Hey Ed, our code requires a supply grille in every room even if Manual J® calls for zero CFM. Any advice?
In this edition of “Hey Ed,” Ed discusses supply grill regulations.
Hey Ed, our code requires a supply grille in every room, even if Manual J® calls for zero CFM. Any advice? That is a question that has come up quite a bit as of late. And when I look in any of our manuals, I cannot find any specific reference to what is or isn’t required. What we have done in the new manual D that’s coming out is we have listed that if there is a 300 BTU requirement or less, no supply outlet is required. And that’s the way I see it.
