GENERAL INFORMATION
The PureFire Catalytic Hood can be installed in a wood burning
masonry fireplace or a factory built zero clearance fireplace. The
PureFire Catalytic Hood can easily be installed in less than an
hour. Four mounting screws will hold the two mounting brack-
ets in place. Included with the hood are two sets of mounting
brackets (for masonry fireplace or factory-built fireplace). The
PureFire Catalytic Hood has a trapezoidal shape to fit the angu-
lar sides of the firebox. The hood is equipped with adjustable
extensions that slide in and out. The PureFire Catalytic Hood
should be installed after the fireplace is completely finished. It
is designed to be installed as an add-on device. It is mounted on
two brackets that are mechanically attached to the side walls of
the firebox. Ensure that the firebox is structurally sound before
beginning the installation.

The height of the bracket installation is determined by the fire-
place opening. The brackets should be installed so they are
even or above the height of the fireplace opening (lintel) or the
smoke shelf. The brackets can be used to identify the location
of the mounting screw holes. A black felt tip should be used
to identify the location for drilling. Two holes will need to be
drilled on each side of the firebox. For masonry application, the
brackets are attached using masonry screws (provided). For
factory-built fireplace application, brackets are attached using
self-drilling sheet metal screws (provided). Make sure that the
brackets are installed as shown. The bracket end tab should be
facing the front of the firebox. The end tab will prevent the hood
from moving. After the brackets are installed, the hood should
be adjusted to the correct dimension to properly fit into the
brackets. Measure the distance between the installed brackets
on both front and back. Move the adjustable extensions on the
hood until the front and back on the hood extensions equal the
dimensions of the mounting brackets. Tighten the retention
screws on each side of the hood.
The PureFire Catalytic Hood can now be installed in the fire-
box. Position the hood in the brackets so that it is securely in
place. The PureFire Catalytic Hood should be located against
the back wall of the firebox directly above the grate (see Figure
3). Minimum Distance between the leading edge of the smoke
shelf and the hood is 6" (see Figure 4). The damper Handle
(if required) should pass between the combustor blocks and
remain operational. Chain operated units will have the chain
in front of the hood.
The HearthCAT™ emission control system is now
ready for use.
