Frequently Asked Questions - KGV200 GORENJE

How to install the KGV200 tank?

Install the device in a dry, frost-free location, preferably near heat sources (boiler room). Electrical and water connections must be carried out by a qualified installer. Before connecting, install the protective coating following the instructions in the manual.

What are the exact dimensions of the KGV200?

The dimensions are: height 1550 mm, width 740 mm, depth 560 mm. The outer diameter is approximately 650 mm.

What is the weight of the device empty and full?

Empty, the tank weighs 82 kg. Filled with water, the total weight reaches 282 kg.

What is the purpose of the built-in heat exchanger?

The heat exchanger heats the domestic water using various external energy sources: central heating boiler, solar panels, or heat pump. There is a lower heat exchanger (6.6 L, 1.05 m²) and, on some models, an additional upper heat exchanger.

How to install the safety valve?

The safety valve or safety group must be installed on the cold water supply pipe. It prevents overpressure exceeding 0.1 MPa above normal pressure. The discharge nozzle must be open to the atmosphere. Check its proper operation every 14 days by turning the handle or loosening the nut.

Can an electric heating element be added?

Yes, the tank can optionally receive an electric heating element type R (on Ø180 mm flange) or type SH (on G 6/4 sleeve). This provides backup heating when other sources are insufficient or unavailable.

How to maintain the device?

Clean the exterior with a mild detergent and a damp cloth. Do not use solvents or aggressive products. Drain if there is a risk of freezing. Have the anode checked and the interior descaled by a professional after 2 years, then according to after-sales service recommendations.

What to do if the safety valve drips?

If the valve drips during normal operation, it may be due to overpressure. You can install an expansion vessel on the supply line, with a volume of at least 3% of the tank volume (i.e., 6 L for the KGV200). This reduces unwanted water discharge.

How to drain the tank?

First open a hot water tap. Then open the drain valve located on the cold water supply pipe. Completely empty the water to prevent freezing or to perform maintenance.

What is the maximum allowable water pressure?

The maximum working pressure is 0.6 MPa (6 bar). If the mains pressure exceeds 0.5 MPa, a pressure reducer must be installed upstream to not exceed this value.

HE - Heat exchanger

On the rear side of the hot water tank there are special channels (H1, H2) for mounting the feelers for regulation of the system connection of the hot water tank to other heating sources. Access to the channels is under the covering joint of the protective covering, approximately in the middle of the tank height.

Insert the feeler into the channel and fix it with the enclosed rubber tap. Recommended position (h1, h2) of the feeler is marked on the drawing:

• If the feeler is mounted higher than recommended, the thermostat will react too fast, the operating time of the circular pump will be shorter and the difference between the temperature in the hot water tank and heating media after the thermostat switch off will be higher. This means that the quantity of water in the hot water tank and its temperature will be lower,
• If the feeler is mounted lower than recommended, the operating time of the circular pump will be longer and the difference between the temperature in the hot water tank and heating media after the thermostat switch off will be lower. This means that the quantity of water in the hot water tank and its temperature will be little higher.

CONNECTION TO THE WATER SUPPLY

Before connecting the hot water tank, install the protective covering. Take off the top cover and insert the covering, make sure the slots on the covering match the connections on the hot water tank. Zip the zipper from top to bottom and tighten the tapes on the top edge of the covering. Replace the top cover. Insert the thermometer into the prefabricated sleeve on the front of the hot water tank; make sure to cut the opening for the sleeve into the covering. The connection to water supply network and fastening of the coloured rosettes shall be made according to the markings defined in previous Section.

For safety reasons the supply pipe must be fitted with a return safety valve that prevents the pressure in the tank from exceeding nominal pressure by more than 0.1 MPa. 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 dripping from the outflow of the safety valve. The drip can be piped into the drain by installing a catching unit just below the safety valve. The drainpipe fitted under the safety valve outflow must be piped down in a straight vertical line and located in an environment 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 expansion tank on the inlet water pipe of the boiler. The volume of the expansion vessel shall be at least 3% of the volume of the hot water tank.

The water heater may be connected to the household water supply system without a pressure-reducing valve provided the supply mains pressure is less than 0.5 MPa.

In case of the mains pressure exceeding 0.5 MPa, a pressure-reducing valve must be installed to ensure that the pressure on the supply side of the heater does not rise above the nominal value.

CONNECTION TO ALTERNATIVE SOURCES OF HEATING

The heaters enable the water for sanitary use to be heated by alternative sources of energy (e.g. central heating, solar power, ...) by installing one or two heat exchangers.

Additionally, a heating pump may also be fitted to the side flange of the tank.

Options for connecting the water heater to various sources of heating are shown in the drawings below.

Connection to solar panels and central heating hot-water system

The water heater is ready for use once it has been connected to water and other sources of heating.

The usual main sources of heating of water for sanitary use are central heating or solar power; in this case any regulation of water heating is performed in the heating system.

• If you need higher temperature of water than assured by other heating sources,
• If due to seasonal or other conditions there are no main heating sources.

In case of exposure to sub-zero temperatures, the water should be thoroughly drained from the heater before the onset of freezing conditions.

Once that is done, open the hot water tap on one of the mixer taps connected to the water heater. The water from the water heater drains by way of the drain valve on the inlet pipe.

External parts of the water heater may be cleaned with a mild detergent solution. Do not use solvents and abrasive cleaners.

Regular preventive maintenance inspections ensure faultless performance and long life of your heater. The first of these inspections should be carried out by an authorised maintenance service provider about two years from the date of installation in order to inspect the wear of the corrosion protection anode and to remove any limestone as required. Build-up of limestone is a product of quality, quantity and temperature of water flowing through the water heater. While inspecting the heater, the maintenance service provider will also recommend the date of the next inspection.

Wear of the corrosion protection anode is carried out visually. Replacement is required when the inspection reveals that the anode diameter has been substantially reduced or worn all the way to the steel core.

Tank warranty is subject to regular inspections of the protective anode.

In the event of the water heater breaking downa you are kindly requested to contact the authorised maintenance service provider located closest to you! Please do not attempt to repair the unit yourself
