The drain valve is near the rear of the burner and can be reached without removing the burner. It will the tight though as it is behind the burner.
You can use engine coolant, the same as in generator and/or engine. Newer heaters with an electronic control board require GRAS (Generall Recognized As Safe) boiler antifreeze or coolant.
