: The answer to your question may vary depending on the type of boiler. A good rule of thumb for Scotch type boilers would be if the boiler cycles on/off more than 7 times an hour you want to keep it running on low fire. Keep in mind every time the boiler goes through a purge cycle you are losing a lot of heat up the stack.
All good suggestions, Have you checked to see if burner has been properly set so you are achieving the maximum turndown ratio? Going to manual would afford no benefit if your pressure controls are properly set, you should already be at low fire if you are approaching the off point.
