HEATER ELEMENT
The CerIR™ heating element operates at approximately 1800° F. The element is resistant
to thermal and mechanical shock, and is appropriate for use in both wet and dry
locations. (Figure 4)
The element has an expected life of 2000 hours. When an element burns out, it cannot
be repaired and must be replaced. For replacement, have your heater model number
available and call your dealer or Schaefer Ventilation to order Schaefer part number
HZEL-1500-120.

To replace the element:
Always disconnect the heater from the main electrical supply during installation
and/or replacement of the heater element.
1.
Remove the heater from the wall bracket (HZE-1500W) by removing the two bolts,
washers and nuts from the bracket. (Figure 2 and Figure 5)
Remove the heater from the pedestal (HZE-1500P) by removing the two allen
screws that hold the bracket together (you will need to tip the unit down first).
2.
Place the heater on a level, flat surface. Be careful not to bend the lens (lay the
heater on a soft or padded surface, such as a folded towel or bubble wrap).
3.
Remove the four screws that hold the cover on the junction box. Remove the cover.
(Figure 5 and Figure 6)
4.
Remove the two allen screws that hold the element frame in place. (Figure 7)
5.
Carefully slide the element frame out to one side. Notice the two wires that are
being pulled out of the junction box; feed them out as they are pulled by the frame.
(Figure 6 and Figure 8)
6.
Lay the element frame as flat as possible next to the heater (still attached by the
two wires). (Figure 9)
7.
Disconnect the two lead wires from the two ring terminals on the used element.
Do not lose the hardware! (Figure 10)
