*1 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 68ºF (20ºC) and a domestic hot water temperature of
149ºF (65ºC) 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.
*5 Only for 92 and 119 USG (350 and 450 L) saturated steam 15 psig at 250°F (121°C)
