FAN 50 PLUS PINS


The FAN 50 Plus Pins is designed to replace the new Suburban® and Atwood® / HydroFlame® Fan Control boards as well as maintain backward compatibility with the Fan 50 Plus, and UIB Fan Control boards which have been available since 1994. This board can also be used to upgrade older furnaces to add the Fan Control feature.

The basic purpose of a Fan Control Ignitor Board is to shut the fan motor off if the board fails to sense a flame after
the third ignition try. Thus, battery drain is reduced and the needless blowing of cold air is eliminated.

The FAN 50 Plus Pins , after shutting the fan motor off, will wait for 1 hour and repeat the whole sequence again before
permanent shut down.

For 12 VDC Furnaces ONLY!

The "Fan Control" feature MUST BE USED for proper operation of this board.

*Note: Fan control boards should not be used in DuoTherm® 900 series furnaces that have the thermostat in
the ground circuit. DuoTherm® furnaces can be rewired to move the thermostat from the ground side of the circuit
to the positive side of the circuit so that the Fan control features of the Fan control or FAN 50 Plus Pins board can be
used. Click here for instructions on how to do this in Adobe acrobat format.

Propane is an explosive gas!
Ignitor boards should be installed by trained service technicians.
