Initial Installation

QUALIFIED INSTALLERS ONLY

When planning your installation, it will be necessary to select the proper length of vent pipe for your particular requirements. It is important to note when passing through a wall, the maximum allowable wall thickness is 10 inches (25.4 cm); 11⁄2 inches (3.8 cm) clearance to combustibles must be maintained. Select the amount of vertical rise desired for “vertical-to-horizontal” type installations. To determine the length of vent pipe required for vertical installations, measure the distance from the appliance flue outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow for sufficient vent height above the roof line. For two story applications, a fire stop is required at each floor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the venting system to the appliance flue outlet, a twist-lock adapter is built into the appliance at the factory.

Refer to INITIAL INSTALLATION - VENT CONFIGURATION AND RESTRICTOR SETTINGS for venting parameters.

Your total vent pipe length must be within the grid area of Figures 28 and 29. If a 90° elbow is used in the horizontal plane, 36” (91.4 cm) must be subtracted from the allowable horizontal run.

There are three (3) basic types of Direct Vent System installations. The three (3) types of installations are shown in Figures 24 through 26.
