UL LISTING
All Schebler eVent series Models are listed to UL 1738 and
ULC 5636‐95 for installations manufactured in even and odd
diameters.
The Schebler Models eVent, eVent SW, eVentPLUS, and
eVentPLUS2 may be utilized in the same system. Proper
installation methods must be followed as called for in these
instructions.
The venting system shall terminate in accordance with the
requirements of CAN/CGA‐b149.1, Natural Gas Installation
code, or CAN/CGA‐B149.2 Propane Installation code.
Refer to The Schebler Company Venting System catalog for
the description of all necessary parts.
VENTING APPLICATIONS
Model eVent SW is a single wall venting system while eVent,
eVentPLUS and eVentPLUS2 are double wall special stainless
steel venting systems for gas fired appliances listed as
Category II, III, & 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 . Models eVent, eVentPLUS and
eVentPLUS2 are also suitable for other applications that call
for an AL 29‐4C vent.
Models eVent, eVent SW, eVentPLUS and eVentPLUS2 are to
be installed as a complete system connecting the
appliance(s) to the outdoors, while operating under positive
forced draft, negative induced draft, or neutral gravity flow
internal pressure conditions using only Schebler models
eVent, eVentPLUS and eVentPLUS2 vent parts. No vent part
from another manufacturer should ever be mixed with
models eVent, eVent SW, eVentPLUS and eVentPLUS2.
If a drain fitting is required by the appliance manufacturer, it
must be located as close to the flue outlet as possible.
Multiple category II, III & IV appliances may not be common
vented unless approved by the manufacturers. Do not mix
natural draft and forced draft appliances together.
Venting systems are to be sized in accordance with the
ASHRAE Handbook, Equipment Volume, the appliance
manufacturer’s instructions, or by contacting The Schebler
Company.
Models eVent, eVent SW, eVentPLUS and eVentPLUS2 shall
not be routed into, through, or within any other vent such
as an existing masonry or factory‐built vent that is
connected to another appliance.
It is recommended that venting systems be enclosed below
the roof line to limit condensation and protect against
mechanical damage. Methods of providing additional
insulation may be specified.
It is required to check the joints and seams for gas tightness
when using the venting system with a Category III or IV
appliance.
Do not exceed the maximum rated pressure for which the
venting system is intended to be used.
Note: Horizontally terminated systems must be pitched
¼" per foot back toward the appliance being vented.
Ensure any condensate is collected by strategically
placing drains, or the appliance itself if permitted by the
appliance manufacturer.
Note: For vertically terminated systems it is
recommended that longer horizontal runs be pitched ¼"
per foot back toward the appliance being vented.
Ensure any condensate is collected by strategically
placing drains, or the appliance itself if permitted by the
appliance manufacturer
.
VENTING ENVIRONMENT
It is suggested that a vent being installed in a corrosive
atmosphere be constructed of Type 304, 430 or 316
stainless steel for the outer shell material.
PART IDENTIFICATION
These instructions and the catalog identify parts by name
followed by a part code. Part numbers are made up of
the model, part code, flue inside diameter and material
code. The part number is shown on the UL label.
EXAMPLE: The part number for a Model eVent (EVD), 47”
long Straight Section (47S), 8” ID (08), with a AL 29‐4C
stainless steel liner and an 430 stainless steel shell (R)
would be EVD‐47S‐08R. eVent Series material codes are
shown in the following chart:
CLEARANCES AND ENCLOSURES
CAUTION – DO NOT PLACE ANY TYPE OF INSULATION OR
COMBUSTIBLE MATERIALS IN THE REQUIRED
CLEARANCE SPACES SURROUNDING THE VENT.
This vent is to be installed unenclosed or with enclosures.
If the vent passes through any zone or story of a building
above that on which the connected appliance is located,
it is to be enclosed in construction having a fire rating
equal to or greater than that of the floor or roof
assemblies through which it passes.
