Description Of Functions - Alde Compact 3010 Manuel

OPERATING INSTRUCTIONS COMPACT 3010
Please read these instructions care-
fully before using the boiler.
These instructions are approved for The
Alde Compact 3010 boiler fitted in Rec-
reational Vehicles as detailed in Standard
ANSI 21.13, CSA 4.9.
Installation and repairs may only be car-
ried out by a professional. This boiler
must be installed in accordance with local
codes if any; if not, follow ANSI Z223.1/
NFPA 54 or CAN/CSA B149.1, Natural
Gas and Propane Installation Code, as
applicable.
BOILER DESIGN
The boiler consists of three eccen t rically-
fitted cylinders (heat exchanger, water
jacket for the heating system and, outer-
most, water jacket for hot water).
The two outer pipes, and their ends and
connections, are made of stainless steel,
while the heat exchanger is made of alu-
minium.
The heat exchanger is divided into two
semi-circles. 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 combus-
tion fan, burner, solenoid valve and intake/
exhaust connections.
Two heating elements are fitted to the
water jacket of the heating system. Maxi-
mum output is 1,9 kW.
DESCRIPTION OF
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 ignition sparks to
the sparkplug at the same time as it sends
electricity to the solenoid valve, which
opens to allow the gas in. The burner
ignites, and a sensor transmits a signal
back to the circuit board that the boiler
is lit, and the ignition spark stops. The
burner keeps burning until the boiler ther-
mostat or the room thermostat reaches
the set temperature reading.
Should the boiler go out for any reason,
the sensor is activated and a new attempt
is made to start the boiler (in about 10
seconds).
Using the Heating Element
Electrical operation is selected on the
control panel, the 12-volt relays on the
circuit board activate, allowing the 120 volt
supply to reach the electrical elements.
The heating element is controlled in the
same way as the gas boiler.
Hot Water
When only hot water is required, for
example during the summer, no settings
need to be changed, the boiler will look
after this function automatically.
The pump will only start when the
temperature in the vehicle is lower than
the set temperature (see item 4, Control
Panel).
If the vehicle temperature is higher, the
pump will not start.
! ATTENTION !
IMPORTANT INFORMATION
• The boiler must not be started if
there is no antifreeze in the system.
• The boiler always gives priority to the
electrical heating element.
• The LPG boiler and heating element
may be operated at the same time.
• The heating system may be heated up
without the hot water heater being filled
with fresh water.
• Always switch off the main power for
the boiler when the vehicle is not being
used.
• Always drain the hot water heater of
fresh water if there is a risk of frost
when the heater is not in use.
• The LPG boiler must not be operated
when refuelling the vehicle.
• When washing the vehicle, take care
not to get water in the vent.
THE DOMESTIC HOT
WATER HEATER
The boiler is fitted with a built-in hot
water heater with a volume of approx. 2.5
Gal/8.5-liters fresh water. The hot water
heater can produce around 3 Gal/12 liters
of 104°F/40°C water per half-hour (at a
cold water temperature of 50°F/10°C). If
the heating elements are used instead of
gas for heating the boiler, the capacity is
slightly reduced.
Always rinse out the heater before it is
used, particularly if it has not been in
operation for some time.
ATTENTION! The hot water is not
intended for drinking or cooking. When the
heater is in continuous use, it should be
emptied approx. once a month, to ensure
that a new air cushion is formed in the
heater.
The air cushion is essential for absorbing
pressure surges in the heater. For emp-
tying specially-adapted boilers, as well
as any other freshwater systems in the
vehicle, please refer to the manufacturer's
instructions.
ATTENTION! The hot water heater
should always be drained of fresh
water when there is a risk of freez-
ing and when the recreational vehicle
is not in use. The warranty does not
cover frost damage.
Draining the heater using the com-
bined safety/drain valve:
1. Switch off the freshwater pump
2. Open all water taps.
3. Then open the safety/drain valve by
turning the knob (K) 180°.
4. The heater will now drain directly below
the vehicle through the safety/ drain
valve hose. Check that all the water is
emptied out (about 2-3Gal/7-10 litres).
Leave the valve in the open position
until the next time the heater is used.
5. ATTENTION! Check that the automatic
check valve (N) is open and is allow-
ing air to enter the heater when it is
being drained, and that the hose is not
blocked.

THE HEATING ELEMENTS
All Compact 3010s are fitted with two
120 V heating elements with a maximum
output of 950 W each. Select the heating
element output on the control panel.
Always check that the input breaker of the
vehicle has the correct amperage in
relation to the selected output. Note these
ratings are for the boiler only.
950 W requires a 10 amp breaker.
THE CIRCULATION PUMP
A circulation pump is required to circulate
the heated glycol fluid/antifreeze. A 12 V
pump are fitted on the boiler.
The control panel's room thermostat is
used to control the circulation pump, i.e.
switching on or off, depending on the
heating requirement.
