What it is
The Vaillant 509584 is a draught diverter rated at 65 kW, used in the flue path of the Atmocraft VK 654/9 gas boiler. It stabilises flue draught and helps prevent combustion products spilling back into the room under downdraught conditions. It is a serviceable flue component rather than a combustion or water-carrying part.
