bracket 90° COUNTER-CLOCKWISE, and then push the rear panel
flat against the rear wall of firebox.
5.5. EST-36/EST-42: Temporarily secure the rear panel with one of the
supplied refractory clips and a screw.

the BOTTOM EDGE into the firebox first; then push the panel up
against the firebox wall (see Figure 12, below).
Step 5.Install grate brackets and rear panel.
