d)Complete the vent system inside the structure. The support elbow sits on the M10 x 35 screw as shown in Figure 7.34. Cut the Wall Penetration Section to the length required to connect the interior vent system to the Support Elbow following the instructions on Page 26.
e)Remove the Support Elbow from the Lower Support Bracket and attach it to the Wall Penetration Section. Slip this assembly through the Lower Support Bracket. Connect to the interior vent system.
f)Slide an Outer Joint Gasket over the male end of the Air Intake Section with the tapered edge of the gasket pointing up. Attach the Air Intake Section to the Support Elbow. If necessary, the Air Intake Section can be shortened by cutting the male end as described on page 26. After attaching the Air Intake Section to the Support Elbow, slide the Outer Joint Gasket down over the joint between the two fittings to prevent rain infiltration.
g)Attach the Wall bracket to the wall
h)Slide the remaining Outer Joint Gasket over the male end of the Terminal Elbow. Attach the Terminal Elbow to the Air Intake Section, pointing it away from the wall. Secure the Terminal Elbow to the Air Intake section with a single #10 x 1/2” sheet metal screw (Figure 7.34). Drill a 1/8 hole through both outer pipes to start this screw. Use a drill stop or other means to ensure that the drill bit does not penetrate more than 3/8” into the outer pipe. Do not use a sheet metal screw longer than 1/2”. Slide the Outer Joint Gasket down over the joint between the Terminal Elbow and the Air Intake Section to prevent rain infiltration.
i)Attach the Exhaust Terminal to the Terminal Elbow (Figure 7.34).
6)Vertical Terminal Installation - In addition to the vertical terminal, either a Flat Roof Flashing (PN 230533) or Sloped Roof Flashing (PN 230535) is required for this installation.
a)Determine the center line of the terminal location on the roof. If the roof is flat, cut a
b)Install the roof flashing using standard practice for the roofing system on the structure.
c)If not already done, assemble the venting system inside the building. The last section of pipe needs to be on the same center line as the terminal and within
d)Measure distance “H” from the top edge of the storm collar to the end of the last fitting as shown in Figure 7.35a.
e)Add 1” to distance “H”. Carefully mark this length on the pipe as shown in Figure 7.35b.
f)Cut the outer pipe only at the point marked in Step (e) using aviation shears, a hacksaw, or an abrasive wheel cutter. Be careful to cut the pipe square.
g)Place a mark on the aluminum inner pipe 3/8” beyond the end of the outer pipe (Figure 7.35b). Use a fine tooth hacksaw to cut the aluminum pipe and be careful to cut the pipe square.
h)Make a mark on the terminal section 1” from the cut end of the outer pipe as shown in Figure 7.35b.
i)Slip the terminal section through the roof from the outside. Push into the last section of vent pipe until the mark made in Step (h) is not longer visible. Secure the terminal to the last piece of pipe with three #10 x 1/2” sheet metal screws. Drill a 1/8” hole through both outer pipes to start these screws. Use a drill stop or other means to ensure that the drill bit does not penetrate more than 3/8” into the outer pipe. Do not use a sheet metal screw longer than 1/2”.
j)Secure the terminal section to the inside of the roof structure using the mounting bracket provided with the terminal (Figure 7.35c).
