It is the responsibility of the general contractor to

FIREPLACE INSTALLATION
STEP 2: MIXING AND APPLYING MORTAR
FIREROCK ADHESIVE MORTAR
FireRock Adhesive Mortar must be used when building the
FireRock fireplace for your FireRock warranty to be valid
Use of other mortar will void your FireRock warranty
This mortar is available from your FireRock dealer or
distributor This specially formulated mortar is a low
sand polymer modified with heat resistant additives and
is designed to work as a “glue” rather than a typical joint
provider
MIXING THE MORTAR
Mix FireRock Adhesive Mortar with clean water
according to the instructions on the bag until it results in
a “toothpaste” consistency free of lumps or dry pockets
Be sure it is not too thin or runny to ensure maximum
strength Use only clean water when mixing FireRock
Adhesive Mortar Do not use spirits or antifreeze agents
Do not apply if temperatures are below  F or will be
within a  hour period
APPLYING THE MORTAR
It is appropriate to use a trowel or grout bag to apply the
mortar to firebox and smoke chamber joints These joints
should be COMPLETELY COVERED BY ¹₂”  ” OF
MORTAR Figure  and the components stacked so
as to result in a ¹₁₆” to ¹₈” joint The excess mortar should
push ooze out and be scraped away
BUTTERING THE JOINTS
At each level of the firebox smoke chamber and masonry
chimney it is important to go back and “butter” all joints
This procedure involves a final smoothing of any excess
mortar inside and out sealing all joints and ensuring a “no
leak” installation Figure 

FIREPLACE INSTALLATION
STEP 3: FIREBOX ASSEMBLY
BASE PLATE
The base plate must be placed on a level noncombustible
surface It is very important that your base plate be square
to the intended viewing area properly centered and level
Mark out the position of the base plate on the supporting
floor system Apply a layer of mortar to the area and set the
base plate Figure 
Whether using a flush hearth or a raised hearth a
noncombustible hearth must extend at least ” out in
front of the finished firebox opening and ” beyond the
finished sides of the opening Figure  on page 
FLUSH HEARTH (FIGURE 5.2)
If the design calls for a flush hearth you can omit the base
plate from the assembly instructions and build the side
walls directly on the concrete pad or slab In the event you
opt not to use the base plate carefully chalk lines where the
base plate would be to ensure proper placement of your
firebox
With a flush hearth the firebrick floor of the firebox will be
applied directly to the concrete slab or pad This makes the
finished firebrick floor approximately  ¹₂” above the top of
the slab or pad
RAISED HEARTH (FIGURE 5.3)
If the design calls for a raised hearth the base plate should
be set on a noncombustible platform that is built up to the
desired hearth height
When calculating the hearth height be sure to account for
both the  ³₄” base plate and  ¹₂” thick firebrick floor in
addition to the height of the platform

If building an Arched Front unit read page  before
installing the final course of the firebox
LEVELING AND ALIGNING COMPONENTS
It is important that each course of the firebox is level
and flush with adjoining components FireRock mortar
is not intended to create a mortar joint of any thickness
for leveling purposes Leveling and alignment adjustments
should be made by the use of small shims Be sure to re
mortar any gaps resulting from the shims to maintain a
leakfree seal
