Operating Instructions and first operation test
Note to installer: You must test the operation of this appliance after installation.
1.
Pressurize the water system by turning on pump or city water pressure.
2.
Purge all air from system by turning on the taps until a steady stream of water flows
from the taps. Turn off taps.
3.
Turn on the 12 VDC power supply.
A testing sequence on the remote starts and after a few seconds, the display shows
the last selected temperature. The production preset water temperature of the water
heater is 45° C. The selected water temperature is stored in nonvolatile memory.
Even after disconnecting the electric power, the former selected temperature will be
displayed. This is a very useful feature as you don't have to select your desired
temperature again in case of a power loss.
For colder (blue button) or warmer water (red button) press the buttons till you reach
the desired temperature.
4.
Turn on the gas supply at the tank and the manual gas valve if installed in system.
Heater will remain dormant (and will not use any gas) until a water tap is opened and
the heater senses a water flow of at least 2.5 l/min.
5.
Turn on the hot water tap (water flows and/or pump starts). The heater will fire up within two
seconds and hot water will start to flow from the tap in the time that it takes to get through the
plumbing from the heater to the tap. Hot water delivery will continue as long as the water is
flowing. Depending on the length of the hot water line, it might take up to 20 seconds until
the hot water comes out of the tap.
After the first installation or when you change the gas bottle, it might need 3-5 trials, until
the gas has reached the burner and you have ignition. On the display failure E1 is shown,
which means no flame detection. When E1 appears, just turn the water tap on and off to
trigger a new ignition sequence.
After the burner ignites you will see the current temperature on the display. Depending on
the water flow and the ambient temperature of the cold water, it will take some seconds,
until the control reaches the desired water temperature.
6.
When you turn-off the hot water tap, the heater will shut off and remain in "stand-by mode".
7.
With the ON/OFF button of the remote control, you can switch off the water heater so the
burner is not activated via the water flow.
