The heating mode temperature rise is dependent upon the system airflow, the supply voltage,
and the heater kit size (KW) selected. Use Tables 8-10
to determine the temperature rise(ºF).

208/1/60 Supply Voltage-Temperature Rise Table ºF.
Note:
For installations not indicated above the following formula is to be used:
TR= (kW*3412)*(Voltage Correction)*1.08/CFM
Where: TR=Temperature Rise
KW=Heater Kit Actual kW
3412=Btu per kW
Voltage Correction= 0.96(230 Supply Volts)
0.92(220 Supply Volts)
0.87(208 Supply Volts)
1.08=Constant CFM=Measured Airflow
