• Travis Industries, Inc. grants no warranty, implied or stated, for the installation or maintenance of your heater, and assumes no responsibility for any consequential damage(s).

Operating Warnings

• WARNING: THE FIREPLACE SHOULD BE OPERATED ONLY WITH DOORS FULLY OPEN OR DOORS FULLY CLOSED. IF DOORS ARE LEFT PARTLY OPEN, GAS AND FLAME MAY BE DRAWN OUT OF THE FIREPLACE OPENING, CREATING RISKS OF BOTH FIRE AND SMOKE.

• Creosote – Formation, and Need for Removal

• When wood is burned slowly it produces tar and other organic vapors which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely hot fire.

• The chimney shall be inspected at least twice a year during the heating season to determine when a creosote buildup has occurred.
  When creosote has accumulated it shall be removed to reduce the risk of a chimney fire.

• Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in this fireplace. Keep all such liquids well away from the fireplace while it is in use.

• Disposal of Ashes

• Ashes should be placed in a metal container with a tight-fitting lid. These closed containers of ashes should be placed on a noncombustible floor or the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

• A fireplace insert shall not be installed in a factory-built fireplace unless tested with the fireplace.

• Proposition 65 Warning: Fuels used in gas, woodburning or oil-fired appliances, and the products of combustion of such fuels, contain chemicals known to the State of California to cause cancer, birth defects, and other reproductive harm. California Health & Safety Code Sec. 25249.6

Installation Recommendations for Cold Environments

• If you live in the area depicted in black in the illustration to the right (or in Canada), we recommend the following steps be taken to minimize cold air infiltration.

Insulated Chimney is Strongly Recommended

• The insulated chimney does not require cooling ducts and is therefore preferred for cold environments. This is the number one method for improving cold weather performance.

Use the “P” Trap & Insulated Duct in the Cooling Duct.

• If using an air-cooled chimney, we recommend insulating the intake duct and putting in a “P” trap to help prevent air circulation when the fireplace is not in use. A typical “P” trap design is shown in the illustration to the right.

Use Bi-Metallic Damper with Air-Cooled Chimney

• If using air-cooled chimney, we recommend the use of the bi-metallic damper. This component (part # 250-01741) is an 18” section of DuraVent pipe that is installed at the top of the chimney, directly below the cap. It has a heat-activated damper that helps reduce cold air from entering the cooling ducts while the fireplace is not in operation.

Use Outside Air “P” Trap and Insulated Duct

• We recommend putting in a “P” trap in the outside air duct (used to supply air to the firebox) to prevent air circulation when the fireplace is not in use. A typical “P” trap design is shown in the illustration above. In addition, you should insulate the outside air duct to help reduce air circulation when the fireplace is not in use.

Daily Requirements for Homeowners

• HUMIDITY – Make sure the humidistat is set correctly. The chart below details the correct setting for the temperature you are experiencing outdoors.

Note: If using a humidifier, let the homeowner know that it should be shut off or turned to a lower setting to eliminate condensation on the front of the fireplace.

OTHER ITEMS

• Make sure the bypass is shut when the fireplace is not in use.
• Slide the air control fully closed when the fireplace is not in use.
• Minimize the use of exhaust fans in the home when the fireplace is not in use.

Fireplace Placement Requirements

Clearances to Fireplace

• Sidewalls to the front of the fireplace must be 45” (1143mm) from the centerline of the fireplace (see “a” in the illustration below).
• Any combustible (bookshelf, column, etc.) that protrudes less than 7” (178 mm) from the front of the fireplace must be placed a minimum of 24-3/8” (620 mm) from the centerline of the fireplace. If this combustible protrudes farther, it must meet the sidewall clearance (see “b” and “c” in the illustration below).
• The fireplace requires a ½” (13mm) clearance to the back and sides (stand-offs are pre-installed to provide this clearance). Do not place insulation or other material in this area. Drywall or other combustibles must maintain a ½” clearance to the sides of the fireplace (see “d” in the illustration above).
• The fireplace should be located such that no doors, drapes, furniture, or other combustibles can be placed close or swing closer than the minimum 48″ clearance. Due to the high heat output of this fireplace, choose a location away from high-traffic areas.

Fireplace Placement

• The fireplace must be secured to the floor and/or framing (see “nailing brackets” in the illustration below).
• The fireplace must be placed directly on a wood or non-combustible surface (not on linoleum or carpet).
• The fireplace must be installed on a level surface capable of supporting the fireplace and chimney.
• Place the ember strip included with the fireplace below the front edge of the fireplace (see illustration below). This prevents embers from sliding between the fireplace and the hearth.
• The Fireplace must be placed so the vents below and above the glass do not become blocked.

Fireplace Framing

Minimum Framing Dimensions

• Minimum framing dimensions are shown in the illustration to the right. Do not build into the enclosure.
• The enclosure over the fireplace must be a minimum of 81” above the base of the fireplace.

Framing Dimensions at 45°

• Typical framing dimensions for 45° installation are shown below. Additional space may be required for vent and outside air installation.
• (a) 61-3/4” (1569mm)
• (b) 22-1/2” (572mm)
• (c) 22-1/2” (572mm)

Raised Fireplaces

• The fireplace (and hearth, if desired) may be placed on a platform designed to support the fireplace and vent (approximately 600 lbs.). See the illustration below.
• The ceiling in front of the fireplace must be a minimum of 83” from the base of the fireplace.

Approved Chimney

The entire chimney system must be installed to meet all local requirements as well as those requirements listed by the chimney manufacturer. Depending on the manufacturer and where the chimney is to be installed, chimney supports, roof braces, radiation shields, attic insulation shields, attic enclosures, spark arrestors, locking bands, etcetera, may be required as part of the chimney system. The manufacturer’s installation instructions, which are reviewed by the listing agency, specify when and where each of these components must be used. Follow the manufacturer’s instructions for the use of flashing and an adjustable storm collar at the roof line to prevent water from entering the house. Manufacturers require that chimneys extending beyond a certain height above the roof (typically above 5′) must be braced.

Part Numbers (available through Travis Industries

Anchor Plate Installation

• The air-cooled chimney requires an anchor plate that includes a cooling duct inlet. Attach the anchor plate to the top of the fireplace with the four included sheet-metal screws (see illustration below). The cooling duct inlet can be directed in any direction (typically it is directed to the right rear).
• Seal the fireplace connection with high-temperature silicone.
• Seal the flue liner with furnace cement.

Cooling Duct Installation

• WARNING: The cooling duct provides cooling air for the chimney system. Failure to correctly install the cooling duct will lead to an extremely dangerous installation and possibly a fire.
• The 6” diameter cooling duct routes air from outside the structure to the cooling air collar on the starter section. Do not draw air from a garage or other enclosed, unventilated, area.
• The maximum distance of the cooling duct is 30’. When routing the duct, use a minimum of bends and keep the bend radius as large as possible. The maximum bends for the duct is 540° (six 90°bends). The cooling duct must maintain a 2” clearance to the chimney. The cooling duct must be non-combustible.
• The Cooling Duct Kit (98900108) includes 30’ of cooling duct, collar, and external termination. Attach the external termination to the structure (use storm collar if needed) with the opening facing downwards (to prevent water or other material from entering). Secure the cooling duct to the collar and external termination using high-temperature aluminum tape and/or sheet metal screws.
• Locate the duct termination so it does not become blocked by snow, vegetation, or other material.
• The duct termination must be a minimum of 5’ below the chimney termination. In addition, the intake must be 10’ away from the chimney termination to prevent flue products from entering (measure the distance air must travel between the two terminations).
• The cooling air duct termination may be installed to draw air from a ventilated crawl space or attic if approved by local building codes. NOTE: certain codes require a fire curtain damper in these cases.
• The cooling air duct termination must be flashed and sealed to meet local building code requirements.

Air Cooled Chimney – Clearances to Combustibles

• WARNING: Follow the clearances listed below – do not follow the clearances listed in the chimney instructions.
• Maintain a 2″ clearance from the chimney to combustibles – see illustration below.
• Air Cooled Chimney – Installation and System Height
• Minimum 15′ system height (measured from the base of the fireplace)
• Maximum 35′ system height (measured from the base of the fireplace)

MINIMUM HEIGHT WITH OFFSETS

• One Pair (2) Offsets The minimum system height is 17’.
• Two Pairs (4) Offsets The minimum chimney height is 19’.
• NOTE: In problematic locations (areas with high wind or at altitude, etc.) additional chimney height above the specified minimum may be necessary to reduce wind-induced down drafts, back puffing, or smoke spillage. By adding an additional chimney, the fireplace will have an increased draft and encounter fewer negative operating characteristics.

Air Cool Chimney – Offset Requirements (30° Elbows)

• Offsets (using a pair of 30° elbows) may be used to redirect the chimney. Typically this is done to avoid structures, align the pipe with framing, or gain clearance to combustibles (see illustration below).
• A maximum of four 30° elbows may be used.
• Each elbow must be used in conjunction with a return elbow (so the chimney returns to a vertical direction)
• If using a single offset (two 30° elbows) a maximum of 8′ of inclined chimney may be used between elbows.
• If using two offsets (four 30° elbows) a maximum of 4′ of inclined chimney may be used between each set of elbows.
• For every 6′ of inclined chimney, a flue support is required – follow the chimney manufacturer’s instructions for supporting the chimney.
• Elbows may be used directly off the top of the fireplace.

Firestops

• Whenever the chimney penetrates a floor or ceiling a firestop is required on the bottom side of the floor joists (see illustration below).
• When passing through an attic the firestop must be placed on the attic side of the joists
• When the chimney passes through a living space it must be totally enclosed (maintain the minimum 2″ clearance to combustibles)
• The space between frames that hold the firestop in place should be measured as follows: Space Between Frames = 16”

• Once the fireplace is in place, with the hearth and facing complete, the fireplace may be finalized following the directions below.
• Install the firebrick as shown below.
• Place the baffle in position (see pictures below). Make sure it is pushed back so the tabs inside the firebox inserted into the slots on the baffle.
• Replace the log stop.
• Attach the face (see instructions included with the face).

Verify Door Operation

• Open the door handle and swing the door shut. Press down on the handle to lock the door in place (take care to not pinch your hand between the handle and door frame).
• The door may be tight the first time it is closed. This is because the gasket is new and has not compressed. We suggest opening and closing the door several times to help compress the gasket.
