2. Flue gas from the boiler is properly vented; (refer to Section 3.5)
3. Gas connection has been made correctly. Double Check that Natural Gas is piped to Natural Gas inlet and
Propane Gas is piped to Propane inlet. The gas lines have been pressure tested for leakage and the lines purged
of air. Make sure all required vents have been installed. (refer to Section 3.6)
4. Water connections are complete and the boiler and system have been filled and purged of air. (refer to Section
3.7)

to their proper settings.
NOTICE! If the expected error code(s) do not appear, call for qualified service.
3.9.1 Test of Ignition Safety System
Test the ignition system safety shutdown as follows:
1) Cycle the boiler on by generating a heat request. (See Section 3.10)
2) Place the boiler in operation at the high fire setting.
3) Smoothly close the downstream manual isolation valve to reduce the gas flow and cause flame failure.
4) The display will show LOCKING FLAME FAILURE indicating a flame failure. The lockout will remain until the
control is reset.
After completing this test, turn off the boiler and open the downstream manual isolation valve and turn the boiler back
on.
