PER-EKO type KSW & KSW PLUS – Instruction Manual
Diagram depicting boiler installation with a cross valve and a central heating tank.
4.3 Supplementation of the boiler with central heating water
Water supplementation can be performed from the water supply system via the release tap in the boiler by means
of elastic hosepipe which is to be detached from the boiler once the installation is filled with water and the release
tap is closed. Boilers type KSW PLUS are adapted to operate together with the circulation pump.
4.3.1 Information on terms and conditions enclosed in the PN-91/B-02413 norm

The boiler ought to be connected with the installation by means of appropriate connectors.

The heated water coming from the heating system cannot be used for other purposes than heating only and
the working pressure cannot be higher than the acceptable pressure for the application with installation
elements and devices.

The inner diameter of the safety pipe ought to be at least 25mm.

The inner diameter of the expansion pipe ought to be at least 25mm.

The safety pipe and the expansion pipes (with the exception of vertical sections) ought to be run without
bends, with a decrease of at least 1% towards the boiler; changes in directions of pipes ought to be carried
out using arcs with the axis radius of at least 2d, where “d” stands for the external pipe diameter.

The inner diameter of the overflow pipe should not be smaller than the inner diameter of the safety and the

The inner diameter of the venting and the signaling pipe ought to be at least 15mm.
5. BOILER OPERATION MANUAL
5.1 Water filling
Before lighting the boiler up, the system and the boiler are to be filled with water, according to the instructions
given by the executor of the system. The hardness of water should not exceed 20˚n. Check whether the expansion vessel
(located in the highest point in the system) has water inside it. This inspection is to be carried out during a period of few
seconds, in order to ensure that the water flows down the vessel.
