Mantels

The height that a combustible mantel is fitted above the fireplace is dependent on the depth of the mantel. This also applies to the distance between the mantel leg (if fitted) and the fireplace.

For the correct mounting height and widths refer to Figure and the Mantel Chart below.

Noncombustible mantels and legs may be installed at any height and width around the appliance.

When using paint or lacquer to finish the mantel, such paint or lacquer must be heat resistant to prevent discoloration.

Hearth

A hearth is not mandatory but is recommended for aesthetic purposes. We recommend a noncombustible hearth which projects out 12” (305mm) 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

1.Choose the unit location.

2.Place the unit into position and secure it to the floor with 1¹⁄₂” (38 mm) screws, or nails. The holes to secure the unit to the floor are located just behind the access door grille on the left and right side of the unit.

3.Frame in the fireplace with a header across the top. It is important to allow for the finished wall face when setting the depth of the frame.

4.Drywall (sheetrock) or wood material may be placed with a zero clearance to the top edges of the appli-
