Installation

2.1 

Wall mounting

Fit the 

EWH

 Comfort / Comfort N wall-mounted storage water heaters in a frost-proof room next to 

the connection point.
The materials used to mount the appliance must be selected according to the strength of the wall. 
The combined weight of the storage water heaters and their water illing (see the table „Technical 
speciications“) must be taken into consideration.
The position of the screws required for installation is shown in Figure 3.  
The mounting brackets for installation are an integral part of the storage water heater.
The water heaters are only suitable for vertical wall mounting. The water connections must point 
downwards. 

2.2 

Water connection

The appliance must be connected to the water system by an authorised specialist technician, 
taking the applicable installation instructions and the relevant standards and regulations into 
consideration. 
The water connection is unvented (pressure-proof ) to supply several drawing points.
The wall-mounted storage water heater is suitable for connection to plastic pipe systems.
Information on connecting to plastic pipe systems: In the event of malfunctions, temperatures of up 
to 95 °C (max. 0.6 MPa) can occur. Any plastic pipes used must be designed for these conditions.

If the water pressure is higher than 5 bar, a pressure reducer must be itted in the cold-water 
supply line.
Caution: The appliance is under pressure. During the heating process, expansion water will 
drip from the safety valve. If water continues to drip when heating is completed, please inform 
your contractor.

Before connecting the storage water heater to the water pipe, rinse out the pipe thoroughly to 
prevent any foreign objects from entering the storage water heater or the safety components.
It is recommended to install the storage water heater in the way shown in Figure 4.

The storage water heater must always be installed together with an approved diaphragm 
safety valve.

The safety information given in the installation instructions for the diaphragm safety valve must be 
observed. Regularly check the function of the safety valve.
The safety valve protects the storage water heater from excessive increases in pressure. The 
EWH Comfort wall-mounted storage water heaters are itted with a safety valve without non-return 
valve as an accessory. The EWH Comfort N wall-mounted storage water heaters are itted with a 
safety valve with non-return valve as an accessory. The safety valve must be actuated at regular 
intervals to prevent it from jamming as a result of furring (lime deposits).
The dripping-water outlet of the safety valve must always remain open to the atmosphere. 
The dripping-water outlet must be connected to a downward-pointing drain pipe which ensures 
unobstructed drainage of the water.
Filling: After connecting the storage water heater, open the stop valve.  
Then open the hot-water tap. The storage water heater is full when water is discharged from the 
hot-water tap.  
Then close the outlet tap and check the system for leaks.

Never connect the storage water heater to the electrical power supply without irst checking 
whether the storage water heater is actually illed with water.
