How to Attach a Vent Pipe to an Oil Furnace
When it comes to your oil furnace, it is absolutely crucial for it to have a vent pipe. If there is no vent pipe, all of the smoke and other noxious gases will accumulate inside your house. The vent pipe allows all gases to leave your house. It serves as an exit way. Whenever you have a new furnace, it is always important that you install a new vent pipe before operating the furnace. Ideally, you need an existing fireplace chimney in order for you to install your vent pipe. Make sure that the vent pipe for your oil furnace does not come in contact with your stove vent pipe because methane gas is flammable.
Step 1 – Do the Preparations
The presence of a chimney flue is important in this installation since you will be attaching the new vent pipe through the flue. In order for you to find out where the flue is, all you have to do is to take a look at your chimney. Through your inspection you will be able to discover a piece of flue. Measure the distance from your oil furnace to the existing chimney flue. You will notice that your chimney flue is covered with a round piece of metal. Simply unscrew the cover and measure the diameter of the flue pipe.
Step 2 - Purchase the Pipes
With the measurements that you have in hand, you can now go to the hardware store and purchase the right pipes. Also purchase elbows for corners. Make sure that you get pipes that have the same diameter as your flue pipe.
Step 3 - Install the Pipe
Install an elbow pipe to your old chimney flue. In order for you to do this, you need to use screws and a drill or hi-temp silicon. If you want to be really thorough, then you can employ the two procedures. In you are using hi-temp silicon to attach your elbow pipe, you will have to wait for at least an hour before you can proceed.
Step 4 – Assemble the Pipes
While you are waiting for the glue to dry, start assembling the other pipes. Simply attach an elbow pipe to the pre-cut pipes with the use of either screws and glue or both. Once you are done with that assembly, you will have an L-shaped pipe.
Step 5 - Attach the Pipes
When the elbow pipe attached to the flue has hardened and the pipe assembly connections have dried, you may then attach the pipes together. You will have to attach the L-shaped pipe assembly to your chimney flue and your oil furnace. For you to secure the pipes together you will have to use either screws or silicon but it is best if you utilize both procedures. You need to wait for at least half a day before you can use your newly attached oil furnace vent pipe. The next step that you might want to take is to insulate your vent pipes.
