Flow Switch
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.
Inspect and clean the flow switch as needed
1) Disconnect the swivel fitting from elbow to
the inlet of the coil
2) Disconnect the whole flow switch assembly
including the swivel and removable outlet
fitting where the brass body connects to
hose or tee depending on model
3) Unthread the removable outlet fitting with the
swivel still attached from the flow switch
assembly
4) Remove the shuttle
5) Clean the inside of the brass flow switch body
and the shuttle with water and a soft brush
6) Insert the shuttle into the brass flow switch in
the orientation shown
Note: Aligning the male tabs on the
shuttle to the female guides inside the
brass flow switch body can be difficult
since the shuttle is magnetic.
7) Thread the removable outlet fitting with the
swivel still attached into the flow switch
assembly
8) Thread the brass flow switch body onto the
incoming water flow source (hose or tee)
depending on the model
9) Reconnect the swivel fitting to the inlet of the
coil
