Specifications

Direct vent water heaters use concentric venng.

Combuson air is drawn from outside through a

5” diameter vent pipe. Combuson gasses are vented to

outside through a 3” diameter pipe.

Direct Vent

All combuson air is drawn from

outside the home and exhaust

gas is vented to outside using a

concentric vent.

Power Vent

All combuson air is drawn from

inside the home and exhaust gas

is power vented to the outside

using PVC pipe.

Power Direct Vent

All combuson air is drawn from

outside the home, and exhaust

gas is vented outside, oen via

PVC pipe. A concentric vent or

separate pipes can be used.

Atmospheric Vent

All combuson air is drawn from

inside the home and exhaust gas

is vented using metal pipe.

Direct vent water heaters also depend on the buoyancy of

hot combuson gasses for proper venng but are

generally used where vercal venng is not possible or

desirable. Because they draw their combuson air from

outside the structure, they do not waste condioned air

from inside. The most important consideraon with direct

venng is that the water heater must be located very

close to an exterior wall.
