Hearth
A hearth is not mandatory but is recommended for aesthetic purposes. We recommend a noncombustible hearth which projects out 12” (305 mm) or more from the front of the fireplace.
Cold climate installation recommendation: When installing this unit against a non- insulated exterior wall or chase, it is 
mandatory that the outer walls be insulated to conform to applicable insulation codes.
Framing and Finishing
Check fireplace to make sure it is levelled and properly positioned.
NOTE: If the optional Metro Face Kit (DVBR36 only) is to be installed, the fireplace may be placed on a 4” (102 mm) raised platform. Raising the fireplace will give the best aestethic appearance but is not required.
To mount the appliance:
1.Choose the location.
2.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 5.

Final Finishing
