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.

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). Insert batteries correctly.
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.

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.
