Output based on 140ºF / 60ºC, 120 ºF / 49ºC system supply/return temperature.
*2
Net I=B=R rating based on piping and pick-up allowance of 1.15.
*3
If the gas supply pressure exceeds the maximum gas supply pressure value, a separate gas pressure regulator must be installed upstream of the
heating system.
*4
With pump rotational speed set to 100% flow capacity (2700 rpm), see Coding Address 045 in the Vitodens 200 Start-up/Service Instructions.
Pump factory default setting is 65% flow capacity (2000 rpm).
