INSTALLATION
CLEARANCES
WARNING: Maintain the mini-
mum clearances. If you can, pro-
vide greater clearances from
floor, ceiling, and adjoining wall.
Carefully follow the instructions below. This
will ensure safe installation.
Minimum Wall and Ceiling
Clearances (see Figure 6)
A. Clearances from the side of the firebox
opening to any combustible wall should
not be less than 16 inches for a cabinet
mantel or 12 inches for a corner instal-
lation.
B. Clearances from the top of the firebox
opening to the ceiling should not be less
than 42 inches.
C. When the firebox is installed directly
on carpeting or other combustible ma-
terial, other than wood flooring, the
firebox should be installed on a metal
or wood panel extending the full width
and depth of the enclosure.
INSTALLATION
CAUTION: Log heaters in-
stalled in this firebox create warm
air currents. These currents move
heat to wall surfaces next to fire-
box. Installing firebox next to vi-
nyl or cloth wall coverings or
operating firebox where impuri-
ties (such as tobacco smoke, aro-
matic candles, cleaning fluids,
oil or kerosene lamps, etc.) in the
air exist, may discolor walls.
IMPORTANT:
Vent-free gas log heaters
add moisture to the air. Although this is
beneficial, installing firebox in rooms with-
out enough ventilation air may cause mil-
dew to form from too much moisture. See
Air for Combustion and Ventilation, pages 4
through 6.
IMPORTANT:
Make sure the firebox is
level. If firebox is not level, log set will not
work properly.
NOTICE: A qualified service per-
son must install firebox. Follow
all local codes.
WARNING: Never install the
firebox
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,
clothing, or other flammable
objects are less than 42 inches
from the front, top, or sides of
the firebox
• in high traffic areas
• in windy or drafty areas

Ceiling
Mantel Clearances for
Conventional Installation
Note:
Clearances are
the same if using
optional cabinet mantel
or built-in installation.
MINIMUM
CLEARANCE
Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in
firebox, you must meet the minimum allow-
able clearance between mantel shelf and top
of firebox opening shown in Figure 7 on
page 8. These are the minimum allowable
mantel clearances for a safe installation.
Use larger clearances wherever possible to
minimize the heating of objects and materi-
als placed on the mantel.

NOTICE: This heater is intended
for use as supplemental heat. Use
this heater along with your pri-
mary heating system. Do not in-
stall this heater as your primary
heat source. If you have a central
heating system, you may run
system’s circulating blower while
using heater. This will help circu-
late the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
CAUTION: Do not allow the
vent-free gas log heater to touch
or extend beyond the fireplace
screen.
If your installation does not meet the mini-
mum clearances in Figure 7, page 8, you
must:
• raise the mantel to an acceptable height,
OR
• remove the mantel.
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 fire-
box, these spacers can be placed directly
against wall or framing materials.
Use the dimensions shown for rough open-
ings to create the easiest installation (see Built-
In Firebox Installation, pages 11 and 12).
