and ventilation. The air openings, o n the fu rnace, the air openings
to the area in which the furnace is installed, and the spacing around
the furnace must not be blocked or obstructed.
The combustion area and vent system should be inspected visually

rust, and scale can result in loss of efficiency and improper
performance if allowed to build up.This inspection should be done
by a trained service person.
