11 Roof sleeve
The conversion set consists of parts 3, 4, 5, 7 and 9.
Follow the instructions below for assembly and see the
figure above.
1. Lead the flexible hose (6) through the existing pipe
(8).
2. Attach the slide (4) to the lower end of the flexible
hose and secure it with two Parker screws (5).
3. Keep the bottom of the slide even with the bottom of
the pipe or the ceiling. Cut the flexible hose at approx-
imately 100 mm above the chimney cap.
4. Attach the installation plate-outside (9) to the flexible
hose, clamp it with a hose clamp (7) and secure it all
with a Parker screw (5).
5. Attach the installation plate-outside (9) watertight to
the chimney cap with silicon sealant and stainless
steel screws.
6. Install the roof sleeve (11) and secure it with the
clamping strap included in the delivery (10).
After the roof sleeve is installed, the slide (4)
should extend about 100 mm under the pipe or ceil-
ing.
7. Attach the installation plate-inside (3) gastight on the
bottom of the flue or on the bottom of the ceiling with
silicon sealant and stainless steel screws.
8. Place the stove (1) as indicated in the chapter "Install-
ation requirements".
9. Connect the stove with the lower end of the flue using
concentric components (2). All components must
overlap at least 30 mm and be secured with clamping
straps or stainless steel Parker screws to prevent
them from coming apart. Extend the concentric pipe
at least 100 mm into the existing flue.
The slide (4) should therefore extend about 200
mm into the inner duct of the top concentric com-
ponent. If this is not the case, the flexible hose (6)
will be kinked in the chimney, preventing the sys-
tem from functioning properly.
11. Finally, install the clamp strap in the installation plate-
inside (3).

Roof sleeve through a flat roof of
flammable material
Read the "Installation Conditions" chapter carefully
and follow the installation instructions below.
1. Start at the stove and add the concentric pipes one at
a time, including the changes in direction you want,
along the route you decided on in advance, up to just
under the roof.
2. Decide on the location for the roof sleeve.
3. Make a hole with a 250 mm diameter, so that a fire
separation of 50 mm remains round the pipe.
4. Attach a square installation plate (of at least 300 mm
and with a sufficiently large centered round hole) (1)
or 2 centering plates with screws to the bottom of the
roof partition to center the pipe; see following figure.
5. Insert a clamping strap (2) in the installation plate by
first turning it in and then out.
6. Extend the concentric pipe (3) until it extends at least
400 mm above the roof surface (more is permitted up
to a maximum of 1000 mm stand-alone).
7. Slide the roof sheet (4) over the pipe and tighten it
with screws.
8. Finish the seam between the pipe and the cone of the
roof sheet or lead slab watertight with silicon sealant
and if necessary a storm collar (5).
9. Install the roof sleeve (6) and secure it with the clamp-
ing strap included in the delivery.
10. Make sure the roof sheet is covered watertight. Use
lead, tar and/or silicon sealant for this, depending on
the existing roofing.
