♦Permissible limits of the voltage range at which the unit will operate
satisfactorily.
tTime-delay fuse is recommended.
ifLength shown is as measured one way along wire path between unit
and service panel for maximum 2% voltage drop.
Make all electrical connections in accordance with the
National ElectriceJ Code ANSI/NFPA 70 and local codes or
ordinances that might apply. For Canadian installations, all
electrical connections must be made in accordance with
CSA C22.1 Canadian Electrical Code, or authorities having
jurisdiction.
A WARNING
The cabinet must have an uninterrupted or unbroken
ground according to National Electrical Code, ANSI/
NFPA 70 and Canadian Electrical Code, CSA C22.1 or
local codes to minimize personal injury if an electrical
fault should occur. This may consist of electrical wire or
conduit approved for electrical ground when installed in
accordance with existing electrical codes. Do not use
gas piping as an electrical ground.
The auxihary junction box can be moved to the right-hand
side of the furnace when a right side power supply is
desired. Remove the two screws holding the auxihary junc
tion box. Mount the junction box on the right-hand side of
the furnace (holes have been predrüled in casing). The
blower door interlock switch must also be moved to the
right side of the furnace due to the length of the wiring har
ness. When moved, tuck the wiring harness behind the clip
provided to keep extra wire lengths out of the way.
NOTE;
Proper polarity must be maintained for 115-VAC
wiring. If polarity is incorrect, the microprocessor wiU shut
off gas flow shortly after the completion of ignition trial
period.

B. 24-Volt Wiring
Make field 24-volt connections at the 24-volt terminal strip.
See Fig. 8. Connect terminal Y as shown in Fig. 8 for proper
cooHng operation. Use only AWG No. 18, color coded cop
per thermostat wire.
C. Accessory
1. Electronic air cleaner
Two screw terminals (EAC-1 and EAC-2) are provided
for electronic air cleaner connection. The terminals are
energized with 115-VAC, 1 amp maximum during
blower motor operation.
2. Humidifier
Screw terminals (HUM-1 and C) are provided for 24-
VAC humidifier connection. The terminals are ener-
, gized with 24-VAC, 0.5 amp maximum during heating
blower motor operation.
VII. VENTING
These instructions are to be used only for 58PAV Furnace
vent systems. These furnaces are equipped with induced-
combustion blowers, and are classified as Category I type
furnaces in accordance with ANSI/A.G.A. Z21.47 Central
Furnace Standards. Category I furnaces use nonpositive,
noncondensing vent systems, and may be connected to Hned
masonry chinmeys sized and installed per the National Fuel
Gas Code.
