Operating instructions
Plug the power cord into the wall socket and turn on the
power to the heater (see figure 3).
Alternatively, switch on the isolation switch
and circuit breaker at the main switchboard if the heater has
fixed wiring.
Refrain from using an
extension cord.

When there is power available to the heater and
it is in the OFF or Standby mode, a red LED
located inside the ON/OFF button will flash
twice and will extinguish for approximately 3
seconds and then repeat this cycle
continuously.
?
To turn the heater ON press the ON/OFF button
once.
?
The LED will illuminate and stay lit but there will
be approximately 5 seconds delay before the
ignition system commences. On successful
ignition the heater will operate on Low Fire and
Low Fan for approximately 3 minutes then will
switch to selected setting (if already chosen).
?
The LED will extinguish approximately 30
seconds following the ignition startup.
?
Select the desired Heating level by pressing the
LOW, MEDIUM or HIGH button once as
required.
?
LOW is LOW heat and LOW speed fan. HIGH is
HIGH heat and HIGH speed fan.
?
To turn the heater OFF press the ON/OFF
button once. The burner will extinguish but the
fan will continue to operate for approximately 3
minutes.
?
If the Ignition system fails to ignite or keep the
burner alight, press the ON/OFF button once to
turn off the heater. Wait at least 20 seconds
before attempting to turn the heater on again.
Remember that the fan will continue to operate
for approximately 3 minutes after the OFF
button has been pressed but you can turn the
heater ON again without having to wait for the
fan to stop operating.
?
If there is an interruption to the power supply
the heater will fail safely and switch off. When
the power supply has been restored adopt the
20 seconds waiting rule before turning the
heater ON.

flame then extinguishes
after 10 seconds.
Continues to spark
while flame present.
11 Appliance lights but
goes into lockout
12 Fuse blowing.
13 Heater will not start, no
indicator lamps.
?
The gas valve should open at the same time as the igniter
sparks. If there is no gas to the burner when this occurs
check the solenoid coils for continuity.
?
Check that the gas pressure is present at the test point
when the spark is being generated.
?
Check that there is gas to the inlet of the gas control.
?
Test the flame for correct ionisation signal.
Connect a multimeter in series with the flame rod and set
the function to measure micro-amps.
The module will go into lockout if the flame current
sensitivity is less than 0.5 micro-amps.
The approximate signal strength on high flame is about 10
micro-amps and on low 4 micro-amps.
The signal strength will fluctuate but should be greater
than 1.5 micro-amps at all times.
Take precautions because the ionisation probe can
have a high negative voltage and can cause a shock.
?
If the fuse continues to blow check the solenoid coils for a
signs of them being shorted.
?
Check the fan and wiring for short circuit.
?
Check that the electricity supply is correct. If Nuetral /
Active are incorrectly connected the control module will
not function.
FIG 28.
?
Check that the wall socket to the appliance has correct
polarity. Do not use an extension cord.
?
Check polarity in the electrical supply lead to appliance.
?
Check that the sense electrode is in flame.
?
Check that the appliance is earthed correctly. A check
between the earth pin on the plug and an unpainted part of
the appliance should see a resistance of 0.1 ohms.
TROUBLESHOOTING
5 Confirm spark is produced
when heater is turned on.
6 If no spark being produced.
8 Spark is being produced
but not at the burner.
A blue spark can be seen when the heater ignition process
starts. Ensure spark is present between electrode and burner.
Listen for cracking sound. The spark is
misdirected.
Check the spark ceramic insulator for signs of
cracks.
Check that the spark lead is connected into the
module.
Check the continuity of the
ht
cable.
Check that there is no short circuit to earth and
spark gap is correct.
(see fig 35.)
A positive check is to use a jumper wire, connect
one end of the earth and hold the other end
with insulated pliers 4 mm from the spark
generator on the module. If there is no spark to
Earth then change the module.
