Venting installation

CSDV Series Direct Vent Gas Stove

Drop a plumb line from the inside of the roof to the locat- ing hole in the ceiling. Mark the center point where the vent will penetrate the roof. Drill a small locating hole at this point.

FLAT CEILING INSTALLATION

1.Cut a 9Z\x" (241 mm) square hole in the ceiling using the locating hole as a center point The opening should be framed to 9Z\x" x 9Z\x" (241 x 241 mm) inside dimensions as shown in Figure 26 using framing lumber the same size as the ceiling joist. If the area above the ceiling is an insulated ceiling or a room, nail firestop from the top side. This prevents loose insulation from falling into the required clearance space. Figure 23. Otherwise, install firestop below the framed hole. The firestop should be installed with no less than three nails per side. Figure 26

2.Assemble the desired lengths of pipe and elbows nec- essary to reach from the burner system flue up through the firestop. Be sure pipe and elbow connections are fully twist-locked. Page 15, Figure 16

3.Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before cut- ting hole in roof). The 9Z\x" x 9Z\x" (241 x 241 mm) hole must be measured on the horizontal. Actual length may be larger depending on the pitch of the roof. There must be a 1" minimum clearance from the vent pipe to combustible materials. Frame the opening as shown in on Page 16, Figure 17.

4.Connect a section of pipe and extend up through the hole.

NOTE: If an offset is needed to avoid obstructions, you must support the vent pipe every three (3) feet. Use wall straps for this purpose. Page 18, Figure 24. Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air.

5.Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the roof and framing with roofing nails. Be sure roofing material overlaps the top edge of the flashing as shown in Page 18, Figure 24. There must be a 1" clearance from the vent pipe to combustible materials.

6.Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements.

NOTE: You must increase vent height for steep roof pitches. Nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors may cause poor draft or down-drafting in high winds. Increasing the vent height may solve this problem.

NOTE: If the vent pipe passes through any occupied areas above the first floor, including storage spaces and closets, you must enclose pipe. You may frame and sheetrock the enclosure with standard construction material. Make sure to meet the minimum allowable clearances to combustibles. Do not fill any of the required air spaces with insulation.

CATHEDRAL CEILING INSTALLATION

IMPORTANT: Review all information on previous page before planning this installation. Cathedral ceiling installations can be very tricky.

1.Remove shingles or other roof covering as necessary to cut the rectangular hole for the support box. Mark the outline of the cathedral ceiling support box on the roof sheathing using the locating hole as a center point.

2.Cut the hole 1/8" larger than the support box outline. Figure 27.
