PIPING INSTALLATION
NOTE: The most effective means for preventing deterioration from accelerated corrosion due to
galvanic and stray current is the installation of dielectric fittings/unions. The installation of these
fittings is the responsibility of the installing contractor.
1. All integral components have been properly sized to meet design conditions. Piping to the
unit should be sized to meet the design conditions, as dictated by good engineering practices.
2. Connect boiler water supply and return lines to heating coil assembly.
3. Connect the cold water inlet and hot water outlet to the appropriate connections as shown;
refer to the drawing for location and sizes.
