If the fireplace is to be installed on a raised platform,a Z-type ember protector (not supplied) must be fabricated tofit your required platform height. The ember protector shouldextend under the fireplace a minimum of 1 - 1/2”. The emberprotector should be made of galvanized sheet metal (28-gageminimum) to prevent corrosion.STEP 6: Using screws or nails, secure the fireplace to theframing through flanges located on the sides of the fireplace.HEARTH EXTENSIONA hearth extension projecting a minimum of 20” in front ofand a minimum of 12” beyond each side of the fireplaceopening is required to protect combustible floor constructionin front of the fireplace. Fabricate a hearth extension using amaterial which meets the following specifications: a layer ofnon-combustible, inorganic material having a thermalconductivity of K = 0.84 BTU IN/FT. HR. F (or less) at 1”thick. For example, if the material selected has a K factor of0.25, such as glass fiber, the following formula would apply:Thermal conductivity “K” of materials can be obtained fromthe manufacturer or supplier of the non-combustible material.If the hearth extension is to be covered, use non-combustiblematerial such as tile, slate, brick, concrete, metal, glass,marble, stone etc. Provide a means to prevent the hearthextension from shifting and seal gap between the fireplaceframe and hearth extension with a non-combustible material(see figure 3).OPTIONAL OUTSIDE AIR KIT (MODEL AK4 / AK4F)The installation of an outside air kit should be performedduring the rough framing of the fireplace due to the nature ofits location. Outside combustion air is accessed through avented crawl space (AK4F) or through a sidewall (AK4). Seepage 10, figure 23 for instructions on how to operate the airkit.WARNING Hearth extension is to be installed onlyas illustrated.Figure 4 OUTSIDE AIR KIT0.25 x 1.0” = 0.30 thickness required0.84Figure 2 CORNER INSTALLATIONFigure 1 FRAMING DIMENSIONFigure 3 HEARTH EXTENSION
