Double Electrical Outlets at Rear
Principles
To provide a live source of 115V power to power pumps,
trouble lights, etc.
Maintenance
• Do not overload the circuit
• Keep the outlets clean
High Water Temperature Safety Shutoff Control
(Aquastat on the right)
Principles
The correct name is an “aquastat.” It is referred to as an
aquastat because it measures the temperature of water (aqua
means water). It is sometimes referred to as a thermostat, but
thermo means air. It does not measure the temperature of air.
The High Water Temperature Safety Shutoff Control turns off all
electrical power to the combustion air blowers and the front light
if an excessive water temperature is reached. To provide added
safety and notication, when a high water temperature is reached,
this aquastat will send electrical power to the “red wire”. The red
wire leading from the HEATMOR™ back to the power source
can be installed so the electrical power will sound an alarm or
will override the comfortable heat settings within the heated
building. By starting heating appliances in the building, heat
will be drawn off the HEATMOR™, dumped into the building,
creating an elevated temperature environment in the building,
and hence a notication of an unusually high water temperature
within the HEATMOR™. By removing this excess heat from the
HEATMOR™, a “boil” will normally be avoided.
Operation
• From the factory, this control is set at 200 degrees
Fahrenheit. When the water temperature within the water
jacket lowers to 195 degrees Fahrenheit; the electrical
circuit to the main combustion air blower(s) would be re-
activated. The combustion air blowers will not come back on
until the low water temperature is reached.
• There is no need to make any adjustment. Leave it set at
200˚Fahrenheit.
