Adjustable Length
The Adjustable Length Section serves as a variable length between
other components when specific lengths cannot be utilized and
eliminates the need to cut parts to length. For proper installation, refer
to instructions packaged with the Adjustable Length (See Fig. 7).
Customized Lengths— Cutting Standard Lengths
The Saf-T Vent EZ Seal/EZ 316 system (6"-16") is designed
so that in most cases standard lengths will not need to be cut.
There may arise, however, an occasional situation where
standard lengths and adjustable length slip connectors are
not adequate. In such cases, a standard length of Saf-T Vent
may be field cut.
To custom cut a standard length part:
1. Measure the length of vent needed (Dim A) and add 3
inches to the result (See Fig. 8).
2. Measuring from the female end (end with the tabs)
measure out the distance A + 3" and mark it on the
pipe.
3. Cut the pipe with an abrasive cutoff, plasma, or
compound snips.
To help get a square cut, create a straightedge by
wrapping masking tape around the waste side of the cut
point. If using snips, start the cut at the male end and
follow a spiral path around the pipe until the cutoff mark is
reached.
4. File off any burrs that develop in the cutting process prior
to assembling. If the cutting process distorts the
roundness of the pipe carefully use your thumbs to re-
round the end.
5. Apply high-temperature silicone sealant to the field-cut
joint.
6. Assemble the joint using the procedures above.
7. A hose clamp must be used to retain the tabs.
Vertical and Horizontal Support
For proper installation, Vertical and/or Horizontal supports must be
installed to support the Saf-T Vent. Refer to Table 3 for minimum
spacing distances and the corresponding section for instructions for
installing the support. Note: For all support options, ensure all
minimum clearance to combustibles are maintained. Never drill or screw
through the Saf-T Vent system.
Guy Support Section
The Guy Support is a short section of vent pipe with brackets protruding
from it. These brackets provide a means for attaching a guy line,
threaded rod or similar metal bracing to provide support to the vent
system.
To Install: Connect Guy Section to the vent using standard joint
connection method. Attach guy wires or metal bracing to the brackets
provided on the Guy Section. Anchor guy wires or bracing to the
building infrastructure capable of supporting the load of the vent (See
Fig. 9).
