the system. The central heating pump is activated depending on the temperature set on the control
panel. Turning on the Hot water boost function will turn off your central heating pump.
3.1.6
System Temperature
The boiler is set to a system temperature of 80
°
C, i.e. the temperature of the glycol fluid as it circulates
in the heating system.
3.1.7
Air Circulation
In order to achieve the best possible result from the principle of connected heat, it is important to allow
air to circulate freely under bunks, and behind backrests and wall-mounted cabinets. Ensure that the
carpet does not obstruct the air supply to the radiators. It is just as important that cushions or blankets
do not interrupt the flow of air behind backrests and wall cabinets.
3.1.8
Maintaining the Heating system
Winter camping
In winter, ensure that the flue is kept clear of snow and ice,
since the inlet air to the LPG boiler enters through the flue. Do
not start the LPG boiler until the flue is completely free of snow.
A flue extension (part no. 3000 320) for fitting on the roof is
recommended for winter camping.
The LPG system
The LPG system should be checked regularly by a professional, who will
ensure that there are no leaks from connections or hoses. LPG hoses should
be changed according to national regulations, maximum of five years. Check
the date stamp on the hose. Hose has a propensity to dry out and crack. To
increase safety, we recommend fitting an Alde leak gauge, type 4071, as
close as possible to the pressure reduction valve.
The heating system
Regularly check the heating system’s fluid level in the expansion tank. The level should be about 1cm
above the minimum indicator in a cold tank. The heating system should be filled with a mixture of water
and glycol. For preference, use high quality readymixed glycol (with inhibitor) intended for use in
aluminium heating systems. If using concentrated glycol, the mixture should consist of 60% water and
40% glycol. If the heating system will be exposed to temperatures below -25
°
C, the glycol content must
be increased, but not to more than 50%. Any vessels used for the liquid must be spotlessly clean, and
the pipes in the heating system must be free of contamination. This will prevent the growth of bacteria
in the system. The glycol mixture should be changed every second year, since its ability to protect
against corrosion, for example, will deteriorate. The glycol content should be checked before topping
up with new liquid. This will ensure that the concentration of glycol in the mixture is not too high. If the
fluid level in the expansion tank falls for reasons other than evaporation, please check all joints, drain
cocks and bleeder screws to ensure that they are not leaking. If the glycol-water mixture leaks out,
rinse with water and wipe up. Never allow the heating system to stand empty of glycol.
