Commissioning the boiler
(User | Installer)
NOTE!
The controller settings are freely adjustable due to the variety of existing central heating
installations, heat demand of the building as well as fuel calorific value. The user sets the
boiler operation parameters himself. This activity is not subject to service.
SD DUO BIO boilers are equipped with one combustion chamber - the bottom one with an integrated furnace.
First commissioning of the boiler - checking the connections
Before the first start-up of the boiler check all the screw connections and tighten them if there is any play. If the
boiler was disassembled to bring it into the boiler room, remember to properly seal the boiler frame - burner
interface (high temperature silicone). The next step is to connect all electrical devices controlled by the boiler
(pumps, actuators, valves, etc.), and to connect temperature sensors in accordance with the installation
diagram.
NOTE!
Incorrect placement of the sensors may result in malfunction of the boiler.
TIP!
When all the above steps have been completed, you can proceed to the boiler
commissioning procedure.
