We have recently moved house. When the thermostat in this boiler opens it kicks up a hell of a racket on radio and telephone (wired, not cordless.) If there is a suppressor fitted then it has obviously failed. Ideal's web site has installation instructions for a more recent boiler so the construction is a bit different. I would like to know the sequence of disassembly to the point where the connections on the thermostat are accessible so I can fit a new suppressor.
