fireplace, you must take into consideration the following
guidelines:
1. The location must allow for proper clearances (see figures
1 & 2).
2. Consider a location where the fireplace would not be
affected by drafts, air conditioning ducts, windows or
doors.
3. A location that avoids the cutting of joists or roof rafters
will make installation easier.
4. An outside air kit is available with this fireplace. For
more details refer to section on outside air kit installation
on page 3.
MINIMUM CLEARANCES TO COMBUSTIBLES:
• Back and sides of fireplace …………………..3/4” Min.
Note: the ¾ “ clearance is not required at the nailing flanges
• Ceiling to Top of Opening ……………….. 67-7/8” Min.
• Floor* ………………………….…………………0” Min.
*See step 2 of “Installing the Fireplace” below
• Wall to front of Fireplace ……………………….36” Min.
• Perpendicular Wall to Opening of Unit ………...14” Min.
• Top Spacers …………………..…………………..0” Min.
• Mantel Clearances ……………………………see page 7
“Finishing your Fireplace”
• Chimney Outer Pipe Surfaces ……………………1” Min.
WARNING: DO NOT PACK REQUIRED AIR SPACES WITH
INSULATION OR OTHER MATERIALS.
MINIMUM/MAXIMUM CHIMNEY HEIGHT:
The MINIMUM height of the chimney, measured from the
base of the fireplace to the flue gas outlet of the termination, is
11.5 feet for straight flue or a flue with one elbow set. The
maximum distance between elbows is 2 feet. For systems with
2 elbow sets, the MINIMUM height is 22 feet. The maximum
height of any system is 50 feet. This measurement includes the
fireplace, chimney sections and the height of the termination
assembly at the level of the flue gas outlet (see pg. 6, fig. 16).
FRAMING AND INSTALLING THE FIREPLACE
STEP 1: Frame the opening for the fireplace using the
dimensions shown in figure 1 or 2.
STEP 2: If the fireplace is to be installed directly on carpeting,
tile (other than ceramic), or any combustible material other
than wood flooring; the fireplace must be installed upon a
metal or wood panel extending the full width and depth of the
fireplace.
STEP 3: Set the fireplace directly in front of this opening and
slide the unit back until the nailing flanges touch the side
framing.
STEP 4: Check the level of the fireplace and shim with sheet
metal if necessary.

STEP 5: Before securing fireplace to prepared framing, the
ember protector (provided), must be placed between the hearth
extension (not supplied), and under the bottom front edge of
the fireplace to protect against glowing embers falling
through. If the fireplace is to be installed on a raised platform,
a Z-type ember protector (not supplied) must be fabricated to
fit your required platform height. The ember protector should
extend under the fireplace a minimum of 1-½”. The ember
protector should be made of galvanized sheet metal (28ga.
minimum) to prevent corrosion.
STEP 6: Using screws or nails, secure the fireplace to the
framing through flanges located on the sides of the fireplace
(see figure 4).

Figure 3 HEARTH EXTENSIONS
WARNING: HEARTH EXTENSION IS TO BE
INSTALLED ONLY AS ILLUSTRATED.
Figure 2 CORNER INSTALLATIONS
HEARTH EXTENSION:
A hearth extension projecting a minimum of 16” in front of
and a minimum of 8” beyond each side of the fireplace
opening is required to protect combustible floor construction
in front of the fireplace. Fabricate a hearth extension using a
material which meets the following specifications: a layer of
non-combustible, inorganic material having a thermal
conductivity of K=0.84 BTU IN/FT. HR. F (or less) at 1”
thick. [For example, if the material selected has a K factor of
0.25, such as glass fiber, the following formula would apply.
0.25/0.84 x 1.0” = 0.30 thickness required. Thermal
conductivity “K” of materials can be obtained from the
manufacturer or supplier of the non-combustible material.] If
the hearth extension is to be covered, use non-combustible
material such as tile, slate, brick, concrete, metal, glass,
marble, stone etc. Provide a means to prevent the hearth
Figure 4
OPTIONAL OUTSIDE AIR KIT (MODEL AK4 / AK4F)
The installation of an outside air kit should be installed during
the rough framing of the fireplace due to the nature of its
location. Outside combustion air can be accessed through a
vented crawl space (AK4F) or through a sidewall (AK4). See
accessories on page 10 for details.
