Possible Causes

How to Fix / Troubleshooting
Safety: If you see smoke or strong burning smell, switch off power and gas immediately and ventilate the area.
- 1. New installation check: A mild smell during the first few hours of operation can be normal as oils and dust burn off. This should dissipate quickly.
- 2. Inspect for discoloration: With power off and cover removed, look for browned or melted plastic near the fan, wiring, or PCB.
- 3. Check ventilation: Ensure the Beretta heater has the required clearances and that ventilation openings are not blocked.
- 4. Technician inspection: A professional should test fan current draw, inspect wiring, and replace any overheated components.
