Boiler in Finished Basement II (*quiz)

[energy star]

Fraid not, no nailing it there. He ended up with a 4'' round duct. Took room volume into account. You asked for duct size for needed for "outside " air. MTL had it first, but kinda oversized it, when he went with 8".

You asked for duct size for needed for "outside " air.

Fraid not, never did.

Thank you to all who participated and I hope that we all learned something from this.

The homeowner has decided to bring in fresh air from the outside for combustion air.

What size opening to the exterior is needed to accomplish this?

My mistake.

[Jeff Remas]

You know what. This has been a pretty good thread so I would like to continue it.

If the scenario was exactly the same EXCEPT instead of a gas fired boiler, it was a oil fired boiler. Would the answer be the same?

If not, why?

Come on energy star, go ahead and let us know the answer. The IRC Jersey version for the mechanical section is the same as the regular IRC for this question so it won't affect your answer. Learn me somthing.

Oh, I'm sorry dude. Not from me. You need that oil combustion air, thats hard to find in these parts.

[Jeff Remas]

The NJ HVAC licensing law does not differentiate between fuel oil and fuel gas contractors. My aunt in Navesink, NJ has a oil fired boiler.
