A: This works with the following models : H250IDL2, H350IDL2 and H400IDL2, so it depends on your exact model.

A: I would need to know the Model number and serial number of the Raypak heater. Raypak has been around for a long time and makes a variety of different heaters. In the interest of time you can call me with that info and I will find out and then call you back. Chris 978 651 3301
