Water heater produces a smell of gas near the appliance, especially during or after operation.

Critical safety: If you smell gas, do not operate electrical switches, do not use open flames, and ventilate the area. Shut off the gas supply at the main valve and evacuate if the smell is strong. Contact a gas emergency service and a qualified technician immediately.

• Do not attempt DIY gas repairs: Gas leaks must be located and repaired by a licensed gas fitter familiar with Weishaupt appliances.
• Leak test: A technician will perform a leak test on all gas joints and the gas valve using approved methods.
• Combustion check: Incomplete combustion issues must be corrected by adjusting or repairing the burner and flue system.
