maybefoundon theunitintheULRATINGPLATElocatedat the
interior of the firebox's opening (see Figure 1, page 2).
BEFOREYOUBEGIN
Beforebeginningthe installationofyourfirebox, readtheseinstruc-
tions through completely.
This firebox and its approved components are safe when installed
and operated according to this installation and operation manual.
Unless you use Vanguard approved components tested for this
firebox, YOU MAY CAUSE A FIRE HAZARD!
The DESA International warranty will be voided by, and DESA
International disclaims any responsibility for the following actions:
A) Modification of the firebox or any of the components manufac-
tured by DESA INTERNATIONAL unless otherwise permitted
by DESA INTERNATIONAL.
B) The use of a firebox insert or any other component part not ap-
proved by DESA INTERNATIONAL in combination with a
DESA INTERNATIONAL firebox.
C) Installation and/or operation in a manner other than instructed in
this manual.
D) The burning of any other fuel not tested or approved by DESA
INTERNATIONAL in this wood-burning firebox.
PROPER INSTALLATION is the most important step in ensur-
ing a safe and continuous operation of this firebox.
Although grounding may not be required by code in your area, it
must be electrically grounded in accordance with local codes or, in
theabsenceoflocalcodes,withtheNationalElectricalCode,ANS/
NFPA 70-1987.
This firebox is intended for installation in accordance with the
National Fire Protection Association Standard for Chimneys, Fire-
places, Vents, and Solid-Fuel Burning Fireplaces, NFPA 211, and in
accordance with codes such as the BOCA Basic/National Code, the
Standard Mechanical Code, and the Uniform Building Code.
NOTE: Installation and repair should be done by a qualified
installer. The firebox and chimney system should be inspected
and cleaned before use and periodically thereafter especially
during heating season to ensure a safe operating system.
This firebox is not intended to be used as a substitute for a
furnace to heat an entire home. Use for supplementary
heating only.
SELECTINGLOCATION
To determine the safest and most efficient location for your firebox,
you must take into consideration the following guidelines:
1. The location must allow for all the proper clearances (see sec-
tion on clearances, page 4).
2. Consider a location where the heat output 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. If an outside air kit is to be installed, accessibility to outside
combustion air must be considered. This can also be achieved
through a vented crawl space in some cases, for more details
refer to section on outside air kit installation.
The typical installation for a peninsula is a projected installation,
which allows you to extend the firebox any distance into the room. A
projectionmaybeidealforanewadditiononanexisting,finishedwall.

ALSO IN SELECTING A LOCATION, THE
FOLLOWING PRECAUTIONS MUST BE
OBSERVED;
1. Do not connect this firebox to a chimney system other than a
Vanguard chimney system.
2. Installinanareaproviding ventilation and adequate combustionair.
3. Due to high temperatures do not locate this firebox in high traf-
fic areas or near furniture and draperies.
4. Provide adequate clearances around air openings into the com-
bustion chamber. NEVERobstruct the front opening of the fire-
box or the flow of combustion and ventilation air.
5. Do not locate in or near an area where gasoline or other flam-
mable liquids may be stored. The firebox area must be kept clear
and free from these combustible materials.

FRAMING
Construct framing using dimensions shown in Figures 5, 7, and 8,
page 5, depending on your particular installation.
If the firebox is to be installed directly on carpeting, tile (other than
ceramic),orany combustible material other than wood flooring; the
firebox must be installed upon a metal or wood panel extending the
full width and depth of the firebox.
Before securing firebox to prepared framing, metal safety strips
(provided) must be placed between hearth extensions (not sup-
plied) and bottom front edge of firebox to protect against glowing
embers (Figure 6, page 5).
Ifthefireboxistobeinstalledonaraisedplatform,a"Z-type"metal
safety shield (not supplied) must be fabricated to fit your required

FIREBOXSPACER
Firebox spacers are required at each point where the chimney
penetrates a floor or ceiling, joist space. Their purpose is two fold;
theyestablish andmaintaintherequiredclearancebetweentheouter
pipe and combustible materials, and they also serve as a shield
between floors as required by most codes.
When the pipe passes through a framed opening into a living space
above, a firestop must be placed on the ceiling below (Figure 16).
