The location of air inlets in relation to the high ventilation openings must ensure that air is renewed in the entire volume of the boiler room. CONNECTON TO A CHMNEY The high performances of modern boilers and their use under specific conditions related to changes to burner technologies (for example, operation at modulated low temperature) result in very low flue gas temperatures. This requires: 1- The use of chimney flues designed to enable the flow of condensates, which may result from such operating modes, in order to prevent the risk of damage to the chimney. - The installation of a bleeding T at the foot of the chimney. The use of a draught moderator is also recommended. n order to avoid damage to boilers, it is necessary to prevent the contamination of combustion air by chloride and/or fluoride compounds, which are particularly corrosive. These compounds are present, for example, in aerosol spray cans, paints, solvents, cleaning products, washing powders/liquids, detergents, glues, snow clearing salts, etc. t is therefore necessary: - To avoid sucking in air discharged from premises using such products: hairdressers, dry cleaners, industrial premises (solvents), premises containing refrigeration systems (risk of leaking refrigeration fluid), etc. - To avoid the storage of such products close to boilers. Please note that, if the boiler and/or its peripherals become corroded by chloride and/or fluoride compounds, our contractual warranty cannot be invoked. The table below contains the minimum dimensions of the flue required for each model of boiler to ensure sufficient draught at the nozzle. However, care must be taken to comply with any applicable national or local regulations. Connection to the chimney: The cross section of the pipe used to connect the boiler nozzle to the flue must be at least equal to that of the nozzle and the conduit must be as direct and as short as possible.
