2006 bt 5270
Purchased a used 2006 bt 5270. I am trying to dewinterize the unit and have a couple of questions.
1. Where is the water heater bypass control?
2. The low point drains are under the sink with two of the plastic knobs locked in place by clips, you can turn them but they will not go up or down. They appear to be in the down mode. Any help will be appreciated.
