Notes:
1. Static pressure drops of accessory components must be added to determine total static pressure for fan selections.
2. Gas heat section maximum temperature rise of 60°F.
3. Economizer static pressure value for sizing supply fan is the highest of the following: a) Return air static pressure drop plus customer return duct static pressure and b) Outside air static pressure drop.
