Pippa can monitor stoves tops up to 3 rings wide (5 or 6 burners). Note that Pippa needs to be mounted at least 70cm above a 3 ring wide stove. Pippa cannot monitor 4 ring wide (7 or 8 ring stoves). We would recommend either you fit your Pippa above the 5 or 6 rings you use most frequently, or use two Pippas, one to monitor each group of 4 rings.
