ENERGA 80-50
The air, which is piped in through a grill in the wall, ensures that the air in the room is
refreshed and is also used for the combustion process.
The combustion air is sucked in through the grill in the chimney breast and through the
opening underneath, or at the side of the appliance. Because some of this air passes
through the chimney breast, it can be referred to as pre-heated combustion air.
The built-in appliance can also be fi tted with an air duct which draws the combustion air
directly from outside.
The air intake must have a opening of at least Ø125 mm. If required, the air pipe can be
fi tted with a control damper. In this case, the position of the damper must be visible from
the outside. The use of a direct combustion air intake is strongly advised if the appliance
is fi tted with a convection fan set.
The casing / fi replace
• The casing may not be directly connected to the built-in fi re, but must be constructed
so that it is self-supporting; a mantle iron or lintel should be used for this. The
covering in the area must be of non-fl ammable materials of fl ame-retardant material
class A1. This includes bricks, cladding, ceramic tiles, metal or plasterwork, Promatec
and Nobranda.
• The opening for incoming and outgoing air from the casing must be at least totally
900 cm². At least 200 cm² from the opening for incoming and outgoing air must not be
closable.
• The ventilation of the casing/fi replace can be provided by grills, but this can also be
achieved by not building the fi replace right up to the ceiling (leaving a gap of 5 cm).
