This is from above, don't know how much the CA code differs (I am using Rick's post because his highlighting with bold is applicable to your question and installation).

Does not say anything about "the bracket" manufacturer's instructions, just 'the upper and lower 1/3' and "the appliance" manufacturer's instructions.
In my opinion, 'the hot and cold supply' does not fall into "in the upper one-third", the hot and cold supplies would fall 'above' the upper 1/3.
