8 I1200 Regency Wood InsertINSTALLATIONClearance diagram for installationsSide and Top facing is a maximum of 1.5" thick.Floor protection must non-combustible, insulativematerial with an R value of 1.1 or greater.* If the hearth extension is flush with the floor (F)it must extend 19.5" in front of the body face(E).Note: Hearth Extension Width (G) is meas-ured from edge of fuel door to side ofhearth.** A non-combustible mantel may be installedat a lower height if the framing is made ofmetal studs covered with a non-combustibleboard.MASONRY AND FACTORY BUILT FIREPLACE CLEARANCESThe minimum required clearances to combustible materials when installed into a masonry or factory built fireplace are listed below.Adjacent Mantle** Top Side Minimum Minimum MinimumUnit Side Wall (to Top) Facing Facing Hearth Hearth Hearth Side(to Side) (to Top) (to Side) Extension* Thickness* ExtensionA B C D E F GI1200S 15" (381mm) 20" (508mm) 14" (356mm) 7.375"(187mm) 16" (406mm) 1.5" (38mm) 8" (203mm)HOW TO DETERMINE IF ALTERNATEFLOOR PROTECTION MATERIALS ARE ACCEPTABLEThe specified floor protector should be 3/8"(18mm) thick material with a K - factor of0.84.The proposed alternative is 4" (100mm) brickwith a C-factor of 1.25 over 1/8" (3mm) mineralboard with a K-factor of 0.29.Step (a):Use formula above to convert specificationto R-value.R = 1/k x T = 1/0.84 x .75 = 0.893.Step (b):Calculate R of proposed system.4" brick of C = 1.25, thereforeRbrick = 1/C = 1/1.25 = 0.801/8" mineral board of k = 0.29, thereforeRmin.bd. = 1/0.29 x 0.125 = 0.431Total R = Rbrick + Rmineral board =0.8 + 0.431 = 1.231.Step (c):Compare proposed system R of 1.231 tospecified R of 0.893. Since proposed systemR is greater than required, the system isacceptable.DEFINITIONSThermal Conductance:C = Btu = W(hr)(ft2 )( oF) (m2) )(K)Thermal Conductivity:k = (Btu)(inch) = W = Btu(hr)(ft3 )( o F) (m)(K) (hr)(ft)(o F)Thermal Resistance:R = (ft2 )(hr)( o F) = (m2 )(K)Btu WFloor ProtectionPlease check to ensure that your floor protection and hearth will meet the standards forclearance to combustibles. Your hearth extension must be made from a non-combustiblematerial.Thermal floor protection is not required if the unit israised 3.5" minimum (measured from the bottom ofthe stove). However, standard ember floor protectionis required. It will need to be a non-combustible mate-rial that covers 16" (406 mm) in the US and 18" (450mm) in Canada to the front of the unit and 8" (200mm) to the sides.If the unit is not raised, thermal floor protection requiredis 18" (450 mm) in the US and Canada.
