FIREPLACE INSTALLATION
STEP 4: THROAT AND DAMPER ASSEMBLY
THROAT (FIGURE 7.1)
Begin building the throat by placing the radius throat front
and square throat back. Remember to completely cover
each component with mortar 1/2” - 1” thick where it will lie
or butt up against another component. Given the curvature
of our radius throat front to aid in smoke draw, be careful
when placing this piece, as it can roll. Mortar and place the
throat left and throat right pieces to secure it in place.
A piece of angled steel (2” x 2” x ¼” thick) has been
provided with your FireRock fireplace kit. The length of
this angled steel piece corresponds with the overall width
of your firebox model. It should be installed beneath the
radius throat front, across the top of the firebox opening -
angle up for maximum firebox opening, or angle down for
additional “smoke lip” (Figure 7.2).
SETTING THE DAMPER
Upon setting the 4 throat components, a recess (Figure 7.2)
is formed for the purpose of locating the damper.
Place the damper in the recess and over the smoke
chamber opening. The damper’s operating plate should
face toward the rear of the fireplace. If necessary, use
mortar to tack the four corners of the damper into place.
Do not mortar all the way around the damper to create
an air tight seal, as it is important the damper be able to
expand and contract.
Each fireplace uses a different size damper.
• 30” firebox - 24” damper
• 36” firebox - 30” damper
• 42” firebox - 36” damper
• 48” firebox - 42” damper
NOTE
: A damper is not required for outdoor installations.
