SELECTION GUIDE1. Determine the required amount of replacement air (CFM) by computing the total amount of air being exhausted. (Restaurants should be sized for 90% of exhaust air to minimize food odors.)

2. Determine the total external static pressure by adding the pressure drops through all accessories and ducts.

3. Select unit size and motor horsepower from table.

through the heater by subtracting the winter design temperature from the desired indoor temperature.

2. Values shown in above MBH Input Tables are based on -40° F Inlet Temperature. MBH input shown on unit rating plate will be corrected for actual air density.

3. Natural gas units are limited to 130° F temperature rise, propane units are limited to 100° F temperature rise.

Electrical Data and Sequence of Operation

Sequence of Operation – Return Air Units

Signal from remote control I to AirTrak Controller D, sets operational parameters for dampers B and C, and burner. Damper operation can be manual, building pres-sure or mixed air temperature.

Return air dampers B, and outside air dampers C, are interlocked to move together. As one opens, the other closes. As the return air dampers open, allowing more return air to enter the unit, the out-side air dampers move toward the closed position, decreasing the amount of outside air. Pressure sensor and flow station J, senses change in return airflow and signals AirTrak Controller D.

Modulating gas valve H, regulates gas supply in response to signal from AirTrak Controller D. AirTrak Controller D, varies signal based on input from room tem-perature sensor F, discharge temperature sensor G, and airflow sensor J. Gas valve H can provide approximately 4% to 100% of rated burner capacity.
