e. Long boiler downtime and emergency stop.
In case of long downtime:
•
turn off the device, disconnect the boiler pump, the circulating pump
and the burner
•
disconnect the power supply
•
open the door slightly to air out the exchanger
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
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,
•
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
Leader in pellet boilers
9. Boiler operation and maintenance
Use the main switch on the control cabinet to deactivate the boiler and wait
until the boiler cools down - min. 1 hour before maintenance (boiler cleaning).
a. Burner operation guidelines:
Normal daily operation:
•
check the correct operation of system components: burner, control
system
•
check water pressure on a pressure gauge
•
check fuel level and quality and fuel feed system operation
•
check hydraulic joints leak tightness
•
keep the boiler room clean and tidy.
In case of any performance issues, remove the faulty devices or contact an
Authorised Service Centre to arrange a repair or an adjustment.
b. Inspection scope and schedule:
a) Monthly
•
check system water pressure
•
check safety valve operation
•
check control and safety device operation
•
check tightness of all connectors and joints
•
check balanced ventilation system
b) Minor inspection (every 6 months)
•
check rope seal and gaskets
•
• check boiler door thermal insulation
•
• check safety devices (safety valve, safety temperature limiter STB etc.)
•
• check flue gas (in case of a significant increase in flue gas temperature,
clean the combustion section of a boiler).
c) Major inspection (every 12 months)
•
check rope seal and gaskets
•
check boiler door and cleanout cover thermal insulation,
•
check safety devices (safety valve, safety temperature limiter STB etc.)
•
check flue gas
•
clean combustion section of the boiler
•
check thermal insulation of the boiler
•
check and adjust burner, adjust control system settings.
After long boiler downtime, the residual oxygen in boiler water and the oxygen
from the air mixed with carbonic acid have highly corrosive properties. Take any
precautions necessary if the boiler downtime is to exceed one week. Periodically
remove soot, sludge and ash from the combustion chamber, flue tubes and the
grate of Platinum Bio VG burner. Clean the boiler as required, at least every 2
weeks. Remove ash as required.
