friendly and does not generate soot on complete com-
bustion. It can be stored in cylinders for any length of
time without its quality deteriorating. LPG is entirely free
of poisonous substances.
The risk with gas is that leaking gas is ignited, resulting
in an explosion. As LPG has no distinct aroma, sulphur
compounds are added that give a distinct, pungent
smell, even when the concentration of gas is as low as
one fifth of the lower explosion limit. The LPG burner
usually works at a lower pressure than the pressure in
the cylinder. Low pressure is obtained by allowing the
LPG to pass through a regulator.

TROuBLESHOOTING
Here is a brief troubleshooting chart that may be of help
in the event of simple faults.
The ignition spark comes but the boiler does
not start
1.
Check gas supply.
2.
Is the service tap fully open?
3.
If the boiler has been out of use for a while or if the
gas cylinder has been changed, it takes longer to
ignite than normal.
4.
The thermostat knob must be pushed down as far as
it will go when starting.
5.
If this does not help, contact your service workshop.
No ignition spark
1.
Check that there is a 12-volt supply to the boiler.
2.
Check the fuse on the boiler is intact.
3.
Check that the warning light for the ignition spark is
flashing.
4.
Remove the lower front cover. Check that the cables
to the ignition transformer (small black box just under
the control panel) and the microswitch (under the
thermostat) are properly attached and that there is no
corrosion on the cable clips.
5.
If this does not help, contact your service workshop.
The boiler ignites but goes out when the ther
mostat knob is released
1.
Repeat the ignition procedure as per instructions in
chapter 2:2 (wait 3 minutes before igniting the boiler
again). Make sure that the thermostat knob is pushed
down as far as it will go and hold it in position for
20-30 seconds after the warning light has gone out.
2.
Check that the pilot flame comes into contact with
the tip of the thermoelement (to the right of the pilot
burner).
3.
If this does not help, contact your service workshop.
The boiler boils
1.
Turn the thermostat knob to 1 (lowest system tem-
perature) and check that the main flame goes out, as
it should.
2.
Check that the sensor is secured correctly. It should
be attached to the body of the boiler by a spring clip
just under the control box with heat-conducting putty
in between.
3.
If this does not help, contact your service workshop.

Vibrations in the circulation pump (12volt)
1.
Release the nut holding the circulation pump.
2.
Turn the pump a little and tighten up the nut again.
3.
Check that the rubber connection between the motor
and the shaft is straight and does not wobble when in
motion.
4.
Check that there is no obstruction in the way of the
pump at the bottom of the expansion vessel.
5.
If this does not help, contact your service workshop.
Circulation pump (12volt) will not start
1.
Check that the slider on the room thermostat is in
"ON" position.
2.
Check that the temperature shown on the room ther-
mostat is higher than inside the caravan.
3.
Check that the changeover switch on the control
panel for the circulation pump is on "12-volt pump".
4.
Remove the circulation pump and check that the ca-
bles are properly secured, and that there is a 12-volt
supply.
5.
If this does not help, contact your service workshop.
Incorrect temperature on the room thermostat
1.
Check by using an accurate thermometer inside the
caravan.
2.
Remove the cover from the room thermostat (press
in the pin on the left-hand side and pull the cover
straight out).
3.
Pull out the knob and move it as many degrees up or
down as it indicated wrongly, and press it into place
again.
4.
Replace the cover and check that the temperature
agrees with the scale on the room thermostat.
The immersion heater has stopped working
1.
Check that there is power (230 volts) in the wall
socket.
2.
Check that the relays on the immersion heater switch
on (a gentle click should be heard).
3.
Check whether the overheating protection has trigg-
ered. If so, press in the button on the side of the
cover.
4.
If this does not help, contact the service workshop.
Insufficient hot water
1.
Check that boiler thermostat is set on maximum
position.
