Boiler cleaning and maintenance
Regular maintenance and cleaning of pellet boilers is necessary to ensure product functionality and long-
life operation.
Regular weekly cleaning consists of following operations (detailed steps are xplained in text below).
1. Emptying the ash from the bottom of the boiler (using the ash tray delivered with boiler)
2. Removing ash layers in the heating chamber if such
3. Cleaning the retort burner (round plate where pellets are falling in)
4. Cleaning the plate which is carrying the retort burner
5. Moving the bar in the heat exchanger of the boiler. This would force the ash to fall down from the
difficult-to-access heat exchangers area.
Occasional (seasonal) cleaning consists of regular weekly cleaning plus detailed cleaning of the heating
chamber from above.
How often do I need to clean the boiler? This depends on several factors, most important is the
quality and purity of the wood pellets used. Weekly cleaning has to be performed 1-2 per week, seasonal
cleaning 1-3 times during the heating season.
However if pellets of extremely bad quality are used, the cleaning frequency can change dramatically.
Boiler would not last long.
What tools do I need to clean the boiler? Simple cleaning set is delivered with the boiler. However,
ash-vacuum-cleaner would make things faster and easier.
Before performing any of the steps described below, boiler must be turned off and completely cold.
This is especially important for heat-exchanger cleaning. If they are still hot while bar is moved up and
down, they will be damaged.
It is obligatory to wear gloves for any operation described below.
