tions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and
risk of danger.
3. Note that the appliance is exclu-
sively for use in the applications
detailed in these installation
instructions. Any other use will
not be considered to comply

malfunctions which may influ-
ence safety.
2. Functional description
The temperature relief valve is
actuated by the flow temperature
of the heat generator. It comprises
a spring-loaded valve and a
bellows operated temperature
sensor. When a boiler flow tempe-
rature of 95ºC is reached the force
exerted by the bellows system
becomes greater than the force of
the spring and the valve opens.
Heated potable water then flows
out and this is replaced by cold
water from the supply network.
This absorbs excess heat from the
heat generator and prevents over-
heating.
3. Application
Multi-fuel boilers with integral
water heating or condensing coils
in closed solid-fuel fired heating
systems to EN 12828.
