Bosch Series 6 90cm 5 Burner Gas Hob with Wok Burner and FlameSelect
A 90cm gas hob on black glass with five burners, a 4 kW wok burner on the left and nine defined flame levels on each dial.
The Series 6 PPM9A6I40 is a 90cm gas hob, which in practice means 91.5 cm of frameless black tempered glass with five burners spread across it. That width is the point. Pans sit apart rather than shoulder to shoulder, handles do not clash, and there is genuine room to work between a stockpot and a frying pan.
The 4 kW wok burner sits at the left-hand end, with a 3 kW high-speed burner at the rear right and three smaller burners between them, for 11.5 kW in total. FlameSelect runs across all five: nine precisely defined levels per burner, so heat is chosen by number instead of judged by eye.
Ideal For
A 91.5 cm appliance needs an 85 cm cut-out and a long, uninterrupted run of worktop. Given that, it turns five burners into five genuinely usable positions.
The 4 kW wok burner sits at the left-hand end, away from the others, so a wide pan can be worked without crowding whatever is cooking next to it.
FlameSelect gives nine defined levels on each of the five burners, which suits anyone who wants a simmer to be a setting rather than a guess.
Key Features
The appliance measures 91.5 cm across and drops into an 85 cm cut-out, spreading five burners over far more worktop than a standard 60cm hob.
The left-hand burner is rated 4 kW and set apart from the rest, giving a wide pan its own space and the highest output on the hob.
Each burner steps through nine precisely defined flame levels, so settings can be repeated exactly rather than found again by watching the flame.
Burner outputs of 4 kW, 3 kW, two at 1.75 kW and 1 kW give a total gas connection rating of 11.5 kW.
Full-metal dials at the front lift off for cleaning, so the ring of grease that usually gathers around a knob can be dealt with properly.
Surface mounting needs a worktop of at least 20 mm; flush fitting, where the glass sits level with the counter, needs at least 30 mm.
What the extra width buys you
The difference between a 60cm hob and this one is not just an extra burner. On 91.5 cm there is room between positions, so a wok on the left is not sitting against a saucepan, handles point where you want them, and a large roasting tray or a preserving pan has somewhere to go. Five burners spread over that distance also means the person cooking can stand in front of one without reaching across another.
Setting the flame by number
FlameSelect replaces the usual sweep between low and high with nine defined steps on every burner. In practice that means a setting can be written down, repeated and handed over. A stock that wants three hours at a bare tremble sits at the same level each time, and the 1 kW economy burner at the centre front has the range to hold it. When you do want speed, the 3 kW high-speed burner at the rear right is a dial turn away.
Fitting a 90cm hob properly
The appliance is 91.5 cm wide, 52 cm deep and 5.4 cm high, and Bosch specifies a cut-out of 4.5 x 85 x 49-50 cm. At 22.9 kg it is a two-person lift. The electrical supply is 220-240 V on a 3 A fuse with no plug fitted and a 1 m cord, so an electrician makes the connection. Cleaning is easier than the size suggests: the separable cast iron supports go in the dishwasher and the dials come off.
How It Compares
| Kitchen Need | Bosch Technology | Practical Benefit |
|---|---|---|
| Large batch cooking | Five burners across 91.5 cm | Stock, sauce, potatoes, greens and a frying pan can all run with space between them. |
| Wok cooking | 4 kW wok burner | Set at the left-hand end with its own space, giving a wide pan the highest output available. |
| Long, slow cooking | 1 kW economy burner | A small burner held at a defined low level keeps a stock or a stew barely moving. |
| Repeatable heat | FlameSelect nine levels | Every burner steps through nine set levels, so tonight's simmer is the same as last week's. |
| Open-plan kitchens | Frameless black glass | A dark, flat surface with no trim, and a flush option for worktops of 30 mm or more. |
| Cleaning up | Separable cast iron supports | The supports come apart for the dishwasher and the full-metal dials lift off the fascia. |

The Verdict
Strengths
- 91.5 cm wide with five gas burners
- 4 kW wok burner at the left-hand end
- FlameSelect: nine defined levels on each burner
- 11.5 kW total gas connection rating
- Frameless black tempered glass, flush or surface mounted
- Separable cast iron supports, dishwasher-suitable
- Removable full-metal dials and flame failure devices
Considerations
- This needs a long run of worktop: the appliance is 91.5 cm wide and the cut-out is 85 cm, wider than a standard hob.
- At 22.9 kg it is a two-person lift, and there is no plug: an electrician wires the supply into a 3 A fused connection.
- Flush installation needs a worktop of at least 30 mm; surface mounting needs 20 mm, so check what your counter can take.
