[Bill-N-Donna]

We have the Splendide combo in ours and when we installed it the Monty it was already set up for the hook ups. There was a sticker on the wall in ours indicating accordingly. We did check with a factory rep before making the hole but when I cut it I cautiously cut a hole from the inside before I cut through the outside wall. I figured at least if something was in the way I could fix a patch from the inside easier than I could repair the outside wall. I made the hole directly where the vent was on the combo unit for a straight shot to the outside.
