SPECIFICATIONS
Note: DOE Heating Capacity ratings are shown. Where the boiler and piping are in the heated space, the boiler may be selected on the basis of the
Heating Capacity. Where a piping loss and/or pick up loss will exist, add this loss to the building loss to determine the total heating requirement.
Where a piping loss only will exist but cannot be calculated, multiply the calculated building loss by a 1.15 factor to determine the total heating
requirement. Design Working Pressure: 30 PSIG, Water Only.
