What it is
The Baxi 720776001 is a 4.9mm diameter injector classed as an injector in the burner category of Baxi gas boiler spares. It meters gas into the burner assembly, where it mixes with air ahead of combustion.
Before you order
- Confirm your boiler model and, for Potterton Promax Ultra 33 Combi ErP units, check the serial number ending against the fit list.
- Check whether your installation runs natural gas or LPG, as the DUO-TEC 2 Combi 33 GA is listed separately for each.
- Compare the existing injector's marking and diameter with the 4.9mm specification before ordering.

Fitment listings are a guide, not a guarantee. Plant-room assemblies get modified on site more often than not. Send us the GC number off the data badge and a photo of the existing valve and we will confirm before anything is dispatched.
