Boiler room
The boiler room must be built in accordance with applic-
able building regulations.
The floor must not be flammable or must otherwise be
covered by a 0.7 mm thick steel sheet that extends at least
0.5 m out from the boiler in each direction.
Provision for good air supply. The boiler room’s air intake
must have an area of at least 200 cm².
NOTE
Ensure that sweeping can be carried out in accord-
ance with the applicable regulations. If in doubt,
contact a chimney sweep.
Chimney
It is important that the flue is of sufficient diameter and
height that over pressure does not occur in the boiler and
flue.
The flue pipe must be dimensioned in accordance with
building regulations and EN 13384-1 to facilitate a cor-
rectly functioning combustion system. The chimney
draught is of great importance and should be 15 - 25 Pa.
For the best combustion and the lowest environmental
impact a draught limiter should be used. The boiler is
supplied with a draught limiter and an angled flue pipe
for rear connection. Straight flue pipe for connection up-
wards available as accessory.
The flue needs to be inspected and approved before install-
ation.
Pellets
Good quality pellets ensure good combustion and it is
therefore recommended to use pellets that meet
EN Plus
A1
specification.
The boiler must be cleaned and swept more frequently if
a poorer quality fuel is used.
Pellets must be stored in a dry and clean area.
Connection
Pipes are to be installed in accordance with the applicable
heating and hot water standards. Internal support bushes
should be fitted when annealed steel or copper pipe is
used.
The supplied drain valve is installed in the connection on
the boiler’s right or left sides.
The overflow pipe from the safety valves must be routed
to a floor drain to prevent hot water splashes when
checking the valves or when bleeding the boiler. The outlet
of the overflow pipe should be visible. The overflow pipe
must be laid frost free and sloping along its entire length.
The hot water circuit must be equipped with a mixer valve
to prevent scalding.
Current regulations require the heating installation to be
inspected before it is commissioned. The inspection must
be carried out by a suitably qualified person. The installa-
tion inspection must be documented. The above applies
to installations with a closed expansion vessel. If the boiler
or the expansion vessel is replaced, the installation must
be inspected again.
If the heating system is equipped with an open expansion
vessel, the distance between the highest radiator and the
expansion vessel may not be less than 2.5 m.
Min 2,5 m
NOTE
The pipe system must be flushed before the boiler is
connected so that any residual contaminants will not
damage the components.
