Control Thermostat: Diesel Burner
The Diesel Burner control thermostat is installed onto the
Aqua-Hot’s boiler tank and monitors the temperature of the
antifreeze and water heating solution to determine when it is
at operating temperature and when it requires heat. The Aq-
ua-Hot’s Diesel Burner is considered to be at operating tem-
perature between 175°F and 200°F.
Troubleshoot the control thermostat if one of the following
conditions has occurred:

There is a lack of hot domestic water and interior heat.

The Diesel Burner does not operate

Excessive Blue or white smoke is expelled from the ex-
haust.
Troubleshooting:
1. Turn the diesel-burner switch on the interior switch pan-
el on.
If the Diesel Burner comes on and runs, but there is still
a lack of hot water verify that the control thermostat is
operating within the proper operating temperature range.
A. Using a digital temperature sensor, place the probe on
the tank next to the thermostat. The proper
operating temperature for the diesel burner is
175°F - 200°F.
2.
If the Diesel Burner Does not come on and run:
A.
Verify that the temperature of the boiler tank has
fallen below the 175°F minimum operating temper-
ature by checking with a digital thermometer.
B.
Disconnect the control thermostat’s wires from their
connections, and, using an ohmmeter, check for
continuity.
If there is no continuity, follow the instructions in
this section for replacing the control thermostat.
If continuity exists, complete the following:
a.
Inspect the control thermostat’s wiring and
connections.
b.
Verify the Diesel Burner’s Controller is send-
ing power to the control thermostat.
