Test of Ignition Safety System

Test the ignition system safety shuto as follows:
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 (15-30 seconds), the ignition transformer will
be energized. There will be a 4 second trial for ignition period.
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. The control will allow one retry before locking
out.
6. After completing this test, turn o the boiler and reconnect the wires to
the main gas valve.
Perform Test of Low Water Cut Off
This boiler is equipped with a ow switch type low water cut-o in the outlet
nozzle. Once the boiler is full of water the following test can be accomplished:
1. Turn the boiler o .
2. Turn system pump o .
3. Turn the boiler back on. The "Hold 63 LCI O " will annunciate, after a call
for heat from the Temperature Control. The boiler should not start until the
pump is started.
4. Perform appropriate test for any external or factory-installed probe-type
low water cut-o .

Perform Test of Limit Controls

Fire the boiler and test the high limit control as follows:
1. Access the High Limit screen of the SOLA control.
2. Alter high temperature limit to a value lower than the anticipated loop
temperature. Turn the boiler on. Water temperature will rise until the
boiler locks out. This condition has to be manually reset. Alter the high
limit cut o temperature to normal level, typically 10-20 degrees above set
point.
