Lead-through flange installation and operation manual.
The Harvia WZ020115 lead-through flange lets a 4.6 in smoke pipe pass safely and cleanly through a wall or ceiling penetration. The stainless steel flange provides a secure, heat-resistant collar around the smoke pipe entry point, preventing heat transfer and smoke leakage while protecting the surrounding structure and giving the penetration a finished look.

- Prevents heat transfer and smoke leakage at the penetration
- Protects surrounding surfaces from high temperatures
- High-quality stainless steel
- Limited 2-year warranty (consumer use); limited 1-year warranty (commercial use)

Compatibility
Sized for Harvia’s 4.6 in smoke pipes and the WHP steel chimney system. Remember: a flange dresses and shields the penetration, but non-insulated smoke pipe still requires Harvia’s full clearances to combustible materials, and combustible structures need a proper insulated lead-through.
Good to Know
Does this flange replace the lead-through insulation?
No. Through combustible walls or ceilings you still need the insulated lead-through set (flange, Class A insulation, and protector) supplied with Harvia chimney kits. The WZ020115 collars the pipe penetration itself, typically in non-combustible panels or as the finishing trim.
What pipe size does it fit?
Harvia’s standard 4.6 in (4.5″) smoke pipe used by all Harvia wood-burning sauna stoves except the Harvia 50.
