Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the fl oor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the
National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation
for required size
of ventilation grills or ducts.
IMPORTANT:
Do not provide openings
for inlet or outlet air into attic if attic has a
thermostat-controlled power vent. Heated air
entering the attic will activate the power vent.

WARNING: Never install
fi rebox
• in a bedroom or bathroom*
• in a recreational vehicle
• where curtains, furniture,
clothing, or other fl ammable
objects are less than 36"
from front or 42" from top of
fi rebox; for side clearances
see Figure 4, Page 11
• in high traffi c areas
• in windy or drafty areas
* Unless installed log set is
rated at 10,000 Btu/Hr or less.
WARNING: A qualifi ed ser-
vice person must install fi rebox.
Follow all local codes.
CAUTION: Log heaters in-
stalled in this firebox create
warm air currents. These currents
move heat to wall surfaces next
to fi rebox. Installing fi rebox next
to vinyl or cloth wall coverings or
operating fi rebox where impuri-
ties (such as, but not limited to, to-
bacco smoke, aromatic candles,
cleaning fl uids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls or cause odors.
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,
Page 8
.
IMPORTANT:
Make sure the fi rebox 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 the rear, sides, top or bottom of
your fi rebox, except where standoff spacers
are integrally attached. If standoff spacers are
attached to your fi rebox, these spacers can
be placed directly against wall or framing ma-
terials. Use the dimensions shown for rough
opening to create the easiest installation.
Use dimensions shown for rough openings
to create the easiest installation (see

).
NOTICE: The fi rebox identifi ca-
tion label (including model num-
ber, serial number, clearances,
etc.) is located on a chain under
the bottom refractory.
