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 Draft Stops Chimney Height LOCATION OF FIREPLACE 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. Carefully select the proper location for heat circulation, aesthetics, chimney obstructions and clearance to side wall(s).
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. 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.

FRAMING SPECIFICATIONS Framing Dimensions (See Note) Header B A Fireplace Framing Note: When Framing With 6” Studs Header Must Be 17” (432mm) Higher. Use Security Chimney’s OR15 Offset/Return Elbow To Recess The Chimney Back 2 1/2” (64mm). Flat Frame Down To A False Header At (B). Maintain Required Clearance To Chimney At All Times.
Step 4. Fireplace should be secured to side framing members using the full length nailing tabs at the top and bottom of the fireplace front face. Use 8d nails (Figure 17 ). Step 6. Connect the 6" (102 mm) Class 0 air duct provided by installer, to the duct collar on the fireplace and secure with two (2) screws from the kit’s hardware package. CAUTION: ALLOW MINIMUM 1"* CHIMNEY AIR SPACE TO COMBUSTIBLE FRAMING MEMBERS THROUGHOUT VERTICAL OR OFFSET CHIMNEY INSTALLATION. Step 7.
Note: If there is a room above ceiling level, firestop spacer must be installed on the bottom side of the ceiling. If an attic is above ceiling level, firestop spacer must be installed on top side of ceiling joist (Figures 21 and 22 ). Room Above Room Above F8FS30 Firestop Spacer 1"* Min. Air Space 1"* Min. Air Space If the flue has been installed correctly, it will not separate when you test it. Also, the inner flue joint where each section is joined should be tight and flat without gaps (Figure 26 ).
Security's chimney sections do not need to be screwed together. Additional reinforcement is not necessary except in certain offset conditions (refer to page 14, Figure 39 ). Step 5. The height of vertical chimney pipe supported only by the fireplace must not exceed 30'. Chimney heights above 30' must be supported by a Model FTF8-S4 stabilizer installed at 30' intervals. Note: The Model FTF8-S4 adds 3" net effective height to the total chimney system.

Using a FTF8-CTDT Chase Termination: Refer to specific installation instructions included with the FTF8-CTDT chase termination for clearance and installation details. Using a FTF8-CT1 Chase Termination: Refer to specific installation instructions included with FTF8-CT1 chase terminations for clearance and installation details.
4. Determine amount of chimney height required by subtracting total combined height of all pre-selected components (fireplace and chimney components from total desired height.) Reference Vertical Elevation Chart and determine the number of chimney sections (quantity and length) required. Step 2. Use “Height of Chimney Only” column in The Vertical Elevation Chart to determine combinations of chimney used above return elbow to achieve desired heights.
OFFSET ELEVATION CHART A1 Return Elbow 20' Max. B1 Stabilizer 10' Max.
Measure height to the ceiling from the top of fireplace-dimension “B.” Use the appropriate Offset Elevation Chart to find dimension “A.” Mark point where you will drive your nail to show the center point for your offset ceiling cut. et Scr Eve ews r y Re Joi qu nt ired Pa st At 6' Joints Chimney Section Step 2.

THIS FIREPLACE IS NOT INTENDED TO BE USED AS A SUBSTITUTE FOR A FURNACE TO HEAT AN ENTIRE HOME. USE FOR SUPPLEMENTARY HEATING ONLY. Combustion Air Actuator Remove Locking Screw and “Pop” Actuator to the Left Before Initial Use Vent Free Appliances This unit has 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, when installed with unvented gas log sets.
THE KNOCKOUT IS ALWAYS REMOVED FROM INSIDE THE FIREPLACE. DO NOT REMOVE THE KNOCKOUT UNLESS YOU ARE INSTALLING A GAS LINE. If removal is attempted from the outer wrapper, side refractory damage may occur. With a medium-sized hammer, lightly tap the surface of the indentation. The refractory material is very thin in this area and is easily removed. Once a small hole has been made, continue tapping until you have reached sufficient diameter for the gas line to fit through.
If fireplace is installed diagonally across a 90° corner; no wall shields are required. Methods of Determining Hearth Extension and Wall Shield Equivalents “R value” = 1 = r x thickness of material used k To determine the thickness required for any material when either the k or r values are known: Alternative Hearth Extension and Wall Shield Materials Listed TM kM rM TL C = = = = A D Hearth Extension Dimensions A 16" B 35" C 8" D 51" k r TL Millboard .43 2.
