6. Boiler start-up, operation and stop 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 flexi-
ble duct
press the main switch to activate the boiler control system - Platinum
Bio 2 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 re-
pair)
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
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 standstill and emergency stop
Long standstill:
press the main switch, disconnect the boiler pump, the circulating
pump and the burner, and disconnect the power supply.
CAUTION!
A freeze protection function is not working
with disconnected power supply.
close all valves
drain the boiler and the heating system via a 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 which cannot be removed
during boiler operation due to safety or technical reasons.
Emergency procedures:
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
