Viessmann KOB PYROMAT DYN 45 Instructions For Assembly And Installation page 13

a) Safety equipment provided by the installing heating engineer
SV... Safety valve, pressure set max. 3.0 bar, homologated component as per DIN 3440
Nominal width of the valve for the connecting line and the exhaust pipe as per DIN 4751, Part 2
TS... Thermal run-off safety valve R ¾", homologated component, opening temperature 95-100°C,
(safety heat exchanger built into the burner)
KW... Cold water inlet DN 15 R ½", metal, fixed pipework, min. 2.5 bar, max. 3.5 bar
TSL... Drain pipe, thermal run-off safety valve R ¾", (NW 20)
EL... Air separator (recommended: absorption-type degasser)
ExG... Expansion tank closed, homologated
(Recommendation: connect on cool return flow, connected to the boiler via the forward flow without any
blockage units)
DAZ... Pressure gauge (manometer)
TAZ... Temperature indicator (thermometer)
b) Burner circuit with hydraulically switched heat storage tank
Boiler Burner circuit pump M20
KPM-DYN Make: Wilo model

1) Connecting thread for inlet
2) Length of the exhaust pipe up to 4.0 m (for longer lines, see DIN 4751 Part 2)
c) Designation of the motors, sensors and safety switches
Motors:
M1 Exhaust blower
M2 Feed auger
M11 Drive for cleaning/de-ashing
M12 Motor-operated air vent
M13 Motor-operated air vent
M16 Ignition device
M20 Burner circuit pump
Y20 Burner control valve
Safety switches:
N21.1 Temperature-limiting safety switch
S2 Safety limit switch
Maintenance lid for feed auger
d) Recommended design for accumulator,
The hydraulically switched heat storage tank has the following advantages:
Gentle control in automatic operation (increased efficiency, minimal emissions in practical operation)
-
- Higher performance peaks are possible for the consumers
Log operation is possible (see Operating Instructions)
-
