INSTALLATION
DURA-VENT VERTICAL
TERMINATION
1) Maintain the 1-1/4" clear- ances (air spaces) to com- bustibles when passing through ceilings, walls, roofs, enclosures, attic raft- er, or other nearby com- bustible surfaces. Do not pack air spaces with insu- lation. Check page 9 for the maximum vertical rise of the venting system and the maximum horizontal offset limitations.
2) Set the gas appliance in its desired location. Drop a plumb bob down from the ceiling to the position of the appliance flue exit, and mark the location where the vent will penetrate the ceiling. Drill a small hole at his point. Next, drop a
plumb bob from the roof to Diagram 8 the hole previously drilled in the ceiling, and mark the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters or other framing will obstruct the venting system. You may wish to relocate the appliance or to offset, as shown in diagram 9 to avoid cutting load bearing members.

3) To install the Round Support Box/Wall Thim- ble in a flat ceiling, cut a 10 inch square hole in the ceiling centred on the hole drilled in Step 2. Frame the hole as shown in diagram 10.

Below Grade Installation
If the Snorkel Termination must be installed below grade, i.e. basement application, proper drainage must be provided to prevent water from entering the Snorkel Termination. Refer to Dia. 4. Do not attempt to enclose the Snorkel within the wall, or any other type of enclosure.

4)If installing the vent termination to a wall with vinyl siding, the Vinyl Siding Standoff must be used. Attach the Vinyl Siding Standoff to the Horizontal Vent Termina- tion, but first run a bead of non-hardening mastic around its outside edges, so as to make a seal between vent cap and the standoff. Install the Vinyl Siding Standoff (Part # 950) between the vent cap and the exterior wall and attach with the four wood screws provided. Seal around the Vinyl
Siding Standoff on all four sides. Diagram
5.The arrow on the vent cap should be pointing up. Insure that the 1-1/4" clearances to combustible materials are maintained. See diagram 5.
Note: 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. The four wood screws provided should be replaced with appropriate fas- teners for stucco, brick, concrete, or other types of sidings.
5)Before connecting the horizontal run of vent pipe to the vent termination, slide the black decorative wall thimble cover over the vent pipe, then slide the Wall Thimble (Part # 942) over the vent pipe.
6)Slide the appliance and vent assembly to- wards the wall carefully inserting the vent pipe into the vent cap assembly. It is impor- tant that the vent pipe extends into the vent cap 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 vent cap assembly into the outer wall of the vent pipe. Use the two sheet metal screws provided to connect the strips to the pipe. Bend any remaining portion of the sheet metal strip back towards the vent cap, so it will be concealed by the decorative wall thimble cover. See diagram 6.

7)Install the Wall Thimble in the center of the 10" square and attach with wood screws.
8)Slide the decorative wall thimble up to the wall surface being careful not to scratch the paint and attach with screws provided. Apply decorative brass or chrome trim if desired. See diagram 7.
