How to find the right Nefit part

1. The part number on the old part — most spare parts carry the manufacturer number on a sticker or stamped into the part. Enter it in the search and you go straight to the matching item.
2. The rating plate of the appliance — On a Nefit boiler it is behind the front cover, usually at the bottom; the designation looks like TopLine HRC 30 CW6 or ProLine HRC 24 CW4. With the exact model designation you select your series in the catalogue and only see the parts that fit, with the exploded-view drawing and position numbers.
3. In doubt, send a photo — e-mail a photo of the rating plate and the old part to info@instalpunt.com; we look up the part number for you.
