WARNING: in order to adjust combustion and thermal capacity correctly, the fumes must be analyzed using specific instru-
ments. Combustion and thermal capacity must be adjusted simultaneously, making sure that the values read are correct and
in any case, that they comply with the safety regulations in force.

The Landis control box starts the fan and begins the pre-purging of the combustion chamber. The air pressure switch
controls the correct operation. At the end of the pre-purging phase, the ignition transformer cuts-in followed by the
opening of the gas valves. In case of missed ignition or accidental shutdown, the ionisation probe cuts-in and set the
burner in lockout mode within the safety time.
