6.4 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 location is determined by your local code requirement.
It should remove all electrical power from the boiler.
Safety valve / Over Pressure Relief Valve
This valve opens when the pressure inside the heating system increases to max. 43.5 PSI.
For North America, a 30 PSI Relief Valve is supplied with each boiler. This valve must not be
locked out or plugged and must be within 3 feet of the boiler, with no valves between the
relief valve and boiler.
Low Water Detection
The "Low Water Detection" device is connected to the Emergency Stop of the boiler.
Should a low water condition be detected, the boiler stops firing immediately. This device
must be of the manual reset variety.
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 230° F, then the heating system switches off.
Expansion tank
All heating systems must be equipped with an expansion tank.
The overall size of the heating system volume will dictate the required expansion tank size.
