INSTALLATIONS

Install the vent system according to the manufacturer's instructions included with the components.

gram 1. Push the pipe sections com- pletely together, then twist-lock one section clockwise approximately one- quarter turn, until the two sections are fully locked. The female locking lugs will not be visible from the outside, on the Black Pipe or fittings. They may be located by examining the inside of the female ends.

1)Set the unit in its desired location. Check to determine if wall studs or roof rafters are in the way when the venting system is at- tached. If this is the case, you may want to adjust the location of the unit. Rough in the gas.

2)Direct Vent pipe and fittings are designed with special twist-lock connections to con- nect the venting system to the appliance flue outlet. A twist-lock appliance adaptor is an available option that must be used in con- junction with the Simpson Dura-Vent Direct Vent GS system.

3)Put a bead of silicone inside the outer section of the adapter and a bead of Mill Pac on the inner collar. Slip the adapter over the exist- ing inner and outer flue collar and fasten to the outer collar only with the 3 supplied screws (drilling pilot holes will make this easier). Level the fireplace and fasten it to the framing using nails or screws through the nailing strips.

4)Assemble the desired combination of pipe and elbows to the appliance adaptor and twist-lock for a solid connection.

Note:

a)Twist-lock procedure: Four indentations, located on the female ends of pipes and fittings, are designed to slide straight onto the male ends of adjacent pipes and fittings, by orienting the four pipe inden- tations so they match and slide in to the four entry slots on the male ends, Dia-

Diagram 1

Note: Apply sealant "Mill-Pac" to inner pipe and high temperature sili- cone sealant to outer pipe on eve- ry twist-lock joint.

b)Horizontal runs of vent must be sup- ported every three feet. Wall straps are available for this purpose.

5)Mark the wall for a 10" x 10" square hole. The center of the square hole should line up with the centerline of the horizontal pipe. Cut and frame the 10 inch square hole in the exterior wall where the vent will be termi- nated. If the wall being penetrated is con- structed of non-combustible material, i.e. masonry block or concrete, a 7"(178mm) dia. (7-1/2"(191mm) dia. for flex) hole is acceptable.

Note: With Dura-Vent, the minimum height is achieved by installing a 45o elbow di- rectly to the flue adaptor.

Diagram 2

Note:

a)The horizontal run of vent must be level, or have a 1/4 inch rise for every 1 foot of run towards the termination. Never allow the vent to run downward. This could cause high temperatures and may present the possibility of a fire.

b)The location of the horizontal vent ter- mination on an exterior wall must meet all local and national building codes, and must not be blocked or obstructed. For External Vent Terminal Locations, see diagram on page 12.

6)The arrow on the vent cap should be pointing up. Insure that the 1-1/2" clear- ances to combustible materials are main- tained (Diagram 3 on page 16). Install the termination cap.

The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.

Note: If installing termination on a siding covered wall, a vinyl siding stand- off or furring strips must be used
