Required Clearances in front of VAV control boxes, fan powered boxes?

[John_187]

Hello,

I just want to confirm the required clearances in front of fan powered boxes and VAVs. The fan powered boxes are 277 V with electric heat. The VAVs however, do not have electric heat, and they are low voltage 24 V.

I had thought 3 feet for the fan powered boxes with electric heat, and 2 ft for the VAVs.

Can somebody please advise if you have experience with this?

Thanks for the help.
