<p>A gas or oil fired enclosed boiler (1) comprises a base (2), a top (3), a main rear tank (4), a main front tank (5) and a pair of main side tanks (6, 7) which define an enclosure through which flame and hot gases are led from a burner (12) to an exhaust flue (16). The top (3) includes a removable cover for cleaning access. Four baffle assemblies are provided in the boiler. Adjacent transverse baffle plates (30, 31, 32, 33) are longitudinally spaced-apart to define interconnected transverse passageways. Deflectors (50, 51, 52, 54) are welded to each baffle plate (30, 31, 32, 33) and direct flame and hot gases against the water-carrying surface of the boiler. The baffle plate assemblies are removable through the top of the boiler for cleaning.</p> |
