You don't need a boiler section blowup to know how to move radiation or system gpm quantities. This information is independent of boiler construction, other than input and tappings (which are generous in Peerless boilers.)
An explanation of design procedures is available at http://www.hydronic.net The flow rate in gpm for the whole system will be the net heat absorbed from the fuel into the boiler divided by 10,000. If the flow rate is correct, the water will return to the boiler 20 degrees cooler than the water temperature leaving the boiler. This is explained in detail.
