Installing the flue duct
RISK OF INJURY
The insides of the flue ducts may have sharp edges.
We recommend wearing protective gloves during
installation.
1 Separate the flue ducts. To do this, remove the
adhesive tape.
2 Remove the protective film from both flue ducts.
3 Insert one flue duct into the other.
Note: Avoid scratching the flue ducts when
inserting them, e.g. by placing the installation
template as protection over the edge of the outer
flue duct.
•
Note the position of the slots in the flue duct!
– Exhaust-air mode: Slots of the inner flue duct
downwards.
– Circulating-air mode: Slots of the inner flue
duct upwards.
