IMPORTANT

The Terminal Elbow and Wall Penetration Section included in the snorkel kit have gaskets in the female end of the outer pipe. These gaskets prevent infitration of rain water into the air intake section. Do not interchange with similar components shown in Table 7.4b.

a)Cut a 6” diameter hole through the exterior wall at the planned exit point of the vent. A minimum of 4” is needed between the center line of this hole and grade to install the lower wall bracket.

b)Before mounting the lower wall bracket, loosen the M10 x 35 screw on this bracket. Adjust this bolt forward or backward so that its center is 6-7/16” from the wall (Figure 7.34) and tighten.

c)Center the Lower Wall Bracket on the hole in the wall and mark the location of the four mounting screws on the wall. 5/16” mounting screws (not supplied) are recommended for mounting this bracket. Drill mounting holes and mount the bracket.
