INSTALLATION

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 adaptor up through the support box and flashing to proper height as per Dia. 12, local codes or page 11. 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.

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 increase 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.

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 chim- ney 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 at- tached 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

4inch aluminum liner is connected to the adaptor and is passed down the chimney 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 masonry chimney, the chimney must be inspected and thoroughly cleaned by a qualified service person, such as a certified chim- ney sweep or home inspection service.

The direct vent system must not be con- nected to a damaged factory-built or ma- sonry chimney.

For factory built, zero clearance, and ma- sonry chimneys cleanout doors and caps or plugs for cleanout tee fittings and ash dumps shall be secured in place and sealed before installing a Direct Vent sys- tem within the chimney.

If the appliance shuts off during opera- tion, contact a qualified service person to determine if a negative pressure and/or leaky chimney condition exists. Do not operate the appliance until the problem is corrected.

Approved for US Installations Only

The use of an existing chimney as an air intake is not covered under the ANSI Z21.88b-1999, CSA 2.33b-M99 test meth- ods and the resulting ITS/WHI product certification. The code Authority Having Jurisdiction must be consulted prior to proceeding with this installation method.

Converting a Factory Built Metal

Chimney

1)Remove the existing chimney cap.

2)Measure the distance from the top end of the chimney to the bottom of the ceiling support box, add 3" (76mm) to this meas- urement, and cut a section of the 4" flex pipe to that length (the flex should already be extended to its nominal length).

Diagram 1

3)Connect the end of the flex pipe section to the underside of the Top Adaptor using 3 sheet metal screws.
