Step 3: Continue assembly of the second, third and fourth
courses of the firebox side wall and back wall. Apply mortar to
the top of each layer of wall components, set the next course
above into place. Be sure to mortar all vertical joints of the side
wall to back wall connection when setting each component to
its mate. (Figure 13)
Look for some mortar to squeeze out along the joints
of all contact surfaces as a sign that the joint is thoroughly
sealed with the approved mortar.
Step 4: When all of the STANDARD firebox wall components
are set, check the top surface of the firebox for level.
If necessary, adjust the top surface of the box assembly for level
by inserting a shim between the lowest wall component and the
top surface of the STANDARD base plate. (Figure 8)
Any gap created under the wall components during the
Shim leveling process must be filled with mortar to full bearing
against the base plate.
Step 5: Make sure that the firebox assembly has been set level
and square. Adjust as required while the mortar is still wet.
Make a final inspection of all contact joints in the fire
-
box assembly to be sure they are properly sealed. Fill any and
all gaps in the assembly, as necessary, with the approved mortar.
Step 6: The STANDARD comes with an eight inch (8”) thick
damper beam assembly, a four piece component group that is to
be assembled on top of the firebox.
The damper beam assembly consists of two long lintel
pieces and two short damper beam side pieces.
The two lintels are identical in shape, size and in
length, equal to the width of the STANDARD fireplace model
that they serve.
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 sidewall so that its
interior bottom edge aligns with the interior angle of the firebox
side wall that it sits on. (Figure 14)
Properly placed, one lintel is to sit on top of the firebox
back wall and flush with it; the other lintel sits flush with the
front of the firebox, spanning the firebox opening. These com
-
ponents both sit on their narrow base so that their beveled face
points down and into the firebox interior. (Figure 15)
Be sure to mortar all damper beam components to the
top surfaces of the firebox.
Mortar the contact surfaces of each damper side com-
ponent where it meets the front and back damper beam assem
-
bly lintel components.
