Locate the two protective metal hearth strips measuring
approximately 26 in. x 4 in. (660 mm x 102 mm) included
with this fireplace.
•
Slide each metal strip 2 in. (51 mm) under front edge of
fireplace.
•
Overlap strips in the middle of fireplace opening by 1 in.
(25 mm) minimum.
•
Metal strips must extend beyond the front and sides
of the fireplace opening by at least 2 in. (51 mm),
Figure 3.6).

G. Outside Air Kit
When you install the outside air kit, Hearth & Home Tech-
nologies recommends you utilize the shortest duct run to
optimize the performance of the outside air kit. The outside
air inlet hood should be positioned in a manner that will not
allow snow, leaves, etc. to block the inlet. In some instal-
lations the air duct may need to be run vertically. In such
an installation, a 3 ft (914 mm) height difference must be
maintained from the top of the uppermost chimney section
to the outside air inlet hood.
Refer to Figures 3.8 and 3.9 when placing the outside air
inlet hood.
CAUTION! Risk of Fire or Asphyxiation! DO NOT draw
outside combustion air from wall, floor or ceiling cavity, or
enclosed spaces such as an attic or garage.
•
DO NOT place outside air inlet hood close to exhaust
vents or chimneys. Fumes or odor could be drawn into
the room through the fireplace.
•
Locate outside air inlet hood to prevent blockage from
leaves, snow/ice, or other debris. Blockages could cause
combustion air starvation.
