3.4 Explanation of the Control
System
Safety System
The purpose of the safety system is to shut off the
flow of gas if the main flame goes out. It
comprises the flame itself, the thermocouple, and
the flame failure gas valve.
The main flame is lit by rotating the gas control
knob anti-clockwise and holding in, which in turn
temporarily pushes the plunger inside the safety
valve open and allows gas to flow through. The
main burner is then lit manually. 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 be pushed all the way
in for the electromagnet to be able to hold it in
place. If the main burner flame goes out for some
reason, the 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
to the main burner.
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 main
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 main flame.

Revision 3
Moffat Cobra Series CS9 - Gas Salamander
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's two reasons for this;
gas has to flow through the safety valve to make
it possible to light the main burner, and secondly
the plunger has to be pushed all the way in for
the electromagnet to hold it in. i.e. the electro-
magnet 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
the plunger not being pushed all the way in.
Electromagnetic Flame Failure Gas Valve
The purpose of the safety valve is to shut off the
flow of gas if the main flame goes out.
Inside the body of the gas valve is an electro-
magnet 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 to the main burner.

5.2 Fault Diagnosis
5.2.1 Burner Drops Out When Gas
Knob Released
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 rear of the gas control,
light the burner, and whilst holding the control
knob in, and measure voltage between the
thermocouple and earth (e.g. the body of the gas
control). This should read approximately 30mV.
If this reading is less than 10mV then the
thermocouple is faulty—replace.
Gas Valve Electromagnet Faulty
If thermocouple milli-voltage is above 10mV, and
the burner still will not hold, then the gas electro-
magnet is faulty - replace.
5.2.2 Burner Popping / Blow Back
Gas Leak in Main Burner Plaque
With the burner operating, check for hairline
cracks on the burner tiles (these will appear as
brighter orange lines on the burner tiles). If
visible, replace the main burner.
