Hello am new and in dire need.. i have a old potterton prima 50b boiler.. it was working well a bit noisy. called plumber for service and since then experiencing very severe explosive ignition.. had the pilot readjusted and clean. gas pressure and burner pressure are correct and set.. the flu is correct.. there is no heat blockage in the heat exchanger.. the seals around the casing are correct.. and its still persisting. What else could it possibly be? Could it be a gas valve letting by? Help . thanks in advance
