Perform Test of Ignition Safety System
Test the ignition system safety shuto as follows:
1. 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 satised, the blower will run and pre-purge the boiler.
2. 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).
3. 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.
4. 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.
5. After completing this test, turn o the boiler and reconnect the wires to
the main gas valve.
Perform Test of Low Water Cut Off
Once the boiler is full of water the following test can be accomplished:
1. Turn the boiler on, this will start the Call for Heat sequence.
2. Press and hold the Low Water Test button for 3 seconds. The Low Water
light should illuminate and the boiler should shut down the Call for Heat
sequence.
3. Reset the Low Water condition by pressing the Low Water reset button and
the LMV Reset button. Boiler should start the Call for Heat sequence again.
4. Perform appropriate test for any secondary Low Water controls.
