I don't know about changes in corgi regs but I know glow-worm recently issued a bulletin to say they didn't approve any replacement case seals except the genuine part. I'm pretty sure baxi wm's are the same aswell if not all of them. Can't really see how or why the manufacturers would approve aftermarket safety seals.
because often the seals are no longer avialable, providing the seal makes an adequate seal and passes a co test around the boiler, ratio checks are ok the the boiler is no longer at risk, or dangerous. if a classic as a defected seal around the casing i can use an isar case seal, its the same thing different boiler, different seal but its ok to use them as long as there is no spillage. thank you
