Venting A Gas Water Heater Through Wall

Likely it would have to be some specific minimum distance from any.

Venting a gas water heater through wall. Direct vent water heaters. The buyer wants to replace the electric water heater with gas. Atmospheric venting refers to a system in which exhaust from the water heater naturally rises out of the appliance s combustion chamber then travels up through a standard chimney style flue. Exhaust gases are vented outdoors through a separate vent duct or through a separate chamber of the same pipe this requires a double wall vent duct.

With a direct vent system air for combustion is drawn from a vent pipe that runs through an exterior wall or the roof. The air that is used for combustion will come from the water vent this vent will either through the roof or from the outside of the wall. The direct vent water boiler is another type of water heater venting that you should know about. A power vent water heater will cost about the same as a tankless heater and avoiding a through the roof vent can make the difference in a tankless installation being affordable or not.

This vent also allows for off gasses to be unleashed outside too. I recently inspected a split level home with a utility room that includes a 90 efficiency furnace and an electric water heater. The question is does it have to vent through the roof.
