8.
Install Downdraft Diverter and final row of Side Walls
(
Figure 15
). Then place #3 rebar (8 each, 36 inch long)
vertically through the cells until they reach bottom. Position
them adjacent to the rebar or all-thread sticking up from the
hearth.
9. All components must be level. Mix approx. 2 cu. ft. of Ready-
Mix Concrete. Fill all cells with Ready-Mix Concrete mix.

10. Set the Lintel and Lower Rear Dome as shown in
Figure
16
. Check that all is level. If adjustments are needed, use
shims and fill gaps with an appropriate amount of mortar.
Note:
Although you are cautioned to use MASON-LITE
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 17
. The
beveled face lines up with the inward angles of the lintel
sides. Resulting top surfaces should be level.

12. Verify that the smoke dome side, front and rear walls 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 appliance
alignment before continuing to the next step.
13. Assemble Upper Dome and Dome Sides as shown in
Figure 18
. 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. Be sure that it is
flush in every direction 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”
.
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
appliance (see
Figure
19).
