
and an Appliance Connector for
DuraConnect. Secure with sheet metal
screws.
TECHNICAL REPORT
UL listing:
DuraConnect is the rst and only
single wall vent connector for gas
appliances that has been tested and
listed by Underwriters Laboratories.
The DuraConnect & DuraConnect II
exible connector pipe and ttings are
tested and listed under the UL category
of "Chimney and Vent Connectors and
Accessories." (UL File # MH14089). UL
mechanical test requirements include:
1. Torsional load testing.
2. Ceiling support and wall support load
test.
3. Load testing of tting attachment of
exible connectors.
4. Load testing of aluminum exible
connectors.
5. Flexibility and cross-sectional area
tests on exible connectors.
6. Puncture tests.
UL temperature test requirements
include:
1. Test Procedure: The ue gas
generator shall be red per UL test
procedure #441 (470 degrees F).
The tests are to be continued until
equilibrium temperatures are reached
on nearby combustible materials. (four
hours).
2. Test Congurations: The vent
connector system is tested in both
a horizontal conguration (one inch
clearance to walls and ceiling), and a
vertical conguration (corner test at one
inch clearance to both walls). To simulate
a close clearance condition, the vent
connector was positioned at several
locations 1/4 inch from combustible
walls and ceilings for the duration of the
tests.
3. Test Requirements: Temperature
rise on combustible materials may not
exceed UL specied limits.
NATIONAL CODES
DuraConnect meets all requirements
for single wall pipe connectors of the
National Fuel Gas Code, ANSI Z223.1,
and as specied under NFPA 54, section
7.7, "Single Wall Metal Pipe", and is
in compliance with minimum wall
thickness requirements for single wall
aluminum vent connectors, section
7.10.2b. DuraConnect & DuraConnect II
meet the requirements of NFPA 211 as
specied under Chapter 5 "Chimney and
Vent Connectors", Section 5-2.1.
DuraConnect also meets the
requirements for single wall vent
connectors, of the Uniform Mechanical
Code. UL test procedures verify that
DuraConnect & DuraConnect II materials,
(which are identical to the liner thickness
of Type B Gas Vent) are "capable of
withstanding the ue gas temperatures
produced by the appliance." (Section C.)
DuraConnect & DuraConnect II are UL
listed at 1 inch clearance to combustible
materials and are in compliance with the
intent of the Uniform Mechanical Code
to limit the temperature rise in nearby
combustibles as per UL Standard #441.
DuraConnect & DuraConnect II meet the
requirements and intent of the National,
Standard, and Uniform Mechanical
Codes. The DuraConnect exible
connector system has been approved by
SBCCI, BOCA and ICBO.
