How to stop rapid cycling on PEERLESS Series 63 (Water Boilers)?
If your PEERLESS Boiler (water) is rapidly cycling, it could be due to a temperature control differential that is too narrow. Adjusting the control differential should resolve this issue.
What causes rapid cycling in PEERLESS Series 63 Boiler (Steam Boilers)?
If your PEERLESS Boiler (steam) is rapidly cycling, it could be due to air vents or traps not venting air, preventing steam from getting to radiation and pressurizing the air pocket; replace the vents or traps. The pressure differential on the pressure control might also be too close, so adjust the control differential. Additionally, nuisance outages of the water level control due to boiler water level bounce can cause rapid cycling; refer to the section on excessive water level bounce for solutions.
Why is gas spilling from draft hood relief opening on my PEERLESS Series 63 Boiler?
If gas is spilling from the draft hood relief opening of your PEERLESS Boiler, it's likely due to insufficient draft. This could be caused by a chimney that is too low or too small, in which case you should increase the height, replace the chimney, or add an induced draft fan. Another cause could be a blockage in the chimney or vent, which would require repair. A downdraft caused by the chimney's location relative to other buildings or roofs might also be the reason; installing a chimney cap could solve this. Negative pressure in the boiler room, due to an exhaust fan or duct system, or insufficient combustion air openings, could also be the cause, which you can fix by removing the exhaust fan or isolating it from the boiler room, or providing correctly sized combustion and ventilation air...
Why are the burners burning with yellow flame on my PEERLESS Series 63?
If the burners on your PEERLESS Boiler are burning with a yellow flame, several factors could be responsible. The air adjustment screws may be turned in too far, requiring adjustment outward. Low gas pressure in the manifold could also be the issue, necessitating adjustment of the main gas pressure regulator or a check of the line pressure. Partially closed burner ports due to rust, dirt, or lint could be another cause, which you can resolve by replacing the burners or cleaning the ports. Additionally, insufficient air for combustion may be the problem; check the size of combustion air openings to the room and correct as required, and check for negative pressure in the boiler room. Finally, an oversized burner orifice or high gas pressure in the manifold could be the cause, requiring insta...
