Caution
The installation diagram shows a pump station with an integrated non-return valve. This
type of pump unit may only be used with closed systems. In systems with drain-back,
installation of a pump unit with non-return valve is prohibited. There are special pump
units for these systems. Please contact the pump unit supplier for this.
Note
Use this installation diagram when you:
install the water connections (see section 7.4)
install the condensate drain
install the gas connection (see section 7.5)
fill the water heater
drain the water heater

7.4 Water connections
7.4.1 Unvented water connections
Warning
The installation should be carried out by a competent person, in compliance with general
and locally applicable regulations.
7.4.1.1 Cold water side
See (A) in the installation diagram.
Fit an approved stop valve (4) on the cold water side as required by the applicable
regulations.
The maximum working pressure of the water heater is 8 bar. Because the pressure
in the water pipe at times can exceed 8 bar, you must fit an approved pressure-
reducing valve (1).
Fit a non-return valve (5) and an expansion vessel (16).
Fit an expansion valve (15) and connect the overflow side to an open waste water
pipe.
7.4.1.2 Hot water side
See (B) in the installation diagram.
Note
Insulating long hot water pipes prevents unnecessary energy loss.
Optional: fit a temperature gauge (12) so you can check the temperature of the tap
water.
Fit the T&P valve (3).
Fit a stop valve (11) in the hot water outlet pipe for servicing.
7.4.1.3 Circulation pipe
See (C) in the installation diagram.
If an immediate flow of hot water is required at draw-off points, a circulation pump can be
installed. This improves comfort, and reduces water wastage.
Fit a circulation pump (6) of the correct capacity for the length and resistance of the
circulation system.
Fit a non-return valve (5) after the circulation pump to guarantee the direction of
circulation.
Fit two stop valves for servicing (4).
Connect the circulation pipe according to the installation diagram.
