7) When you have arranged all the components into place

and you are working on the top rear firebox, check that

your work is level. If you need to, you can make some

adjustments in the top surface of the box assembly

simply by using shims. Once you are satisfied with the

degree of levelness, you can address any gap that may

have occurred with an appropriate amount of mortar.

Although you are cautioned to use mortar sparingly

because it does have such holding power, you should

look over the firebox assembly at the end and fill any

gaps

with

mortar

Adjustments must be made to ensure the fireplace is level

and square while the mortar is still wet.

8) After fourth row of walls are in place, add 36" rebar to all

cells as shown in Figure 22. The rebar should enter the

holes in the Hearth and lie adjacent to the 12" rebar secured

in subfloor. Then fill cells with approx. 2 cu.ft. Ready-Mix

Concrete.

with each other. Shim if necessary.
