a) Note:
- To reliably prevent boiler corrosion caused by condensation of exhaust gases, the boiler return flow temperature
must not under any circumstances be below 65°C. A boiler circuit pump with a modulating valve should be provided
according to the diagram for this purpose. The boiler circuit should be designed such that the temperature
difference between the forward flow and the return flow is equal to or less than 15°C.
b) Safety-relevant equipment included in the scope of performance provided by the installing
heating engineer
M 20 Boiler pump
Y 20 Boiler mixer
TS131 Thermal run-off safety valve R ¾”, homologated component; special-purpose design for opening
temperature 100°C, (safety heat exchanger built into boiler), from Pyrtec-720 2 safety heat exchangers in
parallel are required as well as 2 thermal run-off safety valves. These are not required for open systems,
but we advise installing these.
KW Cold water inlet, min. 2.5 bar, max. 3.5 bar
WMS Water level control device, homologated component; required in Germany starting from systems over 350
kW,Installation recommendation: WMS with magnetic transmission of the float movement to a switch unit
EL Air separator (recommendation: absorbition-type degasser)
ExO Expansion tank open, at the highest point in the system, heat insulated; for heating system
ExS Expansion tank closed; with design certification; for safety heat exchanger, max. 4.0 litres, 10 bar
DAZ Pressure indication device (pressure gauge)
TAZ Temperature indication device (thermometer)
c) Boiler circuit with open expansion, accumulator circuit if necessary, design recommendation
