So i have an in ground spa, it sits in the deck area. I havnt used it for about 6 years, so i went and got a new pump, re-did the PVC and everything worked. But the heating did not. Im using a gas heater and when i turn it on only the pilot turns on, it makes no noise and the main burners dont seem to turn on, i dont actually know how to use the heater properly so maybe im doing somethinf wrong? The flow into the heater is really strong so i know thats not an issue. I put pictures below of the heater if anyone can help me please.
P.S. the pump and heater light are on (orange)
