Inspect and clean the flow switch as needed
Mineral build-up and/or debris within the flow switch
can occur and may affect burner operation if not
periodically cleaned. Mineral build-up and/or debris can
stop the movement of the shuttle inside the flow switch
body. Shuttle movement is important because the
burner will not fire if the shuttle does not move. The
shuttle movement actuates a switch inside the flow
switch housing which allows the burner to fire during
spray mode.
1) Disconnect the swivel fitting from elbow to the
inlet of the coil
2) Remove the “Cap” fitting from the flow switch.
3) Slide out the “Shuttle Assembly”. If the magnet
in the shuttle assembly is damaged or missing,
replace the entire flow switch assembly. To order
a replacement flow switch assembly, call NorthStar
