Venting

Installation continued-

This is a Direct Vent Gas Water Heater where all air for combustion is obtained from the outside atmosphere and all flue gases are discharged to the outside atmosphere.

WARNING

The vent-air intake system must be properly installed. Failure to properly install the vent-air intake system properly could result in property damage, personal injury or death.

DO NOT install any damaged vent-air intake system components. Contact the manufacturer of the water heater for replacement parts.

Direct Vent-Air Intake Terminal (See Figure 4)

∙Shall be installed with at least a 9 in. (22.9 cm) vent termination clearance from any air opening into a building.

∙The bottom of the direct vent-air intake terminal shall be located at least 12 in. (30.5 cm) above grade.

∙Installed at least 3 ft. (91.4 m) from any gas meter, gas valve or other gas regulating equipment.

∙Must be installed in a location where it will not be blocked by snow.

Note: Provide protection of the building materials from degradation by flue gases from the direct vent-air intake terminal.
