Profire D/LND

Costly downtime or delays can be prevented by systematic checks of actual operation against the normal

sequence to determine the stage at which performance deviates from normal. Following a set routine may possi-

bly eliminate overlooking an obvious condition, often one that is relatively simple to correct.

If an obvious condition is not apparent, check each continuity of each circuit with a voltmeter or test lamp. Each

circuit can be checked and the fault isolated and corrected. In most cases, circuit checking can be accomplished

between appropriate terminals on the terminal boards in the control cabinet or entrance box. Refer to the wiring

schematic supplied for terminal identification.

Never attempt to circumvent any of the safety features.

6.2 — Emergency Shutdown

1. In case of an emergency, shut down the burner by turning the “ON-OFF” switch to the “OFF” position.

2. Turn the fuel selector switch to the “OFF” position.

3. Shut off the main manual fuel shutoff valves on the fuel supply line.

4. The unit can also be shut down with the main electrical power disconnected. Inspect the burner carefully and

troubleshoot before restarting the unit.

Follow instructions in Chapter 3 for starting and operating.

The cause for loss of flame or any other unusual condition should be investigated and corrected before attempting to

restart. Failure to do so may result in serious personal injury or death.

Do not repeat unsuccessful lighting attempts without rechecking the burner and pilot adjustments. Failure to do so

may result in boiler damage and/or serious personal injury or death.

Do not re-light the pilot or attempt to start the main burner, either oil or gas, if the combustion chamber is hot and/or

if gas or il vapor combustion gases are present in the furnace or flue passages or when excess oil has accumulated.

Promptly correct any conditions causing leakage. Failure to follow these instructions could result in serious personal

injury or death.
