Specifications
Match the badge in front of you to a row before you use any of this. Every figure below was read from the Baxi literature listed under Sources at the foot of this page, checked 6 September 2026. Outputs, variants and part numbers change by year, so the appliance data plate is still the last word.
| Variant | GC number |
|---|---|
| 600 Combi 2, 624-2 | 47-077-55 |
| 600 Combi 2, 630-2 | 47-077-56 |
| 600 Combi 2, 636-2 | 47-077-57 |
- Baxi's published GC numbers for the 600 cover the Combi 2 boilers. Read any other 600 format off the plate rather than assuming from the badge.
- Register within 30 days of installation. Baxi limits the warranty to 12 months from the installation date on the Benchmark checklist where the registration, Benchmark and annual service conditions are not met.
Where the data plate is
Above the boiler controls. The serial is the field marked s/n on that plate, and it is repeated on the user information label.
Reading the plate
Worth knowing on site
- Sits below the 800 on features and warranty.
- Confirm the exact configuration and output from the data plate.
On the tools
Sitting below the 800 on features and warranty, the 600 is the range engineers typically fit when a customer wants an everyday, no-frills Baxi rather than the flagship. It is a common choice on straightforward combi and system swaps where budget is the main driver.
Variants and configuration
Like the 800, it covers combi and system formats, but with a narrower feature set. Because Baxi's numbered ranges are distinguished mainly by warranty and finish rather than a completely different design, always confirm the exact model and output from the data plate.
Where it sits in the range
The 600 occupies the middle of Baxi's current numbered range, positioned below the 800 and above the older 400. It is typically fitted where a customer wants a modern Baxi combi or system without paying flagship pricing.
Finding the manual and the data plate
For the exact outputs, gas rate, dimensions and commissioning figures, work from the appliance’s data plate and the manufacturer’s installation and servicing instructions. The GC (Gas Council) number and serial are on the data plate, usually behind the front panel or on the underside. Baxipublishes its manuals and support at Baxi support.
