H. Moisture Resistance
This outdoor appliance will shed moderate
amounts of water, but is not waterproof. This
appliance must be enclosed or covered with
combustible and non-combustible finish material
per framing dimension requirements and all joints
sealed to prevent water infiltration.
A moisture membrane material can be taped 2"
from the top of the rain shield; 2" on each side
from top to bottom. The entire bottom of the unit
can be used to tie in a water membrane material,
however the bottom does have an incorporated
drain pan with the front edge of the bottom edge
being the point of moisture exiting the unit. This
must be taken into consideration when sealing
unit. As shown in Figures 3.7, 3.8 and 3.9.
The firebox will not perform as an exterior wall.
Moisture penetration must be considered for
construction that places the appliance in structure
walls or on moisture sensitive surfaces.
When installed on exterior walls: Hearth &
Home Technologies recommends that the 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 1/8 in. to 1/4 in.
per foot. The appliance can be shimmed level.
Water Drainage: The Courtyard is designed to
operate outdoors, experiencing rain and other
sources of moisture that will enter the firebox.
The Courtyard inner firebox bottom is designed
to drain water out of the unit and the lower edge
should not be covered over, allowing moisture to
exit from the inner area.
Some amount of water may still penetrate into the
inner firebox cavity. The bottom of the Courtyard
is designed with an integrated drain pan. The
bottom of the unit slopes forward, forcing moisture
toward the slot located under the front edge. The
L bracket secured under the slot can be used
to attach water membrane material in a manner
consistent with regional practices.
