Installing a gas fireplace insert may seem complicated, but with the right professional help, it can be a smooth process.

How to Install Gas Fireplace Insert Easily?

There is nothing big in installing a gas fireplace insert, you just put money in a good fireplace insert, gas fire and good professionals, that’s it!

Step 1: Select the Right Gas Fireplace Insert

The first step is choosing the right gas fireplace insert for your existing fireplace opening. Carefully measure the dimensions of the firebox to ensure you select an appropriately sized unit. Opt for the largest insert that will fit to minimise excess space around the new appliance.

You’ll also want to decide on design elements like log styles, flame effects, controls, lighting, and more. I would recommend looking on the Internet for a selection of modern gas fires online.

Step 2: Hire a Professional for Installation

Gas fireplace installation is not a DIY project. Proper installation requires connecting both gas and electricity, as well as critical venting work. Attempting to install a gas insert yourself risks fire hazards, gas leaks, and other dangerous situations.

Instead, hire a qualified professional installer. They have the expertise to safely run gas and electricity, obtain permits, and perform all installation steps to code. Your local dealer likely has a network of trusted installers they work with regularly.

Step 3: What to Expect During Installation

Though timelines vary, installing a gas fireplace insert typically takes 3-10 days from start to finish. Here’s an overview of the process:

Preparing the Firebox

The first step in installing a gas fireplace insert is preparing the firebox. This involves removing old components like screens, doors, and grates. The firebox and chimney are then thoroughly cleaned out and any existing pieces are hauled away.

Electrical and Gas Work

After preparing the firebox, the next step is electrical and gas work. An electrician runs wiring from an outlet source to the firebox and a gas fitter runs a gas line from the home source to the firebox. A pressure test is performed to check for leaks.


The venting process comes next. A flexible liner is dropped down the chimney and capped. Insulation is added between the liner and the flu.

Inserting the Gas Fireplace

The gas fireplace insert itself is then installed. The appliance is carefully levelled, aligned, and secured into the firebox.


Once the gas fireplace insert has been properly positioned and secured within the firebox, the installation process moves to the inspection phase. Required inspections will be conducted by local building code officials and inspectors to ensure the insert has been properly installed and meets all safety and code regulations.

The inspection process helps validate that the venting, gas lines, electrical wiring, and fireplace surround were all completed to code.

How to Maintain Your Gas Fireplace?

Once installation is complete, very little maintenance is required to keep your gas fireplace running smoothly for years to come. Follow these tips:

  1. Have a professional service the unit annually. This includes inspecting connections, testing the pilot light, and cleaning.
  2. Clean the glass as needed using a fireplace glass cleaner.
  3. Replace batteries in remote controls as needed.
  4. Keep the area around the fireplace vent clear of debris and snow.
  5. If you notice any issues like unpleasant smells or abnormal noises, discontinue use and contact a professional service technician immediately.

Final Words

Installing a gas fireplace insert takes careful planning, hiring qualified professionals, and following building codes. But the result is well worth the effort. With your gorgeous new gas fireplace providing ambiance and warmth with the flip of a switch, you’ll be thankful you invested in this renovation. Just be sure to follow the maintenance tips provided to keep your fireplace running safely for years of cosy enjoyment. With the right prep and process, a fireplace makeover can take your home to the next level.
