Boiler and Heating System Piping

Figures 10-6 through 10-10 illustrate typical piping systems. These piping schematics do
not illustrate all of the required concepts and components required to have a proper
installation. Concepts not shown include: prevention of thermal-siphoning (heat traps),
isolation valves, drain and purge valves, etc. It is the responsibility of the installing contractor and system
designer to determine which system best meets the need of the installation and to consider all aspects of a proper
system design. Contractor modifications to these instructions may be required, based upon existing piping and
system design; consult NTI for required assistance (1-800-688-2575).
