6. Boiler start-up, operation and stopping, including emergency stop
Start-up procedure:
• check system pressure
• open flue gas valve or throttle (if installed)
• check fuel level in the storage hopper (refill as required)
• check fuel condition and quality (fuel must not contain foreign material to
avoid damage to the boiler and its accessories)
• make sure the grate type in the burner is compatible with the fuel used
• connect the power supply, set boiler control system in service mode
• feed fuel from the storage hopper until it flows through the flexible duct
• press and hold the ON switch to activate the boiler control system - boiler
control system operates in automatic mode
•
• when starting from cold (also restarting after maintenance and cleaning)
close the heat transfer to the heating equipment to reach the dew point
faster (see boiler control system User Manual)
• at operating temperature connect the heating equipment in sequence
• visually check the system after a few days of operation (door and access
door, flue gas tightness)
• check boiler room ventilation
• check boiler room lighting (suitable for boiler operation and repair)
• check access to places which require periodical maintenance (cleanout,
control, storage hopper, and burner).
• check leak tightness of hydraulic connection between the boiler and the
central heating system
• check gas tightness between the boiler and the flue
•
• check if the electrical cables were not damaged in transit and if they are
properly connected to the device.
Installation restrictions
Do not start the boiler, if one of the following applies:
• no commissioning of the boiler by the relevant authorities is scheduled
(if required)
• incorrect boiler or fuel feed system operation
• flue ducts not vented
• no water in the boiler
• faulty safety valve operation
• flue ducts blocked
• boiler insulation damaged
• safety devices and gauges performance issues
• auxiliary equipment performance issues
• fire hazard near the boiler.

6.E Long boiler downtime and emergency stop
Long standstill:
• Press the main switch, disconnect the boiler pump, the circulating pump
and the burner.
• disconnect the power supply.
CAUTION! Freeze protection function is not working
with disconnected power supply.
• close all valves
• drain the boiler and the heating system via drain valve; open all cut-off,
control and vent valves to avoid freezing
• bottom door must be open to avoid condensation.
The emergency stop procedure is performed when the boiler condition or any
auxiliary device may cause boiler damage or hazard to the personnel.
CAUTION!
Rapid boiler cooling may increase the extent of damage.
Emergency stop may be caused by:
• no safety valve operation at exceeded allowable pressure,
• pressure section leakage,
• pressure section deformation,
• boiler room or auxiliary equipment explosion or fire,
• drain valve leakage,
• safety or control device failure,
• pressure gauge failure,
• circulating pump failure,
• flue gas explosion,
• pressure section fitting or welded joint leakage,
• drain pipe blockage,
• auxiliary equipment failure,
• other faults that cannot be removed during boiler operation due to safety
or technical reasons.
Emergency procedure:
• stop the boiler immediately (use the main power switch outside the boiler
room, if required)
• use suitable fire-fighting measures (extinguishers) in case of a fire.
