Measuring a Fireplace

Electric Fireplace

Measuring a fireplace is more than measuring the width and height of the fireplace opening. It is worth noting that most fireplaces are designed with angled walls. This means that you will find some parts to be smaller if you measured the face of the fireplace.

To measure the electric fireplace, you are required to record the height, width, and depth of your firebox. Keep in mind that the firebox is the typical opening in your fireplace where you start a fire. The fireplace insert should properly fit on the firebox.

Therefore, you must take accurate measurements. That being said, ensure that you have crucial tools and head over. At this point, you will be using a notebook to record the measurements.

Step 1: Measure the Height of the Fireplace

Measure the Height

At this point, you must take different measurements. Record the height of your firebox. This should be done at the opening. Measure the height at the firebox back. Finally, make sure to measure the lintel.

Usually, the lintel is found on the horizontal section just above the firebox opening. The main essence of the lintel is to give your fireplace extra support.

The lintel is not visible at times because it is embedded on the fireplace brickwork. In case you have difficulties measuring the lintel, you can go ahead and add 1/8 inches to your measurements.

This is crucial in allowing clearance. Record the opening at the lowest and highest levels if your fireplace has an arch design.

A quality measuring tape makes the whole process easy. It is good to know that the height or depth of your fireplace will remain the same for a square insert.

However, you might notice a slight difference in an arched fireplace. With that in mind, check well to avoid inaccuracy.

Step 2: Check the Width Dimensions

Width Dimensions

When measuring the width, you are supposed to take at least four measurements. However, this mainly depends on the geometry and design of your firebox. The fireplace should be measured at the front opening.

Remember to measure both the top and bottom of the opening. Record accurate measurements across the back wall of your firebox. Add measurements if you have an angled firebox.

All the above measurements will help you verify whether your firebox has a true square. A square firebox should have the same width on the top section and bottom.

Angled fireboxes on the other hand should have different numbers. Don’t forget to record all your measurements immediately.

Step 3: Measure the Depth

It is the last measurement you must take if you want to know how deep your firebox is. Take measurements from the front section of the rear wall.

You will have an easy time recording accurate measurements if you consider taking the measurements from the center of the firebox.

Using a measuring tape, take the measurements as advised above. It is advisable to take the smallest measurements to prevent any problems in the future. You can check the center at different places if you want to get accurate results.

Check the user manual of the measurement guide if you will be purchasing from an online store. This will guarantee you the best results.

Step 4: Check the Location of Outlet

Locate the outlet now that you have analyzed the product dimensions and opening area. The best thing about an electric fireplace insert is that it can be installed anywhere in your home. However, it is still important to check the location of the outlet.

Most of the fireplaces being sold in the market are designed with six-feet cord. This means that the user must have a preinstalled extension cord especially if the outlet is far. The extension cord is essential in giving a dirty look.

Hardwiring is a bit different but it does not have any impact on the outlet. Always choose the best and ideal location for your unit. From there, you can start measuring the outlet area from your desired location.

While this step is not a must, it is considered a crucial step for accurate results.

Step 5: Accuracy is Key

Accuracy is Key

To guarantee accurate measurements, it would be better if you recorded at least five measurements. The measurements can be from the rear width, rear height and opening width.

For a fireplace designed with like an arch, you can record different measurements. Use the smallest measurement every time you are looking for an insert.

In case you did not take your measurement correctly, you must force the insert in your fireplace. Alternatively, you can consider modifying the fireplace opening.
