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 piping 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 install 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.

- The condensation pipe must lead to a drain outlet

The condensation pipe must lead to a drain outlet, as the Jaka HFD Condens is a condensing

The condensation pipe must lead to a drain outletThe condensation pipe must lead to a drain outlet boiler and a large amount of water may be generated. This connection must be made in compliance with the regulations for draining off condensation water to the drainage system.

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

To fill the installation, open the fill valve until 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 installation using the air bleed valves provided. Close the fill valve after filling.

Adapter for coaxial pipe ∅80/125

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.

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

12.112.1

Cleaning the boilerCleaning 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 is 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

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

Cleaning the boiler bodyCleaning the boiler body

- Open and remove the outer door of the boiler.

DOMUSA TEKNIK.

DOMUSA TEKNIKDOMUSA TEKNIK

- 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

Cleaning the condenserCleaning 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 boiler. Any scale will fall through the condensation drain and onto the lower condenser cover. It is advisable 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.

Boiler water characteristicsBoiler 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 conductivity, 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.

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 in the condensate drain, it is essential to conduct annual maintenance of the system, following the instructions of the manufacturer of the neutralisation system.

16.216.2

Burner startBurner start

First place a manometer and a vacuum gauge and prepare the combustion analyser.

The "Domestic" burner is equipped with a self-priming pump, which allows the aspiration of fuel from a tank installed at a lower level than the burner, as long as the vacuum measured with the vacuum gauge in the pump does not exceed 0,4 bat (30cmHg).

The suction of fuel must never reach the bottom of the tank, always leaving a minimum distance of 10 cm to the bottom, if possible, the suction kit with float is recommended.

In installations that allow it, the fuel returns must be made to a recirculation filter with air purge, thus avoiding oxidations in the diesel pump.

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 it towards a light source until the oil comes out. Disconnect the burner and screw the bleed screw back in.

16.316.3

Adjusting the combustion conditionsAdjusting the combustion conditions

As each particular installation has a different combustion circuit, it is essential to adjust the combustion conditions of each boiler. In order for the guarantee to be valid adjusted by an official

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 bluish-white 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 impossible to observe the flame, the combustion air flow can be regulated by observing the smoke coming out of the 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.
