The device is built to function with normal water pressure; in addi-
tion a temperature selector B is also supplied.
Rotate the knob completely to the left to obtain the maximum wa-
ter output or completely to the right for the minimum water output.
The machine is switched off by rotating knob A to the (
position.
When the water heater is not used for long periods close the gas
supply tap or the LPG gas valve on the tank.
For the best operational results it is recommended to have a quali-
fied technician service the machine at least once a year.
Gas economizer
The device is equipped with a gas economizing device which is
used to choose the temperature of the water so it may be supplied
at the temperature necessary while saving gas.
The economizer is activated by rotating the knob (A) in-between
the minimum (small flame
position.
Using the economizer limits the amount of heating when the hot
water usage is modest (water supplied is already warm or there is
a reduced usage, for example in summer).
DANGER OF FREEZING
If there is a possibility that the area where the device is stalled
could reach below 0°C, the device must be emptied of all water
contained.
