READ ALL OF THESE INSTRUCTIONS CAREFULLY AND FOLLOW THEM EXACTLY !
These instructions are for model 6S and 8S chimneys used for 1,000° F for continuous burn and up to
1,400° F for periods up to one hour and 2,100° F for periods up to 10 minutes.
This chimney is suitable for use with appliances burning gas, oil, coal (NOTE: Certain types of coal
have a high sulfur content, which causes corrosion of stainless steel. Therefore this type of coal is not
recommended for use with factory built chimneys.) or wood such as cooking ranges, heating or fire-
place stoves, central furnaces, floor furnaces, hot water and steam heating boilers, recessed or unit
heaters, water heaters, domestic type incinerators, bakery ovens, and for industrial type low heat
appliances (NFPA - Table 9 - IP). (These chimneys shall be installed in accordance with local building
codes or as recommended by NFPA No. 211 and 54.) Chimneys installed without the use of the starter
section (6SS, 8SS) are listed to UL 103 (1,700° only), and may be connected to residential and building
heating appliances which are gas or oil fired ONLY, as specified in Note 3 to Table 1-2(a) of NFPA 211.
CONTACT LOCAL BUILDING OR FIRE OFFICIALS ABOUT RESTRICTIONS AND
INSTALLATION INSPECTIONS IN YOUR AREA.
The chimneys can be installed in single or multi-story buildings with maximum permissible overall
height from support to top of housing of 50’.
A minimum clearance of 2 inches of air space to combustible materials, building insulation,
enclosure walls, and roof must be maintained. Do not place any insulation material in clearance spaces
around pipe. Clearances at floor joists, and ceilings are established by the installation of the factory
furnished base supports and firestop shields and may be less than 2”. The flue gas exits must be a
minimum of 3’ above the roof and not less than 2’ above any projection within 10’.
A MAJOR CAUSE OF CHIMNEY RELATED FIRES IS
FAILURE TO MAINTAIN REQUIRED CLEARANCE (AIR
SPACES) TO COMBUSTIBLE MATERIALS, IT IS OF THE
UTMOST IMPORTANCE THAT THIS CHIMNEY BE
INSTALLED ONLY IN ACCORDANCE WITH THESE
INSTRUCTIONS.

Chimney to be sized in accordance with the appliance manufacturer’s instructions.
Single wall chimney connector may be used as the connection between the appliance and the first chimney
section whether it be at the ceiling or at the wall. Building codes require an 18” minimum clearance between
the single wall connector and all combustible surfaces. This clearance is not required at the ceiling when
connecting into the base support (CCB) or at the wall when connecting into a through the wall tee. Both of
these are UL tested installations.

Except for installation in one and two family dwellings, a factory-built chimney that extends through any floor
above that on which the connected appliance is located is to be provided with an enclosure having a fire
resistance rating equal to or greater than that of the floor or roof assemblies through which it passes.
The following installation applications take into account the various building constructions, single floor, two
floor, and multi-floor.
INSTALLATION OF 6S OR 8S CHIMNEY
1. Through the Ceiling Installation
Cut and frame a square opening in the ceiling to receive the base support (6SCCB or 8SCCB), 12 1/2”
square for 6S or 14 1/2” square for 8S. See Figure 2 and 2A.
Insert the base support (6SCCB or 8SCCB) from below the opening and raise until the flange contacts
the ceiling (or framing). From above drive 8d nails (5 each side) through pre-punched holes inside of
support. (see Figure 2)

Place the female end of the starter pipe section down over the centering flange on the base support
(6SCCB or 8SCCB) (Figure 3). Install first section of pipe into starter section by aligning the seams and
pressing straight down until a click is heard. Make sure that the insulation in the attic is removed from
around the framed opening, lower the insulation shield (6SIS or 8SIS) down over the pipe until it contacts
framing. Nail with 6d nails into the 12 1/2” or 14 1/2” frame using two (2) nails each side as shown in Figure
4. Make sure insulation shield and wood framing contain no opening through which loose insulation material
may enter (Figure 5C).
Place insulation shield collar over pipe and push down until it contacts top of the insulation shield. Make
sure there is no gap between collar and shield. Tighten the stove bolt and nut which draws the collar tight
around the pipe.
Continue installation as required (see Step 2).

APPLICATION (B) Two or More Story Installation of 6S and 8S Chimney
After the frame opening is completed for the ceiling base support (6SCCB or 8SCCB) and the base support
is installed in the first floor level, use a plumb-bob to align and locate the next framed opening in the next floor
levels. Frame an opening 12 1/2” square for 6S or for the 8S, 14 1/2” square. See Figure 2A, and 5. Framed
openings must line up precisely. Be sure to maintain the required minimum clearance to combustibles.
Install a radiation joist shield (6SJS or 8SJS) from below, at all floors (except roof), above base support with 6d nails
(2 each side, 2” from the ends). This provides firestop at the frame opening and establishes and maintains required
minimum clearance between chimney section and combustible materials in this area.
The final framed openings (to attic) requires the installation of an insulation shield (6SIS or 8SIS). (Remove insulation
from around this area.) Place the female end of the starter pipe section down over the centering flange on the base
support (6SCCB or 8SCCB) (see Figure 3).
Then assemble enough pipe sections to pass from base support (6SCCB or 8SCCB) through the joist shield (6SIS or
8SIS). Assemble pipe by aligning seams and pressing straight down until the click is heard. Remove any insulation or
other foreign materials from inside joist shield that might have fallen in.
Lower the insulation shield (6SIS or 8SIS) down from above, over the pipe until it sets on the framed opening. Using
6d nails, nail down with 2 nails on each side, 2” from the ends. See Figure 4. Next place insulation shield collar over
pipe and push down until it rests on top of insulation shield. Make sure there is no gap between collar and shield.
Tighten the stove bolt and nut which draws the collar tight around the pipe.
Continue installation as required (see Step 2).
STEP 2. Locate the center point where the chimney will pass through the roof by using a plumb-bob. Cut an opening
large enough to provide a minimum of 2” clearance all around the chimney section. See figure 5
showing frame opening size required.
3. Install the boot flashing (6 or 8SBF) making sure the flashing cone is centered over the roof opening so the
chimney pipe is plumb and the 2” air space clearances are maintained. Before attaching the flashing to
the roof, place a bead of caulk under the edges. Slip flashing under overlapping roof shingles as far as
possible before nailing flashing to roof. Trim, cut or replace shingles to fit cone as necessary. Thoroughly
caulk around edges of flashing. Add chimney sections until the pipe extends through the flashing (see Figure
8.)
4. Install storm collar (6 or 8 SSC) on the top pipe section and slide down until it contacts the high side of the
flashing cone. Put a bead of roofing cement between the storm collar and pipe section to insure a leak free
installation.
5. Chimneys shall extend at least 3 feet above the highest point where they pass through a roof of a building
and at least 2 feet higher than any portion of a building within a horizontal distance of 10 feet (see Figure 1).
If the chimney extends more than 6’, external bracing will be required. Plumbers tape may be wrapped
around chimney and secured with a minimum of three (3) guy wires anchored to roof, 120° apart (see Figure
8A).
6. Install the termination cap (6 or 8SU) tightening the screws on collar until the cap is fastened securely to
section.

OFFSETS
AirJet 30° elbows (6S30, 8S30) for factory built chimneys may be used where offsets are required. Straight
sections of pipe can be used between elbows to increase the amount of the offset. 30° is the maximum
allowable angle on offsets. The maximum angled run allowable is 6S - 8 feet, 8S - 8 feet. The 2” clearance
to combustibles requirement must be maintained.
Support the vertical return elbow by using the offset support (6SSB, 8SSB) (see Figure 5A). This offset
support is to be attached on or immediately above the vertical return elbow. NOTE: If elbow offset is located
in lower floors, offset support (6SSB, 8SSB) should be provided at each floor level (see Figure 5A). After
positioning the offset support and tightening the stove bolt and nut, attach support straps to the nearest
joists or frame by driving nails through the holes provided in the straps. Use two (2) 10d nails or #10 wood
screws per support strap. If additional support is desired, use plumbers tape and nail to structural rafters.
Complete installation as described earlier making sure 2” clearance to combustibles requirement is
maintained.
THROUGH THE WALL (6S and 8s Models only)
Figure 9A
12 1/2” - 6S
14 1/2” - 8S
4. Outside the house - place the tee (6ST, 8ST) on the support (6SWS,
8SWS) and line up the tee snout with the wall thimble. Place the
support flush against the wall and mark through the screw holes
onto the wall (see Figure 10). Remove the tee from the support and
screw the support to the wall at the marked location with nine (9) #10
screws. Place the tee, female end down, while sliding the snout
through the thimble making sure to maintain required clearance to
combustibles. Tee snout must protrude through the wall a minimum
of 1”. Snout is adjustable for 4 1/2” to 8” thick wall. For wall thickness
greater than 8”, it will be necessary to install a short (1 foot) chimney
section so that the proper clearances can be maintained and the
connector installation would not terminate inside the wall cavity.
3. Install and center wall thimble into inside opening. Nail with 6d nails
through the four (4) corners. Adjust thimble sleeve to proper wall
thickness. Maximum wall thickness covered by wall thimble is 8”.
See Figure 9.
2. Cut opening through the wall (see Figure 9) which provides required
air space clearance in every direction (6S - 12 1/2” square, 8S - 14 1/
2” square).
1. Mark the height on the wall as the center of the opening where the
single wall pipe meets the AirJet Chimney. Maintain minimum
clearance to combustible materials from single wall connector as
established by the local building codes. Most codes require at least
18” clearance from stove pipe to combustible surfaces. Stove pipe
is used only within the room from appliance to chimney tee. Never
enclose single wall stove pipe.

5. Add sections on top of tee, snap locking pipe sections
together making sure to align the seams.
6. Secure the pipe to the wall by installing a wallband (6SWB,
8SWB) every 5’. The bands should be attached with #10
screws. The center bracket of the band should be turned
so it is parallel to the pipe (see Figure 11). Tighten the
screws on the wall bands securely to form a secure anchor
against wind and weather.
7. Top of pipe must reach at least 3’ above roof. If pipe is 10’
or less from the roof peak or building projection, then it
must terminate at least 2’ above such peak or projection
height (see Figure 1).
8. Place termination cap (6SU, 8SU) down until it is firmly in
place. Tighten the screws on collar until cap is fastened
securely on the top pipe section.
9. Install weather shield (6SWSH, 8SWSH). Using
screws provided, place two halves of weather
shield around the tee to cover the outside wall
opening. Edges of the shield should be well
caulked to provide a weather-tight seal.
10. Inside the house, attach the face plate (6SFP,
8SFP) to the tee or chimney section, by placing
over the outer ring of the triple wall pipe.
NOTE: In geographical areas experiencing sustained
low ambient temperatures, it is recommended
that the exterior mounted chimney be enclosed
below the roof line. Enclosing the chimney
reduces heat loss, reduces condensation,
reduces creosote build-up and improves draft.
Remember to maintain 2” air space clearance
to combustibles and building installation.

NARROW OVERHANG
You can work around a narrow overhang by using two
(2) 30° elbows (6S30, 8S30) to offset the chimney. Two
elbows will give approximately 4” to 6” offset. If more offset
is needed, you will need to add a straight pipe section
between the elbows. One wall band should be placed just
below the first elbow, a second wall band should be
installed around the vertical return elbow. Second wall band
will require framing out from wall for attachment.
Remember to maintain the 2” clearance to combustible
requirement. Terminate as described in Step 8.
If the overhang is too wide for offsetting, finish the chimney
as you would with a ceiling installation. Remember to
maintain the 2” clearance to combustible requirement.
Cut the required opening in the roof, then use boot flashing
(6SBF, 8SBF), storm collar (6SSC, 8SSC), and round
termination cap (6SU, 8SU) as described in Step 3.

you will use. 6S - 12 1/2” square, 8S - 14 1/2” square.
2. Determine the roof pitch and make a template to match.
Mark this angle on the roof support (6SRS, 8SRS) and
cut to fit using tin snips. Nail through all four (4) sides
from above into the framing, using 8d nails, with at least
two (2) per side (see Figure 14).
3. Place starter pipe section into roof support (6SRS, 8SRS) with female end down over centering
flange. Install section of pipe onto starter section by aligning the seams and pressing straight down
until a click is heard. Slide boot flashing (6SBF, 8SBF) over pipe into place over roof opening. Lay
bead of caulk under edge of flashing. Check to see that chimney is vertical and attach flashing to
roof. Add caulk around edges.
4. Install storm collar (6SSC, 8SSC) and cap
(6SU, 8SU) to complete installation as
described in Step 8.

CREOSOTE AND SOOT - FORMATION AND NEED
FOR REMOVAL
CHIMNEY CLEANING PROCEDURES
THROUGH THE WALL CHIMNEY CLEANING
1. Loosen termination cap collar screws, and gently pull cap upward to remove. (On decorative housing,
unscrew four (4) screws and remove top cap assembly.) Carefully clean cap to top assembly with
a wire bench brush and/or a rough burlap or canvas cloth, or a chimney cleaning brush.
2. Disconnect the smoke (single wall) pipe from appliance. Be careful not to scatter the soot and fly
ash that will be inside. Remove each section of smoke pipe and take outdoors. Clean each section
in the same manner as the top was cleaned.
3. Place a plastic bag around the bottom section of chimney pipe. Seal the plastic bag around the
opening with tape so no debris will escape.
4. Assemble chimney cleaning brush and necessary rods (available at most hardware stores) as
described by the manufacture.
5. Insert the cleaning assembly (brush first) into open chimney flue and push or lower it progressively,
working it up and down with a twisting motion against the sides of the chimney flue. Continue to do
this until you have worked your way to the bottom.
6. The plastic bag may need to be emptied several times before the cleaning operation is completed.
7. Reassemble the smoke pipe and remount the termination cap or top assembly.
8. Inspect all chimney joints to be certain they are properly secured.
1. Follow instructions as outlined except as noted below for tee.
2. Remove the clean-out cap from under the tee support. Place a plastic bag under the support so it
will collect and hold debris. Seal the plastic bag around the opening with tape so no debris will
escape. Clean tee snout in the same manner as the top cap and smoke pipe sections were cleaned.
Shove debris toward tee support (outside) so it will be collected in the plastic bag. Then attach a
plastic bag around the tee snout in the same manner as on the tee support.
NOTE:If deposits are very heavy or you are unable to clean the chimney yourself, call a professional
contractor.
When wood is burned slowly, tar and other organic vapors are produced. These vapors combine with expelled
moisture from the burning wood to form creosote vapors. These creosote vapors condense in a relatively cool
chimney flue (below 250°). As a result, creosote residue accumulates and coats the lining of the pipe. Creosote
is highly combustible in its solid or semi-liquid state and burns at an extremely high temperature. When the
creosote ignites, a chimney fire results. The high temperatures of these fires could damage the chimney or
even cause a house fire. Read and follow closely the operating and maintenance instructions from the appliance
manufacture.
Even if the creosote does not catch fire, problems will result if the chimney is not checked and cleaned
properly on a regular basis. The creosote will continue to build up until it restricts the existing air flow (draft)
causing appliance heat production to decrease to a minimum.
The chimney should be inspected at least once every month during heating season to determine the extent of
creosote or soot build-up.
If creosote or soot has accumulated it should be removed by the following steps to reduce the risk of chimney
stoppage or fire.
First be sure fires and coals in the appliance are dead and the chimney pipe is cool. If possible, remove all
ashes from appliance.
