FIREBRICK WALL INSTALLATION
Continued
GROUTING INSTRUCTIONS
Material provided:
Bag of cement
Bag of sand
Material required:
Piping bag
Joints striker
Heavy duty mixing bucket
Sponge or Wet Cloth
1. Moisten brick surface with damp sponge
or spray bottle just prior to application.
When bricks are wet, any excess grout
mixture on bricks will easily wipe off.
2. In a heavy duty mixing bucket, add equal
parts cement and sand. Add enough water
and mix together well using a power drill
with mixing wand attachment to a yogurt
like consistency. Not adding enough water
can lead to grout falling out after burning.
3. The overall length of piping bag should be
about 16". If the bag is longer than 16",
cut it down to size by removing end with
larger opening. This will make the bag
easier to handle.
4. Put grout mixture into piping bag making
sure the smaller opening is downward and
over a moist towel to avoid spilling. Place
a wet towel over the bucket making sure it
is directly on the surface of grout mixture.
This will keep the mixture moist and it will
not dry out before use.
5. Grout all joints where two firebrick walls
come together.
6. Using a trowel, remove excess grout mix
-
ture by moving trowel in the direction of
the joint. Grout mixture in the joint should
now be flush with brick surface. If not
enough grout is applied into each space,
grout may fall out after burning.
7. Using a joint striker, smooth out grout line.
Allow 72 hours before
operating fireplace.
4. Install the rear firebrick wall last. Place the
wall face side down on the hearth with the
bottom of the wall toward the rear of the
firebox and the top toward the front of the
fireplace. Tilt the wall up toward the back
of the firebox. Secure with 2 rear retaining
brackets provided (Figure 23).

5. It is recommended that the joints between
all firebrick walls be grouted for a more
finished look. See left for grouting instruc
-
tions.
