Test
4-L2 Line voltage at Terminal 4.
6-L2 Line voltage at Terminal 6.
17-L2 For VP applications. (Terminal 17)
16-L2 Line voltage at 16
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
— 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 or
MV2 for VP tests.
— Automatic main fuel valve(s) open.
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.
