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.
2.
To secure the product, depending on the installation
site, use wall anchors, hooks, bolts or threaded bolts as
the fixing material.
3.
Use suitable fixing material to install the back wall of the
unit to the wall.

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.
5.1
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.
