how do I clean the A coil?
Posted: Sat Jun 26, 2010 6:09 pm
I have a propane Duo Therm model #717060-001 furnance with an A coil in the bottom. I want to clean the A coil. The A coil is located behind a metal plate which is secured by screws. Through the plate is a hole with two copper pipes and one rubber hose. The copper pipes are threaded. The pipes and the hose must be disconnected to remove the A coil and this is a pretty straight-foward proceedure? Is this correct?
