Attack Gas Leak at Boiler

Boiler emits a strong smell of gas near the appliance, even when not running.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose gas union on Attack gas valve inlet, Damaged gas valve body, Leaking gas pipe connection inside boiler, Faulty sealing of gas train components

Danger: If you smell gas, do not operate electrical switches, do not use open flames, and do not attempt to repair gas components yourself.

Immediate actions:

Turn off the gas supply at the main shut‑off valve.
Open windows and doors to ventilate the area.
Evacuate the building if the smell is strong.
Contact your gas supplier and a licensed Attack service technician from a safe location.

Do not use the boiler again until it has been inspected and declared safe.
