Shortening or extension of pipe as needed
• If the connection pipe needs to be shortened by
sawing, the cut must always be at a 90° angle to
the pipe’s length
• The connection pipe can also be extended with
an extension pipe. The extension pipe comes
with a jointing sleeve for easy attachment
• The isolated part can be extended using the Helo-
chimney`s extension parts (500 and 1000mm)

• All segments are installed with the female end up
and attached with tie rings
• Permitted maximum height for the insulated sec-
tion is 5000 mm.
2.3.1. INSTRUCTIONS FROM THE E3
BUILDING CODE
The most suitable location for a chimney is close
to the roof saddle. At the roof saddle, the minimum
distance between the end of the chimney and the
roof covering is 0.8 m measured at the foot of
the chimney. At normal pitches of the roof, 0.1 m
is added for each pane metre measured from the
saddle to the height of a chimney on the slanted
part of the roof. If the water insulation is a roof
covering not belonging to class Broof (t2), the

distance to the covering is at least 1.5 m. When
planning the height of the chimney, combustible
structures and openings and also cambers in the
roof structures at the maximum distance of 8 me-
tres are taken into account.

code regarding chimney height in relation with the
roof’s highest point.
2.4. THE CONNECTION PIPE AND ITS
SAFETY DISTANCE
The non-insulated connection pipe that comes as
standard with the chimney is used when the pipe
does not start out insulated from the top of the de-
vice. The diameter of the connection pipe is 115 or 130
The connection pipe fits Helo fireplaces directly
using their own connecting pipe. The connection
pipes can be shortened by sawing and lengthened
using extension pipes (see next chapter). When
using non-insulated connection pipe, its minimum
safety distance of 400 mm must be accounted for.
When the pipe needs to be shortened by sawing,
it is essential that the cut is perpendicular to the
length of the pipe. When the damper part
is used, it must be located between the
non-insulated pipe and the insulated segment.
