Simpson Dura-Vent Type B Features & Benefits
- HEAVY GAUGE ALUMINUM LINER provides fast warm-up for a quick,
strong draft and corrosion resistance for safe, trouble-free performance
- MALE & FEMALE ENDS ARE HEMMED to add structural integrity, preventing
ovalization. Hemmed edges also eliminate sharp edges that can cause job
site injuries. The inner liner is recessed to avoid damage in handling
- DIE FORMED ENDS provide consistent fit, easy twist-lock assembly, and
proper alignment
- INVERSE BEADS add rigidity and ensure proper spacing between the inner liner
and the outer wall. The inverse beads also serve to seal the air chamber between
the inner and outer walls. As a result, the inner liner heats up rapidly and
remains hot during the operation of the appliance, minimizing the effects of
condensation
- Do not use Type B Vent for Category II, III, or IV gas
appliances
- Always refer to gas appliance manual and all local and
national codes!
