A method of ventilating a boiler system (10) during boiler system outages includes shifting (64) to the ventilation system (11) by stopping (70) the boiler system induced draft fan (32), closing (71) an internal isolation damper (19) in the boiler system ductwork (14), opening (72) a ventilation isolation damper (18), and starting (73) a ventilation fan (12). At the completion of the outage, before resuming operation of the boiler, the ventilation system (11) is secured (64) by stopping (80) the ventilation fan (12), closing (81) the ventilation isolation damper (18), opening (82) the internal isolation damper (19), and starting (83) the induced draft fan (32).
