• Aldehydes have a strong pungent, acrid smell
that can cause nausea.
• Carbon monoxide is tasteless, colorless and
odorless. It can cause headaches, flu-like
symptoms or nausea. We refer to all these
symptoms as nausea in this manual. It can also
cause death by asphyxiation.
2.2 STORAGE AND USE OF FLAMMABLE,
CORROSIVE AND COMBUSTIBLE
PRODUCTS NEAR YOUR FURNACE
WARNING
A loud noise may mean faulty burner
ignition. If your furnace makes a loud
noise, turn it off. Follow instructions in
Section 4.B.2. If you don’t turn off your
furnace, it could cause fire or an explosion
resulting in damage, injury or death.
WARNING
Do not operate furnace with blower door
open or removed. Do not alter furnace to
allow operation with blower door removed.
Doing either should allow combustion
products to circulate throughout the
furnace area causing nausea, asphyxiation
or fire resulting in damage, injury or death.
WARNING
Front door must be in place during furnace
operation. Hot surfaces behind front door.
WARNING
Never store or use flammable liquids or
vapors near or on your furnace. These
include gasoline, kerosene, cigarette
lighter fluid, cleaning fluids, solvents, paint
thinners or painting compounds.
Flammable vapors can travel great
distances before igniting.
WARNING
Never store or use anything near or on
your furnace that can produce vapors that
are corrosive to gas-fired furnaces.
Vapors from products containing chlorines,
fluorines, bromines and iodines can cause
vent system or heat exchanger failure.
Examples of such products are spray or
aerosol containers, detergents, bleaches,
cat litter, waxes, adhesives, solvents and
other cleaning compounds. Vent system
or heat exchanger failure could cause
nausea, asphyxiation or fire resulting in
damage, injury or death.
WARNING
Any unfamiliar smell can alert you to
presence of gas or aldehydes. If you
detect any unfamiliar odor follow
instruction in Section 4.B.1. Otherwise,
nausea, asphyxiation or fire could occur
resulting in damage, injury or death.
WARNING
Do not block or cover combustion
openings in the furnace. Blocking or
covering these openings could cause
nausea, asphyxiation or fire resulting in
damage, injury or death.
WARNING
Never store anything combustible near or
on your unit. A fire could occur resulting in
damage, injury or death.
