re: Water Heater Drain Code

There's no combustion source/risk of gas leaking in an electric heater, so it won't need ventilation. The drain pan would be the only thing that would tell you there's a leak of some sort in that event. It should still have somewhere to drain the heater for maintenance purposes, but that doesn't have to be hooked up. More than likely since you're in a second story condo, it wouldn't make sense to route plumbing to drain the heater out of the building, especially if there are a lot of units there.
