Normal Operation
4-L2 Line voltage at Terminal 4.
6-L2 Line voltage at Terminal 6.
20-L2 Line voltage at Terminal 20.
7-L2 1. Burner motor (fan or
blower) starts.
2. Line voltage at Terminal
7 within 10 seconds.
—
Ignition spark (if ignition
transformer is connected to
Terminal 10)
—
1. Ignition spark (if ignition
transformer is connected to
Terminal 8).
2. Automatic pilot valve opens (if
connected to Terminal 8).
NOTE: Refer to wiring diagram of
system being tested.
—
Same as test no. 6 for connections
to Terminal 8. If using direct spark
ignition, check the first stage fuel
valve(s) instead of the pilot valve.
—

If using direct spark ignition on a
model with intermittent pilot on
Terminal 21, check the optional
second stage fuel valve, if used.
—
Alarm (if used) turns on.
18-L2 Firing rate motor drives open; zero
volts at Terminal 18 after motor
starts driving open.
18-L2 Firing rate motor drives closed; line
voltage at Terminal 18 after motor
is in Low Fire position.
19-L2 Firing rate motor drives open; line
voltage at Terminal 19 after motor
is in High Fire position.
19-L2 Firing rate motor drives closed;
zero volts at Terminal 19 after
motor starts driving closed.
—
1. Raise setpoint of Series 90
controller—firing rate motor
should drive toward open.
2. Lower setpoint of Series 90
controller—firing rate motor
should drive toward closed.
