Proper performance and long service life of the Model eVent
Series Venting System requires that the vent be rigidly braced and
supported. Every installation offers unique support and bracing
requirements and the following guidelines will provide minimum
acceptable sizes for the mechanical hardware supplied by others.
When the support plate is bolted to framework 3/8” bolts should
be used in all of the holes on the perimeter of the support plate.
Figure 28 – Support Plate Bracing
INSULATED THIMBLE (IT)
The insulated thimble is used in conjunction with the flashing
and rain collar when clearances to combustibles cannot be
maintained at a roof penetration. The Insulated Thimble should
be dropped through the roof opening. The (4) four tabs will set
upon the roof deck and nailed or bolted down. The flashing is
then set over the Insulated Thimble.

RAIN CAP (CC)
The Rain Cap provides partial protection from rain and debris.
The Rain Cap is mounted on the end of a standard pipe section
with the use of an inner band. A closure ring is provided to
close off the space between the inner and outer liners. A
minimum clearance of 8 feet (2.44 m) is recommended to
ensure that all exhausted products are dispersed away from
the building and intakes. To install the Rain Cap, the following
procedure should be used:
1.
Install the Rain Cap on the inner flange and attach the
"V" band using the inner joint instructions.
2.
Install the provided skirt section as shown below.
3.
Apply a silicone sealant to fill all gaps and joints on the
collar and tighten all bolts.

To clean the flue or replace the Rain Cap, reverse the above
procedure. To reinstall, follow the installation procedure.
