SYSTEM OPERATION
S4567A 1001 and S4567B 1017 (see fig. 3.)
When there is a call for heat a self check time (T

switched on.
The ignition spark ignites gas and resulting flame is detected
by the flame rod.
Ignition is switched off after extended ignition time and flame
establishment.
If flame is not established within the safety time (T
ignition control locks out.
If the flame is lost during normal run, the ignition control
