Cleaning Flow
Switch

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 Product Support at
