Operating modes and systems
●
Rüegg fireplace inserts are designed so that the
combustion air
can be
drawn to the fireplace separately from the ambient air, for closed-door opera-
tion. The combustion air is taken from outside the room in which the fireplace
is installed and is channelled directly to the fireplace where it is drawn into the
fire. The system is called
AIR-Direct
(= separate from ambient air)
● The second system for drawing air into the fireplace is the
convection air
system, which is used mainly for heating the ambient air. Fireplaces in which
the convection air is guided by a convection jacket are called S fireplaces,
while those without the jacket are called K fireplaces. In this system, the con-
vection air is taken in through a cavity in the fireplace casing and comes out
into the room through vents in the fireplace apron.
● If the fireplace insert also needs to operate with the door open, the convection
air system must be connected to an external air source. This means that the
external air will be heated by the convection air system and drawn into the
room and will arrive in the fireplace as combustion air, going through the open
door.
WARNING
If an open fired appliance is only supplied with fresh air by the AIR
DIRECT system, and the room is characterized by an airtight con-
struction, a trouble free function cannot be guaranteed!
WARNING
Internal or external fans may never be attached to the combustion
air supply (AIR DRECT system) they are only used for advanced
convection air supply.
