cover. See diagram 5.

NOTE: For Snorkel terminations in ABOVE grade installations, follow nation- al or local code requirements.

Below Grade Snorkel Installation If the Snorkel Termination must be in- stalled below grade, i.e. basement ap- plication, proper drainage must be pro- vided to prevent water from entering the Snorkel Termination. Refer to Dura- Vent Installation instructions for de- tails.. Do not attempt to enclose the Snorkel within the wall, or any other type of enclosure.

4)Install wall penetration heat shield in the center of the 9-1/2" round hole and attach with wood screws. The four wood screws provided should be replaced with appropri- ate fasteners for stucco, brick, concrete, or other types of sidings. Dia. 3.

8)Connect all pipe sections to unit and install into wall:

a)Measure pipe length required and cut to length. Hint: use the cut end of the 6-5/ 8" dia. outer pipe at the vent terminal end.

b)Push the pipe sections completely to- gether, the minimum pipe overlap is

1-1/4". Secure all outer pipe joints by using at least two screws. Locate the screws at the bottom of the pipe so that the screw heads are hidden on the final installation. Apply sealant "Mill-Pac" to inner pipe and high temp silicone seal- ant or "Mill-Pac" to outer pipe on every joint.

8)Slide the decorative wall thimble up to the wall surface being careful not to scratch the paint. See diagram 5.

9)Back outside: Apply sealant to the 4" inner flue and slide the Riser Vent Front into the Backing Plate and fasten with 8 screws.

IMPORTANT:

When connecting the pipe to the Ris- er Vent, apply Mill-Pac to the inner pipe on the Riser Vent Terminal, around the bead. Ensure that the vent pipe is pushed past the bead for a secure fit.

5)If installing termination on a siding covered wall, a vinyl siding standoff or furring strips must be used to ensure that the termination is not recessed into the siding. Dia. 3.

6)Take the Riser Vent terminal and separate the Backing Plate from the Riser Vent Front by removing 8 screws as shown in dia- gram 4.

7)Install the Backing Plate into the wall pene- tration heat shield and attach using 4 screws. Dia. 4.

Hint: Apply sealant to female end.

c)Before connecting the vent pipe to the vent termination, slide the black deco- rative wall thimble cover over the vent pipe, then slide the Wall Penetration Heat Shield (Part # 946-202) over the vent pipe. Dia. 3.

d)Slide the appliance and vent assembly towards the wall carefully inserting the vent pipe into the riser vent terminal assembly. It is important that the vent pipe extends into the Riser Vent Back- ing Plate a sufficient distance so as to result in a minimum pipe overlap of

1-1/4 inches. Secure the connection between the vent pipe and the vent cap by attaching the two sheet metal strips extending from the Riser Vent Backing Plate into the outer wall of the vent pipe.

10)Seal around the outer edge of the Riser Vent Backing Plate.
