How to Clean a Mobile Home Furnace Firebox

Many mobile homes have a furnace, regardless if the mobile home is stationary or if you travel with it. Like any home equipped with a furnace, the furnace will need proper cleaning a few times a year. A furnace has a firebox, also known as a burner box, and ash or dust buildup may accumulate over time inside the firebox, which may cause the flame inside the firebox to burn out. Keeping the firebox free of buildup will help your furnace to function properly and safely.

Instructions

1. Turn the power supply off for the furnace at your electrical breaker box. If your furnace uses gas in addition to electric, turn off the main gas supply also.

2. Unscrew the screws that hold the cover in place over the access door to the firebox, or burner box, with a Phillips head screwdriver.

3. Vacuum the interior of the firebox, using a hose attachment on your vacuum.

4. Wipe the interior walls of the firebox with a dry, lint-free cloth. Do not moisten the cloth.

5. Replace the access door and screw it back into place.

6. Turn the power and gas supply back on to your furnace.

Tips & Warnings

• If you do not have a vacuum to use, use a small hand broom and dustpan to sweep out the interior.
