Alde Compact 3020
!WARNING: Alde can accept no liability
whatsoever for damage or injury resulting
from failure to observe these instructions.
Specific Use
These instructions are approved for the Alde
3020 Compact HE boiler fitted 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 “specified 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 baffle plate, with the burner head located
in the top half, and the flue gases venting
through the bottom half.
The combustion assembly is fixed to the end
of the internal heat exchanger. It consists of

FITTED EQUIPMENT
105
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 1 kW, one
for 2 kW.
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
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 flame supervision
device signals the ignition module to cease
sparking. The burner fires until the boiler or
room thermostat reach the setpoint.
Should the burner flame cut out unexpectedly,
the FSD detects this and attempts to reignite
(for about 10 seconds), before shutting down
and raising a fault code.
Note: 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 3 kW,
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.
Note: 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.
!WARNING:
• The boiler must not be switched on if
there is no heat transfer fluid (HTF) in the
system.
• Always drain down the freshwater system
if there is risk of frost; in winter, for
example. You may continue to use the
boiler with no freshwater in the system, as
required; no damage can result
• Always replace the HTF in accordance
with the antifreeze product’s lifespan. If in
any doubt, replace the HTF after 2 years.
• Only sterilise the freshwater system with a
product suitable for stainless steel.
• Do not place stowage in the boiler
compartment.
• Do not position awnings, tents or other
enclosures around the flue terminal.
• Do not obstruct the flue. Be careful not to
flood the flue when washing the vehicle.
• The gas heating must not be used when
refuelling the vehicle at the service station
or related facility.
Domestic Hot Water
Being a combi-type boiler, the Alde 3020
Compact HE has an integrated, stainless steel
hot water cylinder that holds approximately 8.4
litres of freshwater.
The boiler can produce around 12 litres of
40°C warm water per 30 mins (at a cold
water temperature of 10 °C). If only the
electric heating is used, this capacity is slightly
reduced.
The hot water should not be used for drinking
or cooking.
Always flush out the hot water cylinder before
use, especially when it has stood empty for
some time. Any steriliser products should
be suitable for use with stainless steel.
Avoid steriliser products containing sodium
hyperchlorite, for example, as these will cause
severe corrosion damage to the hot water
cylinder. Read the product label or contact the
product manufacturer for details.

FITTED EQUIPMENT
106
ALDE HEATING OPERATING INSTRUCTIONS
When the hot water cylinder is in continuous
use, it should be drained and refilled once a
month. This recreates the air cushion in the hot
water cylinder that absorbs pressure surges.
Tip! If continuously using the hot water
cylinder in a hard water area, fit an inline scale
inhibitor to minimise the effects of limescale
Target hot water temperature is greater
than 50 °C in normal operation, to prevent
the growth of Legionella. Over 50 °C , the
hot water will be heated to the maximum
achievable temperature at the time. This
allows the hot water to achieve disinfection
temperatures, and increases warm water
performance.
If scalding hot water temperatures are a
concern – such as with the young, elderly or
infirm – thermostatic mixing valves (TMVs)
can be fitted, and may be required by local
regulations.
!WARNING: Always drain down and
completely empty the hot water cylinder
when there is risk of frost, unless the vehicle
is explicitly stated to be self-winterising by
the vehicle manufacturer.
Failure to drain the hot water cylinder when
there is a risk of frost may result in frost
damage, and is not covered under warranty.
Draining Freshwater
1. Switch off the water pump.
2. Open all water taps, showers, etc.
3. Open the safety/drain valve by lifting the
yellow tab (Fig 1 [M]), or by turning the blue
knob (Fig 1 [K]) 90°.
4. The system will drain directly below the
vehicle through the clear plastic hose on the
safety/drain valve. Check that all water has
emptied out (7–10 litres). Leave the valve in the
open position until the next time the hot water
cylinder is used.
NB: Check that the red breather valve (Fig
1[N]) is allowing air to enter the hot water
cylinder, when it is being drained, and that the
clear plastic hose is not obstructed.
Open the manual safety/drain valve

Heat Transfer Fluid
The central heating system is filled with heat
transfer fluid (HTF), a solution of 50% ethylene
glycol antifreeze and 50% water.
The antifreeze manufacturer will have a
maximum water hardness recommendation.
Read the product label or contact the product
manufacturer for details.
Note: Alde recommends antifreeze meeting
VAG G12++ or G13 specification, and
deionised water (0 ppm).
50:50 ethylene glycol antifreeze and water
will protect against frost down to -35–37 °C.
A refractometer and/or hydrometer can be
used to measure the strength of the antifreeze
solution.
Corrosion protection will vary depending on
the lifespan of the antifreeze. Read the product
label or contact the product manufacturer for
details.
!WARNING: Always replace the 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.
!WARNING: As a rough guideline,
blue and red antifreeze products are not
compatible with each other, but VAG G12++
and G13 spec antifreeze (purple/magenta) is
compatible with both.
Failure to fill with suitable HTF may result in
severe damage to your Alde system, and is
not covered under warranty.
Filling
The central heating system is filled with HTF
through the expansion tank, either by hand, or
using the Alde service pump. Any containers
used for handling or storing the HTF should
be checked first, and must be visibly clean
to avoid introducing contaminants or foreign
objects into the system.
Alde recommends using the Alde 1900-811 or
839 twin-motor service pump to fill the system.
To fill the system by hand, unscrew the
expansion tank cap (Fig 2 [R]), and lift the
circulation pump (Fig 2 [S]) out of the tank (if
applicable). Carefully pour the HTF into the
tank, and repeat until the fluid level is about 1
cm above the MIN mark when cold.
Figure 2

FITTED EQUIPMENT
108
Draining
A drain is fitted in the central heating system,
to allow draining of the HTF. Because the pipes
step up and down, some HTF will be left in the
system after draining. Contact an Alde certified
agent to drain and refill your system.
Central Heating
The boiler is set to an upper limit temperature
of 85°C, i.e., the temperature of the heat
transfer fluid (HTF) as it circulates around the
pipes, radiators, convectors, et al.
To ensure the best performance from hydronic
heating, air must be able to circulate freely
around the back of the furniture (Fig 3). Air
vents, cut into the top and bottom of the
furniture must be unobstructed by carpets,
cushions, or stowage, etc.
The full length of a convector should be
ventilated for best performance.
Note: Use gas and electric heating
simultaneously for the best performance.
The boiler will only use as much energy as is
needed, and is 93% efficient on a SEBDUK
based test.
Figure 3
Bleeding Air
The HTF will contain some air. This is
unavoidable. Air bubbles can also be
introduced when the system in filled.
In a newly-filled central heating system, you
will need to bleed air from the bleed points
to ensure best performance. There is an
automatic air bleed valve on the boiler. There is
also an air vent on the expansion tank.
Bleed points are installed at strategic points
within the system to allow any trapped air to
be bled off
Note: Contact the dealer or installer for
details on where the bleed points are in your
system, and how to access them.
To bleed the system, set the desired
temperature to 30°C and select gas heating on
the control panel.
Set the 12 V inline circulation pump on the side
of the boiler to speed 5 (Fig 1 [D]),by turning
the blue speed dial clockwise, on the face of
the pump motor. NB: Speed is not adjustable
if using the 12 V circulation pump fitted in the
expansion tank.
After 10 mins, set the pump back to its
normal running speed (2 for a caravan, 3 for
a motorhome).
Now power off the Alde 3020 Compact
HE boiler completely, making sure that the
circulation pump is not active.
Follow the flow pipe from the boiler, and bleed
the system at each bleed point.
If Alde bleed points have been fitted, these are
metal bleed screws mounted on black EPDM
rubber connectors (Fig 4). Have a cloth in
hand. To open, turn the screw anticlockwise
between thumb and forefinger. Air will hiss out.
When fluid trickles out, closethe bleed screw
and mop up fluid with the cloth.
ALDE HEATING OPERATING INSTRUCTIONS

FITTED EQUIPMENT
109
Move on to the next bleed point and repeat,
until all bleed points have been tended to.
Air Lock
If enough trapped air accumulates at one
point, an air lock can result and prevent the
circulation of hydronic heating.
A ramp or steep slope can be used to raise
one end of the vehicle, causing the trapped
air to shift around the system. Repeat the full
bleed procedure. A caravan can be slowly and
carefully tilted to reproduce this effect.
To clear a stubborn air lock in under 15
minutes, an Alde-certified service agent can
use the Alde 1900-811 or 839 twin-motor
service pump.
230 V ELECTRIC
The Alde 3020 Compact HE boiler has two
230 V electric heating elements, outputting
1050 W and 2100 W, or 3150 W combined,
and drawing 5 A, 9 A, and 14 A respectively
(rounded).
230 V breakers, fuses, fused spurs and
isolator switches should be rated for 16 A.
Before using electric heating, check the
current limit on the electric supply you are
hooking up to.
• 6 A limit, only use 1 kW electric heating.
• 10 A limit, use 1–2 kW electric heating.
• 16 A limit, use 1–3 kW electric heating.
NB: If the electric supply has unstable voltage,
the amperage will also fluctuate.
LPG
LPG (liquefied petroleum gas) has two main
variants, propane and butane gas. The gas
heating in your Alde 3020 Compact boiler can
use propane or butane gas as fuel. Many LPG
fuels contain a mixture of propane, butane and
other additives.
BS 5482 Part 1 states, “For butane cylinders,
satisfactory service might not be obtained at
temperatures of less than 10 °C; the most
suitable temperature range is from 13 to 30
°C. For temperatures less than 13 °C, the use
of propane should be considered.”
For this reason, Alde recommends using
propane gas for all year round gas heating.
LPG cylinders contain both gas and liquid
forms. When the cylinder is filled, high pressure
transforms the gas into liquid. The liquid
reverts to gas when the valve on the cylinder
is opened.
LPG is a flammable gas. It can be a fire and
explosion hazard if stored or used incorrectly.
Store cylinders vertically and securely, to
prevent them from toppling.
Do not mount your LPG cylinder horizontally
or use liquid phase gas cylinders. Liquid–gas
explosion may result. Read the product label
or contact product manufacturer for details.
LPG is heavier than air. Should a gas
leak occur the fitted floor vents allow the
gas to escape from the caravan. For this
reason always ensure that floor vents are
unobstructed.
!WARNING: The boiler compartment
contains the gas connection, floor vents and
the flue hoses. Do not place stowage in the
boiler compartment.
In the event of a gas leak, or if you smell gas:
• Extinguish all naked flames
• Open all doors and windows
• Close all gas valves, including the valve on
the cylinder.
• Do not smoke.
• Do not operate any electrical appliances or
switches.
• Arrange for immediate inspection of the
gas system by a competent person in
accordance with current local regulations.
LPG from the cylinder is reduced in pressure
by a regulator, and is supplied to the boiler
at low pressure (30 mbar). Never use an
unregulated high pressure supply.
Where oil and dirt in the gas supply are a
concern, gas filters should be fitted to prevent
blockage of the boiler gas valve.

FITTED EQUIPMENT
110
Gas heating must not be used whilst driving
your vehicle unless a safety shut-off device
is fitted to the gas system. Current local
regulations must be adhered to.
Flue
The burning of LPG produces CO² (carbon
dioxide), a non-toxic, asphyxiant gas.
Exhaust flue gas can cause possible burns
and poisoning. Avoid inhaling exhaust flue gas.
!WARNING:
Do not position awnings, tents or other
enclosures around the flue terminal.
Air supply is essential for clean combustion.
The air intake is located in the flue terminal. For
best performance, the flue terminal should be
well vented. If leaving the gas heating unused
for a period, ensure the flue terminal is covered
to prevent pest animals nesting in the flue.
!WARNING:
Do not obstruct the flue. Be careful not to
flood the flue when washing the vehicle.
!WARNING: Air is sucked into the
combustion chamber via the air intake.
The gas heating must not be used when
refuelling the vehicle at the service station or
related facility.
Maintenance
There is no manufacturer’s service requirement
for the Alde 3020 Compact boiler itself.
Current local regulations must be adhered
to. The installation of the boiler should be
inspected annually for gas safety.
LPG hoses should be regularly checked for
signs of damage and should be replaced, at
maximum, after 5 years of use.
Bleed air from the system when newly filled,
when the vehicle has been standing unused
for a period, and before departing on holiday.
The fluid level in the expansion tank should be
about 1 cm above the MIN mark when cool.
The heat transfer fluid (HTF) should be topped
up if below this level, to prevent a break in
circulation. Only top up with compatible HTF.
Never leave the system empty of HTF.
!WARNING: Always replace the HTF in
accordance with the antifreeze product’s
lifespan. If in any doubt, replace the HTF
after 2 years.
Failure to maintain the condition of HTF may
result in frost and/or corrosion damage, and is
not covered under warranty.
When the hot water cylinder is in continuous
use, it should be drained and refilled once a
month. This recreates the air cushion in the hot
water cylinder that absorbs pressure surges.
Winter
When camping in the winter, always ensure the
flue terminal remains unobstructed by snow
and ice. Extensions for roof flue terminals, and
condensate spouts for side flue terminals are
available from Alde.
Check the strength of the heat transfer fluid
(HTF) with a hydrometer and/or refractometer.
It should measure 50% ethylene glycol
antifreeze, or -35–37 °C.
The central heating can still be used with no
freshwater in the system. The air in the hot
water cylinder is heated but no damage can
result.
!WARNING: Always drain down and
completely empty the hot water cylinder
when there is risk of frost, unless the vehicle
is explicitly stated to be self-winterising by
the vehicle manufacturer.
If camping in temperatures below -10 °C,
consider carrying spare parts in the event
of an emergency. Alde recommends a 12 V
circulation pump for the expansion tank (with
cabling), a PCB, and 4–5 litres of ready to use
antifreeze. These spare parts should be kept
well insulated and in the warmest part of the
vehicle; for example, in the wardrobe, near to
the expansion tank pipes.
ALDE HEATING OPERATING INSTRUCTIONS

FITTED EQUIPMENT
111
If storing the vehicle for winter, ensure the flue
terminal is covered to prevent pest animals
nesting in the flue.
If using the light duty 12 V circulation pump in
the expansion tank, do not leave the central
heating on over winter, even with a low desired
temperature set.
Note: Air the vehicle over winter without
wearing out the light duty pump. Use
the programmable Alde control panel to
automatically heat the vehicle for 24 hours,
once a week.
