CVent Terminaon Clearances

This appliance along with the CVent Common Vent System is cered with the Cvent 8-in Wall Terminaon Kit,

(790004) mounted in the orientaon shown below.

Horizontal Terminaon

The exhaust and combustion air terminations must

follow these clearances:

[1] 12 inch minimum vertically from bottom of exhaust

termination to top of intake termination.

[2] 12 inch minimum vertically from bottom of

combustion air termination to ground or anticipated

snow line.

[3] From edge of exhaust termination to edge of

combustion air termination:

Minimum of 36 inches

Maximum of 20 feet

[4] 36 inch minimum from multiple exhaust CVents

There should be a minimum of 36 inches between

exhaust terminations in multiple common vent

installations.

The vent (exhaust & combustion air) terminations must

be in the same pressure zone and face the same

direction.

NOTE: During colder weather when the exhaust tem-

perature is much hotter than the outside air, the

exhaust fumes condense producing water va-

por. As a result a plume of water vapor may be

seen leaving the exhaust.
