MOUNTING AND SWITCHING ON
EN
Attention! Improper installation and connection of the
appliance may make it hazardous for the health and life of
consumers. It may cause grievous and permanent
consequences, including but not limited to physical injuries and/or
death. Improper installation and connection of the appliance may
also lead to damage to the consumers' property /damage and/ or
destruction/, or to that of third persons, as a result of, but not
limited to flooding, explosion and/or fire.
Installation, connection to the main water and power supply, and
putting into operation must be carried out by certified electricians
and technical personnel certified in installation of this category of
appliances, who have obtained their license in the state where the
installation and commissioning of the appliance are carried out, and in
compliance with its local legislation.
Mounting
1.
We recommend the mounting of the device at close proximity to
locations where hot water is used, in order to reduce heat losses
during transportation. In the event the device is mounted in a
bathroom, the selected location must exclude the possibility of
water spray contact from the showerhead or portable showerhead
•
attachment. Two methods of installation are possible:
Vertical installation (fig. 1a, table 1) – When installing the
appliance onto a wall – the boiler should be hanged through the
upper carrying plate which is fixed to the appliance shell.
Two hooks are used for suspending the appliance (min. Ø 10
mm) set firmly in the wall (not included in the mounting set).
The mounting bracket's construction designed for water heaters
intended for vertical mounting is universal and allows a distance
•
between the hooks of 220 to 310 mm - fig.1a.
Vertical installation (fig. 1b, table 2)
When installing the water heaters models with a diameter of 560
mm follow the installation instructions in fig. 1b.
It is obligatory that the appliance is hanged through the two
carrying plates which are fixed to its shell.
Attention! It is forbidden to install the appliance (models
with a diameter of 560 mm) with hooks.
•
Horizontal installation GCVH and GCH models (fig.1c, 1d) – At
horizontal installation the distances between the carrying hooks are
different with the different capacities and these values are indicated
in table 3 - fig.1c and table 4 - fig. 1d.
Warning! The appliance must be installed in such a
way, so as the protective plastic panel and the inlet/
outlet pipes to remain on the left side of the boiler (frontal
view). The cold water supply pipe (with a blue ring) must be
beneath the hot water discharge pipe (with a red ring).
Attention! In order to prevent injury to user and third
persons in the event of faults in the system for
providing hot water, the appliance must be mounted in
premises outfitted with floor hydro insulation and plumbing
drainage. Don't place objects, which are not waterproof under
the appliance under any circumstances. In the event of
mounting the appliance in premises not outfitted with floor
hydro insulation, a protective tub with a plumbing drainage
must be placed under the appliance.
Notice: the set does not include a protective tub and the user
must select the same.
Water heater connection to the pipe network
2.
Fig. 4: a) - for vertical installation; b) - for horizontal installation
GCVH; c) - for horizontal installation GCH;
Where: 1 - Inlet pipe; 2 - Safety valve; 3 - reducing valve (for water
main pressure > 0,6 MPa); 4 - Stop valve; 5 - Funnel connected to
the sewer network; 6 – Hose; 7 - Drain water tap.
Upon connecting the water heater to the water mains you must
consider the indicative color markings /rings/ affixed to the pipes:
blue for cold /incoming/ water, red for hot /outgoing/ water.
The mounting of the safety return-valve supplied with the
water heater is obligatory. The safety return-valve must be

Instructions for use and maintenance
mounted on the cold water supply pipe, in observance of the
direction arrow stamped on its body, indicating the incoming
water's direction. Additional stopcocks must not be mounted
between the safety return-valve and the water heater.
Exception: If the local regulations (norms) require the usage of
another protection valve or mechanism (in accordance with
EN 1487 or EN 1489), then it must be bought additionally. For
mechanisms operating in accordance with EN 1487 the announced
operational pressure must be no more than 0.7 MPa. For other
protection valves, the pressure at which they are calibrated must be
0.1 MPa lower than the one marked on the appliance's sign. In these
cases the safety valve which the appliance is supplied with should
not be used.
Attention! The presence of other /old/ safety
return-valves may lead to a breakdown of your
appliance and they must be removed.
Attention! Other type of stopping armature is not
allowed between the protection return valve (the
protective device) and the appliance.
Attention! The attaching of the safety return-valve to
pipes with threads G ½ '' longer than 10 mm is not
allowed, otherwise this may damage the valve and poses
danger for your appliance.
Attention! With boilers for vertical assembly, the safety
valve has to be connected to the ingoing pipe with the
safety plastic panel of the appliance being taken off. After it
has been assembled it should be in position as shown on Fig. 2.
Attention! The safety valve and the pipe between the
valve and the water heater must be protected from
freezing. During hose draining - its free end must be always
open to the atmosphere (not to be immersed). Make sure that
the hose is also protected from freezing.
Opening the cold-water stopcock of the water supply piping
network and opening the hot-water stopcock of the water-mixing
faucet carries out the filling of the water heater with water. After
the filling is complete, a constant stream of water must begin to
flow from the water-mixing faucet. Now you can close the hot
water stopcock.
In the event you must empty the water heater, first you must cut
off its power supply. The inflow of water from the water mains
must first be terminated and the hot water tap of the mixing-
faucet must be opened. The water tap 7 (fig 4a and 4 b) must be
opened to drain the water from water tank. If there is no such tap
•
build in the pipe line, than the water can be drain as follow:
Models equipped with safety valve with lever - You can drain
the water from the water heater by lifting the safety return-valve's
lever. Water will drain from the safety return-valve's drainage
•
opening
Models equipped with safety valve without lever - water can
be drain directly from inlet pipe of water tank after when you
disconnect it from water main
In the event of removing the flange, the discharge of several liters
of water, which remain in the water tank, is normal.
Attention! Measures must be undertaken to prevent
damage from discharging water during draining.
In case that the pressure in the water mains is over the value
pointed out in the above paragraph I, then it is necessary to
assemble a pressure reduce valve, otherwise the water heater
would not function properly. The Manufacturer does not assume
any liability for problems arising out of the appliance's improper
use.

Water heater connection to the electrical network.
Attention! Make sure the appliance is full of water prior
to switching on the electrical mains power.
