1.9 Function
This gas heater is equipped with automatic electronic
ignition which simplifies its operation.
B To do so, just turn on the switch (Fig. 9).
After this procedure, automatic ignition occurs
whenever a hot water tap is opened. First, the pilot
burner is lit and approximately four seconds afterwards
the main burner. The pilot burner flame is then
extinguished after a short period of time.
This is a way of saving a great amount of energy as the
pilot burner only operates for the minimum necessary
time to ignite the main burner, in contrast to
conventional systems which operate permanently.
If thishappens:
B Close and open the hot water tap to repeat the igni-
tion process until all the air has been purged.
Air in the gas supply pipe when the heater
is started up may cause ignition to fail.
