2.8 Function
This gas heater is equipped with automatic electronic
ignition to simplify operation.
B To activate, just turn on the switch (Fig. 8).
After this, automatic ignition occurs whenever a hot
water tap is opened. First, the pilot burner is lit and
approximately four seconds later the main burner
ignites. The pilot burner flame is extinguished after the
main burner lights.
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.
