When planning for the recovery rate as stated or calculated, allow for the corresponding circulation pump.
The stated recovery rate is only achieved when the rated output of the boiler is equal to or greater than that stated under "Recovery
rates". Please also refer to the corresponding sizing chart at the end of this manual.
*2
Measured values are based on a room temperature of 68 ºF / 20 ºC and a domestic hot water temperature of 149 ºF / 65 ºC and can
vary by ±5%.
*3
To overcome mechanical room access problems, the front panel with thermometer and side panels can be removed, the adjustable feet
unscrewed, and the Vitocell 300-H turned on its side.
*4
This is the net width of the Vitocell 300-H after removing the outer casing to ease problems of access into the mechanical room.
