Step By Step Installation Procedure Of Electric Fireplace Insert

Step 1. Take Necessary Measurements

So, check and double-check measurements before placing an order on Amazon or eBay.

How and what to measure?

First, take a measurement tape.  And then measure the length, width, depth, and height properly of your existing fireplace or fire pit.

So, this measurement will help you to narrow down your electric fireplace insert choice as you may find many electric fireplaces which will not fulfill your requirement. You can choose a fireplace that is smaller than your existing fireplace measurement. But, make sure that your chosen one looks good on it.

You can also get one that is slightly bigger than your fireplace. But, you need to do the necessary initiations before installing it.

Once you have finished choosing your desire electric fireplace, your job is not done yet. It’s time to go down to the next step.

Step 2. Removing Unnecessary Parts and Cleaning Fireplace

Electric fireplace Chimney Cleaning

Your old fireplace may have doors, grates, or screens. You may not need them if you use an electric fireplace. You know what you have to do next. You just need to remove them from your fireplace.

You may also find a blower fan in the old fireplace. Go ahead and remove it as it is useless for the electric fireplace insert. Make sure that there is adequate room in your existing fireplace to place an electric fireplace insert.   

When you finished removing useless parts of your old fireplace, next you have to clean your fireplace. You will find build-up like dust and debris stuck on the wall. What you need to do is- take a hard brush and clean wherever you see dirt and dust.

Step 3. Cover Your Chimney From Rain and Snow.

Put a cover plate on your chimney. This will prevent water from coming in. A cover plate is highly important before installation as it prevents water from coming in – in case your chimney doesn’t have a rain cap.

It’s very difficult to put a rain cap on your chimney. So, we advise you to hire a chimney expert for this.

Step 4. Seal the Damper

The damper is a very crucial part if you have a gas or wood fireplace in your home fireplace.

It is used to link the fireplace with your chimney. In the case of an electric fireplace, you don’t need a chimney, as well as a damper.

So, close and seal the damper of your masonry fireplace. This will prevent drafts and loss of heat.

You may follow several techniques to seal the damper. But, we suggest you use an inflatable pillow or plywood pipe insulation for sealing.

Step 5. Power Outlet Setup

The next thing you’ll need to do is to install a power outlet inside the opening. NOTE that all-electric insert plugs into standard household power outlets. It’s best to install an outlet outside of your existing fireplace.

You may not handle this part if don’t have knowledge about electrical wiring. So, hire a certified HVAC expert for this and make sure you merely install the power outlet low and near the fireplace.

Step 6. Install The Electric Fireplace

All the hard work is done, now it’s time for real action.

Put the electric fireplace unit into your fireplace.

Step 7. Securing Your Fireplace Unit

Next, slide the firebox inside of this opening, center it, and levels it out. Some inserts come inclusive of tie-down brackets that a user will need to attach to the fireplace floor and back of the insert on both sides to secure it and ensure it doesn’t tip.

Step 8. Install the Trim

This is your final step. Now that insert is safely secured in place, attach a trip or frame that will cover up gaps between the insert and walls of your heater’s opening. Some models come inclusive of glass frames while others come with metal trims.

And there you have it; a complete electric fireplace ready for action.
