PLEASE NOTE! We recommend that
water-powered extinguishing systems are
fitted with a 50-litre membrane expan-
sion tank (RST), non-return valve and
pressure warning gauge. This means that
a possible drop in supply pressure does
not jeopardise the operation of the safety
equipment.
c. Burn back thermostat
• The burn back thermostat sensor is installed in the burner auger pipe, under the visor
beside the AVTA sensor. In a burn back situation, the automated system extinguishes the
combustion air fans and stops all operations in the stoker. The fuel in the burner auger is
driven to the burner head. After this, the burner auger also stops. The automation system
maintains flue gas extractor operation. Adjustment range 60-70 °C.
d. Other safety systems
• A shut-off valve is fitted from the water supply system through which the user may draw
water manually into the feed auger and hopper.
• A fire alarm monitoring the fuel stoker temperature can be fitted as an option.
