PLANNING YOUR INSTALLATION

There are two basic types of Direct Vent System installations. The two types of installations are:

Vertical Termination Horizontal Termination

When planning your installation, it will be necessary to select the proper length of vent pipe for your particular requirements. It

is important to note when passing through a wall, the maximum allowable wall thickness is 10-inches (254mm), 1 ½ inches

clearance to combustibles must be maintained. Select the amount of vertical rise desired for “vertical-to-horizontal” type

installations. To determine the length of vent pipe required for vertical installations, measure the distance from the appliance

flue outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow for sufficient vent

height above the roofline. For two story applications, A firestop is required at each floor level. If an offset is needed in the attic,

additional pipe and elbows will be required. To connect the venting system to the appliance flue outlet, a twist-lock adapter is

built into the appliance at the factory.

HORIZONTAL INSTALLATION

STEP 1. Set the appliance in the 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 appliance.

STEP 2. Direct vent pipe and fittings are designed with special twist-lock connections. Assemble the desired combination of

black pipe and elbows to the appliance adapter with pipe seams oriented towards the wall or floor, as much out of

view as possible.

Place a bead of Mil-Pac on the outer edge of the inner exhaust pipe (non-flared end). Place a bead of high temperature

silicone on the male edge of the outer pipe. 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 black pipe. They may be located by examining the inside of the female ends as shown in FIG-10.

NOTE:

(1) Twist-lock procedure: four indentations, located on the female

end of the pipes and fittings, are designed to slide straight onto

the male ends of adjacent pipes and fittings, by orienting the

four pipe indentations so they match and slide into the four

entry slots on the male end.

(2) Horizontal runs of vent pipe must be supported every three

feet. Wall straps are available for this purpose.

FIG. 10

FIG.10

STEP 3.With the pipe attached to the stove into the correct location, mark the wall for a 10 inch x 10 inch square hole. The

center of the square hole should match the centerline of the horizontal pipe. Cut and frame the 10-inch x 10-inch

hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of non-

combustible material i.e. masonry or concrete, a 7-inch hole is acceptable.

STEP 4. Position the horizontal vent termination in the center of the 10-inch square hole, and attach to the exterior wall with

the four screws provided. Before attaching the Vent Termination to the exterior wall, run a bead of non-hardening

mastic around the edges, so as to make a seal between the termination and the wall. The arrow on the vent

termination should be pointing up, insure that the proper clearances to combustible materials are maintained.

STEP 5. Before connecting the horizontal run of the vent pipe to the vent termination, slide the black decorative wall thimble

cover over the vent pipe.

STEP 6. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the cap assembly. It is

important that the vent pipe extend into the vent cap a sufficient distance with a minimum of 1 ¼inch overlap. Secure

the connection between the vent cap pipe and the vent cap by attaching the two sheet metal straps extending from

the vent cap assembly into the outer wall of the vent pipe. Use the two sheet metal screws provided to connect the

straps to the vent pipe. Bend any remaining portion of the sheet metal straps back towards the vent cap, so the

decorative wall thimble FIG-13 will conceal it.

STEP 7. Slide the decorative wall thimble up to the wall surface and attach with the screws provided. Apply decorative brass

or chrome trim if desired. FIG-14.

FIG. 11 FIG. 12

FIG-13 FIG-14

NOTES:(1) The four wood screws provided should be replaced with the appropriate fasteners for stucco, brick, concrete, or

other types of siding.

(2) For buildings with vinyl siding, a vinyl siding standoff (950), should be installed between the vent cap and the

exterior wall FIG-12. Attach the vinyl siding standoff to the horizontal termination. The vinyl siding standoff prevents

excessive heat from possibly melting the vinyl siding material. Note that the horizontal vent termination bolts onto the

flat portion of the vinyl siding standoff. (shaded area in FIG-12), so that an air space will exist between the wall and

the vent termination.

NOTES: (1) The horizontal run of vent pipe must be level and should have a ¼ inch rise for every one foot of run towards

the termination. Never allow the vent to run downward. This could cause high temperature and may present the

possibility of a fire

(2) The location of the horizontal vent termination on the exterior wall must not be easily blocked or obstructed.

Termination clearances are as follows:

(3) When installing a vent pipe in chase the minimum clearance to combustibles is 4” inches (100 mm).

VERTICAL INSTALLATION

STEP 1. Check the instructions for required clearances (air spaces) to combustibles when passing through ceilings, walls,

roofs, enclosures, attic rafters , or other nearby combustible surfaces. Do not pack air spaces with insulation.

STEP 2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to the position of the appliance

flue exit, and mark the location where the vent will penetrate the ceiling. Drill a small hole at this point. Next, drop a

plumb bob from the roof to the hole previously drilled in the ceiling, mark the spot where the vent will penetrate the

roof. Determine if ceiling joists, roof rafters, or other framing will obstruct the venting system. You may wish to

relocate the appliance, or to offset, to avoid cutting load bearing members.

STEP 3. To install the Round Support Box/Wall Thimble in a flat ceiling, cut a 10- inch square hole in the ceiling, centered in

the hole drilled in Step 2. Frame the hole as shown in FIG-16.

STEP 4. Assemble the desired lengths of black pipe and elbows necessary to reach from the appliance adapter up through

the Round Support Box. Insure that all pipe and elbow connections are in their fully twist-locked position.

STEP 5. Cut hole in the roof centered on the small hole placed in the roof from Step 2. The hole should be of sufficient size to

meet minimum requirements for Clearance to Combustibles, as specified. Continue to assemble lengths of pipe and

elbows necessary to reach from the ceiling Support Box up through the roofline. Galvanized pipe and elbows may be

utilized in the attic, as well as above the roofline. The galvanized finish is desirable above the roofline, due to the

higher corrosion resistance.

STEP 6. Once the pipe sections have been joined, and run up through the hole in he roof, slip an elbow strap (Part-989) over

the exposed sections, bend the support straps outwards, and push the Elbow Strap down to the roof level, as shown

in FIG 17. Tighten the clamp around the Pipe section. Use a level to make sure the pipe is truly vertical. With roofing

nails, secure the support straps to the roof. Seal the nails holes heads with non-hardening mastic. Trim the excess

length of the support straps that extend out beyond the edge of the flashing.

STEP 7. Slip the flashing over the pipe section protruding through the roof. Secure the base of the flashing to the roof with

roofing nails. Use a non-hardening sealant between the uphill edge of the flashing and the roof. Insure the roofing

material overlaps the top edge of the flashing as shown in FIG 17. Verify that you have at least the minimum

clearance to combustibles at the roofline.

STEP 8. Continue to add pipe sections until the height of the vent cap meets the minimum code requirements. FIG 22. Note

that for steep roof pitches, the vent height must be increased. In high wind conditions, nearby trees, adjoining roof

lines, steep pitched roofs, and other similar factors can result in poor draft, or down drafting. In these cases,

increasing the vent height may solve the problem.

STEP 9. Slip the Storm Collar over the pipe, and push it down to the top of the roof flashing as shown in FIG 17. Use the non-

hardening sealant around the joint between the pipe and the Storm Collar.

STEP 10. Twist lock the vent cap.

FIG-16 FIG-17

NOTES:

(1) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet, to avoid

excessive stress on the elbows, and possible separation. Wall straps are available for this purpose. FIG-18

(2) When ever possible, use 45°degree elbows instead of 90°degree elbows. The 45°degree elbow offers less

restriction to the flow of flue gases and intake air.

NOTES:

(1) For multi story installations. A ceiling firestop (part 963) is required at the second floor, and any subsequent floors.

FIG-19. The opening should be framed to 10-inch x 10-inch inside dimensions, in the same manner as shown in FIG-

16.

(2) Any occupied areas above the first floor, including closets and storage spaces, which the vertical vent passes

through, must be enclosed. The enclosure may be framed and sheetrocked with standard building materials. However

consult the appliance manufactures installation instructions for the minimum allowable clearance between the outside

of the vent pipe, and the combustible surfaces of the enclosure. Do not fill any required air spaces with insulation.
