DuraTech Premium ll-fuel himney Planning Your Installation 3 FT. MIN. OVE ROOF PENETRTION Figure 1 2 FT. MIN. OVE HIGHEST POINT OF THE UILDING WITHIN 10 FT. 10 12 MINIMUM HIMNEY HEIGHT REQUIREMENT 6 The following recommendations are a general guideline to assist in the layout and selection of the chimney components needed for your installation. lways follow DuraVent Installation instructions before installing your chimney system (enclosed with the cap or support box). Installation instructions can be viewed online at www.duravent.com under support > literature. The diameter of the chimney should match the outlet size of the appliance. n improperly sized chimney results in poor draft and excessive creosote formation. Measure the diameter of the appliance flue outlet. Select the chimney and either DVL or Duralack connector stovepipe with the same size diameter as the appliance flue outlet. Determine if the installation is a through-the-roof installation or a through-the-wall installation. through-the-wall installation will require additional components (Wall Thimble, Tee/ap, Tee Support, and Wall Straps). Install the chimney in the interior of the structure whenever possible. cold exterior chimney will produce less draft and will generate more creosote. If possible avoid offsets that serve to restrict the natural draft. straight vertical installation is more efficient and less likely to develop creosote. If an offset is required to avoid rafters or other obstructions, measure the horizontal distance required and the vertical height available. 15, 30 and 45 elbows are available. (Note: 45 elbows are only allowed in anada. The maximum angle allowed in the U.S. is 30.) maximum of two offsets (four elbows) in a single installation are permitted. t least one Elbow Support is required for each offset. Determine the minimum chimney height above the roof line. uilding codes require a minimum of 3 above the roof penetration and at least 2 higher than any portion of a building within 10. See Figure 1. The termination cap is installed above that point. If chimney is more than 5 above the roof penetration a Roof race is required. Measure the roof pitch. For example, a 6/12 pitch has a vertical rise of 6 over a horizontal distance of 12. Select the appropriate flashing. Determine the total length of chimney and stovepipe required for the installation. To calculate the installed length of 6-8 DuraTech Premium chimney pipe, subtract 1 per joint. Subtract 1 ¼ per joint of Duralack stovepipe. Subtract 1 1/4 per joint of DVL stovepipe. Minimum chimney height, at sea level, of straight vertical chimney, is 10 to 15 above the appliance outlet. Higher elevations, or the use of elbows or a tee, will require approximately 30% to 60% more height to provide for an adequate draft. e fire safe. Maintain at least 2 clearance to combustibles. Follow local building codes and have your chimney inspected by a certified professional. 80 DuraVent www.duravent.com
