After installation of the burner system components is complete,
the following steps should be followed in order to prepare for
adjustment:
1. Set the air flow switch so that it drops out at 20% below the
maximum pressure of the combustion air blower.
2. Set the low gas pressure switch at 20% below the gas
pressure measured at the inlet to the main gas valve train.
3. Set the high gas pressure switch at 20% above the gas
pressure measured at the inlet to the main gas valve train.
4. Close all manual valves feeding the burner.
5. Try to ignite the burner before the purge and other
timers have finished their cycles. Make sure that the flame
monitoring system indicates a flame failure.
6. Trip out the pressure switches and other limit interlocks.
Make sure that the main gas valve train closes.
Danger:
If simulated limits or simulated flame failures do
not shut down the fuel system within the required
failure response time, immediately correct the
problem before proceeding.
