Jøtul Chimney system
Extension casing
The casing comprises four plates and one stay plate.
The plates for the casing are attached with the aid of
a “snap lock” and cannot be separated once they have
been assembled, so make sure that the ends of the
plates are completely even before you assemble them.
Use a wooden mallet or similar, but make sure you
protect the plates so that they do not sustain damage
when you are assembling them.
Once this has been done for all the supplied telescop-
ic sections, the stay plate’s edges are folded down and
the locking lips are bent up.
Assemble the casings with the stay plates.
The casing must then be cut at an angle along the
roof pitch in accordance with the table. As the hood is
rectangular, make sure that you cut along the casing’s
long side.
Then install the casing on the lower fitting. Adjust the
casing so that it is correctly positioned before attach-
ing it with the enclosed screws along the long side.
Pre-drill using a 3 mm drill bit.
If several casings are used, assemble these and secure
them at the joints with screws on all sides. Pre-drill
using a 3 mm drill bit. Minimum 10 cm overlap at the
joints.

Installation of telescopic section and rain protection
The telescopic section is pre-installed with the roof.
The roof has guides regarding where the curved rain
guard should be installed, and there are two direc-
tions to choose between.
Before installing the telescopic section on the casing
kit or on the lower fitting, note which location of
the curved rain guard is most appropriate in relation
to the wind direction. Thread the telescopic section
down over the casing so that the roof bottoms out
against the insulation. The inner pipe should now be
level with the upper edge of the hood (max. 10 mm
above).
Then screw the rain guard onto the telescopic sec-
tion’s pipe hood in the indicated holes.
Finishing by screwing the rain guard’s locks into place
on the opposite side, in the indicated holes. Place
the rain protector piece in the flue pipe (must not be
glued in place).

If the chimney is exposed to a lot
of wind – position the curved rain
guard in the direction of the wind
to ensure optimum protection.
