Frequently Asked Questions
What should I do if I have a chimney fire?
Close all air vents on your wood burner to starve the fire of oxygen. Evacuate everyone from the house immediately. Call 111 (Fire and Emergency NZ). Do not attempt to put the fire out yourself. Do not use water on a chimney fire.
How do I prevent a chimney fire?
Burn only dry firewood (under 20% moisture), sweep your chimney at least annually, never overload the firebox, avoid burning rubbish or treated timber, and ensure adequate airflow during operation.
Do I need a carbon monoxide detector with a wood burner?
Yes. Carbon monoxide (CO) is produced by incomplete combustion and is odourless. Install a CO alarm in the same room as your wood burner and check batteries seasonally.
