Assembly Instructions - (cont.)
Step 7: With the damper beams assembled and mortared
together, set the cast iron throat damper on top of the
damper plate and over the damper plate opening. The
cast iron damper’s operating plate should face toward
the rear of the fireplace. (Figure 15)
The flange at all four sides of the cast iron
damper should be supported by the damper beam’s top
surface.
Before adjusting the cast iron damper to its final
position proceed to Step 8.
Step 8: Set the back smoke dome component across the
damper beam in a bed of mortar and flush with the back
face of the back damper beam. (Figure 16)
Set the front smoke dome component in mortar
across the front damper beam flush with the front of the
sidewalls.
Position the cast iron damper so that its front
flange is approximately one inch (1”) away from the
inside face of the front smoke dome component.
(Figure 16)
Run a thin bead of mortar around the four sides
of the cast iron damper flange to avoid movement of the
damper as it gets opened and closed.
Step 9: Position the smoke dome’s sloping sidewalls at
each end of the smoke dome components. (Figure 17)
The sloping sidewalls fit in between the front
and rear smoke dome components and also fit into the
haunches at the ends of the front and rear smoke dome
components. Mortar all contact surfaces thoroughly.
Note:
The smoke dome sloping sidewalls have a bev
-
eled bottom edge so that they will sit tight onto the flat
top of the damper beam.
Step 10: Make sure that all component contact surfaces
have been properly sealed with approved mortar.
Check smoke dome front and back walls to see
that they are plumb, level and in alignment with mating
components.
Check alignment of the smoke dome sloping
sidewall components to see that they are fully seated.
Step 11: Set the smoke dome top plate into position on
top of the smoke dome wall assembly. (Figure 18)
One side of the smoke dome top plate shows a
thickened center. This side is the bottom face of the top
plate.
The fourteen inch (14”) diameter flue hole in
the top plate is centered in the smoke dome from side to
side but is offset from front to back.

Make sure that the top plate is set so that the flue hole is closer to the
back wall of the smoke dome assembly.
Be sure to set the smoke dome top plate flush with
the front, back and sides of the smoke dome assembly. All contact
surfaces must be properly sealed with the approved mortar.
Note:
The completed smoke dome assembly should present a stable
and level surface for setting the flue components. (Figure 18)
