C. Secure and Level the Appliance
WARNING! Risk of Fire! Prevent contact with:
•Sagging or loose insulation
•Insulation backing or plastic
•Framing and other combustible materials
Block openings into the chase to prevent entry of blown- in insulation. Make sure insulation and other materials are secured.
DO NOT notch the framing around the appliance standoffs.
Failure to maintain air space clearance may cause overheating and fire.
The diagram shows how to properly position, level, and se- cure the appliance (see Figure 9.12). Nailing tabs are pro- vided to secure the appliance to the framing members.
•Bend out nailing tabs on each side.
•Place the appliance into position.
•Keep nailing tabs flush with the framing.
•Level the appliance from side to side and front to back.
•Shim the appliance as necessary. It is acceptable to use wood shims underneath the appliance.
•Secure the appliance to the framing by using nails or screws through the nailing tabs.
•Secure the appliance to the floor by inserting two screws through the pilot holes at the bottom of the appliance.
