Frequently Asked Questions - TG120NC6 GORENJE

How to install the Gorenje TG120NC6 water heater?

The installation must be carried out by a qualified technician. Fix the appliance vertically to the wall with screws of at least 8 mm diameter. Respect the minimum distances from the ceiling (dimension G = 260 mm) to facilitate anode inspection. The water heater must be installed in a room complying with standard IEC 60364-7-701 (bathroom). Before electrical connection, fill the tank with water.

Which water connection type to choose: closed or open?

The closed (pressure) system allows multiple draw-off points and requires a safety valve and a pressure reducer if the mains pressure exceeds 0.5 MPa. The open (non-pressure) system allows only one draw-off point and includes a check valve. The choice depends on your installation; for standard domestic use, the closed system is recommended.

How to connect the water heater to the electrical network?

Use a power cable with a minimum cross-section of 1.5 mm² (H05VV-F 3G 1.5 mm²). Connect the phase (L), neutral (N), and ground (PE) wires in the thermostat junction box. An all-pole disconnection device must be installed upstream. Always disconnect the appliance before any internal intervention.

What to do if water drips from the safety valve?

A slight drip is normal during heating due to pressure increase. If the flow is excessive, check that the valve is not obstructed. You can install a 3-liter expansion vessel to reduce dripping. Do not tighten the valve handle: this could damage it. If the problem persists, contact a professional.

How to adjust the water temperature?

The temperature is preset at the factory for optimal energy efficiency. To change it, disconnect the appliance, remove the cover, and turn the adjustment screw on the thermostat (range 20°C to 75°C). A lower temperature reduces consumption and scale. It is not recommended to modify this setting.

How to drain the water heater?

Disconnect the appliance from the electrical supply. Open the hot water tap on a mixer. Use the safety valve by operating its lever or unscrew the nut to drain through the water inlet hose. A small amount of residual water may flow when removing the flange. If there is a risk of freezing, completely empty the appliance.

What maintenance is required for the magnesium anode?

The anode must be inspected every 36 months by an authorized technician. If it is too worn, it must be replaced to guarantee the anti-corrosion warranty. The technician will record the inspection on the warranty sheet and can also descale the interior if necessary.

What to do if the water heater does not heat?

First check the power supply (circuit breaker, plug). Ensure the water hose is open and the tank is full. If the indicator light is off, the thermostat or heating element may be defective. Do not attempt to repair yourself; contact the authorized after-sales service.

Is it possible to install the water heater in a bathroom?

Yes, provided that standard IEC 60364-7-701 (VDE 0100 part 701) is respected. The appliance must be placed outside the safety volumes (zones 0, 1, 2). The installation must be carried out by a qualified electrician. Use a solid wall fixing.

What is the daily electrical consumption?

The energy consumption to maintain water at 65°C in an ambient temperature of 20°C is 2.60 kWh/24h according to standard EN 60379. Actual consumption varies depending on the set temperature, cold water inlet temperature, and frequency of draw-offs.

Connection and installation dimensions of the water heater [mm]

CONNECTION TO THE WATER SUPPLY

The water heater connections for the in-flowing and out-flowing water are color-coded. The connection for the supply of cold water is colored blue, while the hot water outlet is colored red.

The water heater may be connected to the water supply in two ways. The closed-circuit pressure system enables several points of use, while the open-circuit gravity system enables a single point of use only. The mixer taps must also be purchased in accordance with the selected installation mode.

The open-circuit gravity system requires the installation of a non-return valve in order to prevent the water from draining out of the tank in the event of the water supply running dry or being shut down. This installation mode requires the use of an instantaneous mixer tap. As the heating of water expands its volume, this causes the tap to drip. The dripping cannot be stopped by tightening it further; on the contrary, the tightening can only damage the tap.

The closed-circuit pressure system requires the use of pressure mixer taps. For safety reasons the supply pipe must be fitted with a return safety valve or alternatively, a valve of the safety class that prevents the pressure in the tank from exceeding the nominal pressure by more than 0.1MPa . The outlet opening on the relief valve must be equipped with an outlet for atmospheric pressure.

The heating of water in the heater causes the pressure in the tank to increase to the level set by the safety valve. As the water cannot return to the water supply system, this can result in the dripping from the outlet of the safety valve. The drip can be piped to the drain by installing a catching unit just below the safety valve. The drain installed below the safety valve outlet must be piped down vertically and located in the environment that is free from the onset of freezing conditions.

In case the existing plumbing does not enable you to pipe the dripping water from the return safety valve into the drain, you can avoid the dripping by installing a 3-litre expansion tank on the inlet water pipe of the boiler.

In order to provide correct operation of the relief valve, periodical inspections of the relief valve must be carried out by the user. To check the valve, you should open the outlet of the return safety valve by turning the handle or unscrewing the nut of the valve (depending on the type of the valve). The valve is operating properly if the water comes out of the nozzle when the outlet is open.

1 - Safety valve 6 - Checking fitting 2 - Test valve 7 - Funnel with outlet connection 3 - Non-return valve 4 - Pressure reduction valve H - Cold water 5 - Closing valve T - Hot water

Between the water heater and return safety valve no closing valve may be built-in because with it the function of return safety valve would be impeded.

The water heater may be connected to the water network in the house without reduction valve if the pressure in the network is lower than 0.5MPa (5 bar). If the pressure exceeds 0.5MPa (5 bar), a reduction valve must be installed. Prior to the electric connection the water heater must obligatorily be filled with water. By first filling the tap for the hot water upon the mixing tap must be opened. When the heater is filled with water, the water starts to run through the outlet pipe of the mixing tap.

CONNECTION OF THE WATER HEATER TO THE ELECTRIC NETWORK

Before connecting to the power supply network, install a power supply cord in the water heater, with a minimum diameter of 1.5 mm² (H05VV-F 3G 1.5 mm²). For this, the protection plate must be removed from the water heater.

The connection of the water heater to the electric network must be performed according to standards for electrical installation. Install a disconnect switch (separating all poles from the power supply network) between the water heater and the permanent power connection, in compliance with national regulations.

Electric installation

CAUTION: Prior to each access inside the water heater, it must absolutely be disconnected from the electric network!

USE AND MAINTENANCE

After connection to the water and electric network, the water heater is ready for use. The temperature of water in the appliance is automatically controlled by the thermostat, which is adjusted by the manufacturer. The adjustment can be modified by turning the adjustment screw on the thermostat inside the water heater. The adjustment range is between 20°C and 75°C. We do not recommend changing the manufacturer's adjustment, as this ensures the most economical consumption of electric energy and the smallest excretion of limestone. The operation of the electric immersion heater is shown by the pilot light. On the casing of the water heater, a bimetal thermometer is mounted, pointing clockwise (to the right) whenever there is hot water in the water heater.

When the heater is not used for a longer time, it must be disconnected from the electric network. At any risk of freezing of water in the water heater, the water must be emptied from it. Water is discharged from the heater via the inlet pipe. To this purpose, a special fitting (T-fitting) shall be mounted between the relief valve and the heater inlet pipe, or a discharge tap. The heater can be discharged directly through the relief valve, by rotating the handle or the rotating valve cap to the same position as for checking the operation. Before discharge, make sure the heater is disconnected from the power supply, and open the hot water on the connected mixer tap. After discharging through the inlet pipe, there is still some water left in the water heater. The remaining water will be discharged after removing the heating flange, through the heating flange opening.

The external parts of the water heater may be cleaned with a mild detergent solution. Do not use solvents or abrasives.

Regular preventive maintenance inspections ensure faultless performance and long life of your heater. The first of these inspections should be carried out by the authorized maintenance service provider about two years from installation in order to inspect the wear of the protective anticorrosion anode and remove the lime coating and sediment as required. The lime coating and sediment on the walls of the tank and on the heating element is a product of quality, quantity and temperature of water flowing through the water heater. The maintenance service provider shall also issue a condition report and recommend the approximate date of the next inspection.

Never try to repair any possible faults of the water heater by yourself, but inform about it the nearest authorized service workshop.

SWITCHING ON AND INSTALLATION DIMENSIONS OF THE BOILER [MM]

CONNECTION TO THE WATER SUPPLY

The inlet and outlet water connections are marked on the boiler pipes with corresponding colors. The inlet for cold water is in blue, and the outlet for hot water is in red.

You can connect the boiler to the water supply in two ways. Closed system, under pressure, allows connection of several outlets. Open system, without pressure, allows only one outlet. Depending on the chosen connection system, you must also equip it with the appropriate number of mixing taps. In the open system, without pressure, in front of the boiler a shut-off valve must be installed to prevent water from draining from the boiler if there is water in the water supply. In this connection method, you must use taps with aeration. When filling with water, the volume increases and it starts to drip from the pipe of the mixing tap. You cannot stop the dripping by tightening the tap handle, as this will only damage it. In the closed system, under pressure, on each outlet you must install a mixing tap. On the inlet pipe, for safety, a safety valve or group must be installed, which will limit the pressure in the heater so that it does not exceed 0.1 MPa above the allowed. The drain opening of the safety valve must have an outlet to atmospheric pressure.

When heating the water in the boiler, the pressure in the boiler rises to the degree set on the safety valve. Thus, the return of water back into the water supply is prevented, and it may start to drip from the drain opening of the safety valve. The dripping water can be drained through the drain hose, if you place it under the safety valve. The outlet pipe must be connected to the safety valve outlet, which is directed downwards, in a place that does not freeze.

The device allows the possibility of water entering the channel if the safety valve is turned. Instead of this, an expansion vessel with water can be installed above the heater.

For the correct operation of the safety valve, you must periodically check it. During the check, by turning the knob or pulling the ring (depending on the model), the safety valve should open. Water should flow from it, which means the valve works without error.

Legend:

1 - Protection cap 2 - Quality class 3 - Non-return valve 4 - Pressure relief valve 5 - Shut-off valve

6 - Test part 7 - Function

C - Cold water H - Hot water

Do not install a shut-off valve or safety valve, because then the operation of the safety valve becomes impossible.

You can connect the boiler to the water supply in the home without a pressure relief valve if the water pressure is below 0.5 MPa (5 bar). When the pressure is higher than 0.5 MPa (5 bar), a pressure reducing valve must be installed. Before connecting the boiler, you must fill it with water. At the first fill, open the hot water tap on the mixer. The boiler is full when water starts to flow strongly from the mixer pipe.

CONNECTION TO THE ELECTRICAL MAINS

Before connecting to the electrical mains, the boiler must be grounded with a wire with a cross-section of at least 1.5 mm² (H05VV-F 3G 1.5 mm²). The connection to the electrical mains must be made in accordance with the diagram and the applicable standards. Between the water heater and the fixed installation, a double-pole switch must be installed for simultaneous disconnection of both wires from the supply mains according to the installation instructions.

USE AND MAINTENANCE

Before switching on the boiler, it is ready for use. The temperature inside the boiler is controlled by the thermostat, which is set at the factory to the most economical position, guaranteeing minimal electricity consumption, minimal heat loss, minimal steam emission from the housing, and minimal operating costs. According to your wishes, the thermostat position can be changed by means of the screw that presses on the thermostat. The adjustment range is between 20-75°C. When you turn it fully to the left, you switch off the heating element. Adjustment of the factory setting is not recommended.

The control lamp indicates that the boiler is working. On the end cylindrical surface of the boiler, a bimetallic thermometer is pressed, which deflects in the direction of the clock hand when the boiler is filled with water.

If the device is to be used for a longer period of time, disconnect it from the electrical grid, but be aware that during this period it must be protected from freezing. The water from the boiler is drained through the drain valve of the boiler. For this purpose, it is recommended during installation between the safety valve and the drain to install a special fitting (tee) for the discharge valve. The water from the boiler can also be drained directly through the safety valve by turning the handle or the rotating cap of the valve in the position as during the pressure test. Before draining, the heating element must be disconnected from the electrical grid and the cold water inlet valve must be opened. After draining the water through the drain valve, a small amount of water remains in the boiler, which is removed when the boiler is tilted through the opening of the boiler jacket.

Clean the boiler surface with a mild detergent solution. Do not use abrasive or strong cleaning agents.

Through regular service inspections, trouble-free use and long life of the boiler are ensured. The inspection must be carried out by an authorized service at least once a year. During the inspection, the protective anode must be checked and replaced if necessary, and the water stone must be cleaned, taking into account the quality, quantity, and temperature of the water in the boiler. During the boiler inspection, depending on its condition, the service will recommend the following data for checking the condition.

In case of malfunction or damage to the boiler, do not repair it yourself, but contact your nearest authorized service.

C-Cold water H-Hot water

Changing the boiler and the safety valve must not be done without installing a shut-off valve for water, otherwise the safety valve would be rendered inoperative.

Before connecting the boiler to the water supply, install a pressure reducing valve if the pressure in the installation exceeds 0.5 MPa (5 bar). If the pressure exceeds 0.5 MPa (5 bar), it is mandatory to install a pressure reducing valve.

Before connecting the boiler to the electrical grid, it is mandatory to fill it with water. When filling for the first time, open the hot water tap. The boiler is full when water starts to flow from the tap.

CONNECTION TO THE ELECTRICAL GRID

Before connecting to the electrical grid, it is necessary to install a permanent connection cable with a cross-section of at least 1.5 mm² (H05VV-F 3G 1.5 mm²). To do this, remove the protective cover on the boiler. The connection of the boiler to the electrical grid must be done in accordance with the standards applicable to electrical installations. Between the boiler and the permanent installation, there must be a device for disconnecting all poles from the grid in accordance with local installation regulations.

Electrical connection diagram

WARNING: Before any intervention inside the boiler, it is mandatory to disconnect the boiler from the electrical grid!

USE AND MAINTENANCE

After connecting to the water supply and electrical grid, the boiler is ready for use. The water temperature in the boiler is automatically regulated by the built-in thermostat. The temperature can be adjusted by turning the thermostat knob in the center of the boiler. The adjustment range is from 20 to 75°C. We do not recommend that you change the factory-set temperature because it is the temperature at which electricity consumption is economical, and also scale formation is minimal.

The operation of the electric heating element is indicated by the control lamp. The boiler is equipped with a bimetallic thermometer, which moves in the direction of the clock hand when hot water is present in the boiler. If you do not intend to use the boiler for a long time, disconnect it from the electrical grid. If there is a risk that the water in the boiler will freeze, drain the water from the boiler. The water from the boiler is drained through the drain pipe of the boiler. In that case, it is recommended to install a safety valve on the drain pipe of the boiler, or a drain valve. The boiler can also be drained directly through the safety valve by pulling the ring, or by turning the valve cap to the position as during operation testing. Before draining the boiler, it is necessary to disconnect it from the electrical grid and then open the hot water tap on the connected faucet. After draining the water through the drain pipe, a small amount of water remains in the boiler, which is released when removing the heating flange (unscrewing the flange cover) through the opening of the heating flange.

Clean the boiler with a soft cloth and mild detergent. Do not use abrasive or aggressive cleaning agents.

The water heater must be serviced by an authorized service center at least once a year. The warranty is valid only if you have regularly performed the prescribed service procedures. Unauthorized modification of the prescribed service procedures is not allowed for 36 months. The service must be performed by an authorized service center, which will record the service on the warranty certificate. During the service, the condition of the anti-corrosion anode is checked, and if necessary, it is replaced with a new one, taking into account the quality, quantity, and temperature of the water in the heater. The service center will provide you with a schedule for the next inspection based on the data it has prepared.

Please do not attempt to repair any defects of the heater yourself, but instead notify the nearest service center.
