! WARNING• Risk of fire!• In order to avoid the possibility of exposed insulation or vapour barrier coming in contact with the appliancebody, it is recommended that the walls of the appliance enclosure be “finished” (i.e. drywall / sheetrock),as you would finish any other outside wall of a home. This will ensure that clearance to combustibles ismaintained within the cavity.• Do not notch the framing around the appliance stand offs. Failure to maintain air space clearance may causeover heating and fire. Prevent contact with sagging or loose insulation or framing and other combustiblematerials. Block opening into the chase to prevent entry of blown-in insulation. Make sure insulation andother materials are secured.• When constructing the enclosure, allow for fi nishing material thickness to maintain clearances. Framing orfi nishing material closer than the minimums listed must be constructed entirely of non-combustible materials.Materials consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or any combinationthereof are suitable. Materials that are reported as passing ASTM E136, standard test method for behaviourof materials in a vertical tube furnace at 1382ºF (750ºC) and UL763 shall be considered non-combustiblematerials.• Minimum clearance to combusibles must be maintained or a serious fire hazard could result.• The appliance requires a minimum enclosure height. Measure from the appliance base.• If steel stud framing kits with cement board are provided, or specified in the installation instructions, theymust be installed.• If specified in the installation instruction, finishing must be done using a non-combustible board, ceramic tile,marble, etc. Do NOT use wood or drywall. Any fire rated drywall is not acceptable.When using optional finishing accessories, the framing dimensions and finishing materials may differ fromwhat is outlined in the section below; refer to the leaflet instructions supplied in the accessory kit for specificframing and finishing specifications.44.1note:4.0 framingIt is recommended that the walls of the appliance enclosure be finished. This would ensure that clearance tocombustibles is maintained within the cavity. It is best to frame your appliance after it is positioned. Use 2x4’s andframe to local building codes.4.1 gas inlet locationsThere are five gas inlet locations on the ventless firebox enclosure: one on each side of the appliance, two atthe rear, and one on the bottom. Use the following illustrations to identify the preferred inlet and then remove thecorresponding knock out.35 9/16"904mm7 3/16"183mm15"381mm20 3/16"513mm13 5/16"338mm7 3/16"183mm42"1066mm21 1/16"534mm15 5/8"397mmBOTTOM VIEWFRONT VIEW RIGHT SIDE VIEW TOP VIEW35 9/16"904mm7 3/16"183mm15"381mm20 3/16"513mm13 5/16"338mm7 3/16"183mm42"1066mm21 1/16"534mm15 5/8"397mmBOTTOM VIEWFRONT VIEW RIGHT SIDE VIEW TOP VIEW35 9/16"904mm7 3/16"183mm15"381mm20 3/16"513mm13 5/16"338mm7 3/16"183mm42"1066mm21 1/16"534mm15 5/8"397mmBOTTOM VIEWFRONT VIEW RIGHT SIDE VIEW TOP VIEWENW415-1796 / A / 05.17.1811
