Includes Plastic Float (also sold separately).
This product shows the water level in Models HE-1100, HE-2100, GX10, GX15, and GX30. This CANNOT be used for GH model furnaces. For GH furnaces, you can check your water level on your sight tube.
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.
