2.2.7.1
Overheat safety valve
The stove must have a suitable overheat safety valve installed.
Before the system is commissioned it should be checked for leaks
and to ensure that it is functioning correctly.
A water pressure of at least 2 bar and a minimum throughput of
900 l / h must be provided at the cold water inlet of the overheat
safety valve. This supply line must not be capable of being shut off
and it must maintain a constant water pressure.
The installation of the overheat safety valve must be designed in
such a way that it is possible to check its functionality at any time.
Before connecting the cold water pipe to the stove, the pipe must be flushed to prevent the
introduction of impurities into the opening and closing mechanism of the overheat safety device.
2.2.7.2 Load Valve
The stove must be installed with a load valve to ensure that the return temperature is always
above 55°. The circulation pump should be controlled by a flue thermostat. This will inhibit the
formation of tar on the boiler and so extend cleaning intervals as well as protecting the boiler
against condensation.
2.2.7.3 Integration into the heating system
The boiler stove should only be integrated into a heating system after the complete system has
been designed by an appropriately qualified and experienced heating engineer.
All the relevant safety standards must be complied with.
The intended heating system can be laid out as an open or closed heating system. In any case
sufficient overheating safeguards must be installed.
If installed on a closed (pressurised) system, a pressure relief valve should be installed in the water
circuit as close as practicable to the appliance and in a position where it would vent safely, along
with an overheat safety valve (see section 2.2.7.1).
If installed on an open vented system, the feed and expansion tank must be manufactured to BS
4215, and be designed to withstand the 500-hour boil test without leaking or collapsing. It should
be installed as high as possible, in the highest part of the circuit and as near as possible to the
boiler.
A means of dissipating heat, e.g. a radiator fed by gravity, should be provided so that heat can be
dissipated in cases where the pump fails or is not switched on and the appliance continues to
produce heat.
The water in the central heating system should contain suitable antifreeze to give frost protection.
After a period of inactivity, on no account should the appliance be lit until it is ensured that there
is a free flow of water through the central heating and hot water systems. The use of a return-
flow-elevation/load unit (such as an LK 810 ThermoMat Eco load unit) with an adjusted minimum
