Framing and Clearances
A. Selecting Fireplace Location
This outdoor fireplace will shed moderate amounts of water,
but is not waterproof. Water and condensing water vapor
may enter the chase under certain conditions.
The fireplace will not perform as an exterior wall. Moisture
penetration must be considered for construction that places
the fireplace against structure walls or on moisture sensitive
surfaces.
• Exterior Walls (see Figure 3.1)
Hearth & Home Technologies recommends that 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 1/8 in. to 1/4 in. per foot. The fireplace
can be shimmed level. Build the outside enclosure out of
standard building materials, being careful to maintain the
minimum air clearances specified in these installation
instructions.
Fire Risk
Provide adequate clearances.
• Around air openings
• To combustibles
• For service access.
Locate fireplace away from traffic areas.
WARNING
Note:
• Illustrations and photos reflect typical installations
and are FOR DESIGN PURPOSES ONLY.
• Illustrations/diagrams are not drawn to scale.
• Actual installation/appearance may vary due to
individual design preference.
• Hearth & Home Technologies reserves the right to
alter its products.
• Freestanding Installations (see Figure 3.2)
When installing this fireplace as a freestanding fireplace in
your yard, it must be enclosed to prevent impact damage
to the fireplace.
• Porch and Patio Installations
The fireplace will not perform as an exterior wall. Hearth
& Home Technologies recommends that 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 heaths should slope away from
the structure at 1/8 in. to 1/4 in. per foot. The fireplace can
be shimmed level.
• The cooling air hoods MUST be used if installing in
a combustible enclosure. Ducting is not necessary
between the hoods and the fireplace.
• If fireplace is installed on cement and totally enclosed with
non combustilbe materials (i.e. metal studs, cement board,
etc.) the cooling air hoods do not need to be installed.
• When Installed on Surfaces Where Water May Collect
or Cause Damage:
Hearth & Home Technologies recommends that a drainage
pan be placed under the unit. This can be constructed
of metal, adhesive polymer membrane (such as ice
and water shield) or other suitable materials. A means
of drainage out of the pan such as tubes or weep holes
should be provided. A slope of 1/8 in. to 1/4 in. per foot
towards the drain port is suggested. The fireplace can
be shimmed level. Hearths should slope away from the
front of the fireplace and chase at 1/8 in. to 1/4 in. per
foot. Spark strips must be used on top of any combustible
hearth materials used for moisture management.
