Enviro Cara - Manual (Page 16)

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); 1½ 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.

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.
