IBV Assembly Instructions (cont.)
Fire Brick Installation:
The manufacturer requires that the fireplace fireboxes be lined
with a minimum one and one-eighth (1-1/8”) thick fire brick.
Thicker fire brick may be used as an option. The pattern for the
fire brick lining is an owner option. Standard N or S type brick
mortar is suitable mortar for the fireplace.
Fire brick mortar needs to be suitable to both adhere
the fire brick to the inside of the firebox and to create the
finished face joints of the brick work. Based on a history of
field applications and experience, a suitable mortar would be as
follows:
Mix:
* 1 bucket masonry mortar (S or N type)
* 5 lbs Earthcore mortar
* Six parts sand (1 1/2 bucket)
* One part Fire Clay (optional)
* Water to a sticky, toothpaste consistancy
These instructions may vary because of different
climates and conditions. The use of good masonry practices for
your area should also be considered. It takes about 25 lbs. of
mortar mix (dry measure) to fire brick line a fireplace.
All required through-wall accesses (gas and electrical
line feeds and combustion air supply access holes) should be
drilled before the required fire brick lining is installed.
Face joints of one quarter inch (1/4”) to three-eights
inch (3/8”) give a good appearance to the finished brickwork.
However, larger face joint dimensions are also acceptable.
Step 1.
Wet mop the inside of the IBV with a damp sponge
to remove dust and loose particles from the interior before
installing fire brick.
Note:
It is a good practice to dip each brick in water before
installing.
Step 2.
Start the fire brick at the front edge of the floor of the
Isokern firebox, proceeding inward toward the back.
Step 3:
Apply C-clamp warning label to center floor brick prior
to mortar, ensuring verbiage is legible from front of firebox.
(Figure 16)
Step 4.
Next, apply fire brick to the back wall of the unit starting
at the bottom of the back wall and working upward to the top
of the back wall.
Step 5.
Finally, set the side wall fire brick by starting at the front
edge of the unit’s side wall and working inward toward the back
wall fire brick.
Important:
Be sure to bring the two high temperature wires
through the lower left hand side wall finished fire brick. The
two high temperature wires need to be accessible for later
connection to the high temperature limit switch wires.
