•
Set the temperature to 30°C and select
gas heating on the control panel.
•
Set the 12v inline circulation pump on the
side of the boiler to speed 5 (Fig.1 [D]):
see page 62, by turning the blue speed
dial clockwise, on the face of the pump
motor. NB: Speed is not adjustable if using
the 12v 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
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 anti-clockwise between thumb and
forefinger. Air will hiss out. When fluid
trickles out, close the bleed screw and
mop up fluid with the cloth.

•
Move on to the next bleed point and
repeat, until all bleed points have been
attended to.

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.

LECTRIC
The Alde 3020 Compact boiler has two 230v
electric heating elements outputting 1050W
and 2100W or 3150W combined. Drawing 5A, 9,
and 14A respectively (rounded).
230v breakers, fuses, fused spurs and isolator
switches should be rated for 16A.
Before using electric heating, check the
current limit on the electric supply you are
hooking up to.
6A limit, only use 1kW electric heating.
10A limit, use 1–2kW electric heating.
16A limit, use 1–3kW electric heating.
NB: If the electric supply has unstable voltage
the amperage will also fluctuate.
Alde recommends fitting the 3010-
246 load monitor allowing you to set
a limit on the current drawn by the
vehicle and the electric heating to
automatically accommodate it.
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 a 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°C to
30°C. For temperatures less than 13°C, the use
of propane should be considered’.
