Perform Test of Low Gas Pressure Switch

Test the low gas pressure switch as follows:
1. With the boiler running increase the low gas pressure setpoint until a lock
out is annunciated.
2. Reset the switch to normal level, re-start the boiler.

Perform Test of High Gas Pressure Switch

Test the high gas pressure switch as follows:
1. Close the downstream main gas cock and start the boiler.
2. Once the trial for ignition period is reached, the main gas valve will open,
pressurizing the line. This will trip the high gas pressure switch.
3. Manually reset the high gas pressure switch after it trips.

Perform Test of Air Switch

Fire the boiler and test the air switch as follows:
1. At low re turn the adjustment on the switch clockwise until the switch
trips and the boiler shuts down.
2. Back out the adjustment to previous position.

Test of High Back Pressure Switch

Fire the boiler and test the high back pressure switch as follows:
1. At high re turn the adjustment on the switch counter clockwise until it
opens and the boiler shuts down.
2. Turn the adjustment in two turns.

Normal Operation of the Boiler

Under normal operating circumstances, this boiler functions as a fully automatic
appliance. The automatic control senses the water outlet temperature and
res the boiler when heat is needed by the system. Additionally this boiler may
function as part of an integrated building management system.
Outlet water temperature, fan speed and set point are displayed on the SOLA
touch screen display on the front of the boiler. Figure 10 shows a sample screen
display on the SOLA control.
