Limitations & Safety Notes

• This component is specifically for Brivis DF3 and UF series gas ducted heaters; it may not fit or function correctly in other models.

Tradie Pro Tip

When replacing any flue component, a small amount of high-temperature silicone sealant designed for flue pipes can help ensure a truly airtight seal, even with minor imperfections. Don't go overboard, but a thin bead is cheap insurance against exhaust leaks.
