PROPER INSTALLATION is the most important step in ensuring
safe and continuous operation of this firebox. Consult the local
building codes as to the particular requirements concerned with the
installation of all factory built fireboxes. Although grounding may
not be required by code the manufacturer recommends it.
This firebox is not intended to be used as a substitute for a furnace
to heat an entire home. Use for supplementary heating only.
MINIMUM CLEARANCES TO COMBUSTIBLES
Framing materials may safely make direct contact with the spacers
on the top of the firebox. The firebox may sit directly on combus-
tible flooring. The firebox opening must not be less than 30 inches
from a combustible, perpendicular sidewall. A 2-inch minimum air
space clearance between combustible materials and the chimney
must be absolutely maintained. A 19-inch inside chase dimension
is required as a minimum size. A 1-inch airspace is required around
back and sides of firebox.
WARNING: DO NOT PACK REQUIRED AIR SPACES
WITH INSULATION OR OTHER MATERIALS.
HEIGHT
The minimum height of the chimney, measured from the base of the
firebox to the flue gas outlet, is 16 feet for straight flues or a flue with
one elbow set. For systems with 2 elbow sets, the minimum height
is 16 feet. The maximum height of any system is 60 feet. This
measurement includes the firebox, chimney sections and the effec-
tive height of the termination assembly.
INSTALLING THE FIREBOX
STEP 1: Frame the opening for the firebox using the dimensions
shown in Figure 2 or Figure 3.
STEP 2: Sit the firebox directly in front of this opening and slide the
unit back until the mounting flanges touch the side framing.

galvanized steel ember protector (provided) must be installed be-
tween the firebox and the hearth extension as illustrated in Figure 16,
page 7.
STEP 5: Secure the firebox to the framing through the flanges
located on the sides on the firebox with 8-penny nails.
