• Do not apply belt dressing, which can cause damage and early belt failure.
Inspect and Clean
Flow Switch
Inspect and clean 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 ProSHOT Product Support at 1-800-
969-7073.
4) Observe the Shuttle Assembly and internal portion of Body for obstructions, hard
water deposits and any other foreign debris. Remove the foreign debris with light
scraping or compressed air. If no additional cleaning is required continue to Step
7. If additional cleaning is required continue to step 5.
5) Remove the Body from the plastic Enclosure and soak the Body in CLR or
similar solution to dislodge excess buildup. The screws (QTY 5) in the Enclosure are TORX T10.
