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.
