4.2 Metre Inbuilt Zero Clearance Flue Kit
Overview
The 4.2 Metre Inbuilt Zero Clearance Flue Kit is a complete, fully compliant flue system designed for installing inbuilt wood burners into timber-framed cavities where no masonry chimney exists. This kit provides the protected vented flue structure required to maintain safe clearances to combustibles, making it ideal for new builds and renovations.
Engineered for NZ conditions and building standards, the 4.2m kit includes everything needed for a full cavity installation: inner and outer flue sections, zero-clearance shielding, a vented outer casing, ceiling components, roof flashing, and a cowl. This ensures correct draft, fire safety, and long-term durability.
