CAUTION

After checking controls by manual
adjustment, make sure they are always
reset to their proper settings.

Test of Ignition Safety System

Test the ignition system safety shutoff 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 fl ow and
temperature are satisfi 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 fl ame will be established and the
fl ame safeguard will not receive a fl ame signal from the UV scanner.

5. After 4 seconds, the fl ame safeguard programmer will assume a “Flame

Failure” condition and go to a “lockout” mode. Lockout will require manual
reset of the fl ame safeguard. The control will allow one retry before locking
out.

6. After completing this test, turn off the boiler and reconnect the wires to

the main gas valve.

Perform Test of Low Water Cut Off

This boiler is equipped with a fl ow switch type low water cut-off in the outlet
nozzle. Once the boiler is full of water the following test can be accomplished:

1. Turn the boiler off .

2. Turn system pump off .

3. Turn the boiler back on. The “Hold 63 LCI Off ” 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-off .

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 off temperature to normal level, typically 10-20 degrees above set
point.
