Read all instructions before using this heater.
A heater has hot and arcing or sparking parts inside. Do not use it in areas where gasoline, paint or flammable liquids are used or stored.
This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. If provided, use handles when moving this heater. Keep combustible materials such as: furniture, pillows, bedding, papers, clothes, and curtains away from the heater.
To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not use it on soft surfaces like a bed where openings may become blocked.

Installation Instructions

WARNING: Wiring procedures and connections should be in accordance with the National Electric code (NEC) and local codes.

Remove the heater from the carton. The front grille and trim can be lifted off the assembly and placed in carton to prevent damage. Remove screws securing the heater assembly to the recess box and separate. (Figure 1)

NOTE: Mount the heater a minimum of 12 inches (30.5 cm) from the finished floor.

Recessed Installation

The recessed box provided with the heater is designed for attachment between studs placed on 32-inch (81
cm) centers. If different spacing exists, construct a frame to suit the box in order to avoid any vibration and noise caused by loose mounting.
Note the orientation of the box (“TOP” shown on the recess box) and secure to studs using four (4) holes provided on side flanges, ensuring these flanges are flush with the finished surface of the wall. (Figure 2)

Surface Installation

Secure optional surface mount box (Part No. RFF-P8C) by angling screws through holes provided in the rear of surface box into studs or finished surface.
Position the recess box into the surface box and secure it with four (4) screws provided in the parts bag of the surface box.

Supply Wiring and Heater Installation

Insert approximately 15 inches (38 cm) of supply wire into the recess box through the knockout provided in the upper left-hand corner. The wire should be rated for a minimum of 90 oC (194 oF).
Connect the power supply to terminals provided marked L1 and L2. The ground wire should be secured to the green ground screw provided on side of the heater assembly.
All units are factory-pre-wired for operation with a built-in thermostat. If remote thermostat operation is required, follow the appropriate wiring diagram located on inside of recess box.
NOTE: All wiring must comply with the National Electrical Code and local codes.
Secure heater assembly to recess box using eight (8) M4 screws previously removed.

Front Panel Installation

Remove the trim frame from front panel assembly.
If tamper-proof built-in or remote thermostat operation is required, secure the louvered door to the front panel using two (2) M3 screws (not included) through the holes provided. The knob can then be removed and adjustment of the thermostat can be made using a slotted screwdriver through the front panel.
! NOTE: 347V/600V units come a grille that is tampered proof.
Check to see that the fan blade is free to turn and that no residue remains in the unit. Front panel can then be secured to assembly using eight (8) M4.8 x 37 screws provided.
Follow the steps as shown in Figure 3.

Operation and Maintenance

Set the thermostat to the desired temperature and both fan and heat should come on. Note that when the desired temperature is reached the fan operation will continue for a short period after the elements have de-energized in order to remove residual heat from the unit.
The fan motor is permanently lubricated and sealed at the factory and is maintenance-free.
It is suggested that at the beginning of each season the front panel is removed and the wire connection condition is checked and the unit is cleaned of dust and dirt with a vacuum cleaner.
! NOTE: Always open the circuit breaker to disconnect power to the unit prior to performing any maintenance or service operation.

WARNING: Should the Over Temp light come on, disconnect power to the heater or turn down the thermostat fully counterclockwise and call a licensed electrician. DO NOT USE THE HEATER UNTIL THE PROBLEM IS DETERMINED AND FIXED.
