Vitoflex 300-RF Installation & Operating
Flue Gas Cyclone
The flue gas cyclone minimizes dust emissions and is
designed as a multi cyclone with axial function. The
de-duster is fully insulated and has three covers for
cleaning. The flue gas cyclone for 300 RF is an option,
and is not generally required when burning pellets but is
recommended when burning chips.
The crude gas chamber is cleaned via the side cleaning
cover. The clean gas chamber is cleaned via the upper or
back cleaning cover (unused blower connection).
The ash box has a carriage and is connected to the de-
duster with quick-action fasteners. It can easily be pulled
out for emptying. The blower can be installed either
on the side or the top.
