Corrective Action(s)

IGNITION 
FAULT

Boiler went through 5 ignition 
attempts and never detected 
flame or flame sense value 
never reached minimum 
threshold for boiler model.

Automatically resets after 1 hour 
or can be reset by performing 
manual reset on boiler.

Check condensate trap for blockage allowing condensate to accumulate 
inside heat exchanger.
Check ignition cable connection.

Fouled, worn, bent, or faulty igniter.   
Fouled igniters can be cleaned for additional use with steel wool. 
Worn or badly fouled igniters should be replaced with the proper repair 
part. 

Igniter rods should be parallel with a 3.5 mm (0.138 in) spark gap.

NOTICE:  Thin white deposits on the igniter are typical, but brown or 
black deposits could be the result of flue gas recirculation. Thoroughly 
inspect the venting system and termination for the possibility of leakage 
or flue gas feedback into the air line.

Dirty burner and/or heat exchanger will cause high back pressure and 
poor ignition.  
Follow procedure in maintenance section of this manual to clean burner 
and heat exchanger. Visual inspection of flueways may not be sufficient 
to diagnose condition. 

Check combustion settings on high and low fire and adjust per setup 
instructions if necessary.

Check incoming gas pressure with boiler off and at high fire.  Adjust 
within limits on rating label.

Verify correct boiler model and altitude is selected in control and correct 
elevation must be entered when operating above 2,00 feet.

Check ignition cable resistance.  Should measure 1000 Ohms (+/- 50 
Ohms).

Check for flue pipe and intake pipe restrictions or blockage.

Check burner fasteners and gaskets.

Check venturi gaskets and proper venturi. (Propane models use different 
venturi’s).

AIR PRESSURE 
Switch Open

Occurs when Air Pressure 
connection is open.

Reset using Manual Reset 
screen on display.
High pressure in the exhaust 
pipe or high vacuum in the 
boiler intake or cabinet has 
caused the air switch to open. 
The switch is closed in normal 
operating conditions.

Check boiler size selected in control against boiler rating label.  Correct if 
necessary to select the proper boiler size.

Check exhaust and intake pipe for restrictions or blockage.

Check condensate drain for blockage. If condensate is unable to drain 
out of the boiler it can begin to block the flow of exhaust gases. Clean 
the condensate collection area of the base and condensate trap. Refill 
trap with fresh water.

Check the P7 connection as seen on Figures 52, page 48 & 
Figure 53, page 50. Check the connections on the pressure switch.

GAS PRESSURE 
SW FAULT

Gas pressure switch is open 
(high or low).

Either the low gas pressure 
switch or high gas pressure 
switch has opened due to 
incorrect gas pressure being 
supplied to the boiler.  Remove 
front door of boiler and look at 
pressure switches.  The upper 
switch is the high gas pressure 
switch and the lower one is a low 
gas pressure switch.  Whichever 
switch has locked-out will 
have an indicator light on. 
Switches can be reset by 
pushing on plastic cover 
in the middle of the dial as 
indicated on the switch. 

 

 

Control will also need reset 
using display after gas pressure 
switch has been reset.

Check gas pressure at tee mounted behind gas pressure switches during 
high and low fire and boiler off.  Pressure should always be with limits on 
rating label.  Undersized gas supply pipes or regulators may cause low 
gas pressure issues while the boiler is operating and possibly high gas 
pressure when the boiler shuts down.

Insure the pressure regulator in the gas supply line is a lockup-type.

Ensure gas pressure switch settings are correct.   
Low Pressure Switch Setting = 2 inches H2O 
High Pressure Switch Setting = 14 inches H2O
