1. Spark cable disconnected.
2. Blocked venting
3. Blocked condensate drain.
4. Insufficient gas line pressure
5. Flame rod disconnected
6. No 120VAC to Spark Generator.
7. Faulty Spark Generator
8. No 24VAC to Gas Valve.
9. Faulty Gas Valve
1. Ensure that the high voltage spark cable is securely connected to the spark generator and the igniter electrode. Check that the green ground wire is securely attached to the ¼” quick connect tab on the igniter electrode.
2. Check for blockage of the exhaust-vent, air-inlet, combustion blower, gas valve venturi, burner heat exchanger etc.
3. Clean condensate trap, inspect condensate drain for blockages and build-up – correct accordingly.
4. Ensure the manual gas shutoff valve is open. Refer to Section 9.0 GAS VALVE AND BURNER SETUP.
5. Verify that the flame rod signal wire is securely attached to the flame rod and the Sola controller.
6. Check wiring from Sola controller to spark generator. With an AC voltmeter measure voltage across J5-6 and ground (the Sola controller chassis is connected to the 120VAC supply ground) during trial for ignition.
7. During trial for ignition check for arc on spark electrode via the observation port located next to the spark electrode in the burner door. If the spark generator is receiving 120VAC and no spark is observed, replace the spark generator.
8. Check the wiring harness for loose or interrupted connections of the gas valve wiring. With an AC voltmeter, measure the voltage between Sola controller terminals J5-2 to J4-10. There should be 24VAC present during trial for ignition, if not replace Sola controller.
9. The gas valve emits an audible click when it switches on or off. If the Sola controller is providing 24VAC to the gas valve, and the wiring is intact, it should be possible to detect if the valve is responding.
