SECTION III: OWNERS INFORMATION
AND SEASONAL INFORMATION
How the Furnace Works
This furnace may be installed in the downflow position.
Figure 1 shows a typical model in the downflow position. The
furnace is equipped with a motor time delay, transformer,
circuit breakers, and a blower assembly. The transformer
provides 24 VAC to the thermostat. When the thermostat calls
for heat the relay(s) energize sending 240 VAC thru the limit
switches to the electric heaters causing them to get hot. The
indoor fan motor is then energized on the low speed tap and
the circulating blower draws cool air from the living space(s),
passes it across the heater coils and circulates the warmed air
through the duct work to the living space(s). When the
thermostat is satisfied the electric heaters are de-energized.
The blower is also de-energized and the heating cycle has
ended and the furnace is ready for the next call for heat to start
the next cycle.
The furnace is equipped with the controls necessary for proper
and safe operation. Circuit breakers and fuse location are
shown in Figure 1.
Examination of the furnace
The home owner should perform a visual examine the furnace
every month for any defects or problems. The items to be
inspected are:
1.
The physical support of the furnace is sound without
sagging cracks, gaps, etc. around the base so as to provide
a seal between the support and the base.
2.
The furnace casing for any obvious signs of deterioration
from rust or corrosion.
3.
The return and supply duct connections are physically
sound and are sealed to the furnace casing.
4.
The furnace must be serviced by qualified personnel
annually, preferably at the start of each heating season.

The Service Technician
The furnace’s best friend is a qualified service technician. If
the unit gives any indication of improper operation, call the
service technician. The service technician is allowed to
perform the normal routine care of your furnace. He can detect
potential problems and make corrections before trouble
develops. Preventative maintenance of this type will allow the
furnace to operate with minimal concerns to the homeowner
and will add years of comfort.
