1.1.10. WATER CONNECTIONS

DANGER

Make sure that the tubes of the water and heating unit are not used as grounding system for the electrical unit. There are not suitable for such use.

WARNING

To prevent voiding the warranty and to ensure the proper operation of the boiler, wash the unit (if possible when hot) with suitable descaling solution to remove the impurities coming from tubes and radiators.

WARNING

If the boiler is installed in a hydrostatic position lower than those of the user devices (radiators, fan coils, etc.), mount the shut-off valves on the domestic water heating circuit to ease the performance of the maintenance operations if necessary to only empty the boi ler.

WARNING

When connecting the equipment to water supply, avoid excessive bending and recovery operations from improper positioning that may damage the tubes causing leaks, malfunction or premature wear.

WARNING

In order to avoid any vibrations and noises, do not use tubes with small diameters or elbows with small radius and significant cut-off of the passage sections.

DOMESTIC CIRCUIT

In order to prevent limestone build-up and damages to the domestic water heat exchanger, the hardness of the domestic supply water should not exceed 8.4° dh (degrees hardness). However, please check the characteristics of the water used and install suitable treating devices.

The heat exchanger coil cleaning frequency depends on the hardness of the supply water and on the presence of solid residues or impurities inside the water that are often present in case of recently installed plants. Based on the characteristics of the inlet water, you should install suitable water

treatment devices, for residues presence. Please install an inline filter.

The pressure of the cold inlet water should be between 7.2 psi (0.5 bar) and 150 psi (10.34 bar). In case of greater pressure values, please install a pressure reducer upstream from the boiler.Please refer to local jurisdictions on the requirements for cold inlet water pressure.

HEATING CIRCUIT

In order to avoid any scale or deposits on the primary exchanger, the hardness of the heating circuit inlet water should not exceed 14° dh (degrees hardness). However, please check the characteristics of the water used and install suitable treatment devices.

To protect the central heating system from damaging corrosion, flakes or deposits it is important to clean the hydronic system using cleaners such as Fernox F3 Cleaner. For long term protection against corrosion and deposits, the use of inibitor (such as Fernox F1 inhibitor) is required after cleaning and flushing of the hydronic system. It is important to monitor the concentration of the inibitor during commisioning and during servicing of unit.

WARNING

Failure to clean the central heating system or add adequate inibitor invalidates the compliance warranty.

Connect the boiler safety drains (heating circuit safety valve) to a discharge funnel. The manufacturer is not responsible for any floods due to safety valve opening in case of unit excessive presure build up.

WARNING

In case the boiler is installed as part of a low temperature circuit, please install a safety thermostat on the heating flow, which can stop the boiler activity in case of high heating flow temperature. The company assumes no liability for damage caused to persons or for failure to comply with these instructions.

1.1.11. PRESSURE RELIEF VALVE KIT

To complete the installation of the boiler, you must install an approved 3/4”, maximum 30 PSI (2 bar) pressure relief valve on the heating return.

A hydronic kit equipped with hydronic connections and safety valve (see ‘VS’ fig. 9) is available and supplied by RADIANT.

ATTENTION

The pressure relief valve MUST TO BE

INSTALLED in any case.

ATTENTION

The pressure relief valve should be placed as close to the boiler as possible. No other valve should be placed between the pressure relief valve and the boiler.

DANGER

Improper installation of the pressure relief valve may result in property damage, personal injury, or death. Follow all instructions and guidelines when installing the pressure relief valve. The valve should be installed only by a licensed professional.

When installing the valve, follow these guidelines:

› Direct the discharge piping of the pressure relief

valve so that hot water will not splash on anyone or any nearby equipment.

› Attach the discharge line to the pressure relief

valve and run the end of the line to within 6-12” (150-300mm) of the floor.

› Ensure that the discharge line will allow free and

complete drainage without restriction. Do not install a reducing coupling or other restriction on the discharge line.

1.1.12. SYSTEM FILLING

WARNING

For system filling use only clean tap water.

WARNING

If the system is filled by adding ethylene glycol-type chemical agents it is suggested to install a system fender on the hydronic system in order to separate the heating circuit from the domestic circuit.

Before powering up the boiler, fill the system as follows:

1. Make sure the circulator is not blocked;

2. Slightly loosen the cap of the circulator air

eliminator (1-fig. 10) to release the air from the system;

3. Slightly loosen the cap of the air eliminator

placed on the top of the condensing block (fig. 12) to release the air form the top of the system;

4. Open the feeding tap “R” (fig. 11);

5. Release all the air;

6. Use pressure gauge “M” (fig. 11) to make sure

that the system pressure reaches 1.2 bar (fig.

8. Unscrew the circulator cap (2-fig.10) to release any air bubbles and close it to prevent water leakage;

9. Open the air relief valves of the radiators and check the air removal process. When the water starts to leak close the radiators air relief valves.

10. If after performing these operations you observe a decrease of the water pressure inside the system, open once again the loading tap “R” until the pressure gauge indicates the value of 1.2 bar (fig. 13)

1.1.13. FILLING THE CONDENSATE

COLLECTION SIPHON

Before starting the boiler you have to fill the condensate collection siphon in order to avoid fuel back up through the siphon.

Fill the condensate collection siphon as follows (see fig. 14):

› Unscrew the “T” cap from the siphon, fill three

quarters of the the siphon with water and screw the “T” cap back in;

› Connect the dedicated flexible condensate

draining tube “P” to a waste disposal system. The condensate can be drained directly in the sewer system by inserting an easily serviceable siphon.

WARNING

After the fir st months of boiler operation, it is recommended to clean the condensate trap, to eliminate possible deposits coming from the first flow of the condensate inside the boiler technical components. These deposits could cause a malfunctioning of the trap.

INSTALLER

CONDENSATE DRAIN

The boiler produces a significant amount of condensate during operation. This condensation has an acidic pH of 3-5. Follow all local codes and regulations when disposing of condensate from the boiler.

The project engineer should consider the possibility of installing systems to eliminate the acidic condensation, according to system power and buildings’ use.

The system should be designed to avoid the condensate freezing. Before the boiler commissioning, check the correct condensate flow.

WARNING

Check before connecting the condensate

trap to the drain pipe, for the proper gradient of boiler as described in paragraph “1.1.8 POSITIONING AND MINIMAL TECHNICAL SPACES”.

WARNING

Properly connect the siphon condensate from the boiler to a drain system having adequate slope. Where possible, you should make this connection using transparent tubing to check for proper condensate drainage and avoid stagnation that could cause hazardous backflow of the condensate into the boiler.

To connect the condensate drain use only corrosion-resistant material for the drain line.

CONDENSATE NEUTRALIZER KIT

The condensate neutralization system neutralizes the condensate created by the products of combustion.

Acid condensate, introduced into the neutralization box, follows a two-step set course. First phase: nitrates and sulphates filtration through active carbons contained in the first part of the carbon site pipe. In the second phase the pH rises.

The acidity of the condensate can be controlled through the use of appropriate tools for the determination of Ph, such as the litmus paper.

Neutralized condensate can then be routed to the drainage system.

MAINTENANCE

The pH value of the condensate after the neutralizer must be in between <5,5 – 9,5>.

Every six months, you need to determine the pH of the condensate treated in the neutralizer. Litmus paper or a digital instrument can be used to measure the pH level.

Neutral point is on the 6,8-7 value; in case of lower value the condensate is acid, in case of a higher value it is basic.

If necesssary, replace the active carbon and the reagent granulate.

Shutoff the voltage from the main switch.

› Remove the front casing of the boiler (see 2.2.13

ACCESSING THE BOILER); unscrew the screws and remove plate “A” (see fig. 16-B).

› After removing the plate, connect the electrical

cables to terminal “B” (see fig. 16-B):

· For the external temperature Probe connect the two non-polarized conductors to the SeSe contacts.

· For the environment Thermostat or Remote control, first remove the bridge on the TaTa contacts and then connect the two nonpolarized conductors to the Ta-Ta contacts.

After performing these operations, remount plate “A” and the front casing.

NB: In case of simultaneous presence of external probe and

remote control, the modulation board only sends the external

temperature value to the remote device without using it for

modulation.

The communication between board and remote control takes

place independently from the boiler’s operating mode and after

establishing the connection, the used interface on the board is

disabled and the display shows the symbol ‘ ’.
