Wiring
!
WARNING: Risk of Explosion or Fire.
Locate all safety, limit, and operating controls in
series with the thermostat terminal (TH) on the
ignition control. Improper installation may cause gas
leaks, which can lead to an explosion or fire and
may result in severe personal injury or death.
Refer to Figure 2 through Figure 5 for wiring diagrams.
All wiring should be in accordance with the National
Electrical Code (NEC) and all other local codes and
regulations.
Check the voltage rating marked on the control and
make sure it is suited to the application. Use a Class 2
transformer capable of providing 24 VAC under
maximum load, including valves. A transformer having
excessive primary impedance due to poor coupling
affects the ignition potential.
The high-voltage spark transformer cable is noise
suppression (resistive) type rated for at least 15kV and
must not be in continuous contact with a metal
surface. Use standoff insulators. Ensure that the flame
sensor wire and high voltage spark transformer cable
are separated from one another by a minimum of
1/4 in. (6.35 mm) and are not wrapped around any
pipe, other wiring, or accessories.
The control is supplied with a jumper wire between
Sense and Internal terminals and is ready for internal
(one rod) flame sense. With the jumper in, flame is
sensed through the high voltage spark wire. The
jumper must be removed for external (two rod) flame
sense and the sense electrode wired to the Sense
terminal.
Note: A shorting plug that jumpers pins 2 and 3 of the
damper connector is supplied with the control. The
shorting plug must be used if a vent damper is not
used. When a vent damper has been connected and
power turned on, an internal fuse in the control will
blow and the control will only operate with a vent
damper connected. Now you cannot disconnect the
vent damper plug and put back the shorting plug. The
ignition control will not work.
!
WARNING: Risk of Electric Shock.
Before applying power to the control, connect the
high voltage cable to the spark transformer terminal
and spark electrode (pilot burner assembly). Verify
the ground wire is attached to the pilot burner and
the control ground terminal strip. Failure to follow
this procedure can cause electric shock and may
result in severe personal injury or death.
