USER MANUAL

Sociable remark

When using this gas water heater, the following information’s must be

followed:

DISPOSAL:

Do not dispose this product as unsorted municipal waste. Collection of such waste

separately for special treatment is necessary.

It is prohibited to dispose of this appliance in domestic household waste.

For disposal, there are several possibilities:

• The municipality has established collection systems, where electronic waste

can be disposed of at least free of charge to the user.

INSTALLATION INSTRUCTIONS

Installation method

1. Installation of main body

Drill holes in the wall according to the dimensions of the gas water heater and fix

the M6 expansion bolts. Hang up the hanging bracket slot of the gas water heater

on the expansion bolt. Fix the gas water heater by screwing the nuts. Fix the

lower hanging brackets with two plastic expansion bolts.

2. Installation of water pipes

• The size of cold and hot water connector is G1/2.

• Before connecting up the appliance it is necessary to thoroughly flush and

purge the water and gas pipes in order to remove filings or other waste from

them.

• For the convenience of maintenance please install the water inlet valve near

the appliance.

• Connect the cold water and hot water pipes in correct order. Markings are

located on the bottom of the gas water heater near the connectors.

• Purge air from water pipes by opening all the taps, hot and cold. Then turn off

the taps and check for water tightness.

Important!!

The maximum inlet water pressure must be limited to 10 bar. If the water

supply is more than 10 bar or subject to pressure fluctuations above 10

bar, a pressure limiting valve must be installed to limit the pressure to 10

bar maximum.

Minimum water pressure is 0,2 bar.

Warning!!

Water with a temperature higher than 50°C can cause serious burns.

Always verify water temperature before use.

3. Installation of gas pipe

• The size gas connector is G1/2 or G3/4, depends on the model.

• The pipeline system should reach minimum rated gas pressure value for

the heater to perform the rated thermal load.

• Before connecting up the appliance it is necessary to thoroughly flush and

purge the water and gas pipes in order to remove filings or other waste

from them.

• Connect the gas transferring pipe to the relevant gas inlet nozzle and apply

clamp to tighten the hose. When pipeline gas is adopted, gas company

should apply corresponding hose where meter with flow value more than 3

m

3

/h is recommended.

• Purge air from the gas supply pipes.

• Test gas circuit for tightness in accordance with current regulation.

Use appliance only with type of gas, stated on the marking plate!

The maximum inlet gas (G20) pressure must be limited to 25 mbar.

Minimum gas (G20) pressure must be higher than 17 mbar.

rustproof material.

• Horizontal part of the exhaust flue pipe

shall have 1% inclination. There shall be

Φ=10 mm hole at the lowest point of the

vertical part of the pipe for the purpose of

draining water drops.

• Distance between exhaust flue pipe and

any flammable materials should be more

than 150 mm. If the exhaust pipe needs to

go through flammable material or wall,

heat shield should be used.

• The exhaust flue pipe should be fixed

thoroughly.

INSTALLATION INSTRUCTIONS

Commissioning

Once the gas water heater installation has been completed, it is necessary to

commission the appliance as follows:

1. Gas supply installation:

Inspect the entire installation including the meter, test for tightness and purge

in accordance with current regulation.

2. Water supply installation:

Inspect the water pipe installation for water tightness.

3. Make sure that type of gas complies with the type of gas stated on the rating

label.

4. Open the air inlet in the room.

5. Check if the exhaust flue pipe is correctly installed.

Lighting the appliance for the first time:

1. Open the battery compartment on the bottom of the gas water heater and put

two batteries in (2 x type D battery).

2. Ensure that the gas inlet valve and cold water inlet valve below the appliance

are open.

3. Open the hot water tap and ensure that air is purged from the appliance and

the pipes.

4. Turn on the on / off switch.

5. Turn the gas regulating knob to its maximum position.

6. Turn on a hot water tap.

The appliance will attempt to ignite, should this fail due to air in the gas pipe.

Several ignition attempts may be required to light the gas for the first time. If a

problem comes up after normal operation, turn off the water immediately. Re-

try 10-20 seconds later to avoid ‘pop’ burning.

Do not touch the housing of the gas water heater during operation. During

operation only setting knobs can be touched.

INSTALLATION INSTRUCTIONS

Repair and maintenance

Note:

All the repair and maintenance must be carried out by authorized technicians. The

maintenance of the water heater must be fulfilled at least once a year. It is

recommended to carry out the maintenance after a period of heating operation. The

maintenance and repair must be kept in record. Before cleaning or maintenance and

repair, please take off battery from the water heater and turn down the gas valve.

Only the original spare parts for maintenance can be used.

If the spare parts used for maintenance are not original, the manufacturer does not

assume any quality guarantee. The connecting pieces must be new.

To ensure safe and effective operation, the appliance must be serviced

once a year by a Gas Safe registered engineer.

1. Daily maintenance done by the end user:

• Check the gas pipe regularly for leakage or any defect. If in doubt contact service

center.

• Clean water filter on cold water inlet regularly.

• Check water leakage regularly.

• When flame turns from blue to yellow with black smoke, close the gas valve and

call service center immediately for help.

• Check the exhaust flue pipe frequently to avoid the jam. If the exhaust gas cannot

go outside it can lead to CO poisoning.

• Check the ventilation.

• Check the appearance of the appliance.

• Check if any strange sound occurs during usage.

• When you plan not to use the appliance for a longer period of time, close the gas

and water valves and remove the batteries from battery compartment.

2. Anti-freeze protection

Should the appliance be installed where pipes are subjected to freezing, it is

recommended to empty it.

Proceed as indicated below:

• Turn the outer electrical switch to the OFF position.

• Close the gas valve.

• Close the cold water inlet valve.

• Open the DHW taps until both the appliance and pipes are completely

emptied.

• Screw off the drain valve on water inlet connector.

To resume operation, tighten the drain valve, open the cold water inlet isolation valve

together with DHW taps until water flows steadily from all taps.
