure is fixed ex-factory and it is NOT to be
adjusted.

4. A suitable joining compound which resists the breakdown action of LPG must be used on every gas line
connection, unless compression fittings are used.
NOTE: A manual isolation valve must be fitted to the individual appliance supply line.
5. Correctly locate the appliance into its final operating position and using a spirit level, adjust the legs so
that the unit is level and at the correct height.
6. Connect the gas supply to the appliance.
7. Check gas operating pressure is as shown in 'Specifications' section.
8. Check all gas connections for leakages using soapy water or other gas detecting equipment.
NOTE: The operating pressure to be measured at the
manifold test point and with two burners operating
at the ‘High Flame’ setting.
9. Turn off the mains gas supply and bleed the gas out of the
appliance gas lines.
10. Turn ‘ON' the gas supply and the appliance.
11. Verify the operating pressure remains correct.
WARNING:
CHECK CONNECTIONS FOR LEAKS WITH SOAPY WATER. DO NOT USE A NAKED FLAME.

Operation
Revision 2

Cobra Series Gas Barbeque
Safety System
The purpose of the safety system is to shut off the
flow of gas if the pilot flame goes out. It is
comprised of the flame itself, the thermocouple,
and the flame failure gas valve.
The pilot flame is lit by holding in the gas control
knob, which in turn temporarily pushes the plunger
inside the safety valve open and allows gas to flow
through. Once the burner is lit, the thermocouple
will begin to generate millivolts (after about 10 to
30 seconds of being heated) and will energize the
electromagnet inside the gas valve. Once
energized the electromagnet holds the plunger
inside the gas valve in the open position. The
plunger has to have been pushed all the way in for
the electromagnet to be able to hold it in place. If
the burner flame goes out for some reason, the

referencing of Installation, Operation and Servicing.

System
thermocouple will cool after about 10 to 30
seconds and stop generating millivolts. The
electromagnet will then de-energize, and the
plunger will snap shut, cutting off the flow of gas.
Detail of each component in the safety system is
explained below.
Thermocouple
The thermocouple is a device that generates
electricity when heat is applied to the tip.
The tip of the thermocouple is located in the pilot
burner flame, and the nut at the other end of the
thermocouple screws into the back of the gas
valve. Inside the copper tubing is a wire which is
joined at the tip but insulated from the rest of the
tubing. These two parts (the copper tubing and
wire) make up the "wiring" for an electrical circuit.
When these two dissimilar metals, wire and tip, are
heated an electrical voltage is produced. This type
of thermocouple generates between 7 and 30
millivolts when heated in the pilot flame.

Cobra Series Gas Barbeque
Electromagnetic Flame Failure Gas Valve
The purpose of the safety valve is to shut off the
flow of gas if the pilot flame goes out.
Inside the body of the gas valve is an
electromagnet connected to a spring loaded
plunger. When the electromagnet is energized, it
holds the plunger in, allowing gas to flow through
the valve. When the electromagnet is
de-energized, the plunger snaps to the closed
position, stopping the flow of gas.
Millivolts are provided to the electromagnet by
the thermocouple (not shown) which generates
millivolts when heated. The thermocouple screws
into a fitting at the back of the gas valve to make
an electric connection. By pressing in the gas
control knob, the plunger can be temporarily held
open while lighting.
There are two reasons for this; firstly, gas has to
flow through the safety valve to make it possible
to light the pilot burner, and secondly the plunger
has to be pushed all the way in for the
electromagnet to hold it in. i.e. the
electromagnet is strong enough to hold the
plunger in once there, but is not strong enough
to pull it in by itself.
Sometimes a problem with the flame not staying
lit after releasing the button can be attributed to
not pushing the plunger all the way in.

5.2 Fault Diagnosis
5.2.2 Pilot Drops Out when Gas
Knob Released
Pilot Flame Too Small
If pilot can be lit but the flame is too small to
impinge on the thermocouple, then check the gas
pressure. If pressure is correct, remove the pilot
injector from pilot burner and check for blockages
and / or correct size.
5.2.1 Pilot will not Light
Short in High Tension Lead
If repeated sparking of the piezo shows
intermittent sparking at the electrode, then the
lead should be traced to find area of short. This
can normally be visually seen as the spark arcs.
If the lead is shorting the best solution is to
replace it, as the electrical insulation strength of
the lead may have deteriorated.
If the spark arc can be seen at the electrode
insulator at the pilot burner instead of at the
electrode tip, then the insulator probably has a
fracture and should be replaced.
Piezo Ignitor Faulty
If no spark at all can be generated, remove piezo
ignitor and hold close to cabinet body, depress
piezo ignitor and if a spark cannot be generated
to cabinet body the piezo ignitor is faulty and
should be replaced.
NOTE:
If piezo ignition fails, the pilots can be
manually lit in the interim until the piezo
circuit is repaired. A standard taper torch
or matches / lighter can be used for manual
back-up ignition.
Thermocouple Faulty
Check thermocouple connection to gas control is
firm (loose connections will cause resistance in
millivolt circuit and result in pilot outage).
If connection is OK, then disconnect the
thermocouple from the gas control valve, light
the pilot, and whilst holding the control knob in,
measure voltage between the thermocouple and
earth (e.g. the body of the gas control valve).
This should read approximately 30mV. If this
reading is less than 10mV then the thermocouple
is faulty - replace.
Gas Valve Electromagnet Faulty
If thermocouple millivoltage is above 10mV and
the pilot still will not hold then the gas magnet is
faulty - replace.
