BACKDRAFTING
For installations in which the fan is connected to a range hood, or if an exhaust grille connected
to the fan is located above or near the cooking surface, as shown below, be sure to observe the
following safety warnings:

WARNING
TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.
(Use only galvanized steel ductwork.)
Use only galvanized steel ductwork in accordance with all
applicable codes.
(Note: If the fan is not connected to a range hood, or a grille in the
vicinity of the cooking surface, other approved ducting may be used as
described in "Ducting" section of basic instructions.)
TO REDUCE THE RISK OF A RANGE
TOP GREASE FIRE:
A
. Never leave surface units unat-
tended at high settings. Boilovers
cause smoking and greasy
spillovers that may ignite. Heat
oils slowly on low or medium
settings.
B
. Always turn hood ON when cook-
ing at high heat or flambeing
food (i.e. Crepe Suzette, Cher-
ries Jubilee, Peppercorn Beef
Flambe).
C
. Clean ventilating fans frequently.
Grease should not be allowed to
accumulate on fan or filter.
D
. Use proper pan size. Always use
cookware appropriate for the size
of the surface element.
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE
TOP GREASE FIRE, OBSERVE THE FOLLOWING
a
:
A
. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray,
then turn off the burner. BE CAREFUL TO PREVENT BURNS. If the
flames do not go out immediately EVACUATE AND CALL THE FIRE
DEPARTMENT.
B
. NEVER PICK UP A FLAMING PAN — You may be burned.
C
. DO NOT USE WATER, including wet dishcloths or towels — a violent
steam explosion will result.
D
. Use an extinguisher ONLY if:
1. You know you have a Class ABC extinguisher, and you already know
how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit.
the case of continuous exhaust, even
though often at lower flow rates, the
potential for backdrafting the flue of
these appliances does exist, and repre-
sents a dangerous situation. The Na-
tional Fuel Gas Code, available from
the American Gas Association, Appen-
dix H, provides a Recommended Pro-
cedure for Safety Inspection of an Ex-
isting Appliance Installation. This pro-
cedure should be followed to determine
the presence of adequate combustion
air, while all exhaust fans are operating
at maximum speed, and all doors and
windows are closed.
In the event that backdrafting occurs,
steps must be taken to provide suffi-
cient combustion air to the furnace or
boiler, following the guidelines of the
National Fuel Gas Code and all state
and local codes.
In especially tight homes heated with
naturally vented appliances, such as
gas, oil or wood-fired furnaces, boilers,
stoves or fireplaces, the exhaust sys-
tem may produce sufficient negative
pressure indoors to induce the
backdrafting of flue gases. This is quite
a common, though intermittent
occurence, with conventional exhaust
systems, such as vented kitchen range
hoods, clothes dryers, bath fans, etc. In
