Boiler Design; Description Of Functions - Alde Compact 3010 Operating Instruction & Installation Instruction

user and instaLLation instruCtion
please read these instructions
carefully before using the boiler.
These instructions are approved for the
Alde Compact 3010 boiler fitted in boats
of up to 24 m in length in accordance
with CE no. 0845 BP­0003 and
EMC e5 03 0261.
Installation and repairs may only be car­
ried out by a professional. All national
regulations and codes of practice must
be adhered to and due regard given
to British and ISO standards for boat
building and installations.

boiLer design

The boiler consists of three eccentri­
cally-fitted cylinders (heat exchanger,
water jacket for the heating system
and, outermost, water jacket for warm
water).
The two outer pipes, and their ends
and connections, are made of stainless
steel, while the heat exchanger is made
of aluminium.
The heat exchanger is divided into two
semi­circles. The burner is located in
the upper half, being the combustion
chamber, 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
combustion fan, burner, solenoid valve
and intake/exhaust connections.
Two heating cartridges are fitted to the
water jacket of the heating system.
Maximum output is 2 or 3kw, depending
on model.

FunCtions
using Lpg
When LPG operation is selected on
the control panel, the combustion fan
starts. When the fan speed is correct, it
signals the circuit board that the boiler
can be lit. The circuit board sends igni­
tion sparks to the sparkplug at the same
time as it sends electricity to the sole­
noid valve, which opens to allow gas in.
The burner ignites, and a sensor trans­
mits a signal back to the circuit board
that the boiler is lit, and the ignition
spark stops. The burner keeps burning
until the boiler thermostat or the cabin
thermostat reaches the set temperature
reading.
Should the boiler go out for any rea­
son, the sensor is activated and a new
attempt is made to start the boiler (in
about 10 seconds).
using the heating cartridge
Electrical operation is selected on the
control panel, the 12­volt relays on the
circuit board trip, allowing the 230 volt
supply to reach the electrical elements.
The heating cartridge is controlled in
the same way as the gas boiler.
Warm water
When only warm water is required, for
example, during the summer, no set­
tings need to be made, the boiler looks
after this function automatically.
The central heating pump will only start
when the temperature in the boat is
lower than the set temperature (see
item 4, control panel).
If the temperature in the boat is higher,
the pump will not start.
important inFormation
• The LPG boiler and heating cartridge
may be can be operated at the same
time.
• The boiler always gives priority to the
electrical heating cartridge.
• The heating system may be heated
up without the warm water heater
being filled with fresh water.
• Always switch off the main isolator for
the boiler when the boat 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 refuelling the boat.
• The boiler must not be started if there
is no glycol in the system.
• When washing the boat, take care not
to get water in the roof vent.
• Copper should not be used in the
heating circuit.
