The combustion process will
continue to operate in this
manner until one of the following
occurs:
A.) The VDC / VAC Control
Thermostat, which senses
coolant temperature, reaches the
preset temperature of
approximately 190 (+/- 5)
degrees Fahrenheit
.
NOTE:
If process "A" occurs, the
Heating Status and Diesel-
Burner Status lights on the
Electronic Controller will go
OFF; reference Figure 6.
B.) The Aqua-Hot’s Diesel switch
is turned OFF.
NOTE:
If process "B" occurs, the Diesel
switch’s Indicator Light, on the
Switch Panel (reference Figure
2), will go OFF along with the
Heating Status and Diesel-
Burner Status lights on the
Electronic Controller; reference
Figure 6.
SUMMARY:
The Aqua-Hot’s Diesel-
Burner is in stand-by
mode anytime the operator
moves the Diesel switch
(reference Figure 2) to the
ON position. The Diesel-
Burner will then
automatically ignite and
maintain the coolant
temperature in the Aqua-
Hot’s Boiler Tank without
additional involvement
from the operator.
1.) The Motor (#2) will
shut-off once the three (3)
minute purge-cycle has
expired.
-THEN-
2.) The Aqua-Hot’s Diesel-
Burner will automatically
turn back ON once the
coolant temperature
reaches the preset
temperature of
approximately 160 (+/- 5)
degrees Fahrenheit.
The Motor (#2) will
continue to run for
approximately three (3)
additional minutes. This
process is refered to as
the purge-cycle, which
cools down the heater’s
internal components
and purges the
Combustion Chamber
(#11) of any residual
exhaust gases.
Once the heater switches
OFF, thermostatically or
manually, the Fuel
Solenoid (#6) closes,
which interrupts the supply
of diesel fuel to the Fuel
Nozzle (#9).
NOTE:
When the Aqua-Hot’s
Diesel-Burner is switched
OFF, by the VDC / VAC
Control Thermostat, the
following process will take
place:

Information
SECTION 3: OPERATING INSTRUCTIONS
3.6 Precautions
WARNINGS:
• The Aqua-Hot's Exhaust is HOT!
• DO NOT park in areas where dry conditions exist underneath the
vehicle, as a fire may result (e.g., in a dry, grassy field).
• DO NOT operate the Aqua-Hot’s Diesel-Fired Burner inside an
enclosed building.
•The Heater should be switched OFF when refueling.
CAUTION: DO NOT operate the Diesel-Burner and/or the Electric
Heating Element(s) without the water and antifreeze solution in the Aqua-
Hot’s Boiler Tank. Failure to do so will cause serious damage to the
Heater.
