•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.
NOTICE: Failure to ensure that the fireplace opening is square may result in the decorative front not fitting properly.
The diagram shows how to properly position, level, and secure the appliance (see Figure 9.1). Nailing tabs are pro- vided to secure the appliance to the framing members.
1.Venting - refer to Vent Clearances and Framing (Section 8) for hole location.
2.Place the appliance into position, making sure to maintain proper clearance to combustibles.
3.Level the appliance from side to side and front to back. It is acceptable to use wood shims under the appliance.
4.Fasten the appliance to the floor using the pilot holes located at the bottom of the appliance.

6.Using a framing square, make sure that the sides of the appliance are square to the bottom as shown in Figure 9.2.
