The steel angle sits in this notch. The four-inch leg of the
steel angle is in the vertical position and is to be located in
alignment with the front of the firebox. The ends of the steel
angle should not protrude beyond the outer firebox side
wall. Earthcore Adhesive between the steel and the notch in
the top of the side wall is not needed.
6.
The fireplaces come with an eight-inch (8”) thick damper
beam assembly, 4-piece component group that is to be as-
sembled on top of the firebox side walls and backwall.
The damper beam assembly consists of two (2) long lin-
tel pieces and two (2) short damper beam side pieces.
The damper side pieces are designed to sit on the fire-
box side wall between the front lintel and the back lintel.
Each of the damper side pieces is designed specifically for
its own side of the unit. When properly set, each damper
side piece fits flush with the outside face of the firebox
side wall so that its interior bottom edge aligns with the
interior angle of the firebox side wall that it sits on
(Figure
22)
.
The two (2) lintels will be equal to the width of the fire-
place model that they serve. Properly placed, the lintel is to
sit on top of the firebox backwall and flush with it; the other
lintel sits flush with the front of the firebox, spanning the
firebox opening. These components both sit on their
narrow base so that their beveled face points down and into
the firebox interior
(Figure 23)
.
Be sure to Earthcore Adhesive all damper beam compo-
nents to the top surfaces of the firebox. Earthcore adhesive
the contact surfaces of each damper side
component where it meets the front and back damper beam
lintel components.
NOTE:
The firebox and smoke dome are designed to be
fitted with a traditional cast iron, poker-style throat damper
and placed ontop of the damper beams during installation.
However, in-line or chimney top dampers are alternative
options. The damper is not included with the firebox.
7.
With the damper beams assembled and Earthcore
Adhesive 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
fireplace
(Figure 23)
. The flange at all four sides of the cast
iron damper should be supported by the damper beam’s top
surface.
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 24)
.
Run a thin bead of Earthcore Adhesive around the four
sides of the cast iron damper or tack the corners of the
flange to avoid movement of the damper as it gets opened
and closed.
