Operating instructions
1. Open the battery box underneath the
geyser and insert one D cell battery,
paying attention to polarity.
2. Open the cold water valve that has
been installed on thwe cold water inlet
pipe or turn on the main water supply.
Open the hot water tap which your
new geyser now feeds. You should hear
the water flowing through the geyser, if
the batteries are installed correctly you
will hear the geyser start to ignite if the
gas does not come through it will turn
itself off – this is one cycle. To initiate
another cycle turn the tap off and then
back on again.
3. You can now open the gas cylinder
and any gas shut off valves installed on
the gas line. There may be an air lock
inside the gas line especially for gas
piping which is longer than three to five
meters. To get rid of this airlock you will
have to run the geyser through multiple
cycles until the gas reaches the burners,
it will then ignite. should this not work
after three cylces use the gas bleeder
valve to bleed the gas through.
4. You can adjust the temperature of
your new gas geyser by using the
digital control panel.
5. Try setting your gas geyser between
40-45 degrees Celsius. You should not
need to add “much” cold water if any
at all. This way you are maximizing your
efficiency by not using more gas than
you need to by overheating the water.
For longer runs in water pipe you may
need to make this temperature slightly
higher.
6. Never install this gas applinace indoors.
