APPLICATION
Z-VENT
®
Double Wall with ZV-Clamp
™
is a factory built, engineered AL29-4C
®*
gas venting system suitable
for venting positive or negative pressure Category I, II, III, IV residential and commercial gas fired heating
equipment. The maximum allowable continuous flue gas temperature for Model SVE is 550°F (288°C ).
CONSTRUCTION
The inner flue is manufactured from super ferritic AL29-4C
®
* stainless steel. The AL29-4C
®
* alloy shows
excellent resistance to chloride ion pitting, crevice corrosion and stress corrosion cracking, making it the
ideal choice for battling the effects of high temperature flue gases and corrosive condensate from high
efficiency gas heating equipment. A unique built-in gasket system provides air and water tight connections
with no sealant required. Leakage tested to 2½ times the UL listed pressure rating of 8” water column.
The double wall system has a one inch air space between the vent walls providing an insulation factor. This
reduces clearance to combustibles and helps to maintain stack temperature, an important feature in the safe
venting of modern high efficiency heating equipment. The outer wall is fabricated from Type 304 stainless
steel. Fusion welded components provide superior fit, reduced turbulence and flow resistance.
Also eliminated are crevices and other spots where condensation can collect and corrode the vent.
Optional 316L Stainless Steel is available where the vent is installed in potentially corrosive environments;
such as room with chemicals present, providing increased corrosion resistance to the outer casing.
MATERIAL SPECIFICATION
