5.Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the roof and fram- ing with roofing nails. Be sure roofing material overlaps the top edge of the flashing as shown in Figure 16, page 12.

There must be a 1" clearance from the vent pipe to combustible materials.

6.Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements described in

Figure 6 on page 7. Note: You must in- crease 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 sec- tion of vent pipe.

Note: If the vent pipe passes through any oc- cupied areas above the first floor, including storage spaces and closets, you must enclose pipe. You may frame and sheetrock the en- closure 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.

Outside Air Flex Installation

Outside air flex installation is required for both horizontal and vertical venting installation. There are 2 outside air flex kits available for

purchase (see Parts List for Venting Kits and Components, page 14).

Construct a 4 1/2" x 4 1/2" framing or opening

on exterior wall (see Figure 19). Install outside

air vent termination in a location that would not eventually be obstructed by bushes, snow or other obstructions. Locate outside air vent

near fireplace to make flex duct installation

easier.

High Altitude Installation

Your DESA direct vent fireplace has been tested and approved for elevations from 0- 2000 feet (USA) and elevations from 0-4500 feet (Canada).

When installing at an elevation above 2000 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 1000 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, check with local authori- ties.
