Air Supply; Cupboard Or Compartment Ventilation; Electrical Supply - Vaillant TURBOmax Pro 28 Instructions For Installation And Servicing

Air supply

Detailed recommendations for air
supply are given in BS 5440: Part 2.
It is not necessary to have an air vent
in the room or internal space in which
the boiler is installed.
Cupboard or compartment
ventilation
TURBOmax Pro combination boilers
are very high efficiency appliances.
As a consequence the heat loss from
the appliance casing during
operation is very low. For cupboard
or compartment installations it is
therefore not necessary to provide
any high or low level permanent air
vents for cooling purposes.
