PRECAUTIONS
1. To prevent gas leakage, always close the main gas supply valve
2. Do not put any flammable items on top of the water heater.
3. If you notice the smell of a gas leak, shut off the gas immediately. Do not turn on / off any
electrical device. Call a qualified service technician
4. Avoid touching the burner inspection window while the heater is on.
5. Check gas pipe regularly for aging cracks etc. as this may cause gas leakage.
PREVENTION OF FREEZING
In winter, if the water temperature drops below 4C, drain the gas water heater completely through the
drain valve to avoid damaging the stove.
Do not allow the water to freeze in the furnace !!!!
If the water heater does not require longer use, please:
-Drain the water from the gas heater drain valve
-Remove the batteries from the battery boxes
MAINTENANCE
• Clean the inlet filter regularly (fig. B 4)
• The heater should be checked for safe operation annually, regardless of frequency of use. This
primarily applies to the correct combustion of the main burner.
• Maintenance should be performed by a qualified and authorized technician.
• If the heater is installed in an area with hard water, the following situations may occur over time. A
decrease in the temperature of the hot water or a decrease in the flow of hot water This is due to the
formation of scale. As limescale formation is proportional to the leaving water temperature to reduce
limescale build-up, it is advisable to use the water and gas control knob to obtain the desired water
temperature instead of mixing cold water with hot water.
TROUBLESHOOTING GUIDE
• Failed ignition - The main gas and / or cold water cock is open Open the main gas and / or cold
water cock
• The ignition of the device does not work. The batteries are exhausted, have been installed
incorrectly, or the power switch is in the OFF position. Reposition the batteries and reinsert / replace.
Turn the device ON
• The control flame ignites slowly / hardly. The batteries have run out. Replace the batteries.
• The water is not warm enough, no flame. Gas supply dynamic pressure too low. Check the dynamic
pressure in the gas connection.
• The flame goes out while the device is in operation. The temperature limiter on the heater has
tripped or the strainer is clogged (Fig. B4), resulting in a drop in water pressure. Wait 10 minutes,
then turn the device on again.
• Water flow too low. Inadequate setting of the flow rate on the controller. Check and adjust
