water level in fire tube boiler

Lay-up of Heating Boilers

Fill the boiler to its normal operating level with water hotter than 180°F. This temperature helps drive off dissolved gases. If hot water is not available, heat the water using the boilers burner after the water level reaches the lowest permissible level as marked on the boiler. Vent the air and gases as needed.
