SETTING YOUR GAS
GEYSER TO THE CORRECT
TEMPERATURE
The gas geyser should be set to such a
temperature that you should not have to
add too much cold water. If you set the
temperature too high and have to cool
it down using the cold water, you have
eectively wasted gas. Try set the geyser
so that you only have to open the hot
water tap only.
Start by setting the geyser to 42°C for
pipe runs shorter than 3m. If your pipe runs
are from 3-5m try setting the geyser at
43°C and for pipe runs longer than 5m try
setting the geyser at 45°C. If you nd these
temperatures are not satisfactory then
increase the temperature by 1-2°C at time
until you feel the water is hot enough.
The hottest water temperature will be
from the hot water tap closest to the
gas geyser.
Always remember to test the water
temperature with your hand before use
and remember that hotter water settings
increase the risk of injury.
The gas geyser is tted with a device that
will shut o the gas supply to the burner
if the appliance exceeds normal operating
temperatures at about 75 °C
The appliance won’t operate with a water
ow of less than 3 litres/minute.
If this occurs, increase the water ow.
A GUIDE LINE OF
SHOWERING TEMPERATURES
Body temperature: 35-37 °C
Summer time comfortable showering
temperatures: 35-38°C
Warm shower in winter: 39°C
Hot showering temperature in winter
42°C (most preferred showering
temperature)
Very hot showering temperature in
winter: 44°C
For a bath temperature in winter: 48-50°C
Bare in mind a geyser showing 40°C will
not be the same temperature at the
shower head as it will loose heat travelling
through the pipes, the further the run in
pipes the more heat will be lost. Also bare
in mind the slower the ow rate the more
heat will be lost through the pipes as the
water spends more time travelling to the
shower loosing greater amounts of heat.
