INSULATION OR VAPOR BARRIERS, IF USED, MUST FIRST BE COVERED WITH GYPSUM BOARD, PLYWOOD, PARTICLE BOARD OR OTHER MATERIAL TO ASSURE INSULATION AND VAPOR BARRIERS REMAIN IN PLACE. WARNING: DO NOT PACK OR FILL RE- QUIRED AIR SPACES WITH INSULATION OR OTHER MATERIAL. NO MATERIAL IS ALLOWED IN THESE AREAS.

INSULATION OR VAPOR BARRIERS, IF USED, MUST FIRST BE COVERED WITH GYPSUM BOARD, PLYWOOD, PARTICLE BOARD OR OTHER MATERIAL TO ASSURE INSULATION AND VAPOR BARRIERS REMAIN IN PLACE. WARNING: DO NOT PACK OR FILL RE- QUIRED AIR SPACES WITH INSULATION OR OTHER MATERIAL. NO MATERIAL IS ALLOWED IN THESE AREAS. Note: Do not insulate the chase cavity with blown or fill type insulation materials. 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. Chimney Height The total height of your completed fireplace system from the surface the fireplace rests on to the chimney top must not exceed 60' and must also meet minimum height requirements. Refer to the minimum system height chart. Minimum System Height Security's FTF8 Pipe Vertical Installation 15' 0" One Offsets 15' 0" Two Offsets 25' 0" Chase Enclosure A chase is a vertical box-like structure constructed to surround the fireplace and chimney. Refer to Figure 2 for a typical chase configuration. As with all chimney installations, avoid overhead obstructions such as trees, power lines, etc. A chase should be constructed and insulated just like any outside wall. In a cold climate, we recommend the base of the chase should also be insulated between the solid continuous floor beneath the fireplace and the chase bottom. Chase insulation in a cold climate installation is not required for safety. ASSEMBLY OUTLINE Before You Start Check your inventory list to be sure you have all the necessary parts supplied in good usable condition. Check also for any concealed damage. Check the operation of the damper. The damper is controlled through the use of a control lever located within the firebox opening at the top center in front of the firebox lintel (Figure 3). The control lever snaps into place at either extreme of its range of motion. When locked in position all the way to the right, the damper is open. When locked in position all the way to the left, the damper is closed. Figure 3 DamperClosed Damper Open Lintel Combustion Air Actuator NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. LOCATION OF FIREPLACE Carefully select the proper location for heat circulation, aesthetics, chimney obstructions and clearance to side wall(s). With proper pre- planning, a slight adjustment of a few inches can save considerable time and expense later during construction and assembly. Hearth Hearth OptionalOutside Chase Figure 4 Carefully consider the position of the fireplace opening with respect to the location of adjacent or nearby stairwells, bath or kitchen exhaust fans and/or return air registers for forced air furnaces/air conditioners that could cause a smoking fireplace condition if the house is tightly insulated. When locating the fireplace, consideration must be given to combustibles and final finishing. See Figure 5and confine the final location of combustible finish materials to the "Safe Zone". DO NOT permanently place furniture or other items such as decorative pillows within 60" of the fireplace front face.

Position firebox prior to framing or into prepared framing. 2. Install the chimney system. 3. Connect house wiring to the fireplace for later attachment of optional blower. 4. Install optional outside combustion air kit. 5. Plumb gas line if a decorative gas appliance will be used. (Gas connections should only be performed by an experienced, licensed/certified tradesman.) 6. Complete the installation, finish wall material, surround and hearth extension to your individual taste. 7. Assemble and attach optional glass door assembly. Study the three dimensional illustration (Figure 1) to get a general idea of each element of your fireplace system. PRE-INSTALLATION NOTES The fireplace may be installed directly on a combustible floor or raised on a platform of an appropriate height. Do not place fireplace on carpeting, vinyl or other soft floor coverings. It may, however, be placed on flat wood, plywood, particle board or other hard surfaces. Be sure fireplace rests on a solid continuous floor or platform with appropriate framing for support and so that no cold ...
