Installation Boiler transport Removing the casing Boiler transport The R40 boiler will be supplied as a complete unit being fully assembled and pre-tested. The packaging dimensi- on is 1050x572x575mm for boiler types 50-85 and 1185x674x665mm for boiler types 100-150, which makes it possible to transport all models through a normal door in one piece.
Installation Boiler installation Connecting the boiler Boiler installation The boiler should be positioned in a frost-proof boiler room. If the boiler room is on the roof, the boiler itself may never be the highest point of the instal- lation. When positioning the boiler, please note the recommended minimum clea- rance in the picture.
