Literally the only useful video on TH-cam on these boilers.

Two screws on the top of the boiler, one on either side will release the top panel for access to the heat exchanger bud 👌🏼

Thanks bud, looking to do the same to my cdi42 boiler.. we can't use the DHW as it goes over temp every time..so will do both the burner and the DHW exchanger 👍

4.05 To make it easy to unscrew the screw 13 on the back there is a little trick. The upper casing of the boiler consists of two parts. so you unscrew the two screws at the top and pull the plate off

God bless 🙏

Great video and very informative, I wanted to ask where did you get your training from? Did you use to work for British gas?

[@Smokeblow]

Top man 🫡

[@stevenjohnson6082]

the top casing comes off for easy access to the top of heat exchanger

[@macpatel7810]

Another good one CP. Well explained as usual. Do you need to do a negative fan pressure check on these to determine whether they need to be stripped down and cleaned ? Or do do you strip and clean regardless ?.
