Installation of Horizontal Extensions
1. Cut a 5-1/2 inch (13.6 cm) diameter minimum clearance hole in the wall at
the point where the vent-air intake tubes will pass through the outside wall
and connect with the direct vent-air intake terminal. (See Figure 11).
Figure 11
2. From outside the building, position the outer wall mount plate and direct
vent-air intake terminal over the center of the opening. Mark the mounting
screw hole locations. With a 3/16 inch diameter drill bit (not supplied), drill
holes for the wall anchors (supplied). Install the wall anchors but DO NOT
affix the outer wall mount plate and direct vent-air intake terminal to the
wall at this time. (See Figure 12). Note: Certain construction of walls
may require the use of a different type of wall anchoring means than
supplied. DO NOT modify the direct vent-air intake terminal or outer wall
mount plate.
