Moisture Resistance

This outdoor fireplace will shed moderate amounts of
water, but is not waterproof. Water and condensing wa-
ter vapor may enter the chase under certain conditions.
The fireplace will not perform as an exterior wall. Mois-
ture penetration must be considered for construction
that places the fireplace in structure walls or on mois-
ture sensitive surfaces.
When installed on exterior walls: CFM Corporation
recommends the fireplace chase be constructed outside
the structure's weather envelope. Where the platform
meets the wall, use a flashing detail similar to that
required for attached decks. Chase platforms, including
hearths should slope away from the structure at 1/4 in
per foot. The fireplace can be shimmed level.
When installed on surfaces where water may collect or
cause damage: CFM Corporation recommends a slope
of 1/8 in to 1/4 in per foot towards the drain port sug-
gested. The fireplace can be shimmed level.
Hearths should slope away from the front of the fire-
place and chase at 1/8 in to 1/4 in per foot. Metal safety
strips must be on top of any combustible hearth materi-
als used for moisture management.

Mantels

WARNING: A 4" hood must be used if a
mantel is to be installed.
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
Figures 3a and 3b
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.
