3. Selecting Fireplace Location Outdoors
The LM42-SS (Stainless) fireplace may be installed out
-
doors.This 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. Mois
-
ture penetration must be considered for construction that
places the fireplace against structure walls or on moisture
sensitive surfaces.
• Exterior Walls (see Figure 2.4)
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.
• Freestanding Installations (see Figure 2.5)
When installing this fireplace as a freestanding fireplace
on your porch, patio or in your yard, it must be enclosed
to prevent impact damage to the fireplace. The exterior
of the enclosure may be finished in a textured plywood,
a wood clapboard siding, brick, or a cultured stone. Vinyl
siding is not recommended for use on the front of the
fireplace due to the heat the fireplace produces. This
can cause the vinyl siding to deteriorate.
• Cooling Air
WARNING!
Cooling air must be provided when install-
ing in freestanding combustible enclosure or on combus-
tible surface.
•
Locate cooling air inlet to prevent blockage from leaves,
snow/ice, or other debris. Blockages could cause the
unit to overheat.
•
Cooling air can be provided by cutting a 6 in. hole in
the enclosure and attachng an outside air inlet hood,
Part# 4059-051 or covering it with screen. *No ducitng
is required.
Fire Risk
Provide adequate clearances.
• Around air openings
• To combustibles
• For service access.
Locate fireplace away from traffic areas.

• Outside Air Kit
The Outside Air Kit is required for the performance of
the fireplace even though it is installed outdoors. The
Outside Air Kit is installed on the right hand side of the
fireplace.
• Cut a 6-1/2 in. (165mm) hole in outside wall to
accomodate air piping.
•
Use 6 in. (152mm) flex (not supplied) to directly
connect outside air to fireplace intake.
• Use the supplied outside air inlet hood.
It can be
painted to match/accent the color of the structure.
• 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.
