INSTALLATION

6)The arrow on the vent cap should be pointing up. Insure that the 1-1/4"(32mm) clearances to combustible materials are maintained (Diagram 5). Install the termination cap.

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.

9) Install wall thimble in the center of the 10" (254mm) square and attach with wood screws (Diagram 6).

Diagram 3

Diagram 5

The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.

7)Before connecting the horizontal run of vent pipe to the vent termination, slide the Wall Thimble (Part # 942) over the vent pipe.

8)Slide the appliance and vent assembly towards the wall carefully inserting the vent pipe into the vent cap assembly. It is important that the vent pipe extends into the vent cap sufficient distance so as to result in a minimum pipe overlap of 1-1/4 inches (32mm).Secure theconnectionbetweenthe 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 section. See Diagram 6.

3)A Firestop spacer must be installed in the fl oor or ceiling of every level. To install the Firestop spacer in a fl at ceiling or wall, cut a 10 inch (254mm) square hole. Frame the hole as shown in Diagram 3 and install the fi restop.

4)Assemble the desired lengths of pipe and elbows. Ensure that all pipes and elbow connections are in the fully twist-locked position and sealed.

NOTE: For best results and optimum performance with each approved venting system, it is highly recommended to apply “Mill-Pac” sealant (supplied) to every in- ner pipe connection. Failure to do so may result in drafting or performance issues not covered under warranty. Silicone (red RTV) is optional.

5)Cut a hole in the roof centered on the small drilled hole placed in the roof in Step 2. The hole should be of sufficient size to meet the minimum requirements for clearance to combustibles of 1-1/4"(32mm). Slip the fl ashing under the shingles (shingles should overlap half the fl ashing) as per Diagram 4.

Diagram 4: The upper half of the fl ashing is installed under the roofi ng material and not nailed down until the chimney is installed.

This allows for small adjustments.

6)Continue to assemble pipe lengths.

Note: If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet (0.9 meter), to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose

(Diagram 2).

Note that for steep roof pitches, the vertical height must be increased.
