TROUBLESHOOTING

XFyre Error Codes

If any of the sensors detect an abnormal condition or

an internal component fails during the operation of the

XFyre, the display may show an error code. This code

may either be the result of a temporary condition in

which case the display will revert to its normal readout

when the condition is corrected, or it may be the result

of a condition that the controller has evaluated as not

safe to restart the unit. In this case, the unit control will

be locked out, requiring the maintenance person to

manually reset the control by pressing and releasing

the RESET key.

Heater Errors

When an error condition occurs, the controller will dis-

play an error code on the display module. These error

codes and several suggested corrective actions are

included in the XFyre Fault Text section on the follow-

ing page.

Heater Faults

1. When a fault condition occurs, the controller will

flash a red light on the PIM and display the error

code on the user interface. The alarm output will

also be activated. Most fault conditions will also

cause the boiler pump to run in an attempt to cool

the unit.

2. Note the error code, either through the flash code

on the PIM and/or from the Toolbox menu on the

user interface, and reference the explanation of

the fault along with troubleshooting steps in the

XFyre fault text section.

10. Observe several operating cycles for proper oper-

ation.

11. Set the boiler thermostat to desired temperature.

12. Review all instructions shipped with this boiler with

owner or maintenance person, return to envelope

and give to owner or place the instructions inside

front panel on boiler.

a. There are no loose connections or that the

service switch is off.

b. High temperature limit switch or manual-reset

high limit is not tripped.

c. Thermostat is set above water temperature.

d. Gas is on at the meter and the boiler.

e. Incoming dynamic gas pressure to the gas

valve is NOT less than 4.0 in. WC for natural

gas or propane gas.

To Turn Off Gas To Appliance
