IMPORTANT:
Vent-free gas log heaters add
moisture to the air. Although this is benefi cial,
installing fi rebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See
Air for Combustion
and Ventilation
, page 7.
IMPORTANT:
Make sure firebox is level.
If fi rebox is not level, log set will not work
properly.
Note: Your fi rebox is designed to be used in
zero clearance installations. Wall or framing
material can be placed against any exterior
surface on rear, sides, top or bottom of fi rebox,
except where standoff spacers are integrally
attached. If standoff spacers are attached to
fi rebox, these spacers can be placed directly
against wall or framing materials.
Use dimensions shown for rough openings
to create the easiest installation (see
Built-In
Firebox Installation
, page 11).
INSTALLATION CLEARANCES
WARNING: Maintain the
minimum clearances. If you can,
provide greater clearances from
fl oor, ceiling and adjoining wall.
Carefully follow these instructions. This will
ensure safe installation.
Minimum Wall and Ceiling Clearances (see
Figure 5)
A. Clearances from side of fi replace cabinet
to any combustible material and wall
should follow diagram in Figure 5.
Example:
The face of a mantel, bookshelf,
etc. is made of combustible material and
protrudes 3
1
/
2
" from wall. This combus-
tible material must be 4" from side of
fi replace cabinet (see Figure 5).
B. Clearances from top of fi rebox opening to
ceiling should not be less than 42".
C. When fi rebox is installed on carpeting or
other combustible material, other than
wood fl ooring, fi rebox should be installed
on a metal or wood panel extending full
width and depth of enclosure.
D. Clearances from bottom of fi rebox to fl oor
is 0".
INSTALLATION

Figure 5 - Minimum Clearance for
Combustible to Wall
*Minimum 16" from Side Wall
*
These fi reboxes can be installed as free-
standing units against a wall with approved,
optional cabinet mantels or as a built-in unit.
Clearances are the same for either installa-
tion method.
CAUTION: Do not install fi re-
box directly on carpet or vinyl.
Example
Mantel Clearances for Built-In Installation
If placing custom mantel above built-in fi rebox,
you must meet minimum allowable clearance
between mantel shelf and top of fi rebox open-
ing shown in Figure 6, page 11. These are
minimum allowable mantel clearances for a
safe installation. Use larger clearances wher-
ever possible to minimize heating of objects
and materials placed on mantel.
CAUTION: Do not allow
vent-free gas log heater to
touch or extend beyond fi re-
place screen.
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above fi re-
box may become hot to the
touch. If installed properly,
these temperatures meet the
requirement of the national
product standard. Follow all
minimum clearances shown in
this manual.
