every boiler as a GC number which identifies the type of appliance the maker and the model if you can find this on a data plate attached to your boiler then I can do a search for you . The GC number will be in the format 2numbers 3 numbers and then 2numbers . for example 41-789-12 . the data badge may be located in the slide off pod covering the boiler temperature selection switch or more likely behind the white enameled case which is removable without interfering with the safety of the appliance workings,behind the contol pod there is a phillips screw that secures the white case to the boiler the case should then pull forward off its mounting at the top.
