Fitted Equipment
circulation pump is operating. In newly filled
systems, small air bubbles can form in the
expansion tank, creating a murmuring sound.
If the circulation pump is stopped for a few
seconds, the bubbles will disappear.
Bleeding
If a bleeder screw is fitted to the outgoing
pipe on the rear of the boiler, open this
bleeder screw and leave it open until it starts
to discharge water. If the boiler is fitted with
an automatic bleeder, there is no need to
bleed it manually.
Start the LPG boiler. The circulation pump
should be switched off. Open the remaining
bleeder screws in the system (please refer to
the instruction manual of the vehicle for their
locations). Leave the bleeder screws open
until they start discharging fluid. Start the
circulation pump and let it run for a while.
Check that the pipes and radiators around
the vehicle are heating up. If they still fail to
heat up, try the following:
Single-axle caravans: Stop the circulation
pump. Using the jockey wheel, lower the
front of the caravan as far as possible so that
the rear is tilted upwards. Leave it in this
position for a few minutes to allow the air to
travel upwards in the system. Open the
bleeder screw at the highest point. Leave it
open until it discharges glycol fluid.
Using the jockey wheel, raise the front of the
caravan as far as possible and repeat the
procedure in this position. Then position the
caravan horizontally and start the circulation
pump. Check that the pipes and radiators
around the vehicle are heating up.
Motor caravan or twin-axle caravan: The
easiest way to bleed the heating system is to
place the vehicle on a sloping surface or to
raise one end of the vehicle using a jack.
Bleed the system as described above.
