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.
