Element Wire Conguration (Multi-watt models RM151, RM162 and RM168 only)
STEP 1
Cadet’s Multi-Watt RM heater offers a variety of heat output options. You must rst determine the desired wattage and then congure
the heating element wire connections. The heater is shipped from the factory congured for maximum watts: 1600 Watts (240V) and
(208V) for RM162 and RM168, and 1500 Watts (120V) for RM151. If this is the wattage you desire, proceed to STEP 2.
On models RM151, RM162 and RM168, mark wiring diagram on the back of the heater with the wattage used for future reference.
Install Heater Assembly
STEP 2
Set the heater assembly (blower wheel rst) into the left side of the wall can. Fasten at top with screw provided. Unlace heater lead
wires. Connect the supply wires to the heater wires (See Figure 9). Keep all wires away from element connections when wires are
pushed into free space on right of heater.

Secure grill with the screws provided. If you have a built-in thermostat model, slide thermostat knob onto shaft. Turn power on at the
electrical panel board.
