Bit of a state
Appears to be because the gasket had gone here, melted the condensate adaptor then turned the leaking condensate into steam and prematurely rusting the internal parts of the boiler.
The secondary heat exchanger was spotless and got called there as it wasn't lighting, the arse end of the nozzle was black. Took 3 hours to clean and took a grinder to the baffles and going back in the morning.
