Please read these instructions care-
fully before using the boiler.
These instructions are approved for
Alde Compact 3000 92 X, 93X and 94X
boilers fitted in caravans, motor cara-
vans and buildings in accordance with
CE no. 048 AP-0013.
Installation and repairs may only be
carried out by a professional. National
regulations must be adhered to.
BOILER DESIGN
The boiler consists of three eccentri-
cally-fitted cylinders (heat exchanger,
water jacket for the heating system and,
outermost, water jacket for hot water).
The two outer pipes, as well as their
ends and connections, are made from
stainless steel, while the heat exchan-
ger is made from aluminium.
The heat exchanger is divided into two
semi-circles. The burner is located in
the upper half, the combustion cham-
ber, and the combustion gases are
expelled through the lower half. The
burner unit is fitted on the end of the
heat exchanger. It consists of a com-
bustion fan, burner, solenoid valve and
intake/exhaust connections. One or two
heating cartridges are fitted to the water
jacket of the heating system. Output is
2 or 3 kW, depending on model.
DESCRIPTION OF
FUNCTIONS
Using LPG
When the sliding switch on the control
panel is set to LPG, the combustion fan
starts. The fan creates pressure against
the pressure gauge. When the fan pres-
sure is sufficiently high, the pressure
gauge signals the electronics box that
the boiler can be lit. The electronics box
sends ignition sparks to the sparkplug
at the same time as it sends electricity
to the solenoid valves, which open to
allow gas in. The burner ignites, and a
sensor transmits a signal back to the
electronics box that the boiler is lit and
the ignition spark stops. The burner
keeps burning until the boiler thermo-
stat or the room thermostat reaches the
set temperature reading. Should the
boiler go out for any 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 set-
tings on the control panel, the 12-volt
relays on the circuit board trip, allowing
the 230 volt supply to reach the cart-
ridge. The heating cartridge is control-
led 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 switch off the main switch
for the boiler when the vehicle is not
being used.
• 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.
