VENTILATION
General
Fixed ventilation is a statutory requirement in
all motorhomes. These ventilation apertures
are positioned at both high and low level and
for your safety should not be obstructed,
even partially.
Low Level Ventilation
Under each appliance is a fixed ventilation
aperture, of a size commensurate with the
rating of the appliance itself. It is either gauze
covered or incorporates a fixed plastic vent.
This should be checked regularly to see that
it has not become blocked.
High Level Ventilation
High level ventilation is provided by the roof
vents. The ventilation provided has been
carefully calculated and relates to the rating
of the appliances in the vehicle. Roof vents
must not be covered with anything that may
limit or affect the ventilation they provide.
Maintenance
Under no circumstances should any fixed
ventilation aperture be blocked, covered,
either partially or fully, or be modified in any
manner whatsoever. They should be checked
at least annually for damage or blockage.
Screens and/or grilles should be kept clean
and free from dust. See diagram of upper/
lower ventilation.
All ventilation complies with BS EN 721 and
vents should not be obstructed in any
manner as this could lead to insufficient fresh
air. In this case the confined atmosphere
becomes depleted of oxygen which leads to
the formation of the highly poisonous gas
‘carbon monoxide’. Carbon Monoxide is
odourless, colourless and tasteless and will
rapidly cause unconsciousness and death
with little or no warning prior to collapse.
THERE IS NO DANGER WHEN ADEQUATE
VENTILATION IS PROVIDED.
When you are cooking, it is essential to
provide additional ventilation such as opening
windows near grill, cooker or oven.
Roof-mounted Flue installations
All flue installations should be inspected once
a year throughout their length for corrosion.
Flues should be replaced if any sign of
perforation is found. Ensure that the
replacement is of an approved type.
WARNING: Never allow modification of
LPG systems and appliances except by
qualified persons.
