Dimensions of the boiler are given in
Figure 6.
When connecting the flue, the flue gas accessories
supplied by the manufactured must be used. When
selecting the location of the boiler the position of
flue gas connection and flue terminal should be
considered. For flue connection the requirements
set forth by the local authorities and gas distributing
company must be observed.
Flue connection must not be made to:
a.
Building stairwells,
b.
Building aisles,
c.
Light-wells,
d.
On the chimney walls
e.
Balconies
f.
Elevator shafts.
The followings must be observed when making flue
connection:
a.
Flue terminal vertical distance to eaves and roof
coverings should be minimum 1,5 m from the top
and should also extend further from such eaves
and roof coverings.
b.
Minimum vertical distance above the ground
should be 0,3 m and in places where there is an
impact risk the flue terminal must be covered
with a wire net.
c.
When the flue terminal is extended off the wall it
must extend minimum 50 mm outside the wall.
d.
Horizontally connected flue connections must be
installed with 1% downward slope.
e.
Where the appliance is installed to penthouses
flue terminal should be minimum 40 cm above
the roof. In such cases the roof must be insulated
with non-combustible material.
f.
Maximum length of the flue connection is 4 m.
Maximum length is shortened by 1 meter for
each additional 90° elbow and 0,5 meter for each
additional 45° elbow.
g.
Roof tightness must be fully ensured with vertical
flue applications. In case where tightness cannot
be ensured any failure or damage which may
arise is out of warranty claim.
