Activities related to controller operation should be performed according
to procedures included in the controller operating manual.
Depending on the weather conditions, burning intensity and the boiler heat
output should be adjusted accordingly, regulating a temperature of water leaving
the boiler (or, when the three- or four-way valve is installed, by changing settings
of the control shutter).
The controller simultaneously controls operation of pumps: central heating, do-
mestic hot water, and mixing (when the heating system is equipped with pumps).
It is not recommended to open any door during the boiler operation, as this
may cause flue gas return to the hopper. During firing smoke can penetrate into
the boiler room or retting (sweating) of the boiler. When the boiler and the flue pipe
are warmed these adverse effects should be reversed.
In the central heating system, the heat demand changes with changes in the
external conditions, i.e., time of the day and changes in the temperature outside.
The temperature of water leaving the boiler also depends on the building energy
performance, i.e., on construction materials, particularly insulation, used for its
construction.
MANUAL FIRING
When the furnace firing with the heating spiral fails (alarm status: "FAILURE OF
FIRING WITH HEATER"), the heating spiral may be damaged. In such situation
the following should be checked: 1° whether there is fuel in the hopper and the
gearbox is blocked by, e.g., undesirable object present in the tank, 2° whether the
furnace is not filled with excessive amounts of ash preventing fuel firing with the
heater. When it is found that the heating component is really damaged, start the
burner in the manual firing mode according to the following order:
1. The furnace must be cleaned of embers and soot, and the burner controller
must be switched off
2. Load fuel on the furnace grate in the manual mode
3. Pour firing fuel over fuel, wait until it is partly absorbed
4. Light it
5. Start the controller selecting the function "FIRING"
A person operating the boiler should be aware that
some boiler surfaces are hot,
and safety gloves must be worn before touching them!
