<p>The invention relates to a boiler meant to produce hot water. The boiler comprises a burner above which there is placed a primary heat exchanger, both enclosed in a casing above which there is located a fan which draws off the gases resulting from the combustion and directs them towards a secondary heat exchanger, above the primary heat exchanger there being located some deflecting devices to direct and distribute the combustion flue gases before they are drawn off by the fan, so as to contribute to the transfer of heat from gases to the water or the thermovector fluid, the deflecting devices (13) comprise a partially flat deflecting body (15) positioned below the cover (5) of the casing (4) enclosing the primary heat exchanger (3) and being integral with the above-mentioned casing, the partially flat deflecting body (15) which present at one of its ends an aperture (19), said aperture being positioned in the proximity of an aperture (6) in said cover (5), and comprising two positions (16 and 17) positioned at an angle from one another.</p> |
