5.4 Safety systems
The following safety measures are the prerequisite for safe operation of your system.
Emergency stop switch
Every heating system must be able to be switched off with an Emergency Stop switch. The
Emergency Stop switch must be outside of the boiler room.
Safety valve
The hydraulic system must be equipped with a safety valve. This valve opens before the pressure
inside the heating system increases to max. 43 P.S.I.. The safety valve must be installed at the
highest point of the boiler, must not be locked and must be within 3.28 ft / 39.37 inch/ 1m of the boiler.
A 30 lb/sq in relief value is supplied with each boiler.
Safety temperature sensor
The pellet boiler is equipped with a safety temperature sensor. This is located on the pellet boiler. If
the boiler temperature exceeds 203°F then the heating system switches off.
Low water cut off
The hydraulic system must be equipped with a low water cut off. Falls the water level below a certain
level, the low water cut off switches off the heating system.
Starting up
Starting up for the first time has to be performed only by an
authorized service technician.
