CHECKOUT
To check cad cell operation, use the following procedure:
쐃 Disconnect the cad cell leadwires; then start the burner.
Shortly after the burner starts, place a temporary
jumper between terminals F-F. Connect an ohmmeter
across cad cell leadwires; resistance should be less
than 1600 ohms.
쐇 Stop the burner and remove the temporary jumper.
쐋 With the burner off, check the dark cell resistance
across cad cell leadwires. Resistance should be greater
than 20,000 ohms.
NOTE: If cell resistances are different than specified,
recheck the wiring and the location of the cell.
If necessary, replace the plug-in part of cell,

SERVICE AND REPLACEMENT
In normal operating conditions, the C554A does not require
cleaning. If a badly adjusted burner causes heavy
accumulation of dirt and soot on the cell surface, carefully
wipe the cell surface to restore full view of the oil flame.
If the C554A is damaged, replace the plug-in part of the cell.
