customers the confidence they deserve in a Flagro product.
Convenience:
The FLE-60RC gives our customers the flexibilty of a 20kW/40kW/60kW heat setting.
The heater is equipped with a fan speed inverter control that provides optimum temperature rise
by adjusting blower output at each heat setting. Colour coded Cam Locks power connections
for easy installation. Remote thermostat option available.
Inlet/Outlet Duct Adapter
The FLE-60RC includes a permanent 20" inlet duct adapter
A maximum of 25ft of ducting can be used on the outlet and inlet of the heater
ONLY 20 INCH DIA DUCTING CAN BE USED ON THIS HEATER
Safety
Always verify that you have proper voltage supply. (575V) It is important to check
the wiring connections inside the heater before plugging in the Cam Locks.
Use a meter to measure volt supply to each cam lock.
Work on the internal systems should only be attempted by a certified electrician and
only when power has been disconnected and can not be reconnected to the heater.
Grounding
The heater is supplier with a cam lock system with a grounding connection and is indicated with a "G"
on the cam lock panel. The heater is also supplied with a grounding nuts found on all panels.
It is very important to double check that all grounding connections are properly secure.
Clearance from Combustibles
The discharge temperature of these units may reach very high temperatures. Maintain minimum
distance from combustible materials as follows:
Top: 6 Inches
Bottom: 6 Inches
Sides: 6 Inches
Discharge: 15 FT

MAINTENANCE
1Every heater should be inspected before each use, and at least annually by a
