Facade sleeve through a facade of
non-flammable material
Read the "Installation Conditions" chapter care-
fully and follow the installation instructions
below.
The following illustration shows the situation of a fin-
ished facade sleeve.
1. Start at the stove and add the concentric pipes
one component at a time along the route you
decided on in advance.
2. Next, install a concentric elbow and possible hori-
zontal change in direction and decide on the loc-
ation of the sleeve.
3. Make a 10 mm larger hole in the facade in such a
way that the air intake duct drains to the outside.
Use a 1 - 3 degree angle or a slope percentage of 2
-5% for this.
Prevent dust and/or grit from getting into the
stove when drilling.

4. Decide on the length of the facade sleeve and
shorten the intake to the wall if necessary. Allow
the flue gas duct to extend approximately 10 mm
from the air intake duct.
5. Remove burrs and sawdust.
6. Extend the facade sleeve through the facade from
the outside, with the "TOP" up, connect to the con-
centric elbow and attach it to the outside of the
facade (make sure the air intake cover drains to
the outside).
7. If so desired, the hole on the inside of the wall can
be finished with a wall plate.

flammable material
Read the "Installation Conditions" chapter care-
fully and follow the installation instructions
below.
1. Follow instruction steps 1 and 2 in the preceding

the following two ways; see the illustration below.
a. Use a protective duct (1) of non-flammable
b. Make a tube (2) of non-flammable material,
