TERMOROSSELLA PLUS DSA / FORNO DSA – TERMONICOLETTA DSA / FORNO DSA18 7197100 - IT - EN - DE - FRboiler 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 avoidunpleasant 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 hasto be faced by adding antifreeze substances.3. FIRE-FIGHTING SAFETY MEASURESWhen 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 componentsflammable and sensitive to heat (furniture, wood sheathings, fabrics. etc.) and from materials with flammable structure (seePicture 4 at page 55-A). All the minimum safety distances are shown on the product data plate and lower values must notbe 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 ofless than 100 cm. This distance can be reduced to 40 cm where a rear-ventilated, heat-resistant protection device is installed infront 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 inflammablematerial, such as moquette, parquet or cork etc., must be replaced by a layer of no-inflammable material, for instance ceramic,stone, glass or steel etc. (dimensions according to the local regulations). The base must extend at least 50 cm at the front and atleast 30 cm at the sides, in addition to the opening of the loading door (see Picture 4 at page 55 - B).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 asealed, fire resistant container. The Product must never be on in the presence of gaseous emissions or vapours (for example glue forlinoleum, 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 protectiveclothing 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.3.1. FIRST-AID MEASURESShould any fire arise in the stack or in the flue:a) Close the feeding door.b) Close the registers of combustion airc) Extinguish the fire using carbon dioxide fire-fighting means (CO2 dust).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.4. DESCRIPTIONDefinition: thermo-product according to EN 13240.La Nordica thermoheating products are suitable for heating homes using a centralised heating system made up from radiators or heatconvectors entirely or partially replacing the traditional gas or diesel oil boiler.The appliance is composed of painted and galvanised sheet steel and cast iron.The fireplace is found inside the boiler, is built in 4 mm thick steel and is reinforced using welded nails. A swivelling, removable grid is foundinside the fireplace.The water in the heating system circulates in the boiler, which absorbs the heat produced in the fireplace.The ceramic glass window (resistant up to 700°C) of the door provides a lovely view of the burning flames and prevents sparks and smokefrom getting out.Room heating takes place:a) by radiation: the heat is radiated into the environment through the panoramic window and the hot external surfaces of the thermo-product;b) by conduction: radiators or heat convectors of the centralised system fed by hot water produced by the boiler.The device is equipped with registers of primary and secondary air.A- PRIMARY air registerWith the primary air control (Picture 5 at page 55 - 1A) is adjusted the passage of air through the ash drawer and the grate in the fueldirection. The primary air is necessary for the combustion process. The ash drawer must be regularly emptied, so that the ash does not
