SHUTDOWN SEQUENCE OF EVENTS

Once the Hearth Focus has reached the normal operating temperature and switched to the “OFF” position, the unit will continue to operate on a much lower setting for 10 minutes. (Approximately half of the “1” setting). After 10 minutes the auger will slow down further and continue at this feed rate until the heater’s “LOW LIMIT SAFTEY” sensor tells the control board it is safe to shutdown.
