The furnace should be inspected periodically (monthly during the heat-
ing season) for presence of soot on the vent. Soot is formed whenever
combustion is incomplete. This is a visual warning that the furnace is op-
erating in an unsafe manner. If soot is observed on the vent, immediately
shut the furnace OFF and contact a qualified service agency. Operating
the furnace under this condition could lead to serious property damage,
personal injury or loss of life.
To ensure your personal safety, do not obstruct or alter the furnace in any
manner. Do not install screens over the vent for any reason. Screens will
become restricted and cause unsafe furnace operation. For your safety,
only the manufacturer's factory authorized parts should be used on your
furnace.
NOTE: For RV models with touch screens, the furnace controls may be
included on the selectable menu screens of the touch screen.
