HIGH FLUE PRESS FLU
PUMP ON
FLU indicates excessive flue pressure. This
code resets automatically after the high
pressure condition is resolved. The second
line indicates pump status.
1. Assure the flue is not blocked.
2. Check the switch wiring by applying a jumper in place
of the switch. If the code clears with the jumper in place,
REPLACE the flue switch and connect the wires to the
new switch BEFORE running boiler.
WARNING:
Do not use jumper to remedy an FLU error. Faulty switch MUST be replaced. Failure to follow this instruction could result in
serious personal injury or death.
FLUE TEMP HIGH E07
PUMP OFF TIME
E07 indicates the flue sensor temperature
is excessive and above 210
o
F. When E07 is
displayed the boiler will not respond to a
demand for heat and begin to modulate
down on vent temp rather than supply temp.
During reduced modulation, the display will
show VENT RED MODULATION, and the
second line will alternate between PUMP ON
TIME and the actual vent temperature.
When the flue temperature decreases below
194
o
F, the display will return to normal and
allow the boiler to respond to a heat demand.
1. Check the flue for obstructions and any sign of damage,
especially signs of excessive heat. Repair as necessary.
2. Run the boiler and check the flue temperature with
an external thermometer. If the flue temperature on the
thermometer does not agree with the flue temperature
displayed in the status menu, inspect the wiring to the flue
temperature sensor in the boiler and repair as necessary.
If the wiring is intact replace the flue sensor.
3. If the flue temperature is excessive on the status menu
and the test thermometer reads the same, check and
adjust combustion controls on the boiler.
LINE VOLTAGE E19
PUMP OFF
E19 indicates the line voltage frequency is
out of range. This could happen if the boiler
is being powered from a small gasoline
powered generator that is overloaded or not
functioning correctly.
Inspect power wiring to the boiler and repair as necessary.
If connected to line voltage, notify the power company.
If connected to an alternate power source such as
a generator or inverter, make sure the line voltage
frequency supplied by the device is 47 - 62.5 Hz.
BURNER TEMP BLOCK E28
PUMP ON TIME
This error indicates the burner sensor has
exceeded 199
o
F. The burner will re-fire once
the burner temperature drops below 181
o
F.
If this occurs more than five times in ten
minutes during a single heat demand, an F28
lockout code is generated.
1. Check sensor by turning off the gas and allowing the unit
to go through pre-purge and post purge cycles. While air is
flowing through the burner check the burner sensor value
on the display. This value should similar to the current
intake air temperature. If this value is much different than
the current intake air, check sensor resistance and wiring.
If resistance values are out of range replace sensor.
2. If sensor is ok, check combustion, often a rich
combustion setting elevates burner temperatures. Ensure
there are no blockages on either the intake or the exhaust.
Confirm the combustion is set to proper CO2 numbers,
especially on low fire. After adjusting combustion, re-
start the boiler and observe the burner temperature on
the display. This should be done both on high and low fire.
