INSTRUCTIONS IN CASE OF EMERGENCY
The Ariterm bio-burner is a safe piece of equipment, if it is used correctly and serviced
according to the instructions.
Some possible emergencies are described here together with instructions for dealing with them.
Burn back
(fire has spread from the burner to the burner auger)
The burn back protectors react to a rise in temperature of the burner auger as follows:
1. The pulse-controlled burn back protector sprays water onto the fuel, increasing its
moisture content and the fire is doused before it has time to spread further. The unit does
not stop and does not emit an alarm. Protection can be extended with a non-return valve,
pressure tank and pressure warning gauge. FOR MORE INFORMATION SEE THE
AUTOMATION SYSTEM OPERATING INSTRUCTIONS!
2. The burn back thermostat emits an alarm for the burn back, the burner auger and hopper
are forced to empty. The combustion air fans are stopped and flue gas extractor continues
to function. The objective of the safety measures is to force the fire pocket back to the
burner and bring the equipment to a halt. The storage auger does not move and does not
transport new fuel to the burner auger.
3. The AVTA valve trips and fills the auger pipe and hopper with water. Protection can be
extended with a non-return valve, pressure tank and pressure warning gauge. Only for
wood chip systems!
If the fire has spread to the fuel storage, DO NOT open the storage door or hatch. CALL THE FIRE
BRIGADE! Open the storage sprinkler system valve slowly (if fitted).
