After a failure to detect
the fl ame during ignition,
the control will retry the
specifi ed number of times.
After the maximum failed
attempts, this fault is
declared.
Soft
Check the igniter wire harness.
Check igniter 120Vac voltage
supply during the ignition time.
Check the ignition rod. If it looks
dirty clean it using isopropyl alcohol
and a clean cloth.
Check the high voltage wiring
connection between igniter and

E34
Proportional Valve
(PV) Response
Too Slow.
The closed loop control
of the proportional valve
is not functioning properly
(control error) or the valve
is responding slowly (valve
failure).
Soft
Check the proportional gas valve wire
harness, change the Control Board,
change the gas valve assembly
E35
Repeated Flame
Loss Fault.
Low Gas Inlet Pressure.
Low Water Flow Rate
Soft
Clean or change the water fi lter.
Check the Flame Sensor wire
harness.
Check line gas pressure. If it is above
5” WC check the Flame Sensor
and if it looks dirty, clean it up using
isopropyl alcohol and a clean cloth.
Change the Flame Sensor.
Change the Control Board.

E36
Calibration error.
Calibration sequence
incomplete because end
of “call-for-heat” during
the calibration time, or
calibration sequence not
initiated because of lack of
“call-for-heat”, or the unit
has been never calibrated
or Calibration is successful
but DIP switch 4 not set to
“normal”.
Soft
Unplug the power cord, check the
DIP switch 4 position and put it in
ON position.
Increase the set point so that a
“call-for-heat” occurs.
Drain the tank in order to lower the
water temperature so that a “call-
for-heat” is generated.
Set DIP switch 4 to OFF position.
Recalibrate the unit.
Change the Control Board.
