NOTICE:
• 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.
NOTICE: In addition to these framing dimensions, also
reference the following section:
• Framing and Clearances (Section 3).
NOTICE:
A minimum 1-1/2 in. air clearance at the back and
a minimum 1-1/2 in. air clearance to the sides of
the fireplace assembly must be maintained.
Chimney sections at any level require a 2 in. mini-
mum air space clearance between the framing
and chimney sections.
B. Design and Installation Considerations
NOTICE: Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, fire
offi cials or authorities having jurisdiction over restrictions,
installation inspection and permits.
1. Selecting Fireplace Locations
This fi replace may be used as a room divider, installed
along a wall, across a corner or used in an exterior chase.
See Figure 2.2.
Locating the fi replace in a basement, near frequently
opened doors, central heat outlets or returns, or other
locations of considerable air movement can affect the
performance.
Outside air must be used for combustion. This fi replace-
comes equipped with an outside air inlet to feed combus-
tion air from outside the home, along with an outside air
termination cap; the rigid metal duct is required but not
supplied. Consideration should be given to these factors
before deciding on a location.

7Heatilator • Birmingham BIR50-B Installation Manual • 4059-701 • Rev B • 2/6/13
2. Locating Fireplace & Chimney
Location of the fi replace and chimney will affect perfor-
mance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fi re.
• Penetrate the highest part of the roof. This minimizes
the effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the fi replace location relative to fl oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Section 4.

• Install the outside air kit with the intake facing prevailing
winds during the heating season.
• Ensure adequate outdoor air for all combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fi replace.
• Avoid installing the fi replace near doors, walkways or
small isolated spaces.
• Recessed lighting should be a “sealed can” design.
• Attic hatches weather stripped or sealed.
• Attic mounted duct work and air handler joints and seams
taped or sealed.
