Connection and installation dimensions of the water heater [mm]

CONNECTION TO THE WATER SUPPLY

The water heater connections for the in-ﬂ owing and out-ﬂ owing water are colour-coded. The

connection for the supply of cold water is coloured blue, while the hot water outlet is coloured

red.

The water heater may be connected to the water supply in two ways. The closed-circuit

pressure system enables several points of use, while the open-circuit gravity system enables

a single point of use only. The mixer taps must also be purchased in accordance with the

selected installation mode.

The open-circuit gravity system requires the installation of a non-return valve in order to

prevent the water from draining out of the tank in the event of the water supply running dry or

being shut down. This installation mode requires the use of an instantaneous mixer tap. As

the heating of water expands its volume, this causes the tap to drip. The dripping cannot be

stopped by tightening it further; on the contrary, the tightening can only damage the tap.

The closed-circuit pressure system requires the use of pressure mixer taps. For safety

reasons the supply pipe must be ﬁ tted with a return safety valve or alternatively, a valve of

the safety class that prevents the pressure in the tank from exceeding the nominal pressure

by more than 0.1 MPa. The outlet opening on the relief valve must be equipped with an outlet

for atmospheric pressure.

The heating of water in the heater causes the pressure in the tank to increase to the level set

by the safety valve. As the water cannot return to the water supply system, this can result in

the dripping from the outlet of the safety valve. The drip can be piped to the drain by installing

a catching unit just below the safety valve. The drain installed below the safety valve outlet

must be piped down vertically and located in the environment that is free from the onset of

freezing conditions.

In case the existing plumbing does not enable you to pipe the dripping water from the return

safety valve into the drain, you can avoid the dripping by installing a 3-litre expansion tank

on the inlet water pipe of the boiler.

In order to provide correct operation of the relief valve, periodical inspections of the relief

valve must be carried out by the user. To check the valve, you should open the outlet of the

return safety valve by turning the handle or unscrewing the nut of the valve (depending on

the type of the valve). The valve is operating properly if the water comes out of the nozzle

when the outlet is open.
