IV. DESCRIPTION AND PRINCIPLE OF WORK

The appliance consists of a boiler shell, a ange at its lower end /with

vertically-installed boilers/ or lateral ange/with horizontally-installed

boilers/, protective plastic panel and non-return safety valve.

1. The body consists of a steel reservoir (water tank) and housing (outer

shell) with thermal insulation placed in-between made of ecologically clean

high density polyurethane foam, and two pipes with thread G (table 1 to

g. 1a; table 2 to g. 1b) for cold water supply (marked by a blue ring) and

hot water outlet pipe (marked by a red ring).

The inner tank may be of two types depending on the model:

•

Made of steel protected form corrosion by a special glass-ceramics

coating

•

Made of stainless steel

The vertical water heaters may be outtted with a built in heat exchange

unit (boiler tube). The boiler tube’s entrance and exit are located at the

sides and represent pipes with thread G ¾ “.

2. The ange is outtted with: electric heater and thermostat. The water

heaters with glass-ceramics coating are outtted with a magnesium

protector.

The electric heater is used for heating the water in the tank and is

managed by the thermostat, which automatically maintains the set

temperature.

The thermostat has a built in overheating safety device, which switches

of power to the heater when the water temperature reaches excessive

values.

3. The safety-return valve prevents the appliance’s complete emptying

in the event the cold water supply is interrupted. The valve protects the

appliance from pressure increases higher than the allowed value during

heating (! pressure increases upon an increase of temperature), via

release of excess pressure during the drainage opening

Attention! The safety-return valve cannot protect the appliance in the

event of water mains pressure in excess of the acceptable pressure

stated for the appliance.

V. MOUNTING AND SWITCHING ON

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

ooding, explosion and/or re.

Installation, connection to the main water and power supply, and putting

into operation must be carried out by certied electricians and technical

personnel certied 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.

1. Mounting

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 (g. 1a, table 1) – When installing the appliance onto a wall

– the boiler should be hanged through the upper carrying plate which is xed to the

appliance shell.

Two hooks are used for suspending the appliance (min. Ø 10 mm) set rmly 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 - g.1a.

•

Vertical installation

models with a diameter of 560 mm

(g. 1b, table 2)

When installing the water heaters models with a diameter of 560 mm follow the

installation instructions in g. 1b.

It is obligatory that the appliance is hanged through the two carrying plates which are

xed 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 (g.1c, 1d) – At

horizontal installation the distances between the carrying hooks are di󰀨erent

with the di󰀨erent capacities and these values are indicated in table 3 - g.1c

and table 4 - g. 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 outtted with oor 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 outtted with oor 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.

2. Water heater connection to the pipe network

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/ a󰀩xed 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 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 o. 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

lling of the water heater with water. After the lling is complete, a constant

stream of water must begin to ow from the water-mixing faucet. Now you

can close the hot water stopcock.

In the event you must empty the water heater, rst you must cut o󰀨 its

power supply. The inow of water from the water mains must rst be

terminated and the hot water tap of the mixing-faucet must be opened.

The water tap 7 (g 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, 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 ange, 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.

3. Water heater connection to the electrical network.

Attention! Make sure the appliance is full of water prior to switching on

the electrical mains power.

3.1. Models with power cord with a plug are connected by inserting the

plug into a contact. They are switched o󰀨 the power supply by drawing the

plug out of the contact.

Attention! The wall-plug must be properly connected to a separate

electrical circle that is provided with a protector. It must be earthed.

Water heaters tted with a supply cord without a plug.

The appliance has to be connected to a separate electricity circuit of the

stationary electrical wiring.The connecting has to be constant- with no plug

contacts. The circuit has to be supplied with a safety fuse (16A) and with

inbuilt device to ensure disconnection of all pole pieces in the conditions of

over-voltage from category III.

The connecting of the conductors of the supply cord of the appliance has to

be carried out as follows:

•

conductor with brown insulation – to the phase conductor of the

electrical wiring (L)
