How to Fix / Troubleshooting
Safety first: Turn off power and gas. Sooting can lead to dangerous carbon monoxide production; do not continue operating the heater.
- Inspect burner: Remove the burner access panel and examine the Kripsol burner tray for rust, debris, or spider webs. Clean with a soft brush and vacuum.
- Check air intake: Ensure the combustion air intake openings on the Kripsol cabinet are clear of obstructions.
- Verify flame color: After cleaning and reassembly, have a qualified technician fire the heater and adjust gas pressure if needed. Flames should be mostly blue with small yellow tips.
- Professional adjustment: Gas pressure and orifice sizing must be checked with proper instruments by a licensed technician.
