Note: 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 in any gaps, especially joint connections, with the mortar.
Important: Adjustments can only be made while the mortar is still wet when correcting for squareness and leveling.
11)Assemble Lower Dome Sides as shown in Figure
46. The beveled face lines up with the inward angles of the lintel sides. Top surfaces should be level.

As you are connecting each component, be certain you are following the instructions given previously for using mortar. Stop to look at the smoke dome side, front and rear walls to see that they are aligning correctly and that the surfaces are smooth and uniform. Make sure connections are covered with an adequate amount of mortar. Remember that you have the option of using shims but they must be removed and any holes filled. Make any adjustments to the fireplace alignment before continuing to the next step.
12)Assemble Upper Dome and Dome Sides as shown in Figure 46. Check your assembly here. If things are proceeding as they should be, the finished top surface should be flat and level.

14)Finally, set the Dome Top into position (Figure 47, page 27). Be sure that it is flush in every direc- tion as you place it on the crest of the smoke dome wall assembly. After this is done, proceed to section on Installing Damper and Chimney System on page 28.
Note: The chimney hole on the Dome Top is not centered from front to back - it should be offset closest to the rear of the fireplace (see Figure 46).
