A new Leisure oven gives off a strong chemical or paint smell on its first few uses.

Safety: This is usually normal for a new oven but should not produce visible flames or heavy smoke.

• Burn-in cycle: Remove all packaging and accessories. Heat the empty oven to around 220–250 °C for 30–60 minutes with good ventilation (windows open, extractor on).
• Repeat if needed: If odour persists, repeat the burn-in once or twice more.
• Monitor: If the smell is extremely strong, acrid, or accompanied by smoke from a specific area, switch off and inspect for leftover packaging or a fault.
