IMPORTANT:
For 950-8804 UC1 Replacement Board Kits: If this is a 950-8804 UC1 board kit and you are replacing an existing UC1 board with this
new board, note Dip Switch settings on existing UC1 circuit board so that those same settings can be positioned on this replacement circuit
board. NOTE: Adhere appropriate included label over existing label in UC1 or SideShot electrical box. Also adhere "Checking Memory for
Last Fault Code" sticker on inside of UC1 or SideShot SS1 Series electrical box. On SS2 Series adhere to underside of electrical box.
For SideShot Series SS1 Models: The Pre-Cycle Prover Status Check is deactivated from the factory on the SS1 Series. Because of the
low set point of the SS1 Fan Prover (as low as .03" w.c.) cross winds may cause the Fan Prover to close prior to a call for heat. Activating the
Prover Status Check on the SS1 may cause nuisance lockouts. Important: Deactivate the Pre-Cycle Prover status check if installing this board
on a new or existing SS1 installation by pushing the #9 dip switch up or "ON" to disable.
For Draft Inducers with the UC1: Natural draft or winds may be sufficient to close the fan prover switch contacts prior to a call for heat
when using the PS1505 fan prover with a draft inducer. Keeping the Pre-Cycle Prover Status Check activated may cause nuisance lockouts.
Important: Deactivate the Pre-Cycle Prover status check if installing this board on a new or existing draft inducer installation by pushing the #9
dip switch up or "ON" to disable.
