Anleitung Zusammenfassung
Frame the hole as shown in diagram 9. Note: For best results and optimum performance with each approved venting system, it is highly recommended to apply “Mill-Pac” sealant (supplied) to every inner pipe connection. Failure to do so may result in drafting or performance issues not covered under warranty. Silicone (red RTV) is optional. 4) Assemble the desired lengths of black pipe and elbows necessary to reach from the appliance adapter up though the Round Support Box. Insure that all pipes and elbow connections are in the fully twist-locked position and sealed. Diagram 10: The upper half of the fl ashing is installed under the roofi ng material and not nailed down until the chimney is installed. This allows for small adjustments. Note: If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet, to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose. See diagram 5. Galvanized pipe and elbows may be utilized in the attic as well as above the roofl ine. The galvanized fi nish is desirable above the roofl ine due to its higher corrosion resistance. Continue to add pipe sections through the fl ashing until the height of the vent cap meets the minimum height requirements specifi ed 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. 5) Cut a hole in the roof centred on the small drilled hole placed in the roof in Step 2. The hole should be of suffi cient size to meet the minimum requirements for clearance to combustibles of 1-1/4". Slip the fl ashing under the shingles (shingles should overlap half the fl ashing) as per diagram 10. 6) Continue to assemble pipe lengths. INSTALLATION Diagram 9 INSTALLATION CONVERTING CLASS-A METAL CHIMNEY OR MASONRY CHIMNEY TO DIRECT VENT SYSTEM 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 attached 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 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 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 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 qualifi ed service person, such as a certified chimney sweep or home inspection service. The direct vent system must not be connected to a damaged factory-built or masonry chimney. For factory built, zero clearance, and masonry 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 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 Z21.88b1999, CSA 2.33b-M99 test methods and the resulting ITS/WHI product certifi cation. 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 measurement, 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. Diagram 2. Diagram 2 4) Pass the flex pipe down through the center of the chimney system, an...
