Where to find the model and serial number: on the data label, the printed sticker on the cylinder’s casing. It’s usually near the pipe connections or the controls; you may need to look round the side or open the cupboard door fully.
These two numbers tell us exactly which cylinder you have and when it was made, which usually saves a phone call. Can’t read it? Take a photo of the label below instead. The serial number may also be on the commissioning checklist at the back of the installation manual.
