Turn the fan switch to position II (for heating) and make sure that the fan is turning. After a brief
preventilation the flame ignites.
Regulate the gas flow pressure according to the thermal power desired, by turning the wheel of the
pressure reducer anticlockwise to increase the pressure or clockwise to decrease.

check that all the prescriptions of the previous paragraph about installation have been observed.Wait one
minute , then unlock the heater by pressing the RESET button and repeat the starting operations.
Contact your supplier should any problem continue.
