other appliances connected to the flue.
WARNING
Diagonal runs have both vertical and horizontal vent aspects
when calculating the effects. Use the rise for the vertical
aspect and the run for the horizontal aspect. Figure 5.1.
Two 45° elbows may be used in place of one 90° elbow. On
45° runs, one foot of diagonal is equal to 8-1/2 in. (216mm)
horizontal run and 8-1/2 in. (216mm) vertical run. A length
of straight pipe is allowed between two elbows. Figure 5.1.

CAUTION
ALL vent configuration specifications MUST be followed.
• This product is tested and listed to these
specifications.
• Appliance performance will suffer if specifications are
not followed.
Figure 5.1
• Pipe measurements are from center line to center line.
• Horizontal terminations are measured to the outside of
the mounting surface (flange of termination cap). See
Figure 4.1 on page 8.
• Vertical terminations are measured to the top of the last
pipe before termination cap.
• Horizontal pipe installed level with 1/4 in. (6mm) rise.
•A round support box/wall thimble or heat shield is
required when the venting passes through a combus-
tible wall.

D. How to Use the Vent Graph
1. Measure the distance from the top of appliance to the
center of the 90° elbow. On the graph below, draw a
horizontal line from that measurement on the vertical
axis across until it intersects with the slanted line.
2. From the point of this intersection, draw a vertical line to
the bottom of the graph.
3. The point at which this line meets the bottom line of the
graph is the maximum length of the horizontal run.
EXAMPLE 1: If the vertical dimension from the center line
of the flue vent to the center of the 90° elbow is 7 ft. (2 m),
the horizontal run to the outer wall flange must not exceed
13 ft. 2 in. (5m).
EXAMPLE 2: If the vertical dimension from the center line
of the flue vent is 21 ft. (6m), the horizontal run to the outer
wall flange must not exceed 10 ft. (3m).
4. Each 90° elbow is equivalent to 3 ft. (914mm) of vent
pipe and each 45° elbow is equivalent to 1 ft. (305mm)
of vent pipe, and must be subtracted from vent pipe
run. A single vertical to horizontal 90° elbow is already
calculated into the allowable 15 ft. (5m) run. Each
additional 90° elbow reduces the maximum horizontal
distance by 3 ft. (914mm).
Figure 5.2
TOTAL HORIZONTAL RUN TO THE OUTER
WALL FLANGE (EXCLUDING ELBOWS)
Example: The use of 3 elbows would reduce the
allowable horizontal run to 9 ft. (3 - 1 = 2 elbows x 3 ft. =
6 ft.; 15 ft. max. - 6 ft.= 9 ft. max.)

Female Locking Lugs
Male Locking Lugs
Step 1.
Determine the desired location of the appliance. Check to
ensure that wall studs or roof rafters are not in the way when
the venting system is attached. If this is the case, you may
want to adjust the location of the appliance.
Figure 5.5
Step 2.
Direct vent pipe is designed with a locking connection. To
connect the venting system to the appliance flue outlet, a
twist-lock adapter is built into the appliance at the factory.
Wall thickness may vary. Remember to include wall
thickness in minimum clearances when figuring venting
lengths for your installation needs.
Note: Female ends of direct vent pipe/elbows are
designed to slide straight onto the male ends of adjacent
pipes by orienting the pipe indentations so they match and
slide into the entry slots on the male ends, see Figure 5.5.
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
may not be visible from the outside. They may be located by
examining the inside of the female ends.

Step 3.
For installations using a round support box/wall thimble
(check pipe manufacturer's instructions), mark the wall for a
10 in. x 10 in. (254mm x 254mm) square hole. The center
of the square hole should line up with the center line of the
horizontal pipe, as shown in Figure 5.6. Cut and frame the
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 block or concrete, a 7 in. (178mm)
diameter hole is acceptable.
NOTE:
(1) Installation requires a minimum of 6 in. (152mm)
horizontalrunofventwitha1/4in.(6mm)riseruntowards
the termination. Each 1 ft. (305mm) of horizontal venting
must include a 1/4 in. (6mm) rise. Never allow the vent
to run downward. This could cause high temperatures
and may present the possibility of a house or structure
fire.
(2) The location of the horizontal vent termination on an
exterior wall must meet all local and national building
codes, and must not be easily blocked or obstructed,
see Figure 4.4 on page 9.
(3) For installations requiring a vertical rise on the exterior
of the building, a snorkel kit is available with a 14 in.
(356mm) and a 36 in. (914mm) tall snorkel termination
cap. Follow the same installation procedures as used
for standard horizontal terminations. If the snorkel
terminationmustbe installedbelowgrade(i.e.basement
application), proper drainage must be provided to
prevent water from entering the snorkel termination. Do
not backfill around snorkel termination.
(4) Vertical clearances through a wall require 2 in. (51mm)
off the top of the venting pipe and 1 in. (25mm) off the
sides and bottom.

Step 4.
Positionthehorizontalterminationcap in thecenterofthe10
in. x 10 in. (254mm x 254mm) square hole and run a bead
of non-hardening mastic around its outside edges, so as to
make a seal between it and the wall, attach termination cap
to the exterior wall with the four wood screws provided. The
arrow on the vent cap should be pointing up (Figure 5.7).
NOTES:
(1) The four wood screws provided should be replaced with
appropriate fasteners for stucco, brick, concrete, or
other types of sidings.
(2) A termination cap with a built-in vinyl siding standoff is
highly recommended on a building with vinyl siding. The
pilot hole will be 2 in. (51mm) closer to the bottom of the
square than the top. Using a framing square, draw a 14
in. x 14 in. (356mm x 356mm) square around the pilot
hole in the siding. Figure 5.7.

Step 5.
Place the wall thimble cover over the pipe assembly and
slide the appliance and vent assembly towards the wall,
carefully inserting the vent pipe into the vent termination
cap assembly. It is important that the vent pipe extend into
the vent termination cap a sufficient distance so as to result
in a minimum pipe overlap of 1-1/4 in. (32mm). Secure the
connection between the vent pipe and the vent termination
cap by attaching the two sheet metal strips extending from
the vent termination cap assembly into the outer wall of
the vent pipe. Use the two sheet metal screws provided to
connect the strips to the pipe section (Figure 5.10).
Note: The attachment from the vent pipe to the vent cap
must be sealed with silicone. Venting terminals shall not be
recessed into a wall or siding.

clearances to combustible materials are maintained.
If you are not using an approved termination cap with
a built-in standoff on a building with vinyl siding, a
vinyl siding standoff should be installed between the
termination cap and the exterior wall (Figure 5.99).
Follow manufacturer’s instructions for attaching the
vinyl siding standoff to the horizontal termination cap.
The vinyl siding standoff prevents excessive heat from
possibly melting the vinyl siding material. Remove
siding from the area where the standoff will be located.

Step 1.
Check the installation instructions for required 1 in. (25mm)
clearances (air space) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters, or
other nearby combustible surfaces. Figure 5.17 on page
17. Check the instructions below for maximum vertical rise
of the venting system, and any maximum horizontal offset
limitations. All offsets must fall within the set parameters of
the vent graph Figure 5.2 on page 11.
NOTE: Maximum vertical rise allowable is 40 ft. (12m)
Figure 5.11).
NOTE: Maximum number of 45° elbows permitted for a
vertical installation is eight, provided their installation
does not decrease maximum allowable horizontal run (as
specified by vent graph, on page 11).

Step 2.
Set the gas appliance in its 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,
and 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, as shown in Figure 5.13 on page16,
to avoid cutting loadbearing members. When location is
determined, drill small hole.

NOTE:
(1) If an offset is necessary in the attic to avoid obstructions,
it is important to support the vent pipe every 3 ft.
(914mm) to avoid excessive stress on the elbows, and
possible separation. Wall straps are available for this
purpose, Figure 5.13.
(2) Whenever possible, use 45° elbows, instead of 90°
elbows. The 45° elbow offers less restriction to the flow
of flue gases and intake air.
Step 7.
Continue to assemble pipe sections until the height of the
vent (before adding the termination cap) meets the minimum
coderequirementsasoutlinedinthecurrentCAN/CGA-B149
Installation Codes (in Canada), the National Fuel Gas Code
NFPA 54/ANSI Z223.1 (in USA), or local codes. Note that
for steep roof pitches, the vent height must be increased.
See Roof Pitch Table Figure 4.3 on page 8. In high wind
conditions, nearby trees adjoining rooflines, steep pitched
roofs, and other similar factors can result in poor draft, or
down drafting. In these cases increasing the vent height or
switching to the high wind termination cap may solve this
problem.
Step 3.
To install the round support box/wall thimble cover in a flat
ceiling, cut a 10 in. (254mm) square hole in the ceiling,
centered on the hole drilled in Step 2. Frame the hole as
shown in Figure 5.14.

a bead of non-hardening mastic around the top edges of the
support box to make a seal between it and the roof. Clean
out any combustible material from inside the support box.
Step 6.
Complete the cathedral ceiling installation by following the
same procedures outlined in steps 4 through 8 for vertical
installations, pages 16-17.
Step 7.
Place the support clamp (provided with the support box)
insidethe supportbox (atthe bottom),and secureto thepipe
section. The clamp allows the support box to support the
weight of the pipe sections. Continue to add pipe sections
until you are above the roofline.

Step 8.
Installthe black trim collar aroundthe outside of the cathedral
ceiling support box Figure 5.20. The two pieces of the trim
collar slide over one another to allow for easy adjustment
around the support box. Using the six screws provided,
secure the four corners and the overlapping sections of the
trim collar to the ceiling. You may want to predrill the holes for
the overlapped sections for ease of installation.

Step 4.
Pass the flex pipe down through the center of the chimney
system, and center the top adapter on the top of the chimney
pipe. Drill four 1/8 in. (3mm) diameter holes through the
top adapter, and into the chimney top. Ensure that you are
drilling into the metal on the chimney. Twist lock the high
wind termination cap onto the top adapter Figures 5.23 and
5.24.
Step 5.
Pull the flex pipe down through the ceiling support box, until
it protrudes approximately 3 in. (76mm). Connect the flex
pipe to the retro connector, and attach with sheet metal
screws.
Step 6.
Push the flex pipe back up into the ceiling support box,
center the retro connector, and attach it to the support box
with sheet metal screws.
Step 7.
The connection between the appliance and the retro
connector may be completed with sections of direct vent
pipe.

Step 1.
Remove existing chimney cap.
Step 2.
Measure the distance from the top of the chimney to the
bottom of the ceiling support box, add 3 in. (76mm) to this
measurement, and cut a section of 4 in. (101mm) flex pipe
to that length (the flex should be fully extended).
Step 3.
Connect the end of the flex pipe section to the underside
of the top adapter, using four sheet metal screws Figure
5.22.
CAUTION
Ensure that existing chimney is functionally sound and clean.
• Have inspection done by qualified chimney sweep or
professional installer BEFORE converting to direct vent
appliance.
