Possible Causes

Restricted air intake or exhaust, Incorrect gas pressure, Dirty or misaligned burners, Wrong orifices for gas type (natural vs LP)

How to Fix / Troubleshooting

Safety first: Turn OFF power and gas immediately. Do not continue to operate a sooting heater.

  • Check venting and intake: Ensure the exhaust vent and combustion air intake are clear and properly installed per Poolworld specifications.
  • Inspect burners: Remove and clean burners with a soft brush. Ensure all ports are open and burners are seated correctly.
  • Verify gas type: Confirm the heater is configured and orificed for the correct gas type (natural gas or propane). Using the wrong orifices is hazardous.
  • Have combustion tested: A qualified technician should check gas pressure and perform a combustion analysis to adjust or correct issues.

Warning: Sooting can lead to carbon monoxide production. Do not use the heater until the problem is resolved.
