This Enviro vent reducer (part 50-4022) is the option that steps 8 in. x 11 in. co-axial direct venting down to 5 in. x 8 in. on the Urbana U33 and Urbana U44. It is required equipment for power vent installations on these models, letting the larger co-axial run transition cleanly to the smaller vent size at the appliance connection.

Fit

• Enviro's Urbana power vent manuals call for this reducer on the U37 and U44, with the vertical power vent manual adding the U33I.
• For 4 in. x 6 5/8 in. venting, choose the 5 in. x 8 in. to 4 in. x 6 5/8 in. reducer, part 50-2321.

What it adds

The reducer gives the venting run a factory-made, properly sized transition piece rather than an improvised fitting, matching the dimensions Enviro specifies for power vent setups on these Urbana models.

Specifications

• Steps down from 8 in. x 11 in. to 5 in. x 8 in.
• Listed by Enviro as Vent Reducer 8 x 11 in. to 5 x 8 in.
