This product shows the water level in Models HE-1100, HE-2100, GX10, GX15, and GX30.
Instructions for use:
Insert your new Water Level Indicator (WLI) into the top front vent tube of your Outdoor Boiler with the sticker/indicator facing forward. Make sure the float body is perfectly horizontal before inserting. Use caution if you remove the WLI so you don’t pull the float off, as it is a snug fit. Add water when indicator reaches “ADD” or just above. Add water using only the OutdoorBoiler.com “In-House Fill Kit” installed indoors; using buckets or hose is not recommended. When adding water, add slowly and shut off water immediately when water overflows this vent tube onto furnace roof.

One of the most important steps in prolonging the life of your outdoor boiler is to ensure that the water in your boiler is not corroding the steel. Water starts to eat holes in steel immediately upon contact (through rust corrosion) unless properly treated. We test your outdoor boiler water for free!
