It's more violent than just a sound. The whole boiler shakes.

Hi, My combi has started shaking intermittently during the recent stormy weather almost as if air pressure is getting trapped in through the flue somehow.(sounds a little like a washing machine on spin in the next room) If I turn the thermostat down, it stops and then runs normally when I turn...

Thanks eveyone.

What would happen if it was fully open or closed?

Please let me know if you guys need more info
