SAFETY DEVICES

Spark Safety Device: Automatically shuts unit down when there is an abnormal spark at time of ignition. Display lamps “LOW”, “60”, and “64” will activate if this happens.

Flame Failure Device: Activated when burner flame fails, indicator lamp “ON” flashes. If burner fails to ignite, indicator lamp “60” flashes. This prevents raw gas from being released.

Overheat Switch: This device automatically cuts the gas off if the heater exceeds a predetermined temperature. This is normally caused by an obstruction in front of the louvers, or a blocked fan filter. Indicator lamp “68” “ON” and the “FILTER” indicator lamp flash when overheat switch is activated.

Two Fusible Links: Backs up the overheat switch. If the fusible link cuts the unit off, a service call by an authorized person is required to replace the link. Indicator lamps “68” , “FILTER” and “ON” will flash.
