La Nordica Focolare 80 Idro Crystal D.S.A [19/76] System connection and filling

The heat discharge coil must have one side connected to the water network (A - Picture 1 at page 64 - chap. Technical data sheets) and

the other rot drainage network (C). When the safety temperature is reached, the automatic thermal discharge valve DSA, the bulb of which

is to be connected to attachment B, enables the intake of cold water in the boiler coil, discharging the excess heat out of pipe C towards a

conveniently installed drain. Cooling circuit upstream pressure must be at least 1,5 bar.

WARNING: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions of these

instructions or when it uses additional products not suitable for this device (see chapter Thermostatic Valve VAST TECHNICAL

DATA SHEET).

2.5. SYSTEM CONNECTION AND FILLING

Some examples, purely indicative of the installation, are reported at chapter INSTALLATION LAY-OUT, while the connections to the

The watertight test of the installation is performed with the pressure of expansion tank open.

The installation must always be full of water even when the thermo-product is not used. During winter season the non use has

to be faced by adding antifreeze substances.

3. FIRE-FIGHTING SAFETY MEASURES

When installing the appliance, the following safety measures must be observed:

a) In order to ensure sufcient thermal insulation, respect the minimum safety distance from objects or furnishing components ammable

and sensitive to heat and from materials with ammable structure (see CE MARKING INFORMATION - Picture 8 at page 68). All the

minimum safety distances are shown on the product data plate and lower values must not be used.

b) in front of the furnace door, in the radiation area, there must be no ammable or heat-sensitive objects or material at a distance of

less than 80 cm. This distance can be reduced to 40 cm where a rear-ventilated, heat-resistant protection device is installed in front

The solid combustion residues (ashes) must be collected in a metal container that is hermetically sealed and re resistant. The appliance

must never be lit in the presence of gaseous emissions or vapours (for example: glue for linoleum, petrol, etc,). Do not place ammable

materials in the vicinity of the appliance.

During the combustion, thermal air is emitted by involving the heating of areas, door and glass hearth, of the door handles or controls,

of the smokes pipe and, in case, of the front part of appliance. Avoid to touch those parts without a protective clothing or without

accessory tools (gloves resistant to heat, control devices).

Ensure children are aware of these dangers and keep them away from the furnace when it is on.

Warn children that the device becomes very hot and that it must not be touched.

When using the wrong fuel or one which is too damp, due to deposits present in the ue, a ue re is possible.

3.1. FIRST-AID MEASURES

DO NOT EXTINGUISH FIRE USING WATER JETS. When the ue does not burn any more please arrange an examination by a specialist

in order to nd possible cracks and permeable points.

3.2. BEAM PROTECTIONS

Considering the irradiation of the hearth, it is necessary to be particularly careful in protecting the beams while designing your stack.

Consider the proximity of beams to the external surfaces of the hearth, on one side, and the irradiation of the glass door, usually very close

to the beams, on the other side. In any case, it has to be considered that the internal or lower surfaces of this beam in ammable material

must not come in contact with temperatures higher than 65 °C. Picture 3 at page 65 gives some examples of execution.

WARNING: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions of these

instructions or when it uses additional products not suitable for this device.
