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
• Check periodically if the Ground Fault has tripped and needs to be
reset
Water Temperature Probe
Principles
The water temperature probe communicates with the controller to control the combustion air to its proper
setting.
1) At the controllers’s
low
setting it will turn the combustion air blower(s
) on
, re-igniting
the fire.
2) At the controller’s
high
setting it will turn the combustion air blower(s)
off
, extinguishing the fire.
3) The difference between the highest temperature of the water and the
lowest temperature of the water is 20 degrees Fahrenheit. From the
factory, this control is set at approximately 185 degrees Fahrenheit
for the high and 165 degrees Fahrenheit for the low.
Adjustments
1) No adjustments to the controller settings can be made.
Removal and Replacement
1) Turn off the main power supply to the HEATMOR™.
2) Pull the thermocouple straight out of the well.
3) Disconnect the thermocouple wire connection from the controller and re-wire the new thermocouple.
4) Route and replace the new thermocouple into the well with silicone.
5) Turn on the power.
High Water Temperature Safety Shutoff Control
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 blower and the front light if an excessive water temperature be reached.
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
would be re-activated. The combustion air blowers will not come back on until the low water
