Once UV sensor has been mounted to sight tube then attach the five (5) pin cable to sensor. Route the
cable through the black plastic heyco cord connector (FH-1310) then through either an existing hole in the
fan/heater control box or drill a new 7/8" hole. Try to keep the cable entrance location close to the relay
and fenwal board.
Find a location to mount the 3" aluminum din rail and relay base inside the fan/heater control box.
Drill two (2) 9/64" holes that will be used to mount the din rail to the heater back panel. Use the two (2)
supplied self-tapping phillip screws (S-2786) in the drilled holes to mount the din rail. Once the din rail is
secure snap the relay base to the din rail as shown in
Figure 7 .
