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: Position the fireplace as shown in figure 4a by sliding
the unit backward until the nailing straps on each side touches
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: Secure fireplace to floor using tie-down straps (see
figure 4) to prevent shifting.
HEARTH EXTENSION: (HE 36)
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. Use DESA hearth extension (see
accessories on page 11) HE 36 or an equal 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 extension from shifting and seal
the gap between the fireplace frame and hearth extension with
a non-combustible material (see figure 3).
WARNING: HEARTH EXTENSION IS TO BE
INSTALLED ONLY AS ILLUSTRATED.
OUTSIDE AIR KIT (MODEL AK6E)
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 is accessed through the
mobile home floor (Refer to AK-6 Installation Instructions for
details). In some instances, a wall installation is required (see
figure 5). Note: An AK6WE Air Kit must be ordered when a
sidewall installation is required (see accessories on page 11).
