ProFire Q Series Manual
If an obvious condition is not apparent, check the 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 terminal 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
In case of emergency, shut down the burner by turning the ON-OFF switch to the “OFF” position. Turn the fuel
selector switch to the “OFF” position. Shut off the main manual fuel shut off valves on the fuel supply line. The unit
can also be shut down with the main electrical power disconnect. Inspect the burner carefully and troubleshoot before
re-starting 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 adjustments. Damage to the boiler or serious
personal injury or death may result.
Do not attempt to start the main burner if the combustion chamber is hot and/or if gas is present in the furnace or flue
passages. Promptly correct any conditions causing leakage. Failure to follow these instructions could result in serious
personal injury or death.
