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.
