*NOTE: When using the optional Vignette finishing trim, this can be installed as a 3-sided or 4-sided finish trim. If choosing to use this as a 4-sided finish trim the framing would need to be increased by 11/16″ inches minimum for this to fit. This must be to the finished floor. (Eg:42″ framing height + 11/16″ to bottom of 4-sided finishing trim +1/2 thick finished floor = 43 3/16

Important: Framing height requires consideration of the hearth depth. Dimension N = N + the thickness of the installed hearth.

NON- NON-COMBUSTIBLE REQUIREMENTS

FINISHING

IMPORTANT FINISHING DETAIL NOTE: Before placing the unit into the final position – it is important to know the total thickness/height of the finished hearth (tile, carpet, etc.)
The base of the fireplace should be level or higher than the finished hearth height.

• Note: All non-combustible facing material should butt up cleanly **** to the flanges around the firebox opening.
• Rough edges will be visible from the front view with the flush louvres or flush panels – if not using the optional finishing trim.
• To maintain a clean finished edge – it is recommended to install the non-combustible facing material with the finished edge against the fireplace/nailing strips.
• Alternatively, you can use J Style Trim or Metal Corner Bead to cover the cut edges of the non-combustible facing material.
• Important: Finishing materials such as tile, river rock, etc, must not protrude beyond the front-facing flanges at the sides and top of the firebox opening.

UNIT INSTALLATION

WITH HORIZONTAL TERMINATION 4″ X 6-5/8″ OR 5″ X 8″ 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″ (38mm).

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

Recommended Framed Opening Size

Vent Size| Framing Size
4″ x 6 – 5/8″| 10″ x 10″
5″ x 8″| 11″ x 11″

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 desired location. Put a bead of Mill-Pac inside the outer section of the adapter and a bead of on the inner collar. Slip the adapter 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.
   • Note: For best results and optimum performance with each approved venting system, it is highly recommended to apply the “Mill-Pac” sealant (supplied) to every inner pipe connection.
   • Failure to do so may result in drafting or performance issues not covered under warranty. Horizontal runs of the vent must be supported every 3 feet (0.9 meters). Wall straps are available for this purpose.
6. Mark the wall for a square hole.-see chart to left for size. The centre of the square hole should line up with the centre line 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″ (203mm) diameter hole is acceptable.
   • Note:
   • a) The horizontal run of the 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 may present the possibility of a fire.
   • b) The location of the horizontal vent termination on an exterior wall must meet all local and national building codes, and must not be blocked or obstructed. See the “Exterior Vent Termination Locations” section for more details.
   • c) Snorkel Terminations:
   • For installations requiring a vertical rise on the exterior of the building, 14-inch and 36-inch tall snorkel terminations as shown in Diagram 2 are available, as well as the standard riser vent.
   • Follow the same installation procedures as used for standard horizontal termination. NEVER install the snorkel upside down.
   • Note: Riser vent is only for use in above-grade terminations.
   • NOTE: For snorkel terminations in ABOVE grade installations, follow national or local code requirements.
   • The vent riser is only available with 4″ x 6-5/8″ venting. With 5″ x 8″ venting, use an optional snorkel termination.
   • Below-Grade Snorkel Installation
   • 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 attempt to enclose the snorkel within the wall or any other type of enclosure. See diagram 2c.
7. Ensure that the pipe clearances to combustible materials are maintained (Diagram 5). 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 the 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. The vent pipe must extend into the vent cap sufficient distance to result in a minimum pipe overlap of 1-1/4 inches (32mm). Secure the connection between the vent pipe and the vent cap.
10. Install a wall thimble in the centre of the framed hole and attach it with wood screws (Diagram 4).

UNIT INSTALLATION WITH HORIZONTAL TERMINATION 5″ X 8″ VENTING (Flex 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″ (38mm).

Below are the recommended framing dimensions (inside measurements) for the 5″ x 8″ flex vent terminations – for use with a firestop or wall thimble.

Recommended Framed Opening Size

Vent Size| Framing Size
5″ x 8″| 11″ x 11″

1. Locate the unit in the framing, 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 (inside dimension).
   • Note: If installing termination on a siding-covered wall, a vinyl siding standoff or vinyl furring strips must be used to ensure that the termination is not recessed into the siding.
2. Level the fireplace and fasten it to the framing using nails or screws through the nailing strips.
3. Assemble the vent assembly by applying Mill-Pac to the inner flue collar of the termination and slipping the inner flex liner over it at least 1-3/8″ (35mm). Fasten with the 3 screws (drilling pilot holes will make this easier). Apply Mill-Pac to the outer flex pipe and slip it over the outer flue collar of the vent terminal at least 1-3/8″(35mm) and fasten with the 3 screws.
   • NOTE: Horizontal sections must be supported at intervals not exceeding 3 feet (0.9 meters). (Flame picture and performance will be affected by sags in the liner).
4. Separate the 2 halves of the wall thimble and securely fasten the one with the tabs to the outside wall making sure that the tabs are on top and bottom. Fasten the other thimble half to the inside wall. The thimble halves slip inside each other and can be adjusted for 2 x 4 or 2 x 6 walls.
5. Slip the assembled liner and termination assembly through the thimble making sure the termination cap faces up (there are markings on the cap that show which way is up). This will position the termination cap with a 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. (You may wish to cut the liner shorter to make it more workable.) Do not bend the liner more than 90o. The liners must slip over the collars a minimum of 1-3/8″.
7. Apply Mill-Pac over the fireplace inner flue collar and slip the inner flex liner down over it and attach with 3 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 to keep the water out.

• IMPORTANT: Do not locate the termination hood where excessive snow or ice buildup may occur.
• Be sure to check the vent termination area after snow falls, and clear to prevent accidental blockage of the venting system.
• When using snow blowers, make sure snow is not directed towards the vent termination area.
