Regular ash removal is crucial – aim for at least once a week during periods of heavy use. Removing accumulated ash improves combustion efficiency and reduces smoke.

Never leave burning log burners unattended. Ensure adequate ventilation to prevent carbon monoxide build-up, and keep flammable materials away from the burner’s heat.
