1. Remove the black plug/connector from the main gas valve (it is held on
with a central screw).
2. With the main gas cock (inlet manual gas valve) open, the burner should
be cycled on. After all the safety limits such as gas pressure, water  ow and
temperature are satis ed, the blower will run and pre-purge the boiler.
3. Once the purge is complete (30 seconds), the ignition transformer will be
energized. There will be a 4 second trial for ignition period. During this
period, indicator lights on the  ame safeguard (pilot and main)
4. The main gas valve will not open because there is no power to the valve
due to the disconnected wires. Hence, no  ame will be established and the
 ame safeguard will not receive a  ame signal from the UV scanner.
5. After 4 seconds, the  ame safeguard programmer will assume a “Flame
Failure” condition and go to a “lockout” mode. Lockout will require manual
reset of the  ame safeguard.
6. After completing this test, turn o the boiler and reconnect the wires to
the main gas valve.
