The rain collar is suited for roofs with an incline of
0-30° covered with felt or tin and many plate or
tile roofs, if their profile does not prevent a good
attachment of aluminium and glue.
On a metal-sheeted roof we recommend using a
ridge flashing sheet (Roof ridge cylinder flashing
extension sheet 1250 mm x 800 mm, stain- less
steel). The sheet must reach from the ridge to the
top of the back edge of the rain collar, using
the necessary amount of extension sheets. The
ridge flashing must extend at least 50 mm onto the
top of the rain collar’s back edge.
If the roof piercing goes through the seam of a
machine-seamed roof, the ridge flashing needs to
be made by a qualified roofing firm.
The rain collar is glued to the roof (using, for in-
stance, Wurth or Sikaflex glue/sealing compound or
an equivalent product). The roof must be complete-
ly dry before you glue the chimney root’s sealing
into place. It is not enough that the surface feels dry.
It must be internally dry, as well. The glue manufac-
turer’s instructions regarding temperatures must
also be accounted for.
Installation steps:
1. A suitable hole for the chimney is opened into
the rubber collar as follows:
• Cut a knife mark into the front of the ripping
tab at the correct spot for the chimney’s external
diameter
• Pull by the ripping tab to remove a piece that
leaves a smaller hole than needed.
• Stretch the rain collar carefully over the
chimney mantle.
2. Check that the rain collar settles evenly on the
roof according to its incline. On a tile roof, the
collar is pressed against the roof to make it bend
into the correct shape and installed by at least
50 mm underneath the upper tile and by the
same amount on top of the lower tile.
3. Make sure it does not overlap the lower tile’s
border and cut it to size, if necessary.
4. Glue the parts of the rain collar that contact the
roof into place with glue/sealing compound.
5. The rubber’s upper end is sealed against the
chimney with a clip (included in the package).

USING THE CHIMNEY AND
MAINTENANCE
3.1. CHIMNEY SWEEPING
Make sure that the chimney is swept regularly and
check it visually at least once a year. The lifespan of
the chimney is most affected by the material burned
in the furnace and the way it is burned.
3.2. CHIMNEY MAINTENANCE
Good chimney maintenance includes regular check-
ups at sufficiently frequent intervals, i.e. monthly,
and, if needed, with the help of the chimney sweep-
er. If the chimney has been unused for a long period,
make sure before you use it that it is in good condi-
tion and not blocked (for instance by a bird nest).
The Helo-chimney should be swept with a stainless
and acid-proof or nylon brush.
