Got an 80s vintage GCS10-653 on a roof. These are side discharge gas packs but the air then is transitioned into the roof. Appears to be sitting on a factory curb. I'm nervous about adapter curbs, wanna be sure the supplier is getting the right one. So if anyone is familiar with that unit or knows curbs & adapters well, please pipe up.
The attachments are showing curb drawings. One came from the new unit vendor, Bryant. The modern drawing of what they think the Lennox curb is came from another vendor but for the same UT/ICP unit. The adapter drawing came from the Bryant supplier. The old drawing came from Davenet, original to the old RTU. Actually that pdf didn't work so I attached the whole GCS manual. The curb info is about 2/3 way back.
Opinions on whether that adapter curb is ok!
