4.3 Piping checklists
4.3.1 Piping checklist
WARNING:
• The heating of water and other fluids causes volumetric expansion. The associated
forces can cause the failure of system components and the release of high-
temperature fluids. In order to prevent this, install properly sized and located
compression tanks and pressure-relief valves. Failure to follow these instructions can
result in serious personal injury or death, or property damage.
• Avoid serious personal injury and property damage. Make sure that the flange bolts
are adequately torqued.
• Never force piping to make a connection with a pump.
