WALL GUIDE (WG)
The Wall Guide is used to protect the vertical vent from lateral
wind loads and to allow for thermal expansions. When
assembled, the proper installation location is near a joint but
below the outer band. The outer wall of the vent must be able
to move away from the outer ring of the wall guide. When
properly attached to a combustible wall, the Wall Guide will
maintain the proper clearances to combustibles.
Wall Guides should be equally spaced along the wall at
spacing no greater than 16’ for 5” through 10” diameters
and 24’ for 12” through 48” diameters.
Figure 24 – Wall Guide
CAUTION: Always maintain proper clearances to combustibles
when installing all guides and supports. Keep all insulation
away from required clearance (air) spaces surrounding the
vent. Guides and supports are only suitable for attachment to
non‐combustible construction due to possible heat
conduction.
FLOOR/ROOF GUIDE (FRG)
Floor Roof Guides are used to provide lateral support for the
vent in the roof and floor opening. The Floor Roof Guide is to
be bolted to non‐combustible construction in (4) four places.

SUPPORT PLATE (SP)
The Support Plate offers the greatest strength for support of
the eVent Series Venting System. It will provide vertical
support and will provide for joint alignment and support for
horizontal applications. Locate and secure the Support Plate as
necessary by means of structural ties to the building.
The Support Plate must be secured to structural members of
the building, which can adequately support the weight of the
vent as shown on this page of these instructions.
Figure 26 – Support Plate Attachment
The Support Plate consists of (4) split plate halves and
necessary hardware. The assembly is used to clamp the
inner vee band at a joint connection, and are turned 90
degrees a part as shown in figure 27 below. The notches in
the split plates are to accommodate the inner band end
clips, allowing the "V" to rest solidly on the split plate. The
installation procedure is as follows:
1.
Connect the inner joint to be supported by use of
the inner band as previously discussed.
2.
Connect the upper split support plate halves to the
lower split support plate halves with the provided
hardware. The split plate halves should be oriented
90° as shown below.
3.
3/8” x 1 ½” bolts should be used in all of the inner
clamp flange holes. Tighten all bolts.
4.
Install the special outer half bands provided.
5.
For outdoor installation use silicone sealant
instructions shown in figure 26.
