1. Remove hex head sheet metal screws at lower edge of
front panel (4); pull panel outward and down to
detach.
2. Lift 1/2" white blanket-type insulation (5) up and
drape over top of unit.
3. Remove front aluminized steel (8).
(NOTE: To catch brick debris and to protect the
flooring, we recommend laying the unit
shipping box in front of the unit before
loading the brick.)
4. Begin brick loading with Row 1 starting with the right
side and working toward left. Follow with the upper
layer of the back row in the same manner. Make sure
that all bricks are flush with the back aluminized steel
(9) and the brick indentation is facing the front of the
unit (See Figure 5).
5. Next, load Rows 2 and 3 using the same method
reversing brick indentation as required to
accommodate heating elements (54). Again,
make certain all bricks fit flush against the
previous rows of brick.
BRICK STACKING

•Brick Loading
GENERAL NOTES:
A. Room Units and ceramic heat storage bricks (13) are packed separately. The bricks are
shipped in boxes of four (white box) and boxes of five (brown box). One box of each is
required per element bay or nine bricks total. Refer to Table 3 for the total number of
bricks required in model being installed.
B. All bricks for the Steffes ETS room units are identical. One side of the brick is indented to
accommodate the factory installed heating elements. Bricks are inserted in rows four deep
and two high. Bricks are “loaded” by maneuvering them around the elements taking care to
bend elements as little as possible.
CAUTION: Use NIOSH/MSHA approved respirator, gloves, and long sleeved garments
when handling insulation materials in accordance with generally accepted
safety practices.
