UNIT INSTALLATION WITH HORIZONTAL TERMINATION
(Rigid Vent Systems)
Atopclearanceof3"(76mm)andside&bottom clearance of 2"(51mm) must be maintained; except when passing through a wall, ceil- ing, or at the termination where the use of a firestop or wall thimble reduces the required clearance to
Install the vent system according to the manufacturer's instructions included with the components.
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 attached. If this is the case, you may want to adjust the location of the unit. Rough in the gas preferably on the right side of the unit and the electrical (junction block is on the left side) on the left.
2)Direct Vent pipe and fittings are designed with special
3)In conjunction with the Simpson Direct Vent Pro system, install the adaptor after the unit is set in its desired location. Put a bead of high temperature silicone inside the outer section of the adapter and a bead of Mill Pack on the inner collar. Slip the adapter over the existing inner and outer flue collar. Fasten to the outer collar only with the 3 supplied screws (drilling pilot holes will make this easier).
4)Level the fireplace and fasten it to the framing using nails or screws through the top and side nailing strips.
5)Assemble the desired combination of pipe and elbows to the appliance adaptor and
Note: For best results and optimum performance with each approved venting system, it is highly recommended to apply
Horizontal runs of vent must be supported every 3 feet (0.9meter). Wall straps are available for this purpose.
6)Mark the wall for a 11" x 11" (279mm x 279mm) square hole. The center of the square hole should line up with the center- line of the horizontal pipe. Cut and frame the 11 inch (279mm) square hole in the exterior wall where the vent will be terminated. See diagram 2 for center line requirements.
If the wall being penetrated is constructed of

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 termination on an exterior wall must meet all local and national building codes, and must not be blocked or obstructed. See "Exterior Vent Termination Locations" section for more details.
7)Ensure that the pipe clearances to combustible materials are maintained (Diagram 5). Install the termination cap.
Note: If installing termination on a vinyl siding covered wall, a vinyl siding standoff or furring strips must be used to ensure that the termination is not recessed into the siding.

The four wood screws provided should be re- placed with appropriate fasteners for stucco, brick, concrete, or other types of sidings.
8)Before connecting the horizontal run of vent pipe to the vent termination, slide the Wall Thimble over the vent pipe. The wall thimble is required for all horizontal terminations.
9)Slide the appliance and vent assembly towards the wall carefully inserting the vent pipe into the vent cap assembly. It is important that the vent pipe extends into the vent cap sufficient distance so as to result in a minimum pipe overlap of
10)Install wall thimble in the center of the 11" (279mm) square and attach with wood screws (Diagram 7).
