Hi
I had my boiler serviced and was told the fan pressure was -4.9.
The manual says pressure "must be greater than -4.9. Pressures below indicate that the heat exchanger will require cleaning".
The engineer said it will be fine until next year when it is recommended I have a strip down service. Is this sound advice or does it actually require cleaning? I have a feeling it was cleaned last year by BG but cannot be 100% sure.
Many thanks
