1.16 Safety sprinkler device
Valve type SYR (fixed setting) safety sprinkler device.
The safety sprinkler device is fitted and adjusted by the factory and the heating and ventilation fitter will
have fitted this to thr domestic water suply. If the temperature on the outside of the worm conveyor pipe
exceeds 95°C, the valve vil be activated and water will be allowed to enter.
Water connection must take place via a tank with a float needle valve (an elevated tank) with a capacity
of 20 liters, and a connection to the water supply. Corresponding function can be achieved with an
pressurized tank set for water sprinkling. (Refer to sketch below).
After extinguishing, if necessary, with water, the combustion chamber must be dried out:
Remove the water and empty the air chamber by dismounting the "drain screw" (pos. 8a - fig. 1.1,
situated behind the lowest front plate). REMEMBER to mount the "drain screw" again.
Remove wet fuel, if any, from the worm conveyor/auger and hopper before this can expand and
thus block the worm conveyor/auger.
Before starting up the boiler, examine why the backfire safety sprinkler has been activated.
