3. When starting second layer, stagger blocks to
the first layer (see Figure 8). For the MM3FR,
use 8 blocks to build the second layer. After
laying out all blocks, using a level, verify all the
blocks are level. Shim if necessary.
4 When starting the top layer, stagger blocks to
the layer below. Use 7 full blocks and one half
block to build the top layer (see Figure 9). After
laying out all blocks, using a level, verify all the
blocks are level. Shim if necessary.
5. Place 4 heat shield retaining brackets (longer of
the 2 types of brackets included with the MMFRB
Series burner system) on the top layer of blocks
in the pattern shown in Figure 10.
6. Place Block cover over open block in the first
layer for the MM2FR or the second layer for the
MM3FR as shown in Figure 11.
