Waterford Appliances T25-LP Cathedral Ceilings, Support Extensions Round Rdse or Square Sqse

INSTALLATION

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

Support Extensions - Round (RDSE) or Square (SQSE)

Steep pitched cathedral ceilings may require the use of a support extension. This piece fits down inside the support and can be adjusted to in- crease the support's length by up to 22". The extension is attached to the support using the eight metal screws provided. Be sure there is at least a 2 inch overlap where the extension joins the support.

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 location 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.

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"

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

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 shin- gles.

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 page 16. 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.

CONVERTING A

CLASS-A METAL

CHIMNEY OR

MASONRY CHIMNEY TO A DIRECT VENT SYSTEM

General

There are two different types of direct vent conversion systems listed below. Follow the appropriate directions for your installation.

A)Through an existing factory built metal chimney going through the ceiling: A typical conversion of this type is shown in diagram

1.The concept of direct vent conversion is to connect an adaptor to an Underwriters Laboratories (UL) listed 4 inch diameter aluminum flex pipe which is then passed down through the center of the existing metal chimney system. Three sizes of Top Adaptors are available from Simpson Dura- Vent. The Retro Connector (909B) is at- tached to the bottom of the flex pipe. The Top Adaptor and the Retro Connector are attached to the existing chimney with sheet metal screws. The appliance is then con- nected to the chimney with appropriate black direct vent pipe and an adjustable length section.

B)Through the wall of an existing masonry chimney: A typical conversion of an exist- ing masonry chimney is shown in Diagram

6.A Top Adaptor (985K) and Flashing are used at the top of the masonry chimney. The 4 inch aluminum liner is connected to the adaptor and is passed down the chim- ney and out through the masonry wall and attached to the Retro Connector (909B). The Retro Connector is attached to the masonry wall and then connected to the direct vent pipe leading to the appliance.

Prior to installation and connection of the vent system to a factory-built or mason- ry chimney, the chimney must be in- spected and thoroughly cleaned by a qualified service person, such as a cer- tified chimney sweep or home inspec- tion service.
