Goodman heat pumps under a deck
I have 2 goodman heat pumps (model GSH130301A).
I want to build a deck, which will be approx 18" over the top of the machines.
The Goodman installation instructions say not to have any obstructions less than 60 inches above.
If I place grates in the deck to let the exhaust pass, should there be any problem? (the grates will be 32" X 32" with the deck frame headed off - no 2x8s over the heat pumps)
What do you think a Goodman engineer would say ?
(the building inspector needs a signoff from the mfg)
