NOTES: 1. Use Total Static Pressure column that will overcome total system resistance. Approximate pressure drop for component and accessory items; burner 1/2", filter (dirty) 1/2" intake hood 1/8" birdscreen 1/8", discharge louver 1/4", Damper 1/10".

2. NA - Not Available

Selection Procedure:

1. Choose system for 100% outside air.

2. Determine required model size from selection table with desired SCFM of make-up air and MBH input or
     air temperature rise in F. Please note that:

Air temp rise = 920 x MBH Input/10.8 x SCFM

3. For model size selected, read required motor horsepower to overcome total external static pressure   
    resistance.

Also specify type of gas and gas pressure, mounting location, blower, discharge arrangement and motor electric characteristics.
