GENERAL INFORMATION
Automatic Fan Delay: All models incorporate an automatic fan
delay. When the thermostat calls for heat, fan action is delayed
momentarily until the heating element is warm. When the ther-
mostat is satisfied, the fan continues to operate until the heating
element is cool. This action prevents circulation of cold air, and
avoids exposing unit to residual heat, thus providing higher com-
fort level and prolonged element life.
Optional Controls and Accessories: The following controls and
accessories are available from your electrical distributor.
