2. The grill adaptor is designed to be installed underneath
the gypsum board in the wall. In the desired location,
frame a 13" x 13" hole to accept the gravity vent grille
adaptor. Fit the gravity vent grille adaptor into the framed
hole and fasten it into place with nails or screws.
3. Remove the outer cover to the left, right, or both sides
of the flue outlet, on the ORACLE.
4. Cut the insulation to the size of the opening and remove
the cover plate underneath (it is taped in place).
5. Install the B-vent starter section. The slot in the B-vent
starter section should be facing the front and the hole
should be facing the back. Bend up the four tabs at the
base of the starter section to hold it in place.
6. Install the "shut off" damper at the base of the starter
section. The shut off damper enables the manual con-
trol of hot air flowing through the gravity vent pipe. With
the top louvers removed and the angular portion of the
rod in hand, insert the damper rod into the hole in the
starter section. Next, make sure that the washer and
spring on the control arm are both on the outside of the
starter section and that the rod has fit snugly into the
slot. A definite tension should exist between the shut off
damper rod and the starter section. Replace the lou-
vers. The damper rod should protrude above the top of
the louvers.
7. Install the B-vent pipe, between B-vent starter and the
grille adaptor. Fasten each joint with 3 screws. Insert the
B-vent pipe into the grille adaptor and fasten it with three
screws. The B-vent pipe needs only be inserted far
enough to be able to screw it into place. This allows you
about 3 ½" of adjustment.
8. Once the wall facing around the gravity vent grille adap-
tor has been completed, install the grille with the sup-
plied screws. The gravity vent is now ready for opera-
tion.
GAS LOG OPTION
The Oracle now features a gas conversion option. You can
use your choice of gas log sets with this conversion. The
installation of the gas should only be done by qualified per-
sonnel. To convert the Oracle for use with the gas log
option:
1. You will notice a 1 ¼" diameter knockout on both sides
of the Oracle, about 9" up from the bottom of the fire-
place (see Figure 4). The gas line will be installed
through one of these knockouts. Choose the side that
is best for your installation.
2. Remove the firebrick from the base of the firebox. You
will notice two sheet metal pieces underneath the fire-
brick. Remove these also. Keep the firebrick and sheet
metal, as they will be needed to operate the Oracle, if
you would like to burn wood again.
3. Underneath the firebrick and sheet metal, there are four
1" diameter holes in the center of the bottom, to bring air
to the gas log set. These holes must not be blocked.
4. There are two 1 ¼" diameter holes closer to the sides of
the bottom of the firebox. If you are installing a gas
valve, install it over one of these larger holes, to allow
the airflow to cool the gas valve.
5. When you remove the firebrick you will notice a notch in
the bottom of the side refractories. The gas line will
come through one of these notches (see Figure 19).
6. Follow the instructions supplied with your gas log set
concerning the installation of gas lines, shut-off valves,
etc. If you have the sand pan type of gas log set that
covers the air holes, place some of the firebrick, or
some other suitable non-combustible material around
the edges of the sand pan to raise the gas log set above
the air holes.
Maximum gas input: 40 000 BTU
There are no minimum clearances to the sides or top of the
firebox. However, any clearances stated by the gas log set
manufacturer must be maintained.
You may install the gas valve inside the firebox if the gas log
set manufacturer allows this in its instructions, and the
required clearances are met.
