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
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
2
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.
