A Guide to Cleaning Your Heat Exchanger
You might have wondered about cleaning your heat exchanger, especially if you have an older draft hood furnace. The YouTube video “How To Clean a Heat Exchanger” shows how you can do everything at home and save yourself some trouble in the future. Let’s find out more!
Before you get started, check to see if your heat exchanger has a protective device for flame roll-up. The model shown in the video does, as it works by rolling up flames up to the front.
The device can help in case flames are out everywhere, but it’s not foolproof by any means. That’s why cleaning it is the best option.
First, you’ll need to take the top cover off. It comes with screws you can easily take off. There, you’ll find the draft hood. You’ll have to take that off too, by unscrewing the screws at the bottom and top of it. After taking it off, you’ll find your heat exchanger tubes and the baffles. The problem arises when dust accumulates near those baffles and clogs the system. You’ll have to take out the baffles and use a tree brush to remove all the debris as best you can.
