Direct-Fired means that all of the combustion products enter
the heated space. Even though this heater operates very close
to 100 percent combustion efficiency, it still produces small
amounts of carbon monoxide. Carbon monoxide (called CO)
is toxic.
CO can build up in a heated space and failure to provide
adequate ventilation could result in death. The symptoms of
inadequate ventilation are:
headache
dizziness
burning eyes and nose
nausea
dry mouth or sore throat
So, be sure to follow advice about ventilation in these operating
instructions.
