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 cor-
rectly and that the surfaces are smooth and uniform.
Make sure connections are covered with an adequate
amount of mortar. Remember that you have the op-
tion of using shims but they must be removed and
any holes filled. Make any adjustments to the fire-
place 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.

13) MM63 onlY: Position Middle Domes so that
outer faces are flush to the lower dome as shown

shown in Figure 46.

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).
