4. Initial operation of the heating system
CAUTION
Never use the system while under the influence of alcohol, drugs or medicines, and always carefully
follow the safety instructions.
4.1. Pre-operation check of the heating system
• Check that the glycol mixture is at the right level in the system's expansion vessel; see Fig. 2.
The level should be about one centimetre above the MIN mark in cold systems. Ensure that the
system is properly ventilated before putting it into use.
• Check that the chimney is kept free of ice and snow, as induction air enters the boiler via the flue
when run on LPG. Also check that no other objects block or interfere with exhaust gases and supply
air at the chimney.
• Check air circulation. To get the full effect of the waterborne heating, it is important that the air can
pass freely under bed boxes and behind back cushions and wall cabinets. If the vehicle has fitted
carpets, check that they do not prevent air supply to the convectors. It is also important that curtains,
cushions and blankets do not prevent air circulation behind seatback cushions.
