The burner sounds will change and the Power Unit voltage will rise more rapidly.
7.
Continue to hold down the button
.
If the flame goes out, close the Burner Run Valve to re-establish the flame and then re-open
the valve slowly.
WARNING!
Do not allow the burner to operate while the Burner Run Valve is closed for
more than 5 minutes. Open the Burner Run Valve as soon as the flame is
audibly burning.
8.
Observe the voltmeter while continuing to hold the button down. Five minutes after opening the
Burner Run Valve, or as soon as the Power Unit voltage reaches 14 Volts, slowly release the
Automatic Shut-off Valve.
The internal electromagnet should hold the Automatic Shut-off Valve open.
If the valve does not stay open, immediately press the button again and hold it down for one
more minute, then try to release it again. If the valve still does not stay open, refer to
Section 5.8
to troubleshoot the Automatic Shut-off system.
Once the burner is started, proceed to Heat Up and Power Adjustment in the next section.
If the operation of the burner must be stopped, turn off the fuel supply at the external valve. Then
close the Burner Run Valve. The Automatic Shut-off Valve will close when the burner thermocouple
cools down.
WARNING!
Proceed to the Heat Up and Power Adjustment section as soon as the automatic
shut-off valve remains open. Failure to do so may overheat the Power Unit.
4.1.3
HEAT UP AND POWER ADJUSTMENT
It is normal for the heat pipes to make a crackling sound as they start to operate. Once the burner is
operating, the Power Unit voltage will climb rapidly to
the TEG’s voltage setpoint (set to 27.1 V at the
factory).
Continue to monitor the Power Unit voltage at terminals 6(+) and 4(-) of TB-1 for about an hour. The
voltage should remain at the voltage setpoint. Adjust the Power Conditioner if needed.
During heat up, the current will initially rise rapidly and then slow down as soon as the TEG
approaches its operation point.
9.
Fifteen minutes after ignition, check the tip of each heat pipe to check if they are getting warm.
If one or more heat pipes are not getting warm, check them again after an additional 10
minutes. If they still remain cold up to 2 inches (50 mm) from the tip, troubleshoot the
cooling system as outlined in
Section 5.3.
NOTE:
If it’s too cold or too windy to assess the temperature of the heat pipes, check the
cooling fins instead. If all the fins on a heat pipe are at about the same temperature,
then the heat pipe is working well.
