Resolved Question:

Hi, I have a American Standard Arcoliner Furnace. It currently has a
Tankless Heater Installed in the Furnace (Bolted attachment). It works but I will be adding a seperate Hot Water Heater (Gas). Yes, someday I will be replacing the Furnace, Electrically I can disconnect the Tankless Heater, Can I still run the Furnace with it installed and no water? Should I cap its ends or leave them open? Thank You

Welcome to Just Answer,

You can leave the tankless coil in place just cut the water line and leave them open. Some water will boil out of the coil for awhile when the burner fires up but it will eventually dry out
