System components

The shunt valve
The shunt valve controls the heat supply from the boiler to the radiator circuit.
The room temperature can be adjusted on a scale on the thermostat. An automatic system
will significantly reduce fuel usage and provide a more comfortable environment.
The valve combination
The mixing valve is used to ensure that the temperature of the hot water in your shower
and elsewhere in the house is comfortable. Set the system to the temperature you want by
turning the thermostat between +/-.

Overheating protection

The overheating protection is a safety device if the burners thermostat should malfunction.
If the boiler has been overheated you must reset the overheating protection manually, by
pressing the red button (press hard) on the control panel.

Micro switch

The micro switch stops the auger alt. the whole burner, (depending on installed burner) if the
ash door is open. It´s important that this functions works and is checked regurlarly.
The sealings
The seals on the hatches must be checked every year. If the hatches do not seal properly,
the efficiency and the combustion process of the boiler will deteriorate.
Control panel
The functions of the control panel should be checked every year to avoid downtime of the
boiler or burner.

Cleaning

Cleaning is done from the top of the boiler. Take away the top cover and unscrew the nuts
on the lid over the tubes. Remove the turbulators and clean the tubes with the cleaning
handle with brush. Then open the ash compartment door and clean the burner and the ash
compartment. If your boiler is equipped with automatic cleaning of tubes, read the
instructions on pg. 11.

Flue gas temperature

The temperature that leaves the boiler should be in the range of 160-230°C if there is
condensation in the chimney the temperature must be higher.
To achieve a higher flue gas temperature you can cut the turbulators 5cm.
