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 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 thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.

IMPORTANT: Vent-free gas log heaters add
moisture to the air. Although this is benecial,
installing rebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See, page 8.
IMPORTANT: Make sure the rebox is level.
If rebox is not level, log set will not work
properly.
Note: Your 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 rebox, except where standoff spacers
are integrally attached. If standoff spacers are
attached to your 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).
