Starting the LPG boiler2:2
Open the regulator and service tap for the LPG.1.
Turn the thermostat knob to ignition position (see 2.
g 2). The indicator light for the ignition spark starts
ashing.
Press the thermostat knob down as far as it will go. 3.
Hold it down for about 15 seconds after the indicator
light has gone out. (The boiler has ignited as soon as
the warning light goes out, but in order for the ignition
safety cut-out to remain open, the thermostat knob
must be held down for the necessary period).
Release the thermostat knob.4.
Turn it to operating position and set the desired tem-5.
perature (see chpt 2:4).
If the indicator light starts ashing immediately after 6.
the thermostat knob has been released the boiler has
not ignited. Press the thermostat knob down again
and repeat the starting procedure as above, but hold
it down a little longer.
You can also check through the window in the lower 7.
front plate whether the boiler is lit.
Should the boiler go out, turn the thermostat knob to
stop position (see g 3). Wait 3 minutes and repeat the
starting procedure.
The boiler is equipped with automatic reignition, which
means that if it goes out for some reason, it attempts
to restart for about 20 seconds (until the safety cut-out
has cut the gas supply). Should the gas run out while
the boiler is in operation, the warning light will start
ashing and continue on until the boiler is shut down or
restarted.
Shutting down the LPG boiler2:3
Turn the thermostat knob clockwise to stop position 1.
(see g 3). After about 20 seconds, a click should
be heard from the gas valve, which means that the
safety cut-out has closed.
Stop the circulation pump on the control panel.2.
Close the service tap for the LPG.3.
NB. When the boiler has gone out, it must not be
reignited until 3 minutes have elapsed.
Setting for maximum comfort2:4
For maximum comfort and economy, it is important to
set the right water temperature in the system. At low
outside temperatures, a higher water temperature is
required than at more normal temperatures. The ideal
setting on the thermostat knob is when the circulation
pump runs about 75% of the time.
When heating a very cold boiler, the thermostat knob
should not be set to maximum temperature imediately,
but at an intermediate position for the rst 10 minutes.
The various gures on the thermostat knob represent
the number of degrees of the water temperature in the
boiler as per g 4.
When it is extremely cold, the gas boiler and the immer-
sion heater can be run at the same time. This means
that maximum power is obtained from the heating
system.
When the heating system is used at a high altitude, the
boiling point of the liquid mixture changes. In this case
the system temperature should be lowered as per g 5.
In order to utilize the principle of water-born heat in the
best possible way, it is important that air can pass freely
under beds and behind back cushions. If the caravan
has a tted carpet, for example, ensure that the carpet
does not cover the intake hole for the convectors. It is
equally important that the cushions and blankets do not
prevent air circulation behind the back cushions.
Setting the room temperature2:5
The temperature required inside the caravan should be
set on the knob of the room thermostat, which is gradu-
ated between 5 and 30 °C.
Circulation pump2:6
In order to make the heated glycol water circulate, some
form of pump is required. In the expansion vessel of the
LPG boiler a 12-volt circulation pump is tted as stand-
ard. The boiler can also be equipped with an immersion
heater with a 230-volt circulation pump. The choice of
which pump to use, and whether it is to run constantly or
be interrupted by the room thermostat, is made on the
boiler’s control panel.
Electrical heating2:7
If the immersion heater is tted on the boiler it can only
be used if you have access to 230 volts ~. The power
output is 1000 and 2000 watts respectively. Choice of
power is made on the boiler’s control panel.
Inside the immersion heater’s protective cover, there
are two thermostats. One ensures that the immersion
heater maintains an operating temperature of around 80
°
C while the other acts as overheating protection, which
cuts the current automatically if the immersion heater
boils for some reason. If the overheating protection trig-
gers, it can be reset by pressing in the overheat reset
button on the side of the immersion heater (see g 6A).
Make sure that textiles and other inammable material
cannot come into contact with the immersion heater.
NB. All electrical work on the immersion heater must
be performed by an authorized person.
EXTERNAL START3.
(applies only if the immersion heater is tted).
Do you want the caravan to be heated when you arrive?
If so, your neighbour or the warden can start the heat-
ing without having to enter the caravan. However, your
boiler must be tted with an immersion heater and there
must be a battery eliminator (art. no. 2921 520) con-
nected to the boiler.
How to perform an external start:
Plug the battery eliminator into a 230-volt socket.1.
Plug the 12-volt contact into the power intake on the 2.
boiler’s control panel (see g 1 J).
Select power and circulation pump on the control 3.
panel.
Switch off the main switch in the caravan.4.
