Heater emits a strong gas smell around the unit, especially at startup.

Safety first: If you smell gas, immediately turn off the gas supply at the shutoff valve, turn off power, evacuate the area, and do not operate electrical switches. Contact your gas supplier or emergency services if the smell is strong.

• Do not attempt DIY gas repairs: Gas leaks and combustion issues must be handled by a licensed gas fitter.
• Ventilate area: Once gas is shut off, open doors and windows to disperse any accumulated gas.

Have a qualified technician pressure-test the gas line, inspect the gas valve and burner assembly, and correct any leaks or combustion problems.
