HORIZONTAL TERMINATION 4″ X 6-5/8″ (102 MM X 168 MM) VENTING (RIGID VENT SYSTEMS)
Minimum Vent Clearances to Combustibles

• Clearances noted below must be maintained, except when passing through a wall, ceiling, or at the termination where the use of a firestop or wall thimble reduces clearance to 1-1/2″ (38 mm).
  The recommended framing dimensions (inside measurements) for the 4″ x 6-5/8″ (102 mm x 168 mm) rigid vent terminations are below, for use with a firestop or wall thimble.

Recommended Framed Opening Size

Vent Size| Framing Size
4″ (102 mm) x 6-5/8″ (168 mm)| 10″ (254mm) x
10″ (254mm)

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 fittings are designed with special twist-lock connections to connect the venting system to the appliance flue outlet. A twist-lock appliance adaptor is required.

3. In conjunction with the approved vent system, install the adaptor after the unit is set in its location. Put a bead of Mill-Pac inside the outer section of the adaptor and a bead of Mill-Pac on the inner collar. Slip the adaptor over the existing inner and outer flue collar. Fasten to the outer collar only with the 3 supplied screws (drilling pilot holes will make this easier).

4. Level the fireplace and fasten it to the framing using nails or screws through the top and side nailing strips.

5. Assemble the desired combination of pipe and elbows to the appliance adaptor and twist lock for a solid connection.
   NOTES
   a. For best results and optimum performance with each approved venting system, application of Mil Pac sealant (supplied) to every inner pipe connection is recommended.  Failure to apply Mil-Pac may result in drafting or performance issues not covered under warranty.
   b. Horizontal runs of vent must be supported every 3 feet (0.9 m). Wall straps are available for this purpose.

6. Mark the wall for a square hole – see chart on this page for size. The center of the square hole should line up with the centerline of the horizontal pipe. Cut and frame the square hole in the exterior wall where the vent will be terminated. See diagram 2 for center line requirements.
   If the wall being penetrated is constructed of non-combustible material, i.e. masonry block or concrete, an 8″ (203 mm) diameter hole is acceptable.
   NOTES
   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 cause a fire.
   b) The location of the horizontal vent termination on an exterior wall must meet all local and national building codes.
   

7. Ensure that the pipe clearances to combustible materials are maintained (Diagram 3). Install the termination cap.
   NOTE
   • If installing termination on a vinyl siding covered wall, a vinyl siding standoff or furring strips must be used to ensure that the termination is not recessed into the siding.The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.

8. Before connecting the horizontal run of vent pipe to the vent termination, slide the wall thimble over the vent pipe. The wall thimble is required for all horizontal terminations.

9. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the vent cap assembly. It is important that the vent pipe extends into the vent cap far enough to create a minimum pipe overlap of 1-1/4 inches (32 mm). Secure the connection between the vent pipe and the vent cap.

10. Install the wall thimble in the center of the framed hole and attach it with wood screws (Diagram 4).

VERTICAL INLINE POWER VENT TERMINATIONS – RIGID PIPE

The minimum components required when using inline power vent are:
1 High Wind Cap
1 Rigid Pipe Adaptor (770-994) (50, 60 & 72 series)
1 Rigid Pipe Adaptor (Part #510-994) (40 series)
1 Ceiling Firestop
1 Flashing
1 Storm Collar
1 Lengths of pipe to suit wall thickness & vent run (see chart)
1 Vent Reducer (Part #946-606) (50, 60 & 72 series)
1 Inline Power Vent Kit

Galvanized pipe is desirable above the roofline due to its higher corrosion resistance. Continue to add pipe sections through the flashing until the height of the vent cap meets the minimum height requirements specified in table below or local codes. Note that for
steep roof pitches, the vertical height must be increased. A poor draft, or down drafting can result from high wind conditions near big trees or adjoining roof lines, in these cases, increasing the vent height may solve the problem.

When using Rigid Vent other than Simpson Dura-Vent, 3 screws must be used to secure rigid pipe to adaptor.

NOTES
The 40 series has a 4″ inner x 6 5/8″ outer (102 mm x 168 mm) collar already and does not require to be reduced in size.

HORIZONTAL TERMINATION – END OF LINE POWER VENT
4″ X 6-5/8″ (102 MM X 168 MM) RIGID VENTING

Minimum Vent Clearances to Combustibles

• Clearances noted below must be maintained, except when passing through a wall, ceiling, or at the termination where the use of a firestop or wall thimble reduces clearance to 1-1/2″ (38 mm).

Below are the recommended framing dimensions (inside measurements) for the 4″ x 6-5/8″ (102 mm x 168 mm) rigid vent terminations – for use with a firestop or wall thimble.

Recommended Framed Opening Size

Vent Size| Framing Size
4″ x 6-5/8″ (102 mm x 168 mm)| 13-1/2″ x 13-1/2″ (343 mm x 343 mm)

Install the vent system according to the manufacturer’s instructions, included with the components.

1. Set the unit in its desired location. Determine whether 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 fittings are designed with special twist-lock connections to connect the venting system to the appliance flue outlet. A twist-lock appliance adaptor is required.

3. In conjunction with the approved vent system, install the adaptor after the unit is set in its desired location. Put a bead of Mill-Pac inside the outer section of the adaptor and a bead of Mill-Pac on the inner collar. Slip the adaptor over the existing inner and outer flue collar. Fasten to the outer collar only with the 3 supplied screws (drilling pilot holes will make this easier).

4. Level the fireplace and fasten it to the framing using nails or screws through the top and side nailing strips.

5. Assemble the desired combination of pipe and elbows to the appliance adaptor and twist lock for a solid connection.
   NOTES
   • For best results and optimum performance with each approved venting system, application of Mil-Pac sealant (supplied) to every inner pipe connection is recommended. Failure to apply Mil-Pac may result in drafting or performance issues not covered under warranty.
   • Horizontal vent runs must be supported every 3 feet (0.9 m). Wall straps are available for this purpose.

6. Mark the wall for a square hole (see chart to left for size). The center of the square hole should line up with the centerline of the horizontal pipe. Cut and frame the square hole in the exterior wall where the vent will be terminated. See diagram 2 for  centerline requirements.

Vent Size| Framing Size
4″ x 6-5/8″ (102 mm x 168 mm)| 13-1/2″ x 13-1/2″ (343 mm x 343 mm)

1. Locate the unit in the framing and rough in the gas, preferably on the right side of the unit. Locate the centerline of the termination and mark the wall accordingly. Cut a square hole in the wall (see chart for inside dimension.)

2. Level the fireplace and fasten it to the framing using nails or screws through the nailing strips.

3. Assemble the vent by applying Mill Pac to the inner flue collar of the termination and slipping the inner flex liner over by at least 1-3/8″ (35mm) over it. Fasten with the three screws (drilling pilot holes will make this easier).

4. Apply Mill-Pac to the outer flex pipe and slip it over the outer flue collar of the vent terminal by at least 1-3/8″(35mm). Fasten with the three screws.
   NOTE
   Horizontal sections must be supported at intervals not exceeding 3 feet (0.9 meter).
   Flame picture and performance will be affected by sags in the liner.

5. Slip the assembled liner and termination assembly through the thimble. Check the markings on the termination cap to ensure it is facing up; this will position the termination cap with the proper down slope for draining water. Fasten the cap to the outer wall with the 4 supplied screws.

6. Pull the centre inner and outer flex liner out enough to slip over the flue collars of the fireplace a minimum of 1-3/8″ (35mm). You may wish to cut the liner shorter to make it more workable. Do not bend the liner more than  90°.

7. Apply Mill-Pac over the fireplace inner flue collar and slip the inner flex liner down over it. Attach with three supplied screws.

8. Do the same with the outer flue collar and outer flex liner.

9. Apply a bead of silicone between the thimble and termination and around the outer edge of the terminal at the wall in order to keep the water out.

IMPORTANT
Do not locate termination hood where excessive snow or ice buildup may occur. Check vent termination area after snowfalls and clear to prevent blockage of the venting system. When using snow blowers, make sure snow is not directed toward vent termination area.

VERTICAL INLINE POWER VENT TERMINATIONS – RIGID PIPE

NOTE
A top clearance of 3″ (76 mm) and side bottom clearance of 2″ (51 mm) must be maintained, except when passing through a wall or ceiling or at the termination where a firestop or wall thimble reduces the required clearance to 1-1/2″ (38 mm).
We recommend framing an 11″ (279 mm) x 11″ (279 mm) (inside dimensions) hole to give structural rigidity for mounting the termination.

1. Maintain the 1-1/2″ (38 mm) clearances (air spaces) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces, and ensure that a firestop or wall thimble is used as noted above. Do not pack air spaces with insulation.
   Check the “Venting Arrangement for Vertical Terminations” section for the maximum vertical rise of the venting system and the maximum horizontal offset.

2. Set the gas appliance in its the desired location. Drop a plumb bob from the ceiling to the appliance flue exit and mark 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 drilled in the
   ceiling and mark where the vent will penetrate the roof. Determine whether 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 Diagram 2 to avoid cutting load bearing members.

3. A firestop spacer must be installed in the floor or ceiling at every level.

4. Assemble the desired pipes and elbows.
   Ensure all pipes and elbow connections are twist-locked and sealed.
   Cut a hole in the roof, centered on the small hole drilled in step 2. The hole should be sized to meet the minimum requirement of 1-1/2″ (38 mm) clearance to combustibles. Slip the flashing under the shingles as per Diagram 4 (shingles should overlap half of the flashing).

5. A minimum of 4 feet is required between the unit and the inline power vent. Determine the overall height of the chimney from the top side of the inline power vent to the underside of the flashing.
   NOTE
   For best results and optimum performance with each approved venting system, Mill Pac sealant is strongly recommended at every inner pipe connection. Failure to use Mill-Pac may result in drafting or performance issues not covered under warranty.
   Diagram 4 -The upper half of the flashing is installed under the roofing material and not nailed down until the chimney is walstrp. eps installed, to allow for small adjustments.

6. Continue to assemble pipe lengths. Support the inline power vent to avoid excessive stress on the pipe and elbows. The inline power vent can be screwed onto existing studs for support.
   Galvanized pipe is desirable above the roofline due to its higher corrosion resistance. Continue to add pipe sections through the flashing until the height of the vent cap meets the minimum height requirements specified in Diagram 5 or local codes.
   Note that for steep roof pitches, the vertical height must be increased.
   NOTE
   If an offset is needed in the attic, it is important to support the vent pipe at every 3 ft (0.9 m) to avoid excessive stress on the elbows and possible separation.
   Wall straps are available for this purpose (Diagram 2).
   Roof Pitch| Minimum Vent Height
   ---|---
   Feet| Meters
   flat to 7/12| 2| 0.6
   over 7/12 to 8/12| 2| 0.6
   over 8/12 to 9/12| 2| 0.6
   over 9/12 to 10/12| 2-1/2| 0.8
   over 10/12 to 11/12| 3-1/4| 1
   over 11/12 to 12/12| 4| 1.2
   over 12/12 to 14/12| 5| 1.5
   over 14/12 to 16/12| 6| 1.8
   over 16/12 to 18/12| 7| 2.1
   over 18/12 to 20/12| 7-1/2| 2.3
   over 20/12 to 21/12| 8| 2.4

A poor draft, or down drafting, can result from high wind conditions near big trees or adjoining roof lines. Increasing the vent height may solve this problem.

7. Ensure vent is vertical and secure the base of the flashing to the roof with roofing rails. Slide the storm collar over the pipe section and seal with mastic.
8. Install and twist lock the vertical termination cap.

NOTE
Any closets or storage spaces that the vent passes through must be enclosed.

VERTICAL INLINE POWER VENT TERMINATIONS FLEX PIPE (PART # 946-755)
Must choose 1 of the following:

IMPORTANT

• For the City 50, 60 Series & City 72 Series models, you must purchase the 946-758 reducer for the top of the appliance. It must be attached to the inner and outer flue collar of the appliance prior to installation.
• The roof flashing is not included with this kit and
  must be purchased separately.

1. Maintain the 1-½” (38 mm) clearance (airspace) to combustibles when passing through ceilings, walls, floors, enclosures, attic rafters, or other combustibles. Do not pack air spaces with insulation. Check venting sections of this manual for the maximum vertical rise of the venting system and the maximum horizontal offset limitations. Ensure that you maintain clearances around enclosures and walls, and below or above floors, floor joists, etc. Each appliance has different clearance requirements (top, sides, bottom). See specific appliance manual for details.

2. Set the appliance in its desired position. Drop a plumb bob down from the ceiling/floor joist 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 at the ceiling level and mark the spot where the vent will penetrate the roof.

3. Cut a hole in the roof centered on the small hole placed in the roof in the previous steps. The hole should be a minimum of 10-¼ inches. The hole may be round and or square.

4. Slip the flashing under the shingles and line it up so it is centered on the hole. Shingles should overlap half of the flashing, as per Diagram 1. Diagram 1; The upper half of the flashing is installed under the roofing material and not nailed down until the chimney is installed. This allows for small adjustments.

5. A ceiling firestop/firestop spacer must be installed when passing through each floor or ceiling level. To install the ceiling firestop/firestop spacer in a flat ceiling or floor joist, cut a 10- ¼ inch square hole. Frame the hole as show in Diagram 2 and install the ceiling firestop. Slide the top attic insulation spacer onto the top of the attic insulation shield/ firestop (see Diagram 2a). Secure with four screws/nails. If more than one is required, these can be purchased separately.
   NOTE
   • The ceiling firestop/firestop spacer may be cut down to size if it is too high for the application.

6. Determine the overall height of the chimney from the top of the appliance to the underside of the inline power vent. If required, cut the flexible inner and outer pipe to the desired length, up to a maximum of 20 feet (3.7 m).

7. Put a bead of Mill-Pac around the 4″ (102 mm) collar on the appliance and slide the inner flex pipe over the inner collar of the appliance and secure with a minimum of three screws.

8. Install 4″ (102 mm) spacers around 4″ (102 mm) flex.

9. Repeat Step 7 to install the outer pipe to the outer collar of the appliance.

10. Repeat Step 7 to secure 4″ (102 mm) flex to inline power vent. Repeat steps to attach outer collar to inline power vent.
    NOTE
    • If an offset is necessary in the attic or floor joists it is important to support the vent pipe every 3 feet (914 mm) to avoid excessive stress and sagging of the vent pipe. Wall straps (3 in total) are provided for this purpose. All round/ plumbers strapping may also be used if further supports are required.

11. Determine the overall height of the chimney from the top side of the inline power vent to the underside of the flashing. If required, cut the flexible inner and outer pipe to the desired length.

12. Put a bead of Mill-Pac around the inner pipe adaptor (supplied with the inline power vent) and attach the inner pipe adaptor to the inner collar of the inline power vent (see Diagram 3, next page).

13. Put a bead of Mill-Pac around the other end of the inner pipe adaptor and slide the 4″ (102 mm) flex over it; secure with three screws.

14. Install 4″ (102 mm) spacers around 4″ (102 mm) flex.

15. Put a bead of Mill-Pac around the outer collar of the inline power vent and slide outer pipe over the inline power vent; secure with 3 screws.

16.  Attach the rigid pipe section to the flex-to-rigid adaptor using Mill-Pac on the inner/outer pipe. Use three screws to secure outer pipe.

17. Use Mill-Pac to secure the inner flex pipe to the pipe adaptor. Slide the inner pipe over the flex-to-rigid adaptor and secure with three screws.

18. Repeat Step 17 to secure outer flex.
