INSTALLATION

roofline. The galvanized finish is desirable above the roofline due to its higher corro- sion resistance.

Continue to add pipe sections through the flashing until the height of the vent cap meets the minimum height requirements specified in diagram 11 or local codes. Note that for steep roof pitches, the vertical height must be increased. A poor draft, or down drafting can result from high wind conditions near big trees or adjoining roof lines, in these cases, increasing the vent height may solve the problem.

7)Ensure vent is vertical and secure the base of the flashing to the roof with roofing rails, slide storm collar over the pipe section and seal with a mastic.

8)Install the vertical termination cap by twist locking it.

Notes:

a)For multistorey vertical installations, a Ceiling Fire stop (Part # 963) is required at the second floor, and any subse- quent floor. Diagram 12. The opening should be framed to 10 " x 10" inside dimensions, in the same manner as shown in diagram 9.

b)Any occupied areas above the first floor, including closets and storage spaces, through which the vertical vent passes, must be enclosed.

CATHEDRAL CEILINGS

Round Support (RDS) &

Square Support (SQS)

If your home has a cathedral ceiling (no attic space between the ceiling and the roof), install the chimney and support as follows.

1)Situate the chimney in a convenient loca- tion as near as possible to the appliance outlet. Cut and frame a hole in the roof for the support. The sides of this hole must be vertical with 1 1/4" clearance.

2)Place the support in the opening. Lower it to the correct height as determined by the table and diagram below.

Slope		"X"

0/12	- 2/12	4"

2/12	- 7/12	5-1/2"

7/12	- 12/12	6-3/4"

12/12	- 24/12	7-1/2"

24/12+		12-1/2"

Using a level, make sure the support is vertical. If the support extends above the roof, cut it flush with the top of the roof. Nail the support to the frame opening using (8) 3" spiral nails or #8 x 1-1/2" screws.

Note: If you are using a 6" square sup- port you may find it difficult to screw it in place because it is fairly small inside.

Simpson Dura-Vent has provided angle brackets with this support which can be screwed to the outside of the support box and nailed to surrounding framing as re- quired. Use a minimum of four #8 x 1/2" screws per bracket. In some cases these brackets may need to be trimmed (e.g.: to fit under a flashing). Place the Finish Collar around the support and fasten it to the ceiling using the screws provided.

3)Use appropriate roof flashing. Place the flashing under the upper shingles and on top of the lower shingles approximately half of the flashing should be under the shingles.

4)Assemble the desired lengths of Black Pipe and Elbows necessary to reach from the appliance adapter up through the support box and flashing to proper height as per Dia. 12, local codes or pages 12 to 13. Ensure that all pipe and elbow connections are in their fully twist lock position.

5)Ensure vent is vertical and secure flashing to the roof with roofing nails. Slide the storm collar over the pipe section and seal with a mastic.

6)Twist lock the vent cap on to the last section.
