<p>The boiler has a frame (3) insertable into a niche (2) formed in a wall and provided with a combustion air inlet port (15), an exhaust gas venting port (16), a gas delivery union (10a), heating system delivery and return unions (11a, 12a), a cold water inlet union and a hot water outlet union. Wall ties (4) protruding from the frame (3) can be built into brickwork (1) surrounding the niche (2), guides (5a, 5b) are fixed inside of the frame (3), and a door (8) hinged to the frame (3) lies flush with the wall. The body (6) of the boiler has slides (7a,7b) for mounting on the guides (5a,5b) and is concealed by the door (8). Quick couplings (10,11,12,13,14) connect a gas duct (6a), heating system delivery and return ducts (6b,6c), and hot water outlet and cold water inlet ducts (6d,6e) of the boiler (6) to the respective unions (10a,11a,12a) provided in the niche (2). Connectors (17,18) rigidly coupled to a plate (19) connect the ports (15,16) in the niche (2) to respective openings provided in the body (6) of the boiler. <IMAGE></p> |
