Autumn is the perfect time to give your wood fire a little love and attention. As the crisp mornings settle in, it’s a timely reminder to ensure your log burner is clean, safe, and ready for the cold season ahead.
Regular cleaning and inspection are key to improving heat output and performance, avoiding smoke damage and breathing hazards, preventing chimney fires and extending the life of your wood-burning unit. If you’re asking how often I should clean my fireplace in NZ, the general recommendation is to inspect and clean at the start and end of each burning season, or more often with heavy use.

Ash and debris build-up inside the firebox reduces your heater’s efficiency and can become a fire hazard.

To prevent any leaks.

- Inspect the gasket for signs of wear, cracking, or flattening

To ensure optimal airflow.
The damper regulates the airflow and influences how quickly your fire burns. It should open and close smoothly, without sticking.
