NOTES:
1. CONNECT Y-TERMINAL AS SHOWN FOR PROPER COOLING OPERATION.
2. IF ANY OF THE ORIGINAL WIRE, AS SUPPLIED, MUST BE REPLACED,
USE SAME TYPE OR EQUIVALENT WIRE.
3. PROPER POLARITY MUST BE MAINTAINED FOR 115-VOLT WIRING.

location. When reinstalling ignitor, use care to insure all wiring is
away from the burners and is not touching the bottom of the sheet
metal enclosure.
Step 7—Electrical Controls and Wiring
NOTE; There may be more than 1 electrical supply to the unit.
The electrical ground and polarity for 115-v wiring must be
maintained properly. Refer to Fig, 15 for field wiring information
and to Fig. 17 for unit wiring information. If the polarity is not
correct, the microprocessor control will shut off the gas flow
shortly after completion of the ignition trial period. The control
system also requires an earth ground for proper operation of the
niicroprocessor.
The 24-v circuit contains an automotive-type, 3-amp fuse (FUl)
located on the main control board. (See Fig. 16.) Any direct shorts
during installation, service or maintenance may cause this fuse to
"blow." If fuse replacement is required, use only a fuse of identical
size.
With power disconnected to the unit, check all electrical connec­
tions for tightness. Tighten all screws on electrical connections. If
any smokey or burned connections are found, disassemble the
connection, clean all parts, strip wire, and reassemble properly and
securely.
Reconnect electrical power to the unit and observe unit through 1
complete operating cycle. Electrical controls are difficult to check
without proper instrumentation; if there are any discrepancies in
the operating cycle, contact your dealer and request service.
A CAUTION
The unit must not be installed, operated, and then turned off
and left off in an unoccupied structure during cold weather
when the temperature drops to 32° F and below. Freezing
condensate left in the furnace will damage the equipment.
If the furnace will be off for an extended period of time in a
structure where the temperature will drop to 32° F or below,
winterize as follows;
1. Mix a solution of equal amounts of ethylene glycol (Prestone
II antifreeze/coolant or equivalent) and water.
2. Turn OFF electrical supply to furnace.
3. Remove control access door.
4. Disconnect drain tube from bottom of inducer outlet box/el-
bow.
5. Insert funnel in drain tube and pour antifreeze/water solution
into furnace until it is visible at point where condensate enters
open drain.
6. Reconnect drain tube to outlet box/elbow.
7. Replace control access door.
