ADDITIONAL
VENTILATION
There must be sufficient free air for combustion into the room where the appliance is installed.
Permanent openings or vents must not be covered. Vents needs to be positioned carefully, they must be
protected from direct wind conditions. A baffle that has been specially designed to fit over the vent will
protect it from the effects of wind, but must not restrict the total vent area and must be secured in a way
that prevents its movement. Regular inspection of any vents is critical to ensure that the vent has not
become restricted. The appliance may require up to 20 m
3
/hour of combustion air. The natural recirculation
of air must be guaranteed by having permanent ventilation to the outside.
