Bailey Approach Advance - Alde Heating System

ALDE HEATING SYSTEM
The Alde System is tted in all Autograph
models.
!
Always replace the heat transfer uid
(HTF) in accordance with the
antifreeze product’s lifespan. If in any
doubt, replace the HTF after 2 years.
The corrosion inhibitors found in ethylene
glycol antifreeze may not be cross-compatible.
When topping up or replacing the HTF, ensure
the new antifreeze is compatible with the
current antifreeze product. Read the product
label or contact the product manufacturer for
details.

EfciencyBoiler
!
Alde can accept no liability
whatsoever for damage or injury
resulting from failure to observe these
instructions.
Specied Use
These instructions are approved for the Alde
3020 Compact HE boiler tted in caravans,
motorhomes or buildings in accordance with
CE 0402 no. SC0653-13, and have the E5 mark
for installation in vehicles in accordance with
ECE R122, no. 00 001 and R10, no. 04 166, for
use in central heating and hot water systems.
The boiler is not intended for use by persons
(including children) with reduced physical,
sensory or mental capabilities, or lack of
experience and/or knowledge, unless they
have been given instruction or are supervised.
The term “specied use” also covers
observance of the operating and installation
instructions.
The Alde 3020 Compact HE boiler must be
installed or repaired by a competent person in
accordance with current local regulations.
In the unlikely event that your boiler develops
a fault, switch off the boiler and contact Alde,
or your dealer or installer.
Operating and installation instructions for the
Alde control panel are supplied separately.
The owner is always responsible for
maintenance and arranging inspection.
Boiler Design
The boiler’s internal heat exchanger consists
of three concentric cylinders: the combustion
chamber, the central heating cylinder and the
hot water cylinder.
The combustion chamber is made from
aluminium, and is divided into two halves by
a bafe plate, with the burner head located in
the top half, and the ue gases venting through
the bottom half.
The combustion assembly is xed to the end of
the internal heat exchanger. It consists of the
burner, combustion fan, gas valve, air intake
and exhaust ducts, and gas line.
Two electric heating elements are sealed
inside the central heating cylinder, one for 1kW,
one for 2kW.
Description of Functions
Gas Heating
When gas heating is set to “On” the combustion
fan starts to revolve. Once the correct speed is
achieved (in rpm), a signal is sent to the PCB
(Printed Circuit Board) for the burner to be
lit. The gas valve opens, passing gas, and the
ignition module on the PCB generates sparks
at the electrode on the burner head.
When the burner ignites, a ame supervision
device (FSD) signals the ignition module to
cease sparking. The burner res until the
boiler or room thermostat reach the set-point.
Should the burner ame out unexpectedly, the
FSD detects this and attempts to reignite (for
about 10 seconds), before shutting down and
raising a fault code.
i
Listen carefully to the ignition
sequence of the boiler. You should hear
the whirl of the combustion fan, the
clunk of the gas valve and the tick-tick
of the ignition module.
Electric Heating
When electric heating is set to 1, 2 or 3kW,
relays on the PCB trip, feeding the 230 v
supply to the electric heating elements. These
are controlled by the same programme as the
gas heating.
Domestic Hot Water
The combi-type boiler automatically produces
hot water. Heat is emitted from the central
heating cylinder into the hot water cylinder.
If the hot water cylinder is empty, the air is
heated but no damage can result.
i
In a good summer, for example, lower
the desired temperature on the
control panel to around 10°C. The
central heating will not circulate
(unless the temperature drops to
10°C), but you will still have hot water
