Framing and Finishing

Check appliance to make sure it is levelled
and properly positioned.

The appliance should only be mounted on the following sur-
faces:

• A flat combustible (burnable) surface.

• A raised wooden platform.

• A concrete block or other solid object

placed beneath each of the four corners

of the appliance.

To mount the appliance:
1. Choose unit location.
2. Four (4) nailing flanges are supplied with the fireplace

(found on the fireplace hearth). To level the box and secure
it firmly in place, remove the nailing flanges from the hearth
and install at the sides of the fireplace as shown in Figure 6.
