We have an old 30 year old Smith Cast iron 8 series boiler that is running dirty and shutting down. HVAC guy cleaned the box, replaced the injector, the cateye, readjusted the igniter, changed fuel filter (twice), and new tank with new copper lines, the old buried tank had failed. Cleaned out a very dirty chimney. What could be cause this, fuel pump, fan maybe? Thanks
