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.

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.

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.
