• Use 4” pipe if you have more than 15 feet of equivalent vent length. • Horizontal runs shall not exceed 10 feet of EVL. • It is recommended that vertical runs be a minimum of 8 feet. • To calculate EVL, use the following conversions: 90. elbow or “T” = 5 equivalent feet 45. elbow = 3 equivalent feet Horizontal Pipe Run = 1 equivalent foot per actual foot Vertical Pipe Run = 0.5 equivalent foot per actual foot NOTE: At altitudes above 3,000 feet, we suggest the use of 4” diameter vent at an EVL of 7 feet or more. FREESTANDING INSTALLATIONS A. ASSEMBLING PEDESTAL OR LEG SET If using a pedestal, follow the instructions inside the Breckwell P22 Pedestal Set Part # A-22-P (refer to figure 8). If using cast legs, follow the instructions inside the Breckwell P22 Leg Set Part # A-CGL-22 or # A-CL-22. Legs are installed by using the four bolts provided in the kit into the four holes under the stove at each corner, thread on nuts from the top and tighten. Make sure to save the hole plugs. NOTE: If converting from legs to pedestal the hole plugs must be installed in the unused holes. B. HORIZONTALLY THROUGH WALL (refer to Figure 9) NOTE: Follow L-Vent chimney manufacturer’s instructions. 1. Position stove, adhering to clearances shown in Figures 1 & 2. 2. Locate position of hole in wall; directly behind stove exhaust vent (refer to figure 5). 3. Always maintain 3” clearance from combustible materials. 4. Install L-Vent wall thimble per L-Vent manufacturer’s instructions. 5. Attach enough piping to penetrate and extend at least 6” beyond exterior walls. An 8-foot vertical pipe run is suggested where possible to reduce the possibility of smoke spillage in the event of a loss of negative pressure. 6. Attach cap and seal outside wall thimbles with non-hardening waterproof mastic. 7. Termination should not be located so that hot exhaust gases can ignite trees, shrubs, or grasses or be a hazard to children. Exhaust gases can reach temperatures of 500.F and cause serious burns if touched. FIGURE 8 FIGURE 9 Locate terminations: a) not less than 3 feet above any forced air inlet located within 10 feet; b) not less than 4 feet below or horizontally from, or one foot above, any door, window or gravity air inlet into any building; c) not less than two feet from an adjacent building and not less than 7 feet above grade when located adjacent to a public walkway. Mobile home installations must use a spark arrester. INSTALLATION8 INSTALLATION8 C. VERTICALLY WITH NEW CHIMNEY SYSTEM (Refer to Figure 10) NOTE: Follow L-Vent chimney manufacturer’s instructions. OPTION: To achieve a center vertical installation a 45. elbow and a clean-out tee can be used to offset the pipe from the exhaust outlet to the rear center of the stove. OPTION: Install L-Vent elbow in place of clean-out tee. Locate stove. Drop plumb bob to center of tee outlet, mark point on ceiling. Install ceiling support and L-Vent pipe per L-Vent manufacturer’s instructions. 1. Always maintain 3” clearance from combustible materials. When passing through additional floors or ceilings, always install firestop spacer. 2. After lining up for hole in roof, cut either around or square hole in roof, always 3” larger all the way around pipe. Install upper edge and sides of flashing under roofing materials, nail to the roof along upper edge. Do not nail lower edge. Seal nail heads with non-hardening waterproof mastic. 3. Apply non-hardening, waterproof mastic where the storm collar will meet the vent and flashing. Slide storm collar down until it sits on the flashing. Seal and install cap. Mobile home installations must use a spark arrester. D. VERTICALLY INTO EXISTING CHIMNEY SYSTEM Adapters are available to adapt from 3” L-Vent to 6” or 8” Class-A chimney. (Figure 11a) As an alternative, 3” or 4” L-Vent can be run inside existing chimney to termination. (Figure 11b) This is the preferred method. Follow guidelines for equivalent vent length. FIGURE 11b FIGURE 10 FIGURE 11a INSTALLATION 9 INSTALLATION 9 E. VERTICALLY INTO EXISTING MASONRY FIREPLACE NOTE: Follow L-Vent chimney manufacturer’s instructions. 1. Have the masonry chimney inspected by a qualified chimney sweep or installer to determine its structural condition. 2. You will need a pipe length equal to the chimney height from the hearth. If outside combustion air is to be used, you will need a pipe length equal to the chimney height plus 18 inches. 3. Install a blanking plate and the chimney pipe, and if used the outside air pipe, as shown in Figure 12. 4. Attach the DuraVent adapter, a section of pipe and clean out tee, making sure the clean out tee is centered in the chimney flue area. Use RTV, metallic tape, and a minimum of three self-taping screws at all joint connections to ensure a tight seal. 5. Position the stove, adhering to the clearances in Figures 1 & 2. 6. Measure and build chimney top plate. Cut out holes for chimney pipe, and if used the outside air pipe. Install and seal with non-hardening mastic to prevent...
