Boiler inspection and maintenance

START

Room thermostat (control) signals heat requirement

Fan starts.

Ignition spark generator operates

• ignition gas valve opens.

With steady ignition flame

• ignition spark generator stops.

• main gas solenoid valve opens.

Main burner operation

• S 8600 H monitors ignition flame.

Specified thermostat value (control) reached

Main and ignition gas valves close, gas burners go
out. Venting fan stops.

Ignition burner operation

Ignition flame burns, S 8600 H

signals steady ignition flame

ignition flame does not burn, S

8600 H starts ignition attempt,

switches off after 90 seconds.

END

PHASE 1

Ignition attempt

PHASE 2

Main burner

operating

Power interruption

system switches off. Does
system switch on again
when power is restored?

Ignition flame fault

Main gas valve closes,
S 8600 H starts ignition
attempt.
