Flame Roll-Out Safety Switch

The boiler is equipped with a cut-off device to prevent flame roll-out in the event the heat exchanger becomes blocked. This is a "manual reset" type roll- out switch, that must be reset by a service technician after any over temperature conditions have been fixed. Excessive restriction in the heat exchanger flue pas- sage may cause the switch to disable the boiler.
