3 INSTALLATIONINSTRUCTIONS

TheboilermustbeinstalledbypersonnelauthorisedbytheDepartmentofIndustryinaccordancewith

the applicable regulations and standards in force. However, the following recommendations must be

compliedwithwheninstallingthe boiler:

3.1 Location

The boiler must be installed in a enough ventilated room and sufficient access space must be

maintained to carry out preventive or corrective maintenance operations.

3.2 HydraulicInstallation

The hydraulic installation must be made by qualified personnel. The applicable installation

legislation is to be complied with, and the following recommendations should also be taken into

account:

-Theinsideoftheinstallationpipingshouldbethoroughlycleanedbeforeswitchingontheboiler.

-Werecommendinsertingcut-offvalvesbetweentheinstallationpipingandtheboilertosimplify

maintenancetasks.

- If a shut-off valve is fitted at the DHW inlet, it must have a safety valve incorporated, calibrated

to9bar.

- For correct boiler functioning, there must be a pressure of at least 0.5 bar in the domestic hot

watercircuit.

- Before starting up the unit, it is essential to install the condensation siphon supplied with the

boilerdocumentationonthecondensationdraintubeonthebackoftheboiler.

-The condensation pipe should lead to a drain outlet,as

the Evolution boiler is a condensation boiler and a large

amount of water may be generated. This connection

should be made in accordance with the regulations for

draining off condensation water to the drain network.

- Fill the siphon with water before starting up the unit, to

preventfumescomingoutofit.

3.3 ElectricalConnection

The boiler is equipped for connection at 230 V~, 50 Hz to terminals 1and 2of terminal strip J1 (see

“

ElectricalConnection Diagram

”). Remembertoearththeappliance.

The boiler has two terminal strips, TA1(J5) and TA2(J7) for connecting room thermostats or room

chronothermostats(see“

ElectricalConnectionDiagram

”)forremotecontrolofheatingcircuits1and

2 respectively. To correctly connect the room thermostats, firstly remove the bridge joining the

terminalsofterminal stripTA1.Forconnectionto TA2,simplyconnect thethermostattotheterminal

strip.

3.4 FuelInstallation

The Evolution boiler is supplied with a Domestic sealed oil burner

(2)

(see model in “Technical

Characteristics”). For the fuel installation, proceed in accordance with the burner instructions

enclosed with this manual (see “Burner” section). The oil line installation and start-up of the burner

mustbecarriedoutbyqualified,authorised personnel.

3.5

3.6 InstallingtheSRAM2/EVUnderfloorHeating Kit (Optional)

The procedure for suitably connecting the SRAM2/EV Underfloor Heating Kit to the Evolution EV

HAMboilerisasfollows:

-Unplug the boiler from the mains.

- Connect a flow temperature sensor (supplied with the kit) to sensor terminal strip J3 (terminals

15 and 16), first removing the resistance (Rr) supplied by default (see “Electrical Connection

Diagram").

-Fitthetemperaturesensorbulbaccording to theinstructions enclosed with thekit.

- Connect the heating pump to supply terminal strip J2 on the circuit 1 pump connection (pump

BC1;terminals N and 7)(see“Electrical Connection Diagram").

- Connect the PWMCcable to sensor terminal strip J3 (terminals 13 and 14) (see “Electrical

ConnectionDiagram").

-Connectthe3-waymixervalvemotortosupplyterminalstripJ2(terminalsN,8(+)and9(-))(see

“ElectricalConnectionDiagram").

Forcorrecthydraulicinstallation,carefullyfollowtheassemblyandconnectioninstructionsenclosed

withtheSRAM2/EV kit.

3.7 Installing heatingcircuit 2 (Optional)

All the models in the Evolution range of boilers are supplied with a circulation pump connected to

heating circuit 1 (BC1). In addition to this circuit, all the models are designed to control a second

heatingcirculationpumpina second heating circuit (circuit 2, BC2).

The hydraulic installation of heating circuit 2 should be made using the optional flow circuit (IC') on

therearoftheboiler(see"DiagramsandMeasurements").IfthereisanSRAM2/EVunderfloorheating

4 COMBUSTION PRODUCTS EXHAUSTION

The Evolution boilers are balanced flue oil boilers, so that the combustion products exhaustion is

carried out by means of an outlet duct and an air intake from outside. It can also work by taking the

air intake for the burner from the room, this is how the boilers come set from factory. To operate in

this mode, the room must be sufficiently ventilated and not obstruct or block any ventilation

openings.

4.1 External position of the gasevacuationpipesterminal

The installation of exhaustion of the products of combustion has to be carried out by qualified

personnel staff and it will fulfill the requirements demanded in the legislation and effective

regulatory schemes.

(*)Providing the width of the balcony is not over 2000 mm.

(**)If the materials from which the pipe is made are sensitive to the action of the flue gases, this distance should be over 500 mm.

IMPORTANT: All accessories used for combustion product removal and air intake are to be those

supplied by DOMUSA TEKNIK.

4.2 Preparationoftheburnerair intake for balanced flue operation mode

Evolution boilers come prepared from factory for operation by taking the intake air for the burner

fromtheroom.

In case of choosing room sealed mode operation, with the evacuation of the combustion gases

through an outlet conduct and a independent external air intake, air intake for the burner must be

preparedfollowing these instructions:

- Removethetoppanel (1).

- Turn the air intake conduct (2) andtakeouttheairintaketerminal (3) porfromtheback(4).

- Tie air intake terminal (3) atthe back (4) with twoscrews (5) (included in the documentation

bag).

- Removethegrid(6)(this won´t be used).

- Reattachtheroof(1).

4.3 Combustionproductsexhaustion and airintake dual-duct device ø80 (typr C53)

For this type of boiler, the removal of combustion products and air intake take place through

separate Ø80 mm. dual ducts. The Ø80 dual duct outlet kit, code CGAS000186, is used for this

purpose.This is the type of fume removal provided for Evolution boilersby default.

The maximum length of pipe that can be installed is 15 metres for the model EV 35 HAM and 17

meters for the model EV 25 HAM, which is the result from adding the pipe metres for the air intake

and those of the combustion products exhaustion. Each elbow of 90°, or two of 45°, reduces the

availablelengthby1meter andeachhorizontal meter is equivalent to 2vertical meters.

It is recommended that the exhaustion duct be fitted in a slightly upwardly-inclined direction, at

around2º-3º,thuspreventinganywaterandcondensationfromdrippingout.
