4.- INSTALLATION INSTRUCTIONS

The boiler must be installed by personnel authorised by the Department of Industry in accordance with the applicable regulations and standards in force. However, the following recommendations must be complied with when installing t he boiler:

4.1.- Location

The boiler must be installed in a sufficiently ventilated site. It is essential that the boiler is accessible from the side for maintenance purposes.

4.2.- Installation and electrical connection of the boiler.

The pictures below show the two burner assembly operations:

4.3.- Hydraulic Installation

Fit the flexible pipe.

Tighten the bracket.

Connect the electrical

connector.

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:

- The inside of the installation pi pi ng should be thoroughly cleaned before switching on the

boiler.

- We recommend inserting cut-off valves between the installation piping and the boiler to simplify maintenance tasks.

- Before starting up the unit, it is essential to i nstall the condensation siphon supplied with the boiler documentation, in the condensation drain tube on the back of the boiler.

- When the pressure of the domestic water supply exceeds 7 bars, a pressure reducer must be fitted.

page -7

- The condensation pipe must lead to a drain outlet, as the TRO Evolution BH is a condensing boiler and a large amount of water may be generated. This connection must be made in compliance with th e regulations for draini ng off condensation water t o the drainage system.

- Fill the siphon with water before starting up the unit, to prevent fumes coming out of it.

4.4.- Electrical Connection

The boiler is equipped for connection to 230 V in pins 1 and 2. Remember to earth the appliance.

The boiler has two terminals prepared for connecting the room thermostat (see wiring diagram). The bridge that joins the terminals must therefore be removed and the room thermostat connected there.

4.5.- Fuel installation

The TRO Evolution BH boiler is supplied with a Domestic oil burner (see model in "Technical Characteristics"). For the fuel installation, proceed in accordance wi th the burner instruct ions enclosed with this manual (see "Burner" section). The oil line installation and start-up of the burner must be carried out by qualified, authorised personnel.

4.6.- Draining the boiler

The boiler is emptied by opening the drain tap located in the rear of the boiler. A flexible hose must be attached to this tap to direct it to a water outlet. After draining the boiler, the valve must be closed and the flexible tube removed.

4.7.- Precautions for preventing noise during operation

Ensure the flow and return pipes are not touching each other, or insulate them to prevent any vibration noise. The boiler must be correct ly seated on its base and lev elled. Before startup, make sure that the boiler and the system have been properly bled.

4.8.- Filling and bleeding the installation

To fill the installation, open th e fill valve unti l the manometer shows a pressure of 1 - 1.5 bars. The circuit should be filled slowly and with the automatic air bleed valve cap loose, to let the air out of the installation. The air should also be bled from the rest of the i nstallation using the air bleed valves provided. Close the fill valve after filling.

NOTE: Switching on the boiler with no water inside could result in serious damage.

5.- COMBUSTION PRODUCT REMOVAL

5.1.- Combustion product removal

The combustion product exhaust ducts must be installed by qualified personnel and must comply with current legislation and standards.

The TRO Evolution BH boilers are sealed oil-fired boilers, and the combustion products are therefore removed through an outlet pipe, with a separate air intake from outside. We recommend that the position of the outside exhaust duct is as shown in the figures and in the table below:

Removal pipe position

A under a cornice 300 B between two horizontal ducts 1000 C from an adjacent window 400 D between two vertical ducts 1500 E from an adjacent ventilation grille 600 F under a balcony (*) 300 G under a window 600 H under a ventilation grille 600 I from a recess in the building 300 J from a corner of the building 300 K from the ground 2500 L from a vertical or horizontal duct or outlet (**) 300 M from a frontal surface at a distance of 3 metres from the fume outlet 2000 N as above, but with an opening 3000

(*) Providing the width of the balcony is not over 2000 mm. (**) If the pipe is made of materials sensitive to the action of the flue gases, this distance should be over 500 mm. Note: Spanish l aw also stipulates that the end of the exhaust duct must be at a distance of at least 400 mm from

any air intake opening, and from the wall.

Minimum distance

mm

IMPORTANT: All accessories used for combustion product removal and air intake should be

those supplied by TRIANCO.

5.2.- ø80 / ø100 (type C53) dual duct system for combustion product removal and air intake

For this type of boiler, combustion product removal and air intake take place through separate Ø80/100 mm mm ducts, using the Ø80/100 Kit, code CGAS000265. TRO Evolution BH boilers come equipped with this type of extraction, by default.

15 metres is the maximum length of pipe that can be installed in the TRO Evolution BH model, which is the maximum when adding up the metres of the air intake duct and the metres of the combustion product removal duct. For every horizontal metre, the available length is reduced by 2 metres and for every 90° bend, or two 45º bends, it is reduced by 1m.

It is recommended to fit the removal pipe in a slightly upwardly-inclined direction, at around 2º - 3º, thus preventing any water and condensation from dripping out.

5.3.- Changing from dual duct fume removal to coaxial fume removal

The TRO Evolution BH boiler has a Ø80 dual duct system for combustion product removal and air intake. If you prefer the combustion products to be removed by means of a Ø80/125 coaxial tube, you may use the Ø80/125 coaxial tube adaptor kit (supplied to order), code CGAS000213 + Code CGAS000222.

Adapter for coaxial pipe 80/125

ode CGAS000213 + Code CGAS000222

The changeover may be made with two different assembly configurations:

1. Output towards the back: simply remove the combustion air intake from the boiler,

unscrewing the three screws holding it in place, mount the adaptor on the fume outlet towards the rear, and use the flexible air inlet tube to connect it to the adaptor T.

2. Side or top output: the procedure is the same, but for side mounting of the adaptor kit a

90º Ø80 elbow (code CGAS000147) needs to be fitted before the adaptor at the fume outlet.

The two configurations are shown in the figures below:

5.4.- Concentric horizontal duct for combustion product removal and air intake ø80-125 (type C13)

Combustion product removal and air intake can be made using concentric Ø80 mm pipes for combustion product removal and Ø125 mm pipes for air intake, using the 1m Ø80-125 horizontal outlet kit, code CGAS000189.

The maximum length in a horizontal direction from the boiler, including the kit terminal, is 8 metres (TRO Evolution 20 BH) and 6 metres (TRO Evolution 30 BH). Each 90° elbow, or two 45° elbows, will reduce the available length by 1 metre.

It is recommended to fit the pipe in a slightly upwardly-inclined directi on, at around 2º - 3º, to prevent any water or condensation from dripping out.

6.- OPERATION

6.1.- Boiler functioning

Set the control thermostat and the room thermostat (if applicable) to the desired temperature. Move the main switch to the "I" position and the summer-winter switch to the Winter position "". The burner and the pump will begin to function until the installation reaches the pre-selected temperature of the control thermostat (or the room thermostat, if the unit has one). When the temperature in the installation drops, the burner will start up again, running the heating cycle.

6.2.- Operating with a Sanit hot water tank (optional)

The TRO Evolution BH boiler may be installed together with a hot water tank from the TRIANCO Sanit range, to obtain domestic hot water. For correct hydraulic installation,

carefully follow the assembly and connection instructions enclosed with the hot water tank. The boiler is provided with a switch to select summer position or winter position. Using this

switch we may choose:

- Summer Position ☼: in this position, the boiler only attends to the needs of DHW

production, lighting the burner and the hot water tank loading pump (summer pump) until the accumulated DHW temperature reaches the regulated temperature in the thermostat of the hot water tank. When the DHW temperature is reached, the burner and the summer pump will stop.

- Winter Position : in this position, the boiler attends to the needs of DHW and the heating

system, giving priority to DHW.

7.- SAFETY CUT-OUTS

The boiler has three types of safety cut-outs:

7.1.- Excessive temperature safety cut-outs (Thermostat TS)

This cut-out is indicated by the pilot light for blocking due to temperature. This occurs when the boiler exceeds a temperature of 110ºC. To restart, press the button on the safety thermostat after first removing the button cover.

7.2.- Excessive fume temperature safety cut-out (Thermostat TH)

This cut-out is indicated by the pilot light for blocking due to temperature. This occurs whenever the temperature of the fumes exceeds 110ºC. To restart, press the button on the safety thermostat after first removing the but ton cover.

7.3.- Burner cut-out

This cut-out is indicated by the pilot light for blocking of the burner. This occurs as a result of an anomaly in the burner or in the fuel installation. To unblock it, press the illuminated button that lights up on the burner.

NOTE: If any of these cut-outs occur repeatedly, call your nearest official Technical Assistance Service.

page -14

8.- CLIMATE CONTROL (OPTIONAL) :

The TRO Evolution BH boiler comes prepared for the installation of a Lago BVS climate control system.

B: Action on burner. V: Action on mixing valve. S: Action on domestic water.

The operating instructions and electrical connections are found in the packaging of the boiler.

9.- SHUTTING DOWN THE BOILER

To stop the boiler, simply turn the master switch to "O". To stop the central heating mode and leave only the DHW mode running, set the general

switch to the summer position "☼".

10.- START-UP

Before beginning the start-up process of the boiler, check that:

- The boiler is connected to the mains.

- The installation has been filled with water (the manometer should indicate a pressure of 1

- 5 bar).

- The fuel reaches the burner.

- The isolation valves are open, if there are any installed.

- The room thermostat is set to the desired temperature.

- The boiler room has effective and free ventilation (ventilation based on 0.5 dm

minimum).

To start-up the boiler, position the main switch and the room thermostat to the desired temperature.

2

11.- FIRST START-UP

For the guarantee to be valid, the boiler must be started up for the first time by an official TRIANCO Technical Assistance Service. Before beginning the start-up process, the following

must be complied with:

- The boiler must be connected to the mains.

- The installation must have been filled with water (the manometer should indicate a

pressure of 1 - 5 bar).

- The fuel must be reaching the burner at a pressure of no more than 0.5 bar.

page -15

12.- DELIVERY OF THE SYSTEM

After the initial start-up, the Technical Assistance Service will explain to the user how the boiler functions, making any observations they consider relevant.

The installer is responsible for clearly explaining to the user the functioning of any control or regulation device forming part of the installation but not supplied with the boiler.

13.- BOILER MAINTENANCE

To maintain the boiler in perfect working order, a yearly service should be performed by personnel authorised by TRIANCO.

13.1.- Cleaning the boiler

To maintain the boiler in optimal operating conditions it is recommended that an annual cleaning be undertaken of the combustion chamber, the fume outlets and the condenser. A cleaning brush of a suitable size for cleaning the inside of the exhaust ducts i s supplied with the boiler for this purpose. This brush is located at the rear of the boiler, beside the condenser.

The combustion chamber and exhaust ducts should not be cleaned using chemical products or hard steel brushes. After any cleaning operation has been carried out, it is important to

run several ignition cycles to check all the elements are functioning correctly. For correct cleaning, the following recommendations should be carefully observed:

Cleaning the boiler body

- Open and remove the outer door of the boiler.

- Remove the burner by unscrewing the fixing nut on the top of the burner.

- Remove the combustion chamber door and the exhaust duct cover, unscrewing the six

fixing nuts around them.

- Clean the exhaust ducts on the cast body, using the cleaning brush supplied with the

boiler.

- Clean the boiler combustion chamber. We recommend using a soft brush for scrubbing

the combustion chamber surfaces, and a blower to remove the flakes.

- After cleaning, replace the combustion chamber door, the exhaust duct cover, the

burner and the outer door of the boiler.

Cleaning the condenser

- Open and remove the top cover of the boiler to access the condenser on the rear of the

boiler body.

- Open the top cover of the condenser to access its exhaust ducts. To open this cover,

release the two side closures, turn the locking plate anti-clockwise and pull the cover upwards to remove it.

- Remove the exhaust deflectors inside the exhaust outlets.

- Clean the exhaust ducts using the cleaning brush supplied with the boi ler. Any scale will

fall through the condensation drain and onto the lower condenser cover. It is advisable

page -16

to pour water into the top of the condenser for a more effective cleaning. This water will be automatically discharged through the condensation drain.

- To clean the outer part of the condenser cylinder, remove the three screws and then

remove the metal ring. Take out the seal and use the brush to clean it. Next, put the components back in place again and replace and tighten the three screws and the metal ring.

- If the lower condenser cover needs cleaning, remove the side cover of the boiler to

access it. Firstly remove the bracket holding it in place and pull on it to open it. Then pull the lower cover down to open and clean it.

- After cleaning, replace the fume deflectors, the top condenser cover and the top outer

cover of the boiler. Then put the cleaning brush back inside the boiler.

- The condensation siphon should be cleaned once a year. To do this, remove it and wash

it in soapy water. Replace the siphon after cleaning.

13.2.- Boiler water characteristics

In areas with water hardness over 25-30ºF, treated water must be used in the heating installation to avoid any lime scale deposits on the boiler. It should be noted that even a few millimetres of scale will greatly reduce the boiler's heat conductivi ty, causing a major drop in performance.

Treated water must be used in the heating circuit in the following cases:

- Very large circuits (containing a large amount of water).

- Frequent filling of the installation.

If repeated partial or total draining of the installation is necessary, we recommend filling it with treated water.

page -17

13.3.- Condensate drain-off

The drain for boiler condensate must not be altered and must be kept clear of obstructions. Annual maintenance of the condensate trap is recommended to avoid obstructions that hinder the discharge.

If a neutralisation system is installed i n the condensate drain, it is essent ial to conduct annual maintenance of the system, following the instructions of the manufacturer of the neutralisation system.

17.- BURNER

17.1.- Assembly

Secure the burner support to the boiler. then fix the burner to the support. This will allow the correct tilt of the flame tube towards the combustion chamber. Fit the intake and return pipes.

17.2.- Burner start-up

First place a manometer and a vacuum gauge and prepare the combustion analyser. The "Domestic" burner is equipped with a self-extracting pump to enable fuel intake from a

tank installed at a lower level than the burner, providing that the pressure difference measured with the vacuum gauge at the pump does not exceed 0.4 bar (30 cmHg).

Make sure there is fuel in the tank, that the oil valves are open and that voltage is reaching the burner. Turn on the master switch. Unscrew the air bleed screw (manometer point). Then, when the valve opens, remove the photocell sensor and move i t towards a light source until the oil comes out. Disconnect the burner and screw the bleed screw back in.

17.3.- Adjusting the combustion conditions

As each particular installation has a different combustion circui t, it is essential to adjust the combustion conditions of each boiler. In order for the guarantee to be valid, the burner must be adjusted by an official TRIANCO Technical Assistance Service.

Observe the flame. If there is insufficient combustion air, it will be dark in colour and will produce smoke, rapidly obstructing the flue outlet.

On the contrary, if there is an excess of combustion air, the flame will be whitish or bluishwhite in colour. This will reduce the performance of the boiler and it will fail to comply with anti-pollution standards, and the excess air may also hinder the ignition process.

The flame should be orange in colour. If the shape of the boiler makes it difficult or i mpossible to observ e the flame, the combustion

air flow can be regulated by observing the smoke comi ng out of th e flue. If the smoke is dark in colour, more air will need to be provided to the burner, or if it is a very whitish colour, the air in the burner will need to be decreased until no smoke at all is observed.

If you have a device for determining t he composition of the combustion gases, this will be the best guide for flame adjustment. If not, simply follow the above indications.

To adjust the air and burner line conditions, carefully follow the instructio ns given below.
