Pellet burners need regular cleaning and therefore boiler construction must allow easy opening of
boiler’s door without removing the burner. The minimum size of opening in boiler’s door depends on the
position of door hinges. Figure 6 below illustrates the situation. Point C is the critical point.
In order to keep door width minimum and boiler’s door opening small, a double hinge solution
can be used. As double hinges add another degree of moving-freedom, door must be fastened on both
sides. Slide-out doors with guide rails is also an option.
2.2 Burner installation
Burners are delivered to customer in fully put together. Before mounting the burner to boiler it has to be
disassembled i.e. bricks have to be removed and burning chamber separated from burner and air box.
Mount the burning chamber on the
inner side of the boiler door.
Double hinges
Boiler’s firebox depth L must be at least 2,5
times longer than the length of burner’s
burning chamber. Thus minimal length of
the firebox L for PV700 has to be 1500 mm
and for PV1000 1800mm. The height of
firebox must leave at least 100 mm space
(H1) for ash below burning chamber.
Minimum dimensions: L1 ≥700mm; H
≥650mm. See Figure 5.
