SUPERIOR SYSTEM DESIGN
eVent™DualSeal™with RapidLock™Connection System is a modular
double wall prefabricated vent and exhaust systems used in venting
high efficiency appliances that require a positive, neutral or negative
draft exhaust. The Patent Pending joint connection system ensures
quick and leak free connection with the industry’s highest pressure
rating. Connections are sealed with factory-applied gaskets and
pressure tight v-bands designed specifically to handle the temperature
and corrosive condensate produced by high efficiency appliances.
eVent™is a double wall product that utilizes AL 29-4C®or 316L inner
liner providing exceptional corrosive resistance meeting appliance
manufactures warranty requirements. A 1" air gap between the inner
and outer shell provides low clearance to combustibles and insulation
properties to improve natural draft. Schebler also offers 2" insulated
product, eVent™PLUS2, that provides enhanced insulation properties,
see eVent™PLUS2 brochure for more information.
LISTINGS AND VENTING APPLICATIONS
The Schebler eVent™DualSeal™leak free system is tested and listed
by Underwriters Laboratories Inc. (UL) under file number MH10056
for UL 1738 and ULC S636-95 vent. eVent™is a double wall special
stainless steel venting systems for gas fired appliances listed as
Category II, III, and IV with a maximum flue gas temperature of
550˚F, and 40" w.c. positive pressure. Gas vent - BH, Class I /
Class II - 245˚C.
COMPLETE LINE OF FITTINGS AND SIZES AVAILABLE
The eVent™series is available in even and odd diameters ranging
from 5" to 48". A complete line of straight sections, variable lengths,
tees, elbows, stack terminations, roof penetration components and
support members are offered. In addition to the standard components,
virtually any conceivable fitting is available as a special order item.
MATERIAL AVAILABLE
eVent™is available in a variety of materials allowing the proper
material selection for your specific application. The standard product
features AL 29-4C®or 316L stainless steel liner and a 430 stainless
steel outer shell.
SUPPORT LIMITS
Support plates and wall supports are utilized to support the weight
of the vent. In horizontal runs, supports should be placed adjacent
to fittings that are not otherwise supported. See the individual part
description for allowable support charts.

JOINT ASSEMBLY
1. Join the non-gasketed flange to the gasketed/collared flange of the
next section. Install inner band around the two flanges, and use a
3/8” nut driver to tighten inner band around sections. Tap on inner
band with rubber or rawhide mallet to ensure a proper tight joint.
2. Rotate flange bolt into the corresponding notch of the clip and
tighten both flange bolts evenly until secure.
3. Place outer band around both sections covering the space between
the shells. The flanges on the outer band fit into the grooves on the
shells. Use a 3/8” nut driver to tighten into place.
3
Ensure factory supplied gasket is in place and in
good clean condition. Damaged or missing gaskets
should be replaced before flue is installed.
Contact your Schebler exhaust system distributor
for additional gaskets.
