Secure the base of the flashing to the roof and framing with roofing nails. Be sure roofing material overlaps the top edge of the flashing as shown in Figure 19. There must be a 1" clearance from the vent pipe to combustible materials. Roof Flashing Wall Strap 45° Elbow If area above is not a room, install firestop below framed hole. If area above is a room or insulated area, install firestop above framed hole. Ceiling Firestop Figure 19 - Offset with Wall Strap and 45° Elbows Figure 20 - Installing Firestop 6. Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements described in Figure 7 on page 7. Note: You must increase vent height for steep roof pitches. Nearby trees, adjoining rooflines, steep pitched roofs and other similar factors may cause poor draft or down-drafting in high winds. Increasing the vent height may solve this problem. 7. Twist-lock the vent cap onto the last section of vent pipe. Note: If the vent pipe passes through any occupied areas above the first floor, including storage spaces and closets, you must enclose pipe. You may frame and sheetrock the enclosure with standard construction material. Make sure and meet the minimum allowable clearances to combustibles. Do not fill any of the required air spaces with insulation. Vertical Termination Configurations Figures 21 through 24 show four different configurations for vertical termination.

When installing this fireplace at an elevation above 2,000 feet (in the USA), you may need to decrease the input rating by changing the existing burner orifice to a smaller size. Reduce input 4% for each 1,000 feet above sea level. Check with your local gas company for proper orifice size identification. When installing this fireplace at an elevation above 4500 feet (in Canada), check with local authorities. Consult your local gas company to help determine the proper orifice for your location.
