Assembly Instructions - (cont.)
Step 7: With the damper beams assembled and mortared
together, set the cast iron throat damper (unless another
damper type is being used) on top of the damper beam and
over the smoke chamber opening. The cast iron damper’s
operating plate should face toward the rear of the replace.
(Figure 17) The ange 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 nal
position proceed to Step 8.
Note: A Damper is not required for exterior installations.
Step 8: Position the cast iron damper so that its front ange
is approximately one inch (1”) away from the inside face of
the front smoke dome component. (Figure 17)
Run a thin bead of mortar around the four sides of
the cast iron damper or tack the corners of the ange to avoid
movement of the damper as it gets opened and closed. Set
the rear smoke dome component across the damper beam
in a bed of mortar and ush with the back face of the back
damper beam lintel. (Figure 18)
Set the Isokern Standard front smoke dome
component in mortar across the front damper beam and ush
with it. Set the Magnum front smoke dome component in
mortar accross the front damper beam and 2 -1/4 inches
back from the front of the front damper beam lintel. This
placement should create a space of 17 inches (17”) between
the front and rear smoke dome components.
Step 9: Position the smoke dome’s sloping sidewalls at each
end of the smoke dome components. (Figure 18)
The sloping sidewalls t in between the front and
rear smoke dome components and also t into the haunches
at the ends of the front and rear smoke dome components.
Mortar all contact surfaces thoroughly. The smoke dome
sloping sidewalls have a beveled bottom edge so that they
will sit tight onto the at top of the damper beam assembly.
Step 10: Make sure that all component contact surfaces have
been properly sealed with approved mortar.
Check smoke dome front and rear 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 top plate into position on top of the smoke
dome wall assembly. (Figure 19)
One side of the top plate shows a thickened center.
This side is the bottom face.
The ue hole in the top plate is centered in the
smoke dome from side to side but is offset from front to back,
the center being 10 3/4” from the back of the rebox.
Make sure that the top plate is set so that the ue
hole is closer to the back wall of the smoke dome assembly.
Be sure to set the smoke dome top plate ush 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 ue components.
