Installation; Ventilation Air From Outdoors - Superior VD1824NR Operation Instructions Manual

AIR FOR COMBUSTION AND VENTILATION

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 floor. 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.
NOTICE: This heater is intended
for use as supplemental heat.
Use this heater along with your
primary heating system. Do not
install this heater as your pri-
mary heat source. If you have a
central heating system, you may
run system's circulating blower
while using heater. This will help
circulate the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
WARNING: A qualified ser-
vice person must install heater.
Follow all local codes.
CAUTION: This heater cre-
ates warm air currents. These
currents move heat to wall sur-
faces next to heater. Installing
heater next to vinyl or cloth wall
coverings or operating heater
where impurities (such as, but
not limited to, tobacco smoke,
aromatic candles, cleaning flu-
ids, oil or kerosene lamps, etc.) in
the air exist, may discolor walls
or cause odors.

NOTICE: State or local codes may
only allow operation of this appliance
in a vented configuration. Check your
state or local codes.
WARNING: If optional remote
control is used, make sure the se-
lector switch is in the OFF position
before installing heater.
WARNING: Before installing in
a solid fuel burning fireplace, the
chimney flue and firebox must be
cleaned of soot, creosote, ashes and
loose paint by a qualified chimney
cleaner. Creosote will ignite if highly
heated. A dirty chimney flue and fire-
box may create and distribute soot
within the house. Inspect chimney
flue for damage. If damaged, repair
flue before operating heater.
WARNING: Any outside air ducts
and/or ash dumps in the fireplace
shall be permanently closed at time
of appliance installation.
WARNING: Seal any fresh air
vents or ash clean-out doors located
on floor or wall of fireplace. If not,
drafting may cause pilot outage
or sooting. Use a heat-resistant
sealant. Do not seal chimney flue
damper.
