Code requires the relief valve's discharge capacity to equal or exceed the input of the appliance it protects, so compare it against the input rating on the heater's data plate. Zurn's own spec sheet separately lists a 300,000 BTU\/hr ASME Section IV pressure-steam figure for this exact model - a different, much larger number measured on a different basis.
