C. Measuring Standards
Vertical and horizontal measurements were made using the
following standards.
1. Pipe measurements are from center line to center line.
2. Horizontal terminations are measured to the outside
mounting surface (ange of termination cap) (see Figure
4.1) on page 9.
3. Vertical terminations are measured to the top of the last
pipe before termination cap.
4. Horizontal pipe installed level with 1/4 inch rise per foot.

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 top of the
appliance to the center of the 90° elbow is 7 ft. (2 m), the
horizontal run to the outer wall ange must not exceed 13
ft. (4 m).
Example 2: If the vertical dimension from the top of the
appliance is 21 ft. (6.4 m), the horizontal run to the outer
wall ange must not exceed 9 ft. (3 m).
4. Each 90° elbow is equivalent to 3 ft. (914 mm) of vent
pipe and each 45° elbow is equivalent to 1 ft. (305 mm)
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. (5 m) run. Each
additional 90° elbow reduces the maximum horizontal
distance by 3 ft. (914 mm).
Example: The use of three 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.)
E. Venting Guidelines
• Minimum 2 ft. vertical rise for top vent installations before
first elbow.
• The maximum horizontal vent run is 15 ft. (5 m) when the
vertical vent rise is 10 ft. (3 m).
• The minimum horizontal vent run is 11-5/8 in. (295 mm).
• Horizontal sections require a 1/4 in. (6 mm) rise for every
12 in. (305 mm) of horizontal travel.
•
Horizontal sections require noncombustible support every
3 ft. (914 mm), e.g. wall strap.
• Wall thickness: Minimum 4 in. (102 mm). Maximum 20 in.
(508 mm).
• Vent Diameter: Exterior 6-5/8 in. (168 mm); Inner 4 in.
(102 mm).
EXCEPTION FOR REAR VENT KIT
INSTALLATION:
• The maximum horizontal vent run is 2 ft. (610 mm).
NOTICE: Maximum horizontal vent run is 18 in. (457 mm)
when using the HRC termination cap.
• The maximum horizontal vent run with a 45° elbow is 18
in. (457 mm).
•
No external minimum rise is required. The minimum
horizontal vent run is 11-5/8 in. (295 mm).
• For any vertical rise when rear venting, a minimum of 2
ft. (610 mm) vertical must be used prior to any horizontal
run.
• If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed. If wall
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed. If wall thickness
is greater than 7-1/4 in. a DVP-HSM-B will be required.
• SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to 194 mm thick).

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.
3. 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
5.4. Align the seam of the pipe and seam of collar to
allow engagement. Rotate the vent component to lock
into place. Use this procedure for all vent components.
See Figure 10.5. Continue adding vent components,
locking each succeeding component into place. Ensure
that each succeeding vent component is securely tted
and locked into the preceding component.

WARNING
Fire Risk, Explosion Risk, Combustion
Fume Risk.
Use vent run supports per installation
instructions.
Connect vent sections per installation
instructions.
• Maintain all clearances to combustibles.
• Do NOT allow vent to sag below
connection point to appliance.
• Maintain specied slope (if required).
Improper support may allow vent to sag or separate.
Fire Risk, Exhaust Fumes Risk
Impaired Performance of Appliance
• Ensure vent components are locked
together correctly.
• Pipe may separate if not properly joined.
4. For installations using a round support box/wall thimble
(check pipe manufacturer's instructions), mark the wall
for a 10 in. x 10 in. (254 mm x 254 mm) square hole.
The center of the square hole should line up with the
center line of the horizontal pipe, as shown in Figure
5.5. Cut and frame the hole in the exterior wall where
the vent will be terminated. If the wall being penetrated
is constructed of noncombustible material, i.e. masonry
block or concrete, a 7 in. (178 mm) diameter hole is
acceptable.
5. Installation requires a minimum of 6 in. (152 mm)
horizontal run of vent with a 1/4 in. (6 mm) rise run towards
the termination. Each 1 ft. (305 mm) of horizontal venting
must include a 1/4 in. (6 mm) rise. Never allow the vent
to run downward. This could cause high temperatures
and may present the possibility of a fire. 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
10.
6. For installations requiring a vertical rise on the exterior of
the building, the HHT RHVK snorkel kit (Part #844-8921)
is available with a 14 in. (356 mm) and a 36 in. (914 mm)
tall snorkel termination cap. Follow the same installation
procedures as used for standard horizontal terminations.
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. Do not backfill around snorkel termination.
7. Position the horizontal termination cap in the center of

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 5.6).

8. The four wood screws provided should be replaced with
appropriate fasteners for stucco, brick, concrete, or other
types of sidings.
9. Termination cap HHW2 (Part #841-0670) is highly
recommended on a building with vinyl siding, as the vinyl
siding standoff is built in. The pilot hole will be 2 in. (51
mm) closer to the bottom of the square than the top.
Using a framing square, draw a 14 in. x 14 in. (356 mm x
356 mm) square around the pilot hole. See Figure 5.7.
Figure 5.7
10. If you are installing termination cap HHW2, the pipe
will be off center on flashing). Ensure that proper
clearances to combustible materials are maintained. If
you are using an approved termination cap other than
HHW2 (part #841-0670) on a building with vinyl siding,
a vinyl siding standoff should be installed between
the termination cap and the exterior wall (Figure 5.8,
on the next page). 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. The vent terminal cap shall not be recessed
into a wall or siding. Remove siding from the area where
the standoff will be located.
11. Place the wall thimble cover over the pipe assembly and
Note: The attachment from the vent pipe to the vent
termination cap must be sealed with silicone. Termination
caps shall not be recessed into a wall or siding.
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. (32 mm).
WARNING
Fire Risk, Exhaust Fumes Risk
Impaired Performance of Appliance
• Ensure vent components are locked
together correctly.
• Pipe may separate if not properly joined.

1. Check the installation instructions for required 1 in.
(25 mm) clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, or other nearby combustible surfaces. Check
the instructions 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).
WARNING
Do NOT connect a pipe section to a termination cap
without using the telescoping ue section found on the
termination cap.
WARNING
Burn Risk
• Local codes may require installation of a
cap shield to prevent anything or anyone
from touching the hot cap.
Note: Maximum vertical rise allowable is 40 ft. (10.7 m),
Figure 5.11. Maximum number of 45° elbows permitted
for a vertical installation is eight, provided their installation
does not decrease maximum allowable horizontal run (as
specied by vent graph, Figure 5.2).
WARNING
Fire Risk, Explosion Risk
Maintain vent clearance to combustibles as
specied.
• Do not pack air space with insulation or
other materials.
Failure to keep insulation or other materials
away from vent pipe may cause re.

a flat ceiling, cut a 10 in. (254 mm) square hole in the
ceiling, centered on the hole drilled in Step 2. Frame the
hole as shown in Figure 5.12.

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 5.11 to avoid cutting load
bearing members.
Figure 5.11
Figure 5.12
4. Assemble the desired lengths of pipe and elbows
necessary to reach from the appliance up through
the round support box. Ensure that all pipe and elbow
connections are in their fully twist-locked position.
Assemble as instructed.
5. Cut a hole in the roof centered on the small drill hole
placed in the roof in Step 2. The hole should be of
sufficient size to meet the minimum requirements for
clearance to combustibles, as specified. Continue to
assemble lengths of pipe and elbows necessary to reach
from the ceiling support box/wall thimble up through the
roof line. 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 its higher
corrosion resistance.
• If an offset is necessary in the attic to avoid obstructions,
it is important to support the vent pipe every 3 ft. (914
mm) to avoid excessive stress on the elbows, and
possible separation. Wall straps are available for this
purpose, Figure 5.11.
• Whenever possible, use 45° elbows, instead of 90°
elbows. The 45° elbow offers less restriction to the flow
of flue gases and intake air.
6. Slip the flashing over the pipe section(s) protruding
through the roof. Secure the base of the flashing to
the roof with roofing nails. Ensure the roofing material
overlaps the top edge of the flashing as shown in Figure
5.13. Verify that the chimney is the required height above
the roof. See roof pitch table, Figure 4.2.
7. Continue to assemble pipe sections until the height of
the vent (before adding the termination cap) meets the
minimum code requirements as outlined in the current
CAN/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
4.2). 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.
8. Slip the storm collar over the pipe, and push it down to
the top of the flashing (Figure 5.14). Use non-hardening
sealant above and below the joint between the storm
collar and the pipe.
9. Twist-lock the vent cap and seal.
Note: For multi-story vertical installations, a ceiling firestop
is required at the second floor, and any subsequent floors
(Figure 5.16). The opening should be framed to 10 in. x
10 in. (254 mm x 254 mm) inside dimensions, in the same
manner as shown in Figure 5.12.
• Any occupied areas above the first floor,
including closets and storage spaces,
which the vertical vent passed through
must be enclosed. The enclosure may be
framed and sheet rocked with standard
construction materials; however, refer
to these 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 of the required air space with
insulation.
H. Secure the Vent Sections
!
• Vertical runs of SLP pipe must be supported every 8 ft.
(2.44 m).
• Horizontal sections must be supported every 5 feet (1.52
m).
• Vent supports or plumbers strap (spaced 120º apart) may
be used to support vent sections. See Figures 5.16 and
5.17.
• Wall shield restops may be used to provide horizontal
support to vent sections.
• SLP ceiling restops have tabs that may be used to provide
vertical support.
WARNING
RISK OF FIRE, EXPLOSION OR ASPHYXIATION!
Improper support may allow vent to sag and separate.
Use vent run supports and connect vent sections per
installation instructions. DO NOT allow vent to sag below
connection point to appliance.
I. Disassemble Vent Sections
• Rotate either section (see Figure 5.18) so the seams on
both pipe sections are aligned as shown in Figure 5.19.
