4.3 Installing the ventilation system
Fig. 21
The upper ventilation grille should be posi-
tioned as high as possible above the con-
denser (Fig. 19) .
Install the lower ventilation grille at floor
level of the vehicle (Fig. 20), allowing unburnt
gas (heavier than air) to escape directly into
the open air. The gas burner must be loca-
ted above the edge (1) .
Should this arrangement prove impossible,
a ventilation aperture must be introduced
by the manufacturer of the vehicle into the
recess floor in order to avoid the accumula-
tion of unburnt gas on the floor (Fig. 21).

Ventilation aperture
The ventilation grilles must have an open
cross-section of at least 400cm². This is
achieved by using the Dometic LS 300 absor-
ber ventilation and air extraction system
which has been tested and approved for this
purpose.

An installation other than described will
reduce the cooling capacity and jeopardi-
se the manufacturer's warranty/product
liability.
CAUTION!
Correct mounting of the lower ventilation gril-
le facilitates access to the connections and
functional parts during maintenance.
