Brivis ducted gas heaters are built to last, but when a component fails after years of service, the right replacement part gets the system back on quickly without replacing the whole unit. This guide covers every key replacement part in the Brivis gas ducted heater range: gas valves, burner zip tubes, pressure switches, thermocouples, control boards, and transformers. Includes a full component reference table, cross-brand compatibility guidance for Braemar and Bonaire, and selection criteria for every part type.

Brivis, Braemar, and Bonaire ducted gas heaters share a common engineering platform, which means a significant number of spare parts are interchangeable across all three brands. This guide covers exactly which components cross over, including the N-E6 control board, White Rodgers 24V gas valve, and pressure switches across all Pa ratings, what differs between brands such as heat exchangers and wiring looms, and the only reliable method for confirming compatibility before you order: matching by BS part code.

A Brivis heater that won't ignite is one of the most common call-outs at the start of winter — and most faults come down to five key components. This diagnostic guide walks through the full ignition sequence, then covers pilot burner and ignition assembly faults, thermocouple failure, thermistor errors, pressure switch lockout, and control board faults. Includes a fault symptom reference table and guidance on what homeowners can legally diagnose vs what requires a licensed gas fitter.

Ordering the wrong Brivis spare part almost always comes down to one thing — not having the correct part number before placing the order. This step-by-step guide shows you exactly how to find the data plate on your Brivis heater, read BS part codes, confirm gas type (NG vs LPG), identify the correct pressure switch Pa rating, match transformer amperage, and tell the difference between N-E6 control board variants. Get it right the first time.

When a Brivis ducted gas heater stops working, the fault usually comes down to one specific component. This complete guide covers every major spare part in the Brivis range — ignition assemblies, pressure switches, control boards, thermocouples, gas valves, and transformers — including how to identify the correct part by BS code, why gas type and Pa rating matter, and what to check before you order. Covers Brivis, Braemar, Bonaire, and Buffalo platform compatibility.

Buffalo ducted gas heaters run on the same engineering platform as Brivis, meaning a significant proportion of spare parts are directly compatible. This guide explains the relationship between the two brands, which parts cross over reliably (control boards, ignition assemblies, gas valves, pressure switches), and how to confirm compatibility for your specific Buffalo unit before ordering.
