Operang principle
The SUPAo EVO is a fully modulat-
ing boiler.
The control unit of the boiler adapts
the modulaon rao automacally
to the heat demand requested by
the system. This is done by control-
ling the speed of the fan. As a result,
the mixing system will adapt the gas
rao to the chosen fan speed, in
order to maintain the best possible
combuson gures and therewith
the best eciency.
The ue gases created by the com-
buson are transported downwards
through the heat exchanger and
leave the boiler at the boom into
the chimney connecon.
The return water from the system
enters the boiler in the lower sec-
on, where is the lowest ue gas
temperature in the boiler.
The water is being transported up-
wards through the heat exchanger,
in order to leave the boiler at the
ow connecon. The cross ow
working principle (water up, ue gas
down) ensures the most ecient
combuson results.
The LMS14 control unit can control
the boiler operaon based on:
• Boiler control
(stand alone operaon);
• weather compensated operaon
(with oponal outdoor sensor);
• with 0-10V external inuence
(temperature or capacity) from a
building management system.

Boiler transport
The SUPAo EVO boiler will be
supplied as a complete unit being
fully assembled and pre-tested.
The maximum width is 466 mm for
models SF61-SF63 EVO and 746 mm
for models SF64-SF67 EVO, which
makes it possible to transport all
models through a normal door in
one piece. The boiler can be trans-
ported by using the wheels or with a
pallet truck, entering only from the
side.
Whenever necessary, the boiler can
be dismantled into smaller parts for
easier transport inside the building.
The table below shows the main dis-
mantled parts with their weight and
dimensions.
When the boiler has to be trans-
ported with a crane, it is necessary
to remove the casing before con-
necng the boiler to the crane. Al-
ways connect the crane to the frame
of the boiler by using straps.

Warnings before installaon
Boiler installaon
Boiler installaon
The boiler should be posioned in a
frost-proof boiler room. If the boiler
room is on the roof, the boiler itself
may never be the highest point of
the installaon.
When posioning the boiler, please
note the recommended minimum
clearance in the picture. When the
boiler is posioned with less free
space, maintenance acvies will be
more dicult.
To opmize the posion of the boiler
in the room it is possible to exchange
the posion of the electrodes from
the right side of the boiler to the le
side of the boiler.
This also means that the required
space as indicated in the picture will
be mirrored.
Normal: Le 250mm / Right 450mm
Modied: Le 450mm / Right 250mm
Once the boiler is in the correct
posion, the adjustable feet (2)
(with vibraon absorpon damp-
ers) should be adjusted to the right
Installaon, rst ignion, maintenance and boiler repair, must be performed by qualied
persons, according to the naonal installaon provisions and any requirements of the local
authories and public health agencies.
Before installing the appliance
Before connecng the boiler, it is
rst necessary to perform the fol-
lowing operaons:
• Carefully wash the system pip-
ing in order to remove any screw
thread or welding residues, or
any dirt which might prevent the
boiler from operang correctly;
• Make sure that the boiler is set
up for operaon with the type of
gas available (read the informa-
on on the packaging label and
on the boiler data plate);
• Make sure that there are no ob-
stacles inside ue exhaust and
that it does not contain any dis-
charge from other appliances,
unless the ue is meant to serve
more than one boiler (in accord-
ance with current legal require-
ments);
• Where there is already a con-
necon to exisng ue exhausts,
check that these exhausts have
been perfectly cleaned and are
without residues, because any
disconnecon could obstruct the
passage of fumes and create po-
tenally dangerous situaons;
• In areas with parcularly hard
water, limescale may build up on
the components inside the boiler
and reduce its overall eciency;
• In case of installaon near wall
sensive to heat (for example
wood) make sure to protected it
by suitable insulaon;
WARNING!
No ammable items should be le
near the boiler. Make sure the in-
stallaon site and any systems to
which the appliance must be con-
nected are fully compliant with
the current applicable legislaon.
Install the boiler respecng the
minimum distances from any am-
mable materials. If dust and/or ag-
gressive vapours are present in the
room in which it is to be installed,
the appliance must operate in-
dependently of the air inside the
room.

Connecng the boiler
Connecng the boiler
This chapter will explain how to
make all connecons to the boiler
with regard to:
• Hydraulic connecons
• Condensate drain connecon
• Gas connecon
• Flue gas connecon
• Air intake connecon
(under casing)
• Electrical connecon
The boiler should always be con-
nected in such a way, that the sys-
tem applies to all relevant standards
and regulaons (European, naonal
and local). It’s the responsibility of
the installer to ensure that all stand-
ards and regulaons are respected.
Hydraulic connecons
The boiler should always be con-
nected in such a way, that water
ow through the boiler can be en-
sured at all mes.
Connect the ow (4) and return
(5) of the boiler tension free to the
system.The (oponal) 2nd return
kit allows the boiler to be used in a
system with two return circuits. The
common return becomes the low
temperature return, the 2nd return
connecon (6) is the high tempera-
ture return.
The (oponal) accessory kit with
safety valve, manometer and deaer-
ator should be mounted on the ow
connecon (4) of the boiler, before
connecng to the system.
The (oponal) pump kit should be
mounted directly to the return con-
necon (5) of the boiler, before con-
necng to the system.
Condensate connecon
The syphon (included in delivery)
should be installed to the connec-
on at the boom of the condens
tray (7).
Lead the pipe through the hole at
the back (8) of the boiler and con-
nect it to the draining system in the
boiler room. The connecon to the
draining system should always be
done with an open connecon, in
order to avoid a ooding of the boil-
er in case of a blocked drain.
Gas connecon
The gas connecon must be made
by an authorized installer in accord-
ance with the applicable naonal
and local standards and regulaons.
Connect the gas line from the sys-
tem tension free to the gas connec-
on (1) of the boiler. A gas isolang
valve should be mounted directly
behind the boiler.
A gas lter can be mounted directly
on the gas connecon of the boiler.

Requirements and regulaons
Regulaons for the construcon of
ue gas systems are very dierent
for each country. It should be en-
sured that all naonal regulaons
with regard to ue gas systems are
respected.
Pay aenon to the following rec-
ommendaons when dimensioning
a ue gas system.
Only approved ue gas material may
be used.
The ue gas system must be prop-
erly calculated to ensure a safe func-
oning of the system.
Flue gas system components should
be removable for maintenance pur-
poses.
You have to take in consideraon the
following material requirements.
Materials
Exclusively materials which are heat
resistant and resistant to ue gases
and aggressive condensate, and CE
approved may be used.

Air intake connecon
The air intake can be connected in
case of room sealed installaon.
The cover (3) must be disassembled
in order to connect the air intake
piping to the connector inside the
boiler.
The diameter should be calculated
according to the naonal regula-
ons, together with the ue gas
system. The total resistance of both
systems should never overcome the
maximum permissible resistance of
the fan inside the boiler (see also
chapter: Technical data).
Flue gas connecon
Connect the ue gas system to the
ue gas connecon (4) of the boiler,
use ue gas systems with seamless
connecons only. It’s not neces-
sary to make a separate condensate
drain for the ue gas system, as the
condensate will be drained via the
syphon of the boiler. Please note the
following issues:
• The diameter of the ue gas sys-
tem must be chosen by calcula-
on according to the naonal
regulaons.
• Construct the ue gas system as
short as possible (for maximum
length see page20).
• Construct horizonal ways with a
minimum angle of 3°.
Connecng the ue
The ue gas system must not be in
contact with or placed near am-
mable materials, and must not cross
building structures or walls made us-
ing ammable material.
This boiler has an integrated high
limit thermostat funcon for the
ue gases. When the ue gas tem-
perature exceeds 90 °C, the burner is
switched o. With this funcon, an
addional (external) safety device is
not necessary.
When replacing an old boiler, the
venlaon and ue gas exhaust sys-
tem must always be replaced.
The ue gas system should be cre-
ated using a male/female coupling
and a seal. Couplings should always
be arranged so that they go against
the direcon of the condensate ow.

Dimensioning single
Dimensioning
When dimensioning a ue gas sys-
tem, it’s necessary to perform a cal-
culaon check of the ue gas sys-
tem in order to verify if the choosen
system is applicable.
The following table shows two ex-
amples of possible ue gas systems,
including the maximum possible
length of the system.
These examples only give an indica-
on of the possible length, but they
can not be used for ocial ue gas
layout calculaon. Each ue gas sys-
tem must be calculated by an au-
thorized company.
The maximum negave ue gas
pressure, which doesn’t aect the
burner modulaon rao, is 30 Pa.
Higher negave pressure will lead to
limitaon of the burner modulaon
rao.
The maximum horizontal ue gas
way is 20 m. With horizontal ways
longer than 20 m, a faultless burner
start in cold condion can not be
guaranteed.
