IMPORTANT:
Vent-free gas log heaters add
moisture to the air. Although this is beneficial,
installing firebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See
Air for Combustion
and Ventilation
, page 5.
IMPORTANT:
Make sure the firebox is level. If
firebox is not level, log set will not work properly.
Note: Your Vanguard firebox is designed to
be used in zero clearance installations. Wall
or framing material can be placed directly
against any exterior surface on the rear, sides
or top of your firebox, except where standoff
spacers are integrally attached. If standoff
spacers are attached to your firebox, these
spacers can be placed directly against wall
or framing materials.
Use the dimensions shown for rough openings
to create the easiest installation (see
Built-In
Firebox Installation
, page 12).
INSTALLATION CLEARANCES
WARNING: Maintain the
minimum clearances. If you can,
provide greater clearances from
floor, ceiling and adjoining wall.
Carefully follow the instructions below. This
will ensure safe installation.
Minimum Clearances For Side Combus-
tible Material, Side Wall and Ceiling
A. Clearances from the side of the fireplace
cabinet to any combustible material and
wall should follow diagram in Figure 6.
Example:
The face of a mantel, bookshelf,
etc. is made of combustible material and
protrudes 3
1
/
2
" from the wall. This com
-
bustible material must be 4" from the side
of the fireplace opening (see Figure 6).

opening to the ceiling should not be less
than 42".

Top 42", Left and Right Sides 16",
Bottom and Rear 0", Front 36"
Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in fire
-
box, you must meet the minimum allowable
clearance between mantel shelf and top of
firebox opening shown in Figure 7. These are
the minimum allowable mantel clearances
for a safe installation. Use larger clearances
wherever possible to minimize the heating of
objects and materials placed on the mantel.
CAUTION: Close screens
before operation of vent-free
gas log heater. Do not allow the
heater to touch or extend beyond
the fireplace screen.
If your installation does not meet the minimum
clearances in Figure 7, you must:
• raise mantel to an acceptable height,
OR
• remove mantel.
