What to do if Eclipse TA cannot initiate a start sequence?
- H
  Heather BaldwinAug 11, 2025
  If your Eclipse burner won't start, consider these potential causes: * The air pressure switch hasn't made contact: Check its adjustment, the air filter, blower rotation, and outlet pressure from the blower. * A high or low gas pressure switch has activated: Check incoming gas pressure and adjust if necessary. Also, check the pressure switch setting and operation. * There's a malfunction of the flame safeguard system or no power to the control unit: Have a qualified electrician troubleshoot and correct the problem. * The main power is off: Ensure the main power to the system is switched to the 'on' position.

What to do if Eclipse TA goes out when it cycles to high fire?
- J
  Jordan AndrewsAug 16, 2025
  If the Eclipse burner goes out when cycling to high fire, it could be due to: * Too much gas to the burner: Verify gas orifice size for your fuel. Verify chamber pressure for proper air flow effect. Check the start-up settings. Measure the gas pressures and adjust them where necessary. Check for valve train pressure loss. * A leaking loading line to the ratio regulator (if installed): Repair the leak.

How to fix weak or unstable low fire flame on Eclipse TA Burner?
- B
  Beth MedinaAug 20, 2025
  A weak or unstable low fire flame on your Eclipse burner could be caused by: * Not enough gas flowing to the burner: Adjust the gas control valve to increase the gas flow. * Not enough air: Check for proper blower rotation and check the air filter for blockage.

Why Eclipse TA start-up sequence runs but burner does not light (continued)?
- S
  Stephanie KochAug 25, 2025
  If the Eclipse burner start-up sequence runs but the burner still doesn't light, it could be due to: * No flame signal: Inspect and clean the sensor, replace if necessary. * Broken flamerod or dirty UV scanner lens. * Flamerod grounding out: Verify that the flamerod is installed correctly and is the correct length. * Too much gas: Wrong or missing burner fuel orifice. Check ThermAir Data Sheets, Series 114 for fuel orifice and the given fuel.

Why is Eclipse Burner unstable or produces soot or smoke?
- J
  Joshua SmithAug 29, 2025
  If the Eclipse burner is unstable or produces soot or smoke, it is likely that the air/gas ratio is out of adjustment. Measure all the gas pressures and air pressures, then compare these pressures to the documented initial start-up settings and adjust them where necessary.

Why Eclipse TA Burner cannot achieve full capacity?
- P
  petercollinsSep 3, 2025
  The Eclipse burner might not reach full capacity due to: * A blocked air filter (when equipped with Ratio Regulator): Clean or replace the air filter. * Gas pressure going into the burner is too low: Adjust the gas pressure. * Combustion chamber pressure is too high: Derate burner for positive pressure installations.

Why Eclipse Burner start-up sequence runs but burner does not light?
- N
  nathan62Nov 7, 2025
  If the Eclipse burner's start-up sequence runs but the burner doesn't light, there could be several reasons related to ignition or gas flow. It might be due to: * Attempting to ignite at inputs greater than 40%: Reduce the start point gas flow and verify the control circuit. * A weak or non-existent spark: Verify the ignition transformer is a 6,000 - 8,000 volt transformer. * No power to the ignition transformer: Restore the power. * An open circuit between the ignition transformer and the igniter: Repair or replace the wiring to the igniter. * A dirty igniter: Clean it. * An incorrectly grounded igniter: Clean the threads on the igniter and the burner (do not apply grease). * A broken igniter insulator: Inspect and replace if broken. * Too low gas flow: Check start-up set...
