AIR FOR COMBUSTION AND VENTILATION
Figure 5 - Ventilation Air from Outdoors
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: A qualifi ed service
person must install fi rebox. Follow
all local codes.
WARNING: Maintain the minimum
clearances. If you can, provide greater
clearances from fl oor, ceiling and
adjoining wall.
WARNING: Never install the
fi rebox
• in a bedroom or bathroom*
• in a recreational vehicle
• where curtains, furniture, clothing
or other fl ammable objects are less
than 42" from the front, top or sides
of the fi rebox
• in high traffi c areas
• in windy or drafty areas
* Unless the installed log set is
rated at 10,000 Btu/Hr or less in a
bedroom or 6,000 Btu/Hr or less in
a bathroom.
CAUTION: Log heaters installed
in this fi rebox create warm air cur-
rents. These currents move heat to
wall surfaces next to fi rebox. Install-
ing fi rebox next to vinyl or cloth wall
coverings or operating fi rebox where
impurities (such as, but not limited
to, tobacco 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
Air for Combustion
and Ventilation
,
Page 8.
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 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 Built-In
Firebox Installation, Page 12).
