In this case, for gas operation, do not use the upper winter cover!
If even with draught-free installation a fume chimney is desirable, you must incorporte
the L100 ventilation and extraction system
into the upper air vent opening.
Installation of fume chimney: please refer to point 6.7.
Ventilation and extraction
A correct installation is important for correct operation of the appliance to ensure, there
is no a build-up of heat at the back of the appliance; this heat must be allowed to escape
into the open air.
In the event of high ambient temperatures, full performance of the cooling unit
can only be achieved by means of adequate ventilation and extraction.
Ventilation is provided for the unit by means of two apertures in the caravan wall.
Fresh air enters at the bottom, extracts the heat and exits through the upper vent
grille.
The upper ventilation grille should be positioned as high as possible above
condenser (A).
The lower ventilation grille should be flush with the floor of the vehicle, allowing
any gas leakages (heavier than air) to escape directly into the open air.
If such an arrangement is not possible a hole must be provided under the refrigerator
(not close to the burner) so that any leaking LP gas can escape. This must have an
effictive area of at least 13cm². It is desirable to fit the hole with wire mesh or similar,
and an angle plate to protect it from stones, mud etc., the wire mesh must not reduce
the effective area of 13cm² ( EN 1949).
The ventilation grilles must have an open cross-section of at least 250 cm2.
This is reached using the Dometic Absorber Ventilation and Air Extraction
System L100 / L 200 that has been tested and approved for this purpose.
Comment:
If the distance between the wall and the refrigerator is greater than 20 mm the gap
can be reduced to 20 mm by fitting a suitable baffle piece.
