UNIT OPERATION HAZARD
Failure to follow this caution may result in personal
injury.
Failure to follow this warning could result in personal
injury or death.
For proper and safe operation the furnace needs air for
combustion and ventilation. Do not block or obstruct air
openings on the furnace, air opening to the area in
which the furnace is installed, and the space around the
furnace.
Inspect the combustion area and vent system before each
heating season. An accumulation of dirt, soot, or rust can
mean a loss of efficiency and improper performance. Buildups
on the main burners can cause faulty firing. This "delayed
ignition" is characterized by an alarmingly loud sound.
NOTE: If your furnace makes a loud noise when the main
burners are ignited, shut down the furnace and call your
