In this case, for gas operation, do not use the upper winter covering!
If even with draught-free installation a fume chimney is desirable, you must incorpor-
te the L100 ventilation and extraction system into the upper air vent opening.
Installation of fume chimney: please refer to point “

Ventilation and extraction
A correct installation is important for correct operation of the appliance to ensure,
there is no 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.
Should this arrangement prove impossible, a ventilation aperture must be introduced
by the manufacturer of the vehicle into the recess floor intended for the unit's installa-
tion, in order to avoid the accumulation, on this floor, of any non-combusted gas which
might escape.
The ventilation grilles must have an open cross-section of at least 250cm².
This is reached using the Dometic Absorber Ventilation and Air Extraction
System LS 100 / LS 200 that has been tested and approved for this purpose.
Comment:
If the distance between the wall and the refrigerator is greater than 20mm the gap
can be reduced to 20mm by fitting a suitable baffle piece.

Deviations shall require the consent of the manu-
facturer.
Correct mounting of the lower ventilation grille facilitates the access
to the electrical and gas connections during maintenance work.
