Converting a Masonry Chimney

INSTALLATION

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 system 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.

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

4)Pass the flex pipe down through the center of the chimney system, and center the adaptor on the top of the chimney pipe. Drill four 1/8" diameter holes through the adap- tor and into the chimney top. Insure that you are in fact, drilling into the metal on the chimney. Twist-lock the Termination Cap (Part# 980 or 991) onto the Adaptor. (Dia- gram 3 and 4).

7)The connection between the appliance and the Retro Connector may be completed with sections of black direct vent pipe, together with an adjustable length.

Important: The existing masonry flue opening needs to have an area of at least a 36 sq. in. to insure proper intake/ex- haust flow.

1)Before cutting any holes, assemble the desired sections of black direct vent pipe to determine the center of the masonry pene- tration.

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).

5)Pull the flex pipe down through the ceiling support box, until it protrudes approximate- ly 3" (76mm). Connect the flex pipe to the Retro Connector by slipping it into the

4-3/4" diameter sleeve on the top side of the Connector. Use 3 sheet metal screws to assemble these two parts.

6)Push the flex pipe back up into the ceiling support box, center the Retro Connector, and attach it to the support box, or decora- tive sleeve for double wall solid packed pipe, with the sheet metal screws (sup- plied). The holes in the Retro Connector are pre-punched. Diagram 5.

2)Once the center point of the penetration has been determined, cut a 6" (152mm) dia. hole in the masonry. Be careful, if the hole is too large, the Retro Connector might not mount properly, and if the hole is too small, then the appliance might starve for intake air. If there is a frame wall in front of the masonry wall, cut and frame a 10" (254mm) clear square opening in the wall (centered around the 6" (152mm) masonry opening). IF there is sheet rock only (no studs) in front of the masonry, the 10" (254mm) clear opening is still needed, but does not need to be framed. This allows the Retro Connector to mount directly on the masonry and provide clear- ance to the combustibles. Diagram 11.

3)Secure the Flashing (Part # 705C) to the top of the masonry chimney using a bead of non-hardening sealant-adhesive. If the Flashing is larger than the top of the chim- ney, then cut and fold flashing as needed to fit chimney. Diagram 7.
