Initial Installation
QUALIFIED INSTALLERS ONLY
Even though the DV36 can be installed at floor level without a hearth, there are a few options with raised fireplaces: raised with a floor level hearth (Figures 19), raised with a raised hearth (Figures 20), or raised with no hearth (Figures 21). If the fireplace is raised, it cannot be placed within 37 inches (1.04 m) of the ceiling. When installing a raised fireplace, it is imperative that the support stand is strong enough to hold the weight of the fireplace and venting.

MANTEL CLEARANCES:
It is not necessary to install a mantel, but if one is desired it is important to follow the guidelines. Note: Louvers have different mantel clearances than when fascia or insets are installed.
