INTRODUCTION:

This fireplace model is a wood burning fireplace intended and
approved for installation in either residential homes or
buildings of standard construction. This fireplace system
requires the utilization of DESA 8 inch, double-wall, and
snap-lock flue pipe system. Optional glass doors in several
finishes are available for this fireplace (See Replacement and
Accessories parts on page 11).

BEFORE YOU BEGIN:

Before beginning the installation of your fireplace, read these
instructions:

• All DESA components and fireplaces are safe when
installed according to this manual. Use of any
components that have not been designed and tested for
this fireplace system may cause a fire hazard.

• The DESA warranty will be voided by and DESA
disclaims any responsibility for the following actions:
a) Modification of the fireplace, components, doors,

chimney system, fans, air inlet system, damper
control, etc.

b) Use of any component part not manufactured or

approved by DESA in combination with a DESA

fireplace system.
PROPER INSTALLATION is the most important step in
ensuring safe and continuous operation of this fireplace.

SELECTING LOCATION:

To determine the safest and most efficient location for your
fireplace, consider the following guidelines:

• The location must allow for all proper clearances (see

page 3).

• The location should be in a place where the fireplace will

not be affected by drafts such as air condition ducts,
windows or doors.

• A location that avoids the cutting of joists or roof rafters

makes installation easier.

• If an outside air kit is to be installed, accessibility to

outside combustion air must be considered. In some
cases, this can be achieved through a vented crawl space.
For more details, see section on outside air kit installation
on page 4.

• If a Fan Kit is to be installed, an electrical supply must be

accessible.

• If a gas line is to be installed, consider the location of gas

supply.
