Cleaning The Vacuum Module; Servicing The Rotary Lock Valve - Viessmann VITOLIGNO 300-C Installation And Service Instructions Manual

Cleaning the vacuum module

Clean the vacuum module at least once per heating
season, subject to the dust content of the pellets.
Note
Using a pellet dust extractor (accessory) can signifi-
cantly reduce the maintenance effort for the entire vac-
uum system.
The pellet dust extractor separates dust particles from
the return air of the vacuum system and discharges
them into a dust container.
