I've never seen anything like this.
The S Trap was blocked with almost a solid lump of carbon that was shiny, lik coal, when I broke it up.
Has anybody any idea if there is a fault causing this?
Symptoms, lockouts, and listening to the flue outside a sound of gurggling water,inside lots of vibration, boiler fires but poor heat output.
Thanks
Derek
