Burner adjustment RS5D - RS5D TL - RS5DF

5.7.1

Combustion head adjustment

The ignition should occur at a low output and not higher than 120
kW.
In order to measure the ignition output:
 disconnect the connector (CN1) on the ionisation probe
cable (see paragraph "Electrical system carried out by
the factory" on page 21); The burner comes on and goes
into lockout after the safety time (3s).
 Perform 10 ignitions with consecutive lockouts.
 Read the total quantity of gas burned on the meter.
This quantity must be equal to or lower than:
3
0.10 Nm for G20 (natural gas H)
3
0.10 Nm for G25 (natural gas L)
3
0.03 Nm for G31 (LPG).
It depends on the burner output and is carried out by turning the
adjusting screw 6)(Fig. 11) clockwise or anti-clockwise until the
notch marked on the regulating rod 2)(Fig. 11) lines up with the
outer surface of the head assembly 1)(Fig. 11).
