Vent System

INSTALLATION

CONVERTING CLASS-A METAL CHIMNEY OR MASONRY CHIMNEY TO DIRECT

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 ﬂ ex pipe which is then passed down through the center of the existing metal chimney system. Three sizes of Top Adap- tors are available from Simpson Dura-Vent. The Retro Connector (909B) is attached to the bottom of the ﬂ ex pipe. The Top Adaptor and the Retro Connector are attached to the existing chimney with sheet metal screws. The appliance is then connected 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 existing masonry chimney is shown in Diagram 6. A TopAdaptor (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 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 chimney sweep or home inspection service.

The direct vent system must not be con- nectedtoadamagedfactory-builtormasonry 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 operation, contact a qualiﬁed service person to de- termine 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 theANSI Z21.88b- 1999, CSA 2.33b-M99 test methods and the resulting ITS/WHI product certiﬁcation. The code Authority Having Jurisdiction must be consulted prior to proceeding with this instal- lation 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 measurement, and cut a section of the 4" ﬂ ex pipe to that length (the ﬂ ex should already be extended to its nominal length).

Diagram 1

3)Connect the end of the ﬂ ex pipe section to the underside of the Top Adaptor using 3 sheet metal screws. Diagram 2.

4)Pass the ﬂ ex pipe down through the center of the chimney system, and center the adap- tor on the top of the chimney pipe. Drill four 1/8" diameter holes through the adaptor 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. (Diagram 3 and 4).

5)Pull the ﬂ ex pipe down through the ceiling support box, until it protrudes approximately 3"(76mm).ConnecttheﬂexpipetotheRetro 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 ﬂ ex pipe back up into the ceiling supportbox,centertheRetroConnector,and attach it to the support box, or decorative sleeve for double wall solid packed pipe, with the sheet metal screws (supplied). The holes in the Retro Connector are pre- punched. Diagram 5.

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.
