2.0 OBJECTIVES:

The objective of this project is to provide an adequate and reliable heating system at the EC-8. All work will be in compliance with all applicable State and Federal codes and standards with respect to installation, safety, and energy performance. As a final objective, the park expects that the system shall be reliable, robust, high quality, easy to operate, maintain and operate quietly. The equipment, service parts, and troubleshooting listed are commonly used throughout the park.

3.0 BACKGROUND:

It has been determined that the existing heating boiler in EC-8 is not only beyond its design life but also undersized to provide adequate heat to the park offices housed in this building.
