Burnham boilers troubleshooting

The American brand Burnham is known in the market since the 1873. Its equipment is mainly used by organizations. It undergoes a strict technical control. The company strives to help its customers with maintenance and repair of equipment. There is a Customer Care Center. And here on our site, you can find a table of Burnham boiler troubleshooting system. It is shown below.

CONDITIONPOSSIBLE CAUSE
Display Blank, Fan off, LWCO lights off, no green power light on Sage2.1 ControllerNo 120VAC Power at boiler. Check breaker and wiring between breaker panel and boiler.
Display Panel Blank, Fan runningLoose 120VAC connection wiring between boiler J-Box and transformer Loose 24 Vac connection wiring between transformer and Sage2.1 Loose 5 Vdc connection wiring between display and Sage2.1
Boiler fires, but display panel is blankLoose 5 Vdc connection wiring between display and Sage2.1 Defective display
Boiler not responding to call for heat, Status screen reads “Central Heat T-Stat Off’Boiler is not seeing call for heat. Check thermostat or zone wiring for loose connection, miswiring, or defective thermostat/zone control.
Boiler not responding to a call for heat, “Standby” status is showing.Boiler is not firing. There is no call for heat or there is a call for heat and the temperature is greater than setpoint.
Boiler not responding to Domestic Hot Water Heat RequestBoiler is not sensing Domestic Hot Water Heat Request. Check wiring for loose connection, miswiring, or defective indirect water heater aquastat.
Boiler Running but System or Boiler Circulator is not runningCheck wiring for loose connection, miswiring. When there is a Domestic Hot Water Heat Request the System or Boiler pumps will be forced “off’ when there “Run Pump for” parameter is set to “Central heat, off DHW demand” or “Central Heat, Optional Priority”. This has been set to allow all of the heat to be provided for fast indirect water heater recovery. After one hour of “priority protection” or the end of the Domestic Hot Water Heat Request the system and boiler pumps will be free to run.

LOCKOUT NUMBERCONDITIONPOSSIBLE CAUSE
Anti Short CydeMinimum time between starts has not been reached. Normal delay used to avoid excessive cycles.
Boiler Safety Limit OpenBoiler Safety Limit wired to terminals J6-1.2 or 3 OPEN:• Loose wiring to limit device.
• Condensate Trap Float Switch contacts open.• Auto Reset Supply high limit sensor detected temperatures in excess of 200°F.
• Air Pressure Switch contacts open.• Defective Auto Reset Supply High Limit Switch.
• Auto Reset High Limit contact open.• Plugged Condensate Trap - also check to ensure boier is level.
• Air Pressure Switch contacts open - check for blocked vent.
• See possible causes for 'Hard Lockout 4’.
NOTE Block Vent Special Note Before a call for heat the air pressure switch is closed. When there is a call for heat with a blocked vent the air pressure switch will open (due to excessive pressure of the fan against a blocked flue pipe) after the fan starts. The control stops the start sequence and stops the fan. After the fan stops the pressure switch re-closes and the cyde continues. The displays shows the cause of trip for only the time the pressure switch is open.
Boiler Safety Limit Open.Boiler Safety Limit, or External Limit wired to termi- nals J5-1 OPEN:See possible causes for 'Hard Lockout 4’.
(ILK Off)• Jumper for External Limit wired to terminals 11 and 12 or device connected to it open.Loose wiring to limit device.
• Jumper for Low Water Cutoff (LWCO)External Limit defective or jumper not installed.
Switch or device connected to it open.Low Gas Pressure Switch contacts open (if installed). LWCO switch not installed and jumper missing.
• Jumper for Low Gas Pressure Switch or device connected to it open.If yellow light on LWCO is on. system is low on water.
If neither yellow or green light is on. check LWCO harness.
Return sensor faultShorted or open return temperature sensor.Shorted or mis-wired return sensor wiring. Defective return sensor.
Supply sensor faultShorted or open supply temperature sensor.Shorted or mis-wired supply sensor wiring. Defective supply sensor.
DHW sensor faultShorted or open Domestic Hot Water (DHW) temperature sensor.Shorted or mis-wired DHW sensor wiring. Defective DHW sensor.
Stack sensor faultShorted or open flue gas (stack) temperature sensor.Shorted or mis-wired stack sensor wiring. Defective stack sensor.
Ignition faiureFlame failure after 5 tries to restart.No gas pressure.
Gas pressure under minimum value shown on rating plate.
Gas line not completely purged of air.
Defective Electrode.
Loose burner ground connection.
Defective Ignition Cable.
Defective gas valve (check for 24 Vac at harness during trial for ignition before replacing valve).
Air-fuel mixture out of adjustment - consult factory.
Flame rod shorted to groundFlame rod shorted to groundShorted or mis-wired flame rode wiring. Defective flame rod.
Delta T inlet/outlet highTemperature rise between supply and return is too high.Inadequate boiler water flow. Verify that pump is operating and that pump and piping are sized per Section VI of this manual.
Return temp higher than supplySage2.1 is reading a return sensor temperature higher than the supply sensor temperature. Condition must be present for at least 75 seconds for this error code to appear.Flow through boiler reversed. Verify correct piping and pump orientation.
No boiler water flow. Verify that system is purged of air and that appropriate valves are open.
Sensor wiring reversed.
Supply or return sensor defective.
Supply temp has risen too quicklySupply water temperature has risen too quickly.See possible causes for 'Hard Lockout 4’.
Inadequate boiler water flow.
Verify that pump is operating and that pump and piping are sized per Section VI of this manual.
Fan speed not provedNormal waiting for fan speed to match purge and kght-off setpoinL
Supply high limitSage 2.1 supply sensor detected temperatures in excess of 210°F.• Heating load at time of enor was far below the minimum firing rate of the boiler.
• Defective system pump or no flow in pnmary loop.
• Defective boiler pump or no flow in boiler loop.
• Control system miswired so that the boiler operation is permitted when no zones are calling.
DHW high limitSage2.1 DHW sensor detected temperatures in excess of Setpoint.• DHW load at time of error was far below the minimum firing rate of the boiler.
• Control system miswired so that boiler operation is permitted when no DHW are calling.
Stack High limitSage2.1 Flue gas (Stack) sensor detected temperatures in excess of 204°F.• Heat exchanger needs to be cleaned.
• Boiler over-fired.
• Air-fuel mixture out of adjustment - consult factory.
Flame detected out of sequenceA flame signal was present when there should be no flame.• Defective gas valve - make sure inlet pressure is below maximum on rating plate before replacing valve.
