4.1. Feed system –alarm status
In case of exceeding 60
°C
in the feed system, alarm is activated with blinking display „feeder
overheating”.
ATTENTION!
After alarm occured it is recommended to determine cause of alarm and remove it.
4.2. Feed system protection
Feed system is designed in such a way that flame from burner is not able to get to the pellet hopper. Safe
feeding is assured by system of two feeders jointed together with flexible, vertical chute. Fuel feeding is
continually monitored by boiler’s controller.
Proper feeders cooperation guarantees that vertical chute is always empty – it is a burn-back
protection.
