Below Grade Installation

INSTALLATION

UNIT INSTALLATION WITH HORIZONTAL TERMINATION

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 ﬁ ttings are designed

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

5)Mark the wall for a 11" x 11" 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 terminated. If the wall being penetrated is constructedofnon-combustiblematerial,i.e. masonry block or concrete, a 8" dia. hole is acceptable.

Note: With Dura-Vent, the minimum height is achieved by installing a 90o elbow directly to the ﬂue adaptor.

with special twist-lock connections to

connect the venting system to the appliance

ﬂ ue outlet. A twist-lock appliance adaptor

is an available option that must be used in

conjunction 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 existing inner and outer ﬂ ue collar

and fasten to the outer collar only with the

3 supplied screws (drilling pilot holes will

make this easier). Level the ﬁ replace 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-lockprocedure:Fourindentations, located on the female ends of pipes and ﬁ ttings, are designed to slide straight onto the male ends of adjacent pipes and ﬁ ttings, by orienting the four pipe indentations so they match and slide in to the four entry slots on the male ends, Diagram 1. Push the pipe sections completely 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 ﬁ ttings. They may be located by examining the inside of the female ends.

Diagram 1

Note: Apply sealant "Mill-Pac" to inner pipe and high temperature silicone sealant to outer pipe on every twist- lock joint.

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 ﬁ re.

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. For External Vent Terminal Locations, see diagram from the "Exterion Vent Termination Locations" section.

c)Snorkel Terminations:

For installations requiring a vertical rise on the exterior of the building, 14-inch and36-inchtallSnorkelTerminations are available. Follow the same installation procedures as used for standard Horizontal Termination. NEVER install the snorkel upside down.

Diagram 3

*Diagam 3 & 4: As speciﬁed in CGA B149 InstallationCode.Localcodesorregulations may require different clearances.

If the Snorkel Termination must be installed below grade, i.e. basement application, proper drainage must be provided to prevent water from entering the Snorkel Termination. Refer to Diagram 4. Do not attempt to enclose the Snorkel within the wall, or any other type of enclosure.

Diagram 4

NOTE: For Snorkel terminations in ABOVE grade installations, follow national or local code requirements.

6)The arrow on the vent cap should be pointing up. Insure that the 1-1/2" clearances to combustible materials are maintained (Diagram 4). Install the termination cap.
