Strong smell of gas around the Danstoker boiler or gas train, but no specific error code displayed.

Safety: Immediately shut off the main gas valve, turn off electrical power, and ventilate the area. Do not use open flames or operate electrical switches near the leak.

• Evacuate if necessary: If the smell is strong, evacuate the area and contact emergency services or gas supplier.
• Leak detection: Qualified personnel should apply an approved leak detection fluid to joints, unions, and test points on the Danstoker gas train to locate bubbles indicating leaks.
• Tighten or replace components: Carefully tighten leaking joints. Replace faulty valves or sections of pipe as needed.
• Pressure test: Perform a full gas tightness test before returning the boiler to service.

Any gas leak must be handled by licensed gas technicians; do not attempt DIY repairs.
