INSTALLATION
Diagram 5
The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.
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.
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 suffi cient distance so as to result in a minimum pipe overlap of
UNIT INSTALLATION WITH VERTICAL TERMINATION 
1)Maintain the 
(air spaces) to combustibles when passing through ceilings, walls, roofs, enclosures,
attic rafter, or other nearby combustible surfaces. Do not pack air spaces with insulation. Check the "Venting" section 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 fl ue 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 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 a p p l i a n c e or to offset, as shown in
Diagram 2 to
avoid cutting load bearing members.
4)Assemble the desired lengths of pipe and elbows. Ensure that all pipes and elbow connections are in the fully
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 suffi cient size to meet the minimum requirements for clearance to combustibles of
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, to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose (Diagram 2).
Galvanized pipe is desirable above the roofl ine due to its higher corrosion resistance. Continue to add pipe sections through the
flashing until the height of the vent cap meets the minimum height requirements specifi ed in Diagram 5 or local codes. Note that for

9) Install wall thimble in the center of the 10" square and attach with wood screws (Diagram 7).

Note: Apply sealant
3)A Firestop spacer must be installed in the
floor or ceiling of every level. To install the Firestop spacer in a fl at ceiling or wall, cut a 10 inch square hole. Frame the hole as shown in Diagram 3 and install the fi restop.
