Warning: Clearances must be sufficient to allow access for maintenance and service.
Initial Installation QUALIFIED INSTALLERS ONLY The framing boards may touch the top, side and back standoffs, but no insulation or other material can be placed between the frame and the standoffs. The gas line, 3⁄8 inch NPT, can be brought to either the right side, the left side, or the bottom of the fireplace. If this set up is inconvenient, the electrical wire and the gas line configuration can be reversed. The location should be chosen so the fireplace must be at least 36 inches (91.

Initial Installation QUALIFIED INSTALLERS ONLY 9. Install the flex pipe assembly through the wall thimble, ensure that this portion of pipe slides through the outside wall far enough to connect onto the vent termination cap. 10. Apply a bead of Mill-Pac Black sealant to the top section of the Ø4” (10 cm) by 5” (12.5 cm) flue collar adaptor previously installed into the fireplace flue outlet. Slide the Ø4” (10 cm) flex vent over the flue collar and secure with three (3) sheet metal screws evenly spaced. 11.
Initial Installation QUALIFIED INSTALLERS ONLY WARNING: Do not mix parts from different vent manufacturers’s systems. EXCEPTION TO WARNING: This product has been evaluated by Intertek for using a Direct Vent GS starting collar in conjunction with Secure Vent, Direct-Temp, and Ameri Vent Direct venting systems. Use of these systems with the Direct Vent GS starting collar is deemed acceptable and does not affect the Intertek WH listing of the appliance.
Initial Installation QUALIFIED INSTALLERS ONLY VENTING: This fireplace has been tested and certified for use with SIMPSON DURAVENT DIRECT VENT TYPE “GS” PIPE FOR GAS STOVES, SECURITY CHIMNEY’S SECURE VENT DIRECT VENT SYSTEM kits, AMERICAN METAL PRODUCTS AMERIVENT DIRECT and DIRECT-TEMP SELKIRK METALBESTOS. A 1” (25 mm) clearance to combustibles must be maintained around any vertical vent pipe.
Initial Installation QUALIFIED INSTALLERS ONLY VENT CONFIGURATIONS AND RESTRICTOR SETTINGS: Figures 33 shows the range of venting options, it shows possible vent configurations if the unit is top vented, for vertical and horizontal terminations, any layout that remains within the shaded area is acceptable. Having the fewest number of elbows is ideal, as they tend to disrupt air movement. Using 45˚ elbows is preferable to using 90˚ elbows. Also, a shorter vent system will perform better than a longer one.
Initial Installation QUALIFIED INSTALLERS ONLY HORIZONTAL TERMINATION: NOTES: 1. Horizontal pipes must not be level. For every 12 inches (305 mm) of horizontal travel (away from the stove), there should be at least 1⁄4 inch (6.4 mm) of vertical travel. Never allow the vent to run downward, as this could cause high temperatures or even present the possibility of a fire. 2. The exterior of the horizontal vent termination must not be blocked or obstructed. 3.
Initial Installation QUALIFIED INSTALLERS ONLY NOTE: For Simpson Duravent only, place a bead of Mil-Pac or Rutland No 78 Stove and Gasket Cement on the outer edge of the inner exhaust pipe (non-flared end). Push the pipe sections together, then twist about 1⁄4 turn, making sure the two sections are fully locked. Wrap all seams with foil ducting tape. Step 4. With the hole now framed, the wall thimble installed, and the pipe extending into the wall, proceed to the outside.
Initial Installation QUALIFIED INSTALLERS ONLY STEP 5. Cut hole in the roof centered on the small hole placed in the roof from Step 2. The hole should be of sufficient size to meet minimum requirements for Clearance to Combustibles, as specified. Continue to assemble lengths of pipe and elbows necessary to reach from the ceiling support box up through the roof line. Galvanized pipe and elbows may be utilized in the attic, as well as above the roof line.
Initial Installation QUALIFIED INSTALLERS ONLY NOTES: (1) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet (914 mm), to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose (see Figure 38). plumber’s tape connected to wall strap (2) When ever possible, use 45° degree elbows instead of 90° degree elbows.
