23W415-1434 / 06.09.15ENIt is best to frame your appliance after it is positioned and the vent system is installed. Use the steel frame providedexcept when recessing into non-combustible material deeper than 1 1/2”.5.0 FRAMING! WARNINGRISK OF FIRE!IN ORDER TO AVOID THE POSSIBILITY OF EXPOSED INSULATION OR VAPOUR BARRIER COMINGIN CONTACT WITH THE APPLIANCE BODY, IT IS RECOMMENDED THAT THE WALLS OF THEAPPLIANCE ENCLOSURE BE “FINISHED” (IE: DRYWALL / SHEETROCK), AS YOU WOULD FINISHANY OTHER OUTSIDE WALL OF A HOME. THIS WILL ENSURE THAT CLEARANCE TOCOMBUSTIBLES IS MAINTAINED WITHIN THE CAVITY.DO NOT NOTCH THE FRAMING AROUND THE APPLIANCE STAND-OFFS. FAILURE TO MAINTAINAIR SPACE CLEARANCE MAY CAUSE OVER HEATING AND FIRE. PREVENT CONTACT WITHSAGGING OR LOOSE INSULATION OR FRAMING AND OTHER COMBUSTIBLE MATERIALS. BLOCKOPENING INTO THE CHASE TO PREVENT ENTRY OF BLOWN-IN INSULATION. MAKE SUREINSULATION AND OTHER MATERIALS ARE SECURED.WHEN CONSTRUCTING THE ENCLOSURE ALLOW FOR FINISHING MATERIAL THICKNESS TOMAINTAIN CLEARANCES. FRAMING OR FINISHING MATERIAL CLOSER THAN THE MINIMUMSLISTED MUST BE CONSTRUCTED ENTIRELY OF NON-COMBUSTIBLE MATERIALS. MATERIALSCONSISTING ENTIRELY OF STEEL, IRON, BRICK, TILE, CONCRETE, SLATE, GLASS OR PLASTERS,OR ANY COMBINATION THEREOF ARE SUITABLE. MATERIALS THAT ARE REPORTED AS PASSINGASTM E 136, STANDARD TEST METHOD FOR BEHAVIOUR OF MATERIALS IN A VERTICAL TUBEFURNACE AT 1382° F (750°C) AND UL763 SHALL BE CONSIDERED NON-COMBUSTIBLEMATERIALS.MINIMUM CLEARANCE TO COMBUSTIBLES MUST BE MAINTAINED OR A SERIOUS FIRE HAZARDCOULD RESULT.THE APPLIANCE REQUIRES A MINIMUM ENCLOSURE HEIGHT. MEASURE FROM THE APPLIANCEBASE.IF STEEL STUD FRAMING KITS WITH CEMENT BOARD ARE PROVIDED, OR SPECIFIED IN THEINSTALLATION INSTRUCTIONS. THEY MUST BE INSTALLED.FINISHING MUST BE DONE USING A NON-COMBUSTIBLE MATERIAL EXTENDING FROM THE TOPOF THE APPLIANCE SUCH AS NON-COMBUSTIBLE BOARD, CERAMIC TILE, MARBLE, ETC. DONOT USE WOOD OR DRYWALL.ANY FIRE RATED DRYWALL IS NOT ACCEPTABLE.71.1BMaintain these minimum clearances to combustibles from appliance and vent surfaces:Appliance framing:Use steel framing provided.Non- Combustible Appliance fi nishing:Front - 4 3/4" (121mm) to sides of appliance opening- 10" (254mm) above appliance openingCombustible Appliance finishing:- 70" (1778mm) from bottom of appliance to enclosure top- 2" (51mm) to top of vent pipe*- 1" (25mm) to sides and bottom of vent pipe**HORIZONTAL VENT SECTIONS: A minimum clearance of 2" (51mm) to the top and 1" (25mm) to the sides andbottom of the vent pipe on all horizontal runs to combustibles is required.*VERTICAL VENT SECTIONS: A minimum of 1" (25mm) all around the vent pipe on all vertical runs tocombustibles is required except for clearances in appliance enclosures. Use firestop spacer W500-0096 (notsupplied).Ceiling heightis minimum 24"(610mm) from thetop of the applianceopening.
