2.0. BOILER EKO-CUP SV3 2500 COMPONENT PARTS

3.0. IN GENERAL

The new boiler for central heating is intended for firing with fuel oil extra light EKO-CUP SV3 2500 (FOEL) and gas. The boiler has a modern construction and design regarding to the designed capacity. It is made out of controlled high quality materials, welded with the most modern technology. The boiler EKO-CUP SV3 2500 is approved and tested in accordance with EN standards and fulfills all special requirements for connection to the central heating installation.

3.1. BOILER DESCRIPTION

The boiler EKO-CUP SV3 2500 is a triple pass flue gas flow system steel hot water boiler. Flue gases flow from the combustion chamber into the tube of second pass and then into the tube of third pass, where turbulators are placed. Turbulators enable better transmission of the thermal energy to the boiler water and also enable the fine flue gas outlet temperature control.

4.0. BOILER DELIVERY

The boiler EKO-CUP SV3 2500 is delivered with outer boiler panelling made of plastificated sheet metal and thermal mineral wool insulation. Afterwards it is possible to build in one or two additional. control units for the heating control of one or more boiler and heating circuits.

OBLIGATORY ACCESSORIES (ORDERED ADDITIONALLY):
– Basic boiler controller EKO-CUP S3/V3 – REG – 100 °C
or
– Basic boiler controller CUPREG-Touch – 100 °C

5.0. BOILER MOUNTING

It is recommended to mount the boiler in the boiler room, which has to be built EKO-CUP SV3 2500 to in accordance with undisturbed serving and easily the boiler heating power, normal operation condition , accessible boiler, burner and boiler equipment. The boiler must be placed on the 5 to 10 cm high concrete slab above the ground. lab edges must be protected by a frame (50x50x5). Then iron made boiler must be positioned in order to enable supervision during boiler operation, cleaning and maintenance. Due to transport of the boiler into the boiler room, mounting of the thermal insulation has to be done after the boiler is properly placed in the boiler room as shown on the Figure 1.

Insulation mounting

PROCES OF PANELLING ASSEMBLY ON THE BOILER:

1. Put side panels onto bracket-X in the order shown on the figure – panels (1) to (12) (panels (1) to (6) are the same and panels (7) to (12) are the same).
2. Attach the top front panel (13) with two M8x35 screws to the boiler and do the same with the top rear panel (14).
3. Screw the two 3,9×13 screws slightly (not to the bottom) on the left and right side of the top front plate (13).
4. • Remove the perforated part (R) on the upper front panel (13), depending on the desired side of the controller.
5. Depending on the installation position of the boiler controller (possible installation: left or right side of the boiler), open one of the perforated holes (R) on the upper panel (13) and pass the boiler rcontroller sensors through it and all of them except the flue gas sensor (if the boiler controller have it) put it in the sleeve for the boiler sensors (see figure 2), and put the flue gas sensor (if the boiler controller have it) through the intended hole on the back side of the boiler casing (see figure 2) and put it in the sleeve for the sensor on the boiler chimney (see figure 2). Place the regulation on the 3.9×9.5 screws and tighten the screws completely (to the bottom).
6. Put the top right panel (15) on the boiler.
7. Put the top left panel (16) on the boiler.
8. Attach the connection panel and back panels (18 to 21) to the top rear panel and the side panels (1, 4, 7 and 10) with 4,2×30 screws. Attach the connection panel (V) to the panels (18 and 19).
9. Side panels (3, 6, 9 and 12) attach to the door protection brackets (22 and 23) with 4,2×30 screws and then attach door protections to those brackets.

• Controller (EKO-CUP S3/V3 – REG – 100°C or CUPREG-Touch – 100°C – additional equipment) it can be placed on the left or right side of the boiler.

6.0. CHIMNEY

Correctly calculated and performed chimney is a precondition for a safe boiler operation and economic heating results. The chimney must be well thermal insulated, gas-impermeable and smooth. On the lower part of the chimney a cleaning door must be installed. A walled chimney must be three-layered with a middle mineral wool insulation layer. The thickness of the insulation should be at least 30 mm thick if the chimney is mounted inside the building and 50 mm thick if is mounted outside the building walls. The inner diameter of the chimney depends upon the actual chimney height and the boiler heating power. The flue gas temperature on the chimney exit has to be at least 30°C higher than the condensation temperature of combustion flue gases.
To ensure safe, reliable, efficient and long-lasting boiler operation, the chimney must be calculated in accordance with the norm EN 13384-1 (software such as KESA Aladin or similar).

7.0 CONNECTION TO THE CHIMNEY

The flue gas tube between the boiler and the chimney has to be mounted under an inclination between 30 to 45° (Figure 3). To prevent the entering of condensing fluid from the chimney into the boiler it is necessary and important to mount the flue gas tube 10 mm deeper into the chimney. It is highly recommended to insulate the flue gas tube, especially if is longer than 1m. For easier flue gas tube cleaning the tube must have an opening (Figure 4). Connections of the flue gas tube on the boiler and chimney must be properly made and sealed. For easier chimney cleaning we recomend the distance at least 1m between the boiler and the chimney or wall.

8.0. FRESH AIR OPENING

Every boiler room must have a correctly calculated opening for fresh air inlet regarding to the boiler heating power. The diameter of the fresh air opening must be calculated:

A = 6.02 Q

A – surface of the opening in cm2
Q – boiler heating power in kW

The opening must be protected by a net or grid.

9.0. CONNECTION TO THE INSTALLATION

All installation works must be done in accordance with valid national and European standards. Before boiler connection to the heating installation it is necessary to clean all tubes in the system from dirt layers. These actions prevent boiler overheating, noise in the heating system, disturbances on the pump and mixing valve. In a closed heating system, it is obligatory to install certificated safety valve with opening overpressure set on 6 bar. Safety and expansion lines must not have any shut-off elements. Drainage of heating water flowing through the safety valve is conducted direct to the sewerage. During the water filling into the heating system it is necessary to open the mixing valve if it is mounted and to air-vent the boiler and the heating system. Boiler connection to the central heating installation must be performed as it is shown on Scheme 1. and in accordance with the norm EN 12828:2012+A1:2014.

As it is shown on Scheme 1., the boiler must be connected to the heating system over hydraulic crossover and the boiler return flow protection must be performed with 3-way mixing valve with motor actuator, that will keep temperature above 60°C. Depending on configuration or controller, this motor actuator may have its own controller or it can be controlled by a boiler controller.

Boiler connection to the installation

9.1. WATER QUALITY

To prevent excessive limescale build-up of calcium carbonate on the boiler heating surfaces, its concentration must be below the permitted maximum values mentioned in the following table:

• the flue gas tube is properly sealed and the boiler is connected to the power supply

• there is no water leakage

• the filling/drainage valve in the system is closed

• the complete installation is air-vented

• the safety valve works properly (activate the safety valve and check if it works properly)
