Power Cord Replacement
If the rebox was operating prior to servicing allow at least 
ve (5) minutes for light bulbs and heating element to cool off 
to avoid accidental burning of skin.
Disconnect power before attempting any maintenance or 
cleaning to reduce the risk of electric shock or damage to 
persons.
Replacement Procedure:
1.  Disconnect power and remove rebox from mantel or 
existing replace.
2.  Remove four (4) Phillips screws from the top and rear, 
upper edge of the rebox as shown in Figure 4-A. This 
will release the top cover from the rebox. 
3.  Lift the top cover of the rebox up carefully - the heater 
assembly is attached to the underside of the top cover.
4.  Follow the power cord through the rebox chassis and 
cut all zip ties that bind the two (2) wires of the power 
cord using side cutters.
5.  Disconnect the power cord 
wire which leads to the Main 
Power On/Off (or On/Off/On) 
Switch. This should be the 
only black wire going to this 
switch (Figure 10).
6.  Use a small Phillips 
screwdriver to loosen the 
screw which clamps the 
other power cord lead into the 
terminal block (Figure 10).  
Make note of any additional 
wires that were clamped 
together with power cord.
7.  To remove power cord from 
chassis, use needle nose 
pliers to squeeze sides of 
cable clamp and pull through 
chassis of rebox, removing clamp and cable.
8.  Remove clamp from cable and attach to replacement 
cord, leaving approximately eight (8) inches (20 cm) of 
slack to wire ends (orientate clamp in same manner with 
tapered side facing wire ends).
9.  Feed replacement power cord through chassis hole and 
using pliers, squeeze sides of cable clamp to push clamp 
into sheet metal until snaps in place.
10. Connect terminated wire end to Main Power Switch.
11. Connect crimped wire end to terminal block where 
original was removed (step 6). Also ensure any wires 
freed in step 6 are clamped together with power cord 
wire.
12. Follow steps 1 through 3 in reverse order to reassemble 
rebox.
connectors from the heater element and motor, noting 
their original locations.
iii)  Remove the two (2) Phillips screws from each of the 
two (2) mounting brackets as shown in Figure 7. Do not 
discard brackets.
iv)  Attach the two (2) mounting brackets to the replacement 
heater assembly in the same orientation as in Figure 7, 
using two (2) Phillips screws removed in step iii.
v)  Using the single small Phillips screw from step i, attach 
the cutout to the replacement heater assembly.
vi)  Attach the piggy-back wire from the cutout as shown in 
Figure 8: piggy-back connectors to the lower terminal of 
the heater element, then on to the inner-most terminal of 
the blower motor.
vii)  Attach the last two (2) wires removed in step ii: yellow 
wire will run from the high heat switch to the top, front-
most terminal; the grey piggy-back wire will run from the 
low heat switch to the top, inner-most terminal of the 
heater element then piggy-back to the outer terminal of 
the blower motor (Figure 9).

 WARNING: Improper re-connection of wiring may result 
in electric shock, re, or injury to persons. Ensure that 
connections to/from heater assembly and switches match 
those of the respective wiring diagram for the particular 
model and MOD level being serviced (pages 7-10).

 NOTE: The wire colors referenced in these instructions 
may not be the same as those used in all reboxes. 
Ensure that all wiring matches original placement and/or 
the wiring diagrams that are supplied in this manual.
viii) Follow steps 1 through 5 in reverse order to reassemble 
rebox.
