Where is the drain hose location on a Rheem gas furnace?

Answer by  kipcat (1964)

If you are looking for the condensate drain from the secondary heat exchanger, it is off to the left coming from the bottom of the flue pipe. The heat exchanger generally has two pipes, one is the overflow, the other is the drain. They may be tee-d together inside the furnace door.

You will find the drain hose on a Rheem gas furnace tucked away behind the boiler. First turn the furnace off, then let it cool down. Next, look behind the boiler and should should see the little pencil sized drain.

It is not connected directly to the furnace itself. It is on the coil portion of the unit, which is sold seperately but as a whole. Once you obtain a coil to fit the furnace you should have no problem finding the drain. It should be drained to the outside of the home or to the main drain.
