The FES series heaters are designed to circulate room air across its heating elements to gradually
increase room temperature. The best performance results will be obtained when using these heaters
in smaller, confined spaces with low ceilings.
Operation of these heaters is accomplished using the thermostat and fan switch.
You have the option to use the fan only*, or the fan and heating elements together. Position the fan
switch to the “fan” position to circulate room air with no heating. Move the switch into the “heat”
position for control of fan and elements with the thermostat. Maximum heating is obtained with knob
turned fully clockwise**.
This heater is equipped with an automatic fan purge that eliminates residual heat after the
heating cycle . Allow the heater to fully purge before disconnecting power to the heater. This will
eliminate the possibility of cycling the heater on the limit control.
*The thermostat has a preset range of 40oF, there will be no “fan only” function as the
thermostat is always calling for heat.
**Setting the thermostat to high heat versus low heat does not make the unit operate at a
higher temperature. It simply raises the temperature necessary to satisfy the thermostat.
The unit will run longer to try to satisfy a higher thermostat setting.
Note: ALL FES models are equipped with an internal over temperature limit designed to protect your
heater if a restricted airflow condition occurs. This limit device will completely shut down the heating
elements if the temperature limit is reached. The limit must be manually reset when the unit cools.
The reset button is marked and located on the side of the control box near the thermostat knob
on the 45kW models and the opposite side for the 60 kW models.
WARNING:
