location of diaphragm on Halstead Ace HE 24 boiler?

I read the procedure on this page for changing the diaphragm, but for the life of me I can't locate the housing?

I suspect yours might not have a diaphragm but instead has a flow switch.Look in the manual if you have it or go online and download one
