OUTSIDE AIR KIT AND GLASS DOOR
ACCESSORIES
A fireplace needs a steady supply of air in order to draw
properly. Many houses and apartments which are well
sealed lack sufficient air for normal operation. IN SUCH
HOUSES, IT IS RECOMMENDED THAT A COMBUSTION
AIR KIT BE INSTALLED. A combustion air kit will improve
the efficiency of any fireplace, especially if used in
conjunction with glass doors, because it allows you to use
outside air for combustion instead of heated room air.
Installing the fireplace on an outside wall will simplify the
installation of the combustion air kit and reduce the amount
of necessary duct work. Install the air kit according to the
separate installation instructions packed with it. If an air kit
is to be installed, IT MUST BE INSTALLED AT THE TIME
THE FIREPLACE IS INSTALLED, before its enclosure is
finished.
The fireplace includes an integral barometric damper. The
control lever is located on the left side behind the mesh
screen.
GAS LINE
If you plan to install a gas line, it must be installed at the
time of framing the fireplace. The gas line must be installed
in accordance with local codes. See p.12 for installation
instructions.
DRAFTS
The location for the fireplace should be away from objects
such as frequently opened doors and central heat air outlets
and inlets that will create drafts and possibly hamper the
normal flow of air into the fire.
LOCATING THE AREA WHERE THE FLUE
PIPE WILL PASS THROUGH THE CEILING
AND THE ROOF
It is very important that you determine where the flue
(chimney) will go through the ceiling and roof. Check the
structure of your home to see that the location you have
chosen will make installation as easy as possible. Using a
plumb bob, hold the string from the ceiling and drop it,
moving the string until the plumb bob is in the center of the
flue collar opening, (see figure 3). Mark the spot on the
ceiling. You may wish to drive a nail through the ceiling at
this spot. Then go into the attic and find the nail. Using the
plumb bob with the ceiling nail as the center point of the
flue, mark the center of the area on the roof through which
the flue will pass. This is to see if it is possible to cut your
opening for the flue in both the ceiling and roof without
cutting either roof rafters or ceiling joists. A location that
requires cutting the least number of joists and rafters will
simplify the installation and reduce the cost. The structural
integrity of a home's floor, walls, ceiling and roof must be
maintained. It is not recommended to cut roof trusses.
CHIMNEY OUTLET
Thought should be given to the proposed location of the
chimney outlet on the roof. Objects such as trees, adjacent
buildings or embankments that are too close to the chimney
can create air circulation problems during windy weather
that could affect the way the fireplace draws air.
After careful consideration, choose the location for your
fireplace to achieve the simplest installation for maximum
efficiency.
FIREBOX AND CHIMNEY SYSTEM
CLEARANCES
The fireplace may be placed directly on a combustible floor,
against a combustible wall at marked clearances or on a
raised wooden platform.
If the fireplace is to be installed on a raised platform, the
platform must be a continuous level surface.
The fireplace must be secured in place so it cannot shift
positions. The nailing flanges on the sides of the firebox
make securing the firebox to the frame quick and easy. The
nailing flanges were designed to allow the installation of
1/2" wallboard or plywood flush with the face of the
fireplace.
Only the header (see figure 4) may rest on the standoffs on
top of the firebox.
Combustible materials may not cover any part of the black
metal surrounding the firebox opening. See figure 4.
Do not install the firebox over vinyl floors or carpet.
Combustible floors in front and to the sides of the firebox
opening must be protected by a noncombustible hearth
extension as shown in figure 4.
THE CAUTIONS BELOW RELATE TO LOCATIONS ON
FIGURE 4, (letters on pictures correspond with items
below).
A.
When installing the hearth extension, a protective
metal satety strip is not required below the front
face of the fireplace and mating edge of the hearth
extension if the following steps are taken:
1)
The pre-fabricated hearth extension (or site built) must
be secured to the floor of the home to prevent shifting.
Various methods of attachment may be used including
screws, nails, or common construction adhesives.
2)
After the fireplace and hearth extension have been
secured, the gap between the fireplace and hearth
extension must be filled or sealed with a non-
combustible grout, caulk, or sealant.
(OR)
If a protective metal strip is used under the space between
the fireplace and hearth extension, sealing of the gap
between the fireplace and hearth extension is optional.
B. COMBUSTIBLE MATERIALS MUST NOT OVERLAP
THE SURFACE OF THE BLACK FRONT FACE
PANELS. COMBUSTIBLES MAY BE INSTALLED
OVER THE SIDE NAIL FLANGES UP TO THE EDGE
OF THE FRONT FACE SURFACE.
