INSTALLING THE TEMPERATURE LIMIT VALVE
The Pressure Vessel Directive requires that a manually-filled wood-burning boiler must be
equipped with a safety device, which prevents the boiler from overheating if circulation in the
accumulation tanks is prevented for some reason. The Ariterm 35+ boiler includes a cooling
spiral. We recommend the SYR 3065 temperature limit valve for this boiler. This does not, ho-
wever, replace other safety devices such as a safety vent.
Installation
The temperature limit valve is connected to the cooling spiral or to the fork-junction in the
warm process water pipe so that when the valve operates, it sends hot water down the drain.
The temperature sensor is installed on the sleeve on the upper part of the boiler, using a DN 20
x 150 well.
