FOCOLARE 80 IDRO CRYSTAL - DSA
The heat discharge coil must have one side connected to the water network (A -
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).

SYSTEM CONNECTION AND FILLING

Some examples, purely indicative of the installation, are reported at chapter INSTALLATION LAY-OUT, while the connections to the
thermoproduct are reported at chapter DIMENSIONS.
ATTENTION: The filling of the system must take place exclusively by the natural fall of the water from the open expansion tank
through the feed pipe in order to avoid that a too high water system grid pressure could change or cause the explosion of
boiler body.
During this phase, open all the bleed valves of the radiators to prevent the formation of air sacks, checking the outlet of water to avoid
unpleasant floodings.
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 sufficient thermal insulation, respect the minimum safety distance from objects or furnishing components flammable
and sensitive to heat and from materials with flammable structure (see CE MARKING INFORMATION -
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 flammable 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
of the whole component to protect;
c) If the product is installed on a no totally refractory floor, one must foresee a fireproof background. The floors made of inflammable
material, such as moquette, parquet or cork etc., must be replaced by a layer of no-inflammable material (size according to
regional law) In case the replacement of the floor is not possible, the appliance shall be placed on a minimum 12 cm thick
slab made of stone or concrete (see
The ash drawer must always be inserted when the appliance is in operation.
The solid combustion residues (ashes) must be collected in a metal container that is hermetically sealed and fire 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 flammable
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 flue, a flue fire is possible.
3.1.

FIRST-AID MEASURES

Should any fire arise in the stack or in the flue:
a) Close the feeding door.
b) Close the registers of combustion air
c) Extinguish the fire using carbon dioxide fire-fighting means (CO
d) Seek immediate intervention of FIRE BRIGADE.
DO NOT EXTINGUISH FIRE USING WATER JETS. When the flue does not burn any more please arrange an examination by a specialist
in order to find 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 flammable material
must not come in contact with temperatures higher than 65 °C.

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