5 Installation

4.4

Requirements for the installation site

▶
Select the installation site so that the pipes can be easily
routed (gas supply, water supply and drain).
▶
Do not install the product above an appliance whose use
may damage the gas-fired instantaneous water heater
(e.g. above a cooker that can emit grease vapours).

Wall-mounting the product

Conditions: The load-bearing capacity of the wall is sufficient, The fixing
material may be used for the wall
▶
Wall-mount the product as described below.
Conditions: The load-bearing capacity of the wall is not sufficient
▶
Ensure that wall-mounting apparatus on-site has a suf-
ficient load-bearing capacity. Use individual stands or
primary walling, for example.
▶
Do not wall-mount the product if you cannot provide
wall-mounting apparatus with a sufficient load-bearing
capacity.
Conditions: The fixing material may not be used for the wall
▶
Wall-mount the product as described as follows using
the permitted fixing material provided on-site.
1. Drill the holes for the fixing screws while taking into
consideration the dimensions.

3. Use suitable fixing material to install the back wall of the
unit to the wall.
5 Installation
Danger!
Risk of scalding and/or damage due to
incorrect installation leading to escaping
water.
Stresses in supply lines can cause leaks.
▶
Install the supply lines without tension.
▶
If you use plastic supply lines for the hot-
and cold-water connection, these must
withstand temperatures up to 95 °C and
pressures up to 1.0 MPa (10 bar).
Caution.
Risk of material damage due to the gas
leak-tightness test.
At a test pressure of >11 kPa (110 mbar), gas
leak-tightness tests may cause damage to
the gas valve.
▶
If, during gas leak-tightness tests, you
also place the gas lines and the gas valve
in the product under pressure, use a max.
test pressure of 11 kPa (110 mbar).
▶
If you cannot limit the test pressure to
11 kPa (110 mbar), close any gas isolator
cocks that are installed upstream from the
product before you carry out the gas leak-
tightness test.
▶
If, during gas leak-tightness tests, you
have closed the gas isolator cock that is
installed upstream of the product, relieve
the gas line pressure before you open this
gas isolator cock.

Integration into a solar system

The inlet temperature must not exceed 45 °C.
The hot water temperature must not exceed 60 °C.
▶
Install thermostatic 3-way valves.
