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.
FIRE SAFETY
When installing the product, 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 (furniture, wood sheathings, fabrics. etc.) and from materials with flammable structure (see
Picture 4
- A). 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 flammable or heat-sensitive objects or material at a distance of
less than 100 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 non totally refractory floor, one must foresee a fireproof background. The floors made of inflammable
material, such as moquette, parquet or cork etc., must be covered by a layer of no-inflammable material, for instance ceramic,
stone, glass or steel etc. (size according to regional law). The base must extend at least 50 cm at the front and at least 30 cm at
the sides, in addition to the opening of the loading door (see
d) No flammable components (e.g. wall units) must be present above the product.
The Product must always operate exclusively with the ash drawer inserted. The solid combustion residues (ash) must be collected in
a sealed, fire resistant container. The Product must never be on in the presence of gaseous emissions or vapours (for example glue
for linoleum, petrol etc.). Never deposit flammable materials near the Product.
During combustion, thermal energy is released which leads to considerable heating of the surfaces, doors, handles,
controls, glass parts, the flue gas pipe and possibly the front part of the appliance. Avoid contact with these elements
unless using suitable protective clothing or accessories (heat resistant gloves, control devices).
Ensure children are aware of these dangers and keep them away from the furnace when it is on.
When using the wrong fuel or one which is too damp, due to deposits present in the flue, a flue fire is possible.
IN A EMERGENCY
If there is a fire in the flue connection :
a) Close the loading door and the ash drawer door
b) Close the comburent air registers
c) Use carbon dioxide ( CO
d) Request the immediate intervention of the Fire Brigade
DO NOT PUT OUT THE FIRE WITH WATER.
When the flue stops burning, have it checked by a specialist to identify any cracks or permeable points.
