How can I stop a Range Powermax 155 high pitch whistle?
How can I stop a Range Powermax 155 high pitch whistle? it lights up ok then after 5 mins it starts, cutting the gas rate down stops it, but at its correct rate it whistles
we had a boiler that was doing this no matter what we tried eventually a new flue sorted it, you need an engineer that knows powermax' very well. dont call me lol

You need an engineer who is familiar with this boiler, as small fluctuations in the gas pressure will cause noises like the one you describe.
