System Commissioning

This section of the manual is designed to be used with the “Commissioning of Integrated Combo System” worksheet. The worksheet is designed to guide you through the start-up process in a logi- cal, step by step method which should minimize the work and time involved in having the system meet the designed parameters.

The following conditions are assumed:

The air filter is in place

All supply diffusers and return grilles are fully open and unrestricted

Hot water is available to the furnace

The drain valve for the heating loop is closed

The shut off valves for the heating loop are fully open

The throttling valve for the heating loop (if applicable), is fully opened

Electrical power is available at the furnace

The return air temperature from the house is approximately 70˚F (21˚C)
