Diy Gas Furnace Replacement

The second major safety concern would be ventilation.

Diy gas furnace replacement.

In a hot air system a blower forces air through ducts that open into each room. Furnaces consist of two main operating systems. If you are replacing an existing furnace you just need to carefully extract the old furnace from the big metal boxes then seal the new unit to the same boxes. One for generating heat.

Remove the door on the front of the furnace cabinet to give you access to the blower it might be on a slide out drawer check the number stamped on the belt and get an exact replacement from a home center or heating supply outlet. First turn off all power to the unit and turn off the gas at the gas valve that serves the furnace. Most furnace units will already have a gas line run so making sure the connections are secure and there are no leaks will be one of the main safety concern. After all blowers are basically just large fans.

Vacuum everywhere you see dust. The main issue will be safety for not only installing a furnace but mainly when dealing with a gas line and exhaust of the furnace. The other for distributing it. Turn off the power switch again and shut off the gas by giving the valve one quarter turn.

Vacuum the furnace burners and the furnace base. To get at the back of the burners tape a 20 in. Drain line to your vacuum hose.
