Heater emits a strong gas smell around the unit, especially near the burner compartment.

Safety first: Immediately turn off gas at the shutoff valve and switch off power. Do not use open flames or create sparks. Ventilate the area and evacuate if the smell is strong.

• Do not attempt repeated starts: Repeated ignition attempts can accumulate gas and create an explosion hazard.
• Check external joints (visual only): Look for obvious loose unions or fittings but do not tighten gas fittings without proper tools and training.
• Contact a gas professional: A licensed gas technician should perform a leak test with approved leak detection solution and repair any leaks.
• Combustion check: After leaks are repaired, have the technician verify burner alignment and combustion quality on the Thermeau heater.
