Louver doors for M3Rl-80
Posted: Sat Jul 11, 2009 4:11 pm
Would a 1/2 louver door be enough for return air when the furnace is in a closet about double it's size?

The furnace will come with the needed return air grille. IF the furnace is correct size for home, then the return air will be correct also.
If closet has a door, it must have adequate return air grille for amount of airflow eaqual to furnace return air grille.
Thanks,
