What is A Gas Fireplace Insert?

A gas fireplace insert is an efficient, clean-burning source of heat that fits into the existing structure of your home’s fireplace. They are designed to burn natural gas or propane and often come with realistic-looking logs, embers, and sometimes flames that closely mimic a traditional fire.

How To Install A Gas Fireplace Insert

Flipping a switch and having gorgeous flames provide heat and ambiance on a cold day is the perfect living you may have been searching for. But how do you install a gas fireplace insert, especially if you want to do it yourself?
This step-by-step guide will help you to install the fireplace insert quickly and efficiently. It can also prove helpful if you’re looking to replace a gas fireplace insert.

Assess Your Existing Fireplace and Chimney

Before installing a gas fireplace insert, it’s important to evaluate your existing setup to ensure compatibility and safety:
Measure the height, width, and depth of your existing fireplace. This will help you choose an insert that fits perfectly.
Inspect your chimney for any blockages, damages, or leaks. Since the gas insert will utilize the chimney for venting, it must be in good condition. We recommend working with an expert for a professional inspection.
Determine if you already have gas lines installed or if new lines will need to be run. This step might also require a professional assessment.

Choosing Your Gas Fireplace Insert

Selecting the right insert involves several considerations:
Based on your fireplace measurements, select an insert that fits snugly and meets the safe distance required away from combustibles.
Consider the size of the area you want to heat and choose an insert with an appropriate BTU (British Thermal Units) output.
Choose a design that matches your home decor. Additionally, look for features like adjustable flame control, remote control operation, and thermostat integration.

Necessary Tools and Materials

Prepare the following tools and materials for the installation:

Preparing for Installation

Check with your local building authority to obtain necessary permits and ensure your installation complies with local building codes, especially concerning gas appliances and venting requirements.
Clean the existing fireplace thoroughly, removing any debris, soot, or ashes.
Ensure the chimney is clean and clear of obstructions. You may need to hire a professional to clean and inspect it.

Installation

Install a venting kit that is compatible with your gas insert. Run the vent from the insert up through the existing chimney. Use a high-temperature sealant to secure all connections.
Carefully slide the gas insert into the cleaned fireplace opening, making sure it is level. Secure the insert into place based on the manufacturer’s instructions, typically involving screws or brackets.
Connect the gas supply line to the insert using a flexible hose. Ensure all connections are tight and leak-free using the appropriate fittings and a pipe wrench. If your insert has electrical components like a fan or remote control, connect them to a nearby power source as per the manufacturer’s instructions.
Perform a leak test on all gas connections using a soapy water solution. Watch for bubbles that indicate a leak. Ignite the insert and observe the flame. Adjustments might be necessary to ensure the flame burns cleanly and efficiently. We highly recommend working with a safety inspector to guarantee your safety.

Final Touches

Attach any surround or trim pieces that come with the insert to give it a finished look that integrates with your existing décor.
Use high-temperature caulking around the edges of the insert to improve efficiency and prevent drafts.
