ORACLE
chase could be insulated to the top to keep the flue
warmer and increase draft. It is best to locate a chase
away from any overhead obstructions and meet all
clearances from such objects (See Figure 9).
NOTE :
If the chase is enclosed or flashed to a roof as
shown in Figure 9, then the flashing must be vented.
If required by local codes, make certain that the walls
have been properly insulated, vapour sealed and
sheathed with a fire rated gypsum board (See Figure 9).
REMEMBER :
Check local codes concerning installa-
tion requirements and restrictions in your area.
RADIATION SHIELD
A radiation shield must be in place where the chimney
passes through each floor level overhead. This will
assist in retarding any spread of fire and act to contain
the fire within the area below the fire-stop.
OFFSET CHIMNEY
Maximum offset angle:
45°
Maximum number of elbows:
4, resulting in two
(2) offsets.
An elbow may be installed directly on top of the fire-
place if required.
Use the offset option if you need to clear a joist or
pass around a cupboard.
Install the fireplace and chimney as described earlier.
When you require an elbow, proceed as follows:
See the detailed offset chart in the EXCEL installation
instructions.
1. Install the required elbow. Turn it in the desired
direction, and fasten it to the other section with the
3 metal screws provided at the joint.
2. Install the lengths required to obtain the desired
offset. Secure each joint with 3 metal screws.
3. Use another elbow to return the chimney to the
vertical direction.
4. Install a roof support, or an offset support at each
offset to support the weight of the flue (elbows are
not designed to support a flue above an offset).
SEALING
Be sure to seal the ¼" space between the fireplace and
the standoffs with a bead of silicone sealer. (See Figure
13.)
SPARK GUARD
Install a 5" wide piece of sheet metal centered under the
joint between the fireplace and the hearth extension.
This will make certain that sparks can't lodge in the
crack and start a fire (See Figures 2 & 11). Depending
on the allowable height your unit can be raised, the ver-
tical dimension of the spark guard will differ. The mini-
mum depth the spark guard must extend beneath the
ORACLE and the non-combustible material in front of
the fireplace is 2 ½ inches. The "Z" shaped sheet metal
must run the full width of the unit. (See Figure 11.) (Z-
SHAPED SPARK GUARD NOT SUPPLIED).
HEARTH EXTENSION
The area immediately in front of the fireplace must be
protected by a non-combustible material such as brick,
tile, stone, or slate. The protection must extend at least
