If a wall covering such as drywall is to be attached to the rear wall, then the dimension must be measured from the drywall surface. Note:Framing dimensions in Figures 4 - 9 are calculated for a nailing flange depth of..." (13 mm). Note:Framing dimensions in Figures 4 - 9 are calculated for a nailing flange depth of..." (13 mm).

Align with the three holes on each side of the appliance (see Figure 11). Figure 11 All units come complete from the factory with an installed hood. Ensure that the hood is installed. If required, position the hood in the open area above the appliance door covering the diverter baffles. Insert the tabs, on each end of the hood, into the bracket at each end. Bend the two tabs over to secure. Step 4. Position appliance into prepared framing, secure with 6d nails at the nailing flange along each side. Step 5. Connecting Gas Line – Make gas line connections. All codes require a shut-off valve mounted in the supply line. Figure 12illustrates two methods for connecting the gas supply. Installation methods and materials must be in compliance with local codes. NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE. The gas control valve is located in the lower control compartment. To access the valve open the lower control compartment door (Figure 13). The control valve has a ..." NPT thread inlet port and is fitted with a 3" (76 mm) long nipple, ..." NPT on both ends.
