5 Safety installations
During the assembly attention must be paid to the safety installations. Only safety parts which are
tested and labelled for safety may be used. Before setting the boiler into operation make sure that
all safety installations are in place and belong to the state of the art and work. If necessary check
them again. Especially the pressure relief valve, the thermal safety relief valve and the expansion
vessel have to be checked before the boiler is allowed to start running. All safety installations have
to be checked by an expert every year.
Safety installations are not part of the purchased parts package.
safety relief switch:
The safety relief switch is connected to the pellet burner. If the temperature of the boiler rises
above 95°C the safety relief switch stops the burner. The burner will not start on its own if the boiler
temperature falls below 95°C. You have to reset the switch by hand. Check the water pressure, the
hydraulic system, especially every pump, the heating controller and the sensors before resetting the
safety switch (DIN EN 303-5 clause 3.21).
Please look at chapter 10, too!
thermal safety relief heat exchanger:
The Combiflame has a welded thermal safety relief heat exchanger.
The thermal safety relief heat exchanger may not be used as a domestic hot
water supply.
This heat exchanger has to be used with a thermal safety relief valve which is tested and labelled
for safety.
Thermal safety relief valve:
The thermal safety relief valve has to open at 95°C. The assembly of the thermal safety relief valve
has to be conform to EN 303-5 clause 4.1.5.11.3. The valve must be placed in the cold water supply.
It is not allowed to have any other valve in front of or behind the safety relief valve.
!
Make sure that there is always at least 2 bar water pressure in front of the
thermal safety relief valve. It is not allowed to have any other valve in front
or behind the safety relief valve! The drain of the thermal safety relief system
has to be visible. The cross-section of any tubing concerning to the thermal
safety relief system has to be at least 15 mm.
It is not allowed to set the Combiflame into operation without this safety system! The thermal safety
relief system has to be installed by an expert and checked every year.
Safety pressure relief valve:
The Combiflame has to be equipped with a pressure safety relief valve which is tested and labelled
for safety. The maximal system pressure is 3 bar. The drain of the pressure safety relief system has
to be visible.
