🔍 Key Concepts

• Boiler combustion air flow: role of uptake dampers vs air register doors • What happens to furnace pressure and flame stability if air flow on lit burners is restricted too much • Safety considerations for idle (non-burning) burners and their air registers

💭 Think About

• Ask yourself: Should the path for flue gases to leave the boiler ever be intentionally throttled while fires are lit, or should it remain as free as possible? • For burners that are actually firing, is better control of combustion done at the stack (uptake damper) or right at the burner (air register door)? • On burners that are not lit, would you want air flowing through them into the furnace, or should that path be shut off? Why?

✅ Before You Answer

• Be clear on the difference: uptake damper = gas exit path, air register = combustion air at each burner • Decide which component (uptake vs air register) should be locked open for safety when fires are lit • Confirm what is safest for idle burner air registers: allowing air flow or keeping them closed to prevent unwanted draft paths

Question 1 of 20

While fires are lit in a boiler, in terms of uptake dampers and air register doors, what conditions must be met?

All uptake dampers should be locked open, all air register doors on lit burners should be wide open or throttled, and all air register doors on idle burners should be closed.

All uptake dampers should be locked open, all air register doors on lit burners should be throttled according to the firing rate, and all air register doors on idle burners should be open.

All uptake dampers should be throttled according to the firing rate, all air register doors on lit burners should be wide open, and all air register doors on idle burners should be closed.

All uptake dampers should be throttled according to the firing rate, all air register doors on lit burners should be throttled according to the firing rate, and all air register doors on idle burners should be closed.
