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

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.

height and the boiler should be hor-

izontal. Ensure that the wheels are

not in contact with the oor!

Water and gas connecons should

be done aer adjusng the feet, as

they aect the exact height of all

connecons.

Installaon

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.

Installaon

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.

Installaon

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.
