:
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.

Figure 21. Raised Fireplace with no Hearth
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.
