NORMAL SEQUENCE OF OPERATION
On a call for heat, the thermostat will actuate, completing the circuit to the aquastat. The completed circuit to the aquastat will first activate the circulator and damper which will close an end switch inside the damper. This action will complete the circuit to the ignition system and ignition will take place.
In the event the boiler water temperature exceeds the high limit setting on the boiler mounted aquastat, power will be interrupted between the aquastat and the ignition system. The power will remain off until the boiler water temperature drops below the high limit setting. The circulator will continue to operate under this condition until the thermostat is satisfied.
In the event the flow of combustion products through the boiler venting system becomes blocked, the blocked vent safety switch will shut the main burner gas off. See figure 18, page
17.Similarly, if the boiler flueway becomes blocked, a flame rollout safety switch will shut the main burner gas off. See figuer 18, page 17. If either of these conditions occur, do not attempt to place the boiler back into operation. Contact a qualified service agency.
