Attic Location
Gotta question for yaz!
Relocating a new FAU to the attic. Plenty of combustable inlet and all looks good! Was wondering about the insulation. No R-30 to speak of however the entire (single story-residential) attic has blown insulation. Is there a code set requirement for the FAU's height or distance away from, above the blown? If so, can't we just install more ply atop the CJ's? Thx |

Re: Attic Location

I can tell you what I normally see:

Re: Attic Location
You don't mention whether this FAU will have A/C along with the furnace, but if it does then you'll need (at least in Calif.) to install a secondary drain pan under the coil. If not then just check the clearances to combustible surfaces in the specs. Most units require some clearance away from wood surfaces. I've seen some installs where they place sheet metal on the blocking where it sets to handle this.
