It is important that vents and vent
connectors be installed only in
accordance with simpson dura-vent
installation instructions. A major cause
of fire related problems with vents and
vent connectors is the failure to install
with required clearances (air spaces) to
combustible materials. Read through all
of these instructions before beginning
your installation. Failure to install
the connector as described in these
instructions will void the manufacturers
warranty and may have an effect on your
homeowners insurance and UL listing.
INTRODUCTION
DuraConnect & DuraConnect II are
flexible aluminum connector systems,
with built-in twist-lock fittings for fast,
easy professional installations. No more
cutting, crimping, fitting, or fastening
with screws. Adjustable in length, simply
twist-lock, bend, and connect for an 80%
labor savings!
As safe as it is easy to install,
DuraConnect is the first and ONLY single
wall connector tested and listed by
Underwriter's Laboratories. DuraConnect
& DuraConnect II are UL listed for 1
inch clearance to combustibles, and
are flexible enough to insure greater
earthquake safety.
DuraConnect & DuraConnect II are
engineered venting systems, developed
using the Battelle Laboratories Vent
II Computer Program, plus extensive
laboratory and field testing. The inside
diameter of DuraConnect corrugated
flex system has been oversized 1/4 inch
to equalize flow resistance to that of
smooth wall pipe. By eliminating the use
of elbows, DuraConnect & DuraConnect
II systems further reduce flow resistance.
Due to the high thermal conductivity of
aluminum, DuraConnect & DuraConnect
II systems heat up rapidly. This reduces
condensate "wet time" by up to 50% - a
significant factor in vent corrosion.
DuraConnect & DuraConnect II are
designed to combat condensate
corrosion, a common problem
with galvanized steel connectors.
DuraConnect (single wall) and
DuraConnect II (double wall) are
constructed of aluminum flex - providing
the same metallurgical protection and
proven performance as the inner liner
material in Type B Gas Vent.
APPLICATIONS
The DuraConnect & DuraConnect II
flexible connector systems may be
used as a connector between the gas
appliance outlet and a double-wall
Type B gas vent or masonry chimney.
DuraConnect & DuraConnect II flexible
connectors may be used with both
draft hood equipped appliances and
fan-assisted Category I appliances. Gas
appliances may be connected as a single
appliance, or in multiples, provided the
connectors and the vents are properly
sized. DuraConnect & DuraConnect II
systems may be installed in conditioned
and unconditioned spaces. Refer to
National Fuel Gas Code for restrictions
on location and operation of equipment
and vents. DuraConnect & DuraConnect
II systems can not be installed in attic
spaces. DuraConnect & DuraConnect
II systems may not be used to pass
through walls, ceilings, floors, or other
combustible materials.
