reason, the sensor is activated and the
electronics box ensures that a new attempt is
made to start the boiler (in about 10
seconds).
Using the heating cartridge
When the heating cartridge sliding switch is
set to any of the output settings on the
control panel, the 12-volt relays on the circuit
board trip, allowing the 230-volt supply to
reach the cartridge. The heating cartridge is
controlled in the same way as the gas boiler.
IMPORTANT INFORMATION
- The LPG boiler and heating cartridge may
be operated in parallel.
- The heating system may be heated up
without the warm water heater being filled
with fresh water.
- Always drain the warm water heater of
fresh water if there is a risk of frost.
- The LPG boiler must not be operated
when filling the vehicle with fuel, in a
garage or elsewhere.
- The boiler must not be started if there is
no glycol in the system.
Note: If heating is to be operational
whilst unattended, ensure mains hook
up is connected. System can cause
battery to run flat, if battery is the sole
power source.
THE CONTROL PANEL
The boiler is controlled using sliding switches
on the control panel. The desired temp-
erature in the vehicle is set and regulated via
the thermostat on the control panel.
Control panel functions:
A. Heating cartridge switched off.
B. Heating cartridge switched on at 1050 W.
C. Heating cartridge switched on at 2100 W.
D. Heating cartridge switched on at 3150W
(if the boiler is fitted with this output
setting).
E. LPG boiler switched off.
F. LPG boiler switched on.
G. LED indicates that the LPG boiler is in
blocking mode (the burner has not
ignited, or has gone out for some reason).
H. Warm water setting. The circulation pump
switched off. The heating cartridge/LPG
boiler is operated by the boiler's built-in
thermostat. Used when only hot water is
wanted.
I. Normal setting. The circulation pump is
switched on and is controlled by the
thermostat on the control panel. The
operation of the heating cartridge/LPG
boiler is controlled by the boiler's built-in
thermostat. Used when both heating and
warm water is wanted.
J. Permanent setting. The circulation pump
is switched on and runs constantly. The
Fitted Equipment
thermostat on the control panel controls
the operation of the heating cartridge/LPG
boiler. This setting is used in particular
circumstances, mostly during the winter.
Provides an even flow of heat, but also
reduces the hot water capacity.
K. Knob for setting the desired room
temperature.
L. Index marking for a room temperature of
approx. 22°C.

ABOUT LPS
The properties of LPG
LPG is a petroleum product, formally known
as 'liquid petroleum gas'. It is mainly made
up of propane and butane gas. The
advantage of propane is that it remains
gaseous at temperatures as low as -40∞,
while butane loses effectiveness at +10∞C.
For this reason, propane is used in colder
countries. The cylinders contain LPG both in
liquid and gaseous form. Then the cylinders
are filled, the pressure turns the gas into
liquid. When the cylinder valve is opened,
the LPG becomes a gas again. The risk
involved in using LPG is that any leaking gas
may ignite and explode. Since LPG is
heavier than air, any leaking gas will collect at
the lowest point.
LPG contains no toxic substances but
breathing in concentrated gas may have a
certain anaesthetising effect, and can also
