TEST OF IGNITION SAFETY SYSTEM SHUTOFF
Test the ignition system safety shutoff as follows:
1. Shut the pilot ball valve.
2. Close the last gas valve between the inlet to the burner and the butterfly valve.
3. 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 and temperature are satisfied, the blower will run and
pre-purge the heater.
4. 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 flame safeguard
(pilot and main).
5. With no flame established, the flame safeguard will not receive a flame signal from the scanner.
6. After 4 seconds, the flame safeguard programmer will assume a “Flame Failure” condition and
go to a “lockout” mode. Lockout will require manual reset of the flame safeguard.
7. After completing this test, open the gas valve.

CYCLE TESTING
The heater should be cycled tested and automatically allowed to go through its normal starting
sequence several times to verify that all components are functioning properly. This will also verify
that combustion is set properly so that heater light off has a smooth transition from ignition to main
flame.
A minimum of 10 cycles should be met without any flame failures, with combustion readings
comparable to the factory test fire sheet and no interlocks causing the heater to shutdown.
