PRECAUTIONS Note: These fireplace systems are not difficult to install. However, in the interest of safety, it is recommended that the installer be a qualified or certified “tradesman” familiar with commonly accepted fireplace installation and safety techniques as well as prevailing local codes.
Insulate Joists Same As Ceiling Note: Local codes may not require firestopping at the ceiling levels for outside chase installations. However, it is recommended for safety and the reduction of heat loss. 19" (483mm) 19" (483mm) Chimney Height Damper Closed Lintel The total height of your completed fireplace system from the surface the fireplace rests on to the chimney top must not exceed 80' (24.4) and must also meet minimum height requirements. Refer to the minimum system height chart.

ASSEMBLY STEPS Note: The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence. 1. Position firebox prior to framing or into prepared framing.
The safety strips should extend from front of the fireplace at least 1-1/2" and should extend to be at least flush with the sides. In the event a wooden support is used to elevate the fireplace above the floor, a “Z” type safety strip should be fabricated and used to protect the front surface of the wood support as well as the floor beneath the hearth extension (Figures 8 and 9 ). The safety strips should be tacked down to prevent possible movement.
Note: The framed depth, 25-1/2" (648 mm) from a framed wall, must always be measured from a finished surface. If a wall covering such as drywall is to be attached to the rear wall, then the framed depth must be measured from the drywall surface. It is important that this dimension be exact. If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.
Step 4. The fireplace should be anchored to the floor. Bend down the four (4) anchor tabs located at the base of the fireplace and secure to the floor with 8d nails (Figure 17 ). Anchor Tab Step 7. Connect the 4" (102 mm) Class 0 air duct provided, to the collar on the chimney collar enclosure with the screws provided in the kit’s hardware package. Step 8. Route the Class 0 air duct out the back or side wall, up through the ceiling or floor joists to an outside wall.
Step 3. Position the appropriate firestop spacer at the ceiling and nail temporarily with two (2) 8d nails. Use a flat firestop spacer, Model F10FS-2, for the FTF10 system if chimney penetrates vertically. If the chimney penetrates through the ceiling at a 30° angle (offset chimney) then use a 30° firestop spacer, Model F10FS30-2. Use one nail on opposite sides of the firestop to hold in position.
Note: Assemble one component of chimney at a time (inner section first; then outer section last) before preceding with the next complete section. Continue to assemble the chimney up through framed opening. Assemble just enough to penetrate the roof flashing openings (Figure 28 ). Always maintain 2" minimum air space to combustible materials and always check each chimney joint (inner and outer) to ensure proper engagement.
Step 10. Installing a FTF10 CTDTM Round Termination: 1. Hold the FTF10 CTDTM over the top of the last chimney section installed (Figure 34 ). 2. Center the inner slip section into inner flue pipe and slip down. 20" (508mm) Note: It is recommended that all exterior exposed metal fireplace components; such as terminations, flashings, storm collars and/or flue be painted with a premium quality, high temperature, rust preventative paint designed for metal.

Determine amount of chimney height required by subtracting total combined height of all pre-selected components (fireplace and chimney components from total desired height.

Offset Elbow Assembly Combustion Air Kits Forced Air Kit Offset elbows install the same as chimney sections. First, snap the inner section INTO the preceding inner section of flue. Check connection by pulling up slightly to ensure a tight fit. Next, the outer sections snap lock OVER the preceding outer section of chimney. Again, check outer section by pulling up slightly to ensure proper connection is made. You may use the combustion air kit, Model FOAK-4 or FOAK-4LD, with the LBR/LBC Series fireplaces.
Vent Free Appliances These units have been tested and approved to ANSI/IAS/AGA Z21.11.2 for use with unvented gas appliances and complies with the standard for Factory-Built fireplaces, UL 127. The unit has been tested for use with any unvented gas log sets having a maximum rating of 40,000 BTU. The minimum mantle configurations are outlined in Figures 43 and 44.

Note: Any noncombustible material whose k value is less than .84 or whose r value is more than 1.19 is acceptable. If the fireplace is installed on a combustible floor, use the metal safety strips (provided) on the floor extending half under the fireplace and half under the hearth extension (refer to Figures 6 & 7). A wall shield is required where a continuous perpendicular side wall is within 12" of the fireplace opening (Figure 46 ).
Combustible materials may project beyond the sides of the fireplace opening as long as they are kept within the shaded area, as illustrated in Figure 49 for LBR models and Figure 50 for LBC models.
