Below Grade Snorkel Installation

INSTALLATION

Diagram 2b

NOTE: For Snorkel terminations in ABOVE gradeinstallations,follownationalor local code requirements.

If the Snorkel Termination must be installed below grade, i.e. basement application, proper drainage must be provided to prevent water from enter- ing the Snorkel Termination. Refer to Dura-Vent Installation instructions for details.. 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 together, 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 ﬁ nal installation.

NOTE: For best results and optimum performance with each approved venting system, it is highly recom- mended to apply “Mill-Pac” sealant (supplied) to every inner pipe con- nection. Failure to do so may result in drafting or performance issues not coveredunderwarranty.Silicone(red RTV) is optional.

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 Backing 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. Use two aluminum screws provided to connect the strips to the pipe section. Bend any remaining portion of the sheet metalstripbacktowardstheventcapand cut off any excess, it will be concealed by the decorative wall thimble cover. See diagram 5.

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 ﬂ ue and slide the Riser Vent Front into the Backing Plate and fasten with 8 screws.

IMPORTANT:

When connecting the pipe to the Riser Vent, apply Mill-Pac to the inner pipe on theRiserVentTerminal,aroundthebead. 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 diagram 4.

7)Install the Backing Plate into the wall penetration 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.

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