Prepare for Start Up/Adjustment
After installation of the burner system components is complete, the
following shall be followed to prepare for adjustment:
Set the air flow switch so that is drops out at 20% below the
maximum pressure of the combustion air blower.
Set the low gas pressure switch at 20% below the gas
pressure measured at the inlet to the main gas valve train.
Set the high gas pressure switch at 20% above the gas
pressure measured at the inlet to the main gas valve train.
Close all the burner shut-off valves.
Try to light a burner before the purge and other timing relays
have finished their cycles. Verify that the flame monitoring
system indicates a flame failure.
Trip pressure switches and other limit interlocks. Verify that
the main gas valve train closes.
DANGER:
If simulated limits or simulated flame failures do not shut
down the fuel system with the required failure response time,
immediately correct the problem and retest before proceeding.
