Fireplace Installation Framing selecting location To determine the safest and most efficient location for the fireplace, you must take into consideration the following guidelines: 1. The location must allow for proper clearances (see Figures 1 and 2). 2. Consider a location where the fireplace will not be affected by drafts, air conditioning ducts, windows or doors. 3. A location that avoids the cutting of joists or roof rafters will make installation easier. 4.
Fireplace Installation Mantels Continued Hearth Extension A hearth extension projecting a minimum of 20" in front of and a minimum of 12" beyond each side of the fireplace opening is required to protect combustible floor construction in front of the fireplace. Fabricate a hearth extension using a material which meets the following specifications: a layer of noncombustible, inorganic material having a thermal conductivity of K=0.84 BTU IN/FT, HR. F (or less) at 1" thick.
Venting Installation PART NO. Optional Outside air Kit (Model ak4/ak4f) The installation of an outside air kit should be performed during the rough framing of the fireplace due to the nature of it's location. Outside combustion air is accessed through a vented crawl space (AK4F) or through a sidewall (AK4). CAUTION: Combustion air inlet ducts shall not terminate in attic space. Secure to Collars with Metal Tape, Screws or Straps (Min.
Venting Installation Continued Using ELBOW offsets (30E-12DM) 1. To achieve desired offset, you may install combinations of 12", 18", 24", 36" and 48" length of double wall pipe (see offset chart and Figure 7). OFFSET A RISE B 12" CHIMNEY LENGTH 18" 24" 36" 48" 2. Chimney weight above offset rests on return elbow. Straps must be securely nailed to rafters or joists (see Figure 8, details a and b). 3. Maximum length of pipe between supports (return elbow or 12S-12DM) is 6' of angle run.
Venting Installation Continued Screws B A Figure 9 - Elbow Offset Penetrating the roof To maintain a 1" (GM36) or 2" (GM42/GM50) clearance to the pipe on a roof with a pitch, a rectangular opening must be cut. 1. Determine the center point through which the pipe will penetrate the roof. 2. Determine the center point of the roof. Pitch is the distance the roof drops over a given span, usually 12". A 6/12 pitch means that the roof drops 6" for each 12" one measure horizontally down from the roof rafters.
Venting Installation Continued 4. Remove the shingles around the opening measured. Cut out this section. 5. Add the next sections of the pipe until the end penetrates the roof line. Check to see that the proper clearances are maintained. Extend chimney by adding sections of double wall pipe until pipe is minimum of 30" above the highest point of the roof cutout. Termination and chimney must extend a minimum of 36" above the highest point where it passes through the roof.
Venting Installation Continued Chase installations Instructions for chase installations are included with the chase style termination chosen. In a multiple chase installation, be sure to provide adequate distance between terminations to prevent smoke spillage from one termination to another. We suggest that terminations be separated at least 24" center to center and stacked at a vertical height difference of 18" (see Figure 16).
Optional Gas Line Installation Continued CAUTION: All gas piping and connections must be tested for leaks after the installation is completed. After ensuring that the gas valve is on, apply soap and water solution to all connections and joints. Bubbles forming show a leak. Correct all leaks at once. DO NOT USE AN OPEN FLAME FOR LEAK TESTING AND DO NOT OPERATE ANY APPLIANCE IF A LEAK IS DETECTED. LEAK TESTING SHOULD BE DONE BY A QUALIFIED SERVICE PERSON.
Brick Installation Installing Brick "S" Use brick “S” if an optional gas line is installed. Mount brick “S” as shown in Figure 21. It is important that the knockout hole is in its proper location. The knockout hole on brick “S” should align with the hole on the brick housing. Installation of brick should be done after the fireplace is placed in a permanent location. The brick housing panels are already installed in the firebox. Each housing is stamped with a letter (full size bricks are not stamped).
