HOW TO USE THE VENT GRAPH

The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the re-
lationship between the vertical and horizontal dimensions
of the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Side wall Vent Graph, Figure 20, lo-
cate the point intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the fire-
place in accordance with same.
EXAMPLE A:
If the vertical dimension from the floor of the unit is 11' (3.4
m) the horizontal run to the face of the outer wall must not
exceed 14' (4.3 m).
EXAMPLE B:
If the vertical dimension from the floor of the unit is 7' (2.1
m), the horizontal run to the face of the outer wall must not
exceed 8' (2.4 m).
Refer to Page 26 for snorkel requirements.

SLP PIPE

When using SLP pipe it is not necessary to use sealant
on the joints.
To join SLP pipe together, simply align the beads of the
male end with the grooves of the female end, twisting the
pipe until the flange on the female end contacts external
flange on the male end. NOTE: Sealant is not required to
assemble fireplace venting. Do not use silicone sealant at
the inner flue exhaust connections.
1. Attach the First Vent Component to SLP Starting
Collars
To attach the first vent component to the starting col-
lars of the appliance:
•
•
•
•
2. Commercial or High-Rise Applications
For installation into a commercial or high-rise appli-
cation: All outer pipe joints must be sealed with high
temperature aluminum foil tape, including the slip sec-
tion that connects directly to the horizontal termination
cap.

Figure 21–
Adding Venting Components
Note: The end of the pipe sections with the lances/tabs
on it will face toward the appliance.
VENTING INSTALLATION
Lock the vent components into place by sliding the
pipe section onto the collar.
Align the seam of the pipe and seam of collar to allow
engagement. Rotate the vent component to lock into
place. Use this procedure for all vent components.
See Figure 21.
Continue adding vent components, locking each
succeeding component into place.
Ensure that each succeeding vent component
is securely fitted and locked into the preceding
component.
Only outer pipes are to be sealed. Do not seal the
inner flue. All unit collar, pipe, slip section, elbow
and cap outer flues shall be sealed in this manner,
unless otherwise stated.
1 - Align Seams
2 - Rotate
