9.     Turn   off  heater   before  using
        furniture   polish,  wax,   carpet
        cleaner, or  similar products.  If

Carbon      Monoxide      Poisoning:

Early    signs    of    carbon    monoxide
poisoning    resemble    the    flu    with
headaches,  dizziness,  or    nausea.
If   you  have  these  signs, the  heater

fected  by  carbon  monoxide  than
others.  These    include    pregnant
women, persons  with  heart  or  lung
disease  or  anemia, those  under   the
influence  of    alcohol,    and    those
at  high  altitudes.

Propane/LP  Gas:

   Propane/LP  gas

is odorless. An  odor-making  agent
is added  to  Propane/LP  gas.  The
odor helps  you  detect  a  Propane/LP
gas  leak.  However,  the odor added to
Propane/LP gas can  fade. Propane/
LP  gas  may be  present  even though
no  odor  exists.

stand  all  warnings. Keep  this  manual
for  reference.  It  is  your  guide  to  safe
