Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.
4.5. Fuel re
fi
lling
In order to ensure continuous boiler operation, the hopper must
be systematically re
fi
lled. In case of fuel shortage, the controller
shuts down the entire system and displays a fuel shortage warn-
ing. While re
fi
lling fuel, switch o
ff
the fan using the controller
button to prevent smoke back
fl
ow to the hopper.
CAUTION: During the loading, make sure that fuel is free
of impurities that might block the feeder (rubble, stones,
wood fragments or metal scrap).
4.6. Boiler stopping
Switch o
ff
the fan using the controller button, then scrape the heat to the ash pan using the hook supplied along with the boiler.
4.7. Cleaning and maintenance
Keeping the boiler clean is necessary for its reliable and faultless
operation. Even a thin layer of deposit impairs the recovery of
exhaust gas heat, which results in lower boiler e
ffi
ciency. Ac-
cumulated deposit may be the cause of damage to the device.
In order to prevent that, the boiler must be thoroughly cleaned
at least once in a week. After damping and cooling down of the
boiler, remove soot from the combustion chamber and the up-
per part of the heat exchanger using a wire brush and a scraper.
Remember also about the systematic cleaning of the air
chamber of the burner, the ash accumulated in it can block the
air supply to the burner, which hinders the correct burning of
fuel and causes excessive soot formation
