Optimax 2007 150 hot water out upper exhaust?

[mcgyver]

Just changed my waterpump, I can't remember if this is normal. I have a faucet size stream of hot water coming out the upper exhaust port (square one below the telltale exit). It's pretty hot and don't know if I screwed something up when I reinstalled the lower unit. I have a stream coming out the telltale.
