Information on width without casing (350 and 500 litres)
350 litre: Where access into the boiler room is difficult, the front panel
with thermometer and the side panels can be removed, the
adjustable feet can be unscrewed and the DHW cylinder can
be turned to one side.
500 litre: Where access to the boiler room is difficult, removal of the
casing leaves the DHW cylinder with only the dimensions
given in the table.
Information regarding continuous output
When designing the system for the continuous output as stated or cal-
culated, allow for the corresponding circulation pump. The stated con-
tinuous output is only achieved when the rated boiler output
≥
contin-
uous output.
