SPARK IGNITION TRANS-
FORMER (XFORMER) (T1)
The spark ignition transformer resides
on the furnace control (older genera-
tions of the modulating furnace have the
spark transformer mounted to a sepa-
rate ignition control). The transformer
provides spark energy at approximately
60 hz frequency and a minimum of
12KV. The transformer can be seen in
Figure 61.
DO NOT ROUTE THE ORANGE IGNIT-
ER WIRE WITHIN 2
ⴖ
OF THE GAS
VALVE. DOING SO COULD CAUSE
FAILED IGNITIONS AND LOSS OF
HEAT.
R-J11 CONNECTOR (J-11)
DO NOT CONNECT A TELEPHONE
OR PHONE LINE TO THE CONNEC-
TOR (JACK) AT POSITION J-11.
DOING SO COULD CAUSE
IRREPRABLE DAMAGE TO EITHER
THE FURNACE CONTROL (I.F.C.) OR
THE TELEPHONE (OR TELEPHONE
LINE) OR BOTH.
This connector is used to program the
furnace control at the factory. It can
also be used to connect a field service
diagnostic tool. Unfortunately, this tool
was not available at the time of this
publication but should be available in
the future. Otherwise, this connection
is not to be used in the field. It should
never be connected to a telephone line
or a telephone. Doing so could dam-
age the furnace control or the tele-
phone (or telephone lines) or both.
COMMUNICATIONS
NETWORK CONNECTION
These connections are used when
installing a communicating thermostat
specified for use with this furnace.
Further, normally, thermostat connec-
tions will not be made at the 24 V
Thermostat Inputs when using a com-
municating thermostat. (Except under
one special circumstance where a
communicating thermostat and non-
communicating condenser are used.
See Figure 59 and the section of
this document titled SPECIAL CON-
FIGURATION – COMMUNICATING
THERMOSTAT AND FURNACE
WITH A NON-COMMUNICATING
CONDENSER.)
The terminal labeled “1” on the fur-
nace control connects directly to the
terminal labeled “1” on the thermo-
stat and “1” on the condenser. The
remaining connections follow the
same pattern.
Follow the wiring diagram in Figure
59 for connections of the communi-
cations network.

WARNING: Do not route the orange
igniter wire within 2

Noise from the wire could cause
failed ignition and loss of heat.
