Test
Point
Component Results / Optimal Condition
TP5 8v Power
Supply
The voltage should be between 7.9 and 8 volts. A lower voltage indicates
a problem with the voltage supply to the logic of the control board.
TP6
Power to
Control Board
This is the battery voltage supplied to the control board; it should be
between 11 and 15 volts.
TP7 Power to
Flame Sensor
The power to the flame sensor should read between 11 and 15 volts (same
as battery voltage).
TP8 Cycling
Aquastat
The voltage will be between 4.8 and 5 volts if the heater is cycling (cycling
aquastat is open), and 0 if the cycling aquastat is closed.
TP9 Overheat
Aquastat
The voltage will be 0 volts if an overheat condition is occurring or has
occurred in the past two minutes (overheat aquastat is open). The voltage
will be between 4.8 and 5 volts if the overheat aquastat is closed.
TP10 Voltage Fault The voltage will be 0 volts if there is no voltage fault, and between 4.8 and
5 volts when there is a voltage fault.
TP11 Remote
Switch
The voltage will be 0 volts when the remote switch is off, and between 4.8
and 5 volts when the switch is on.
TP10 Reset The voltage will be 0 volts when the reset button is pressed, and between
4.8 and 5 volts when the reset button is not engaged.
TP13
Thermostats
or Domestic
Water
The voltage will be 0 volts when the thermostat or domestic water system
calls for heat and between 4.8 and 5 volts when heat is not called for.
TP14 Blown Fuse Blown fuses for the burner, pump, or cabin fans will show a voltage of
between 4.8 and 5 volts. Good fuses will show 0 volts.
10.21 Reduced Output
The heater may run without faulting, but at a reduced output. If
this is noticed, it could be caused by the following:
High altitude
Dirty nozzle
Defective regulator
Too small a nozzle
Poor water circulation
Ash deposit in combustion chamber
10.22 Smokey, Smelly Exhaust
The heater may run without faulting, but you may experience
signs of soot, exhaust smoke and/or a pungent smell. This is
