Why does my Protemp Sun-Stream PT-70-SS-A shut down after a short time?

If your Protemp Heater fires up but shuts down quickly, several factors could be at play. It might be due to a dirty fuel filter, a dirty nozzle, or a dirty or defective photocell, or the photocell might not be correctly installed. Check the wiring between the circuit board and photocell. Additionally, an obstructed cooling fan could cause this issue. Ensure the cooling fan isn't blocked.
