Flo-Direct Water Heater

If the button is pushed, then the controller will try to open the burner to track the set point, but since there is no
flame, the controller will drive the burner to the fully open position. Then the unit will not light because the burner
is not in the starting (low fire) position. To restore the controller to normal, the circuit for the d-out must be opened
and reclosed. On some Flo-Directs there is a button on the panel for actuator reset; on others the relay in the
control box must be unplugged and re-plugged (opening and reclosing) the d-out circuit. All of the above can be
avoided if the controller is not taken out of “MANUAL” and not switched to “AUTO” when the flame is off. Leave the
“MANUAL” button alone.
NOTE 2: If the heater is running and the controller does not switch from manual to auto mode and begin tracking
the set point (red “MANUAL” light is lit long after the flame is on), then the Veri-Flame controller (green flame
safety inside of control panel) has been improperly reset. The reset button must be in the “out” position. If this
button is pushed once and not twice, then the Powers Controller will not be released to go to high fire.
For additional information please see the Powers Controller program listing, the electrical schematic, and the
Powers Controller manual.
