Abstract (en)
[origin: EP0400757A2] The apparatus comprises a furnace which is provided on one side, preferably at the bottom, with one or more burners (6) which can be ignited by a pilot light (22), and at the top with a heat exchanger (1) covered by a top wall (12) connecting a flue (14). A self-acting valve (16) is mounted in the flue, which valve is opened when a fan (30) arranged in the air supply duct or the flue rotates at a high speed, and closed, for instance by means of a weight (18) or a spring, when said fan rotates at a low speed. An air passage (31) may be provided in the flue downstream of the self-acting valve to create a by-pass effect.
