Removing a gas fireplace is not DIY-friendly, but it needs a certified professional to handle gas appliances. The steps involved in this project will depend on the type of fireplace you are dealing with and its size. But, for all kinds, the professional will first disconnect the gas supply, remove the trim, the surround, then disconnect the fireplace from the gas supply pipe.
Before removing a gas fireplace, it is necessary to have professionals disconnect electricity and gas supplies. It is a legal requirement that only a licensed expert can work on gas appliances in many locations. It can be a hazard to attempt to remove this fixture with the gas supply still on.
This article looks at the types of gas fireplaces and how to remove each of them. We also highlight the cost of removing a gas fireplace and the benefits of having one. Read on!
What Are The Different Types Of Fireplaces Available?
The kind of fireplace you are working on may influence the steps you undertake and the tasks involved when removing it. Here are the most common types;
B-vent (Also Known As Natural Vent) Gas Fireplaces
Natural vent gas fireplaces typically occur as inserts in existing masonry fireplaces. These fixtures utilize the chimney for venting. You may not need to disconnect any vent during the process of removing the fireplace.
Ventless Gas Fireplaces
This type of fireplaces vent from within, and removing them is easier compared to other models. But, they are rare than direct vent models.
Direct Vent Fireplaces
Unlike the natural gas fireplaces with an open front, the direct vent fireplaces have a glass front. These fireplaces vent waste and clean air externally, and one needs to detach the vents before removing the fireplace. If there is an electricity supply to the fireplace, you will need to remove it also.
What Are The Main Steps In Removing A Gas Fireplace?
Removing the gas fireplace needs to follow specific steps, including;
Disconnecting The Gas Supply
The first step in removing a gas fireplace is to isolate the gas supply. This process involves;
1. Turning off the main supply of the gas to your house
2. Shutting off the gas supply to the fireplace
For you to turn off the gas supply, look for a shut-off valve and turn it perpendicular to the pipe. Doing this will help disconnect the supply to the fireplace. Make sure that the professional working on the task confirms that no gas leaks from the insert. The shut-off valve may be located at the side of the chimney breast or within the fireplace.
Disconnecting The Trim
Most fireplace models (especially the inserts) have a trim at the edge of the frame. The trim may sometimes conceal the gap between the surrounding walls and the fireplace. It is, therefore, necessary to remove it before removing the fireplace. Removing this part helps the unit to be seen well.
Taking Out The Surround
Some gas fireplaces are supported inside the masonry fireplace by a surround that also needs to be removed. Removing this surround can allow you to access any items or vents behind it, making the task easier. Some surrounds could be joined to the chimney breast using screws that need to be unscrewed.
After removing the surround, you can then remove the backing plate too.
Detaching The Fireplace From The Gas Pipe
A gas fireplace is primarily linked to the supply pipe, which needs to be removed first. Since different models have varying locations for the gas pipe, be sure to check where yours is located and disconnect it.
Removing Vent Items
For direct vent gas fireplaces (those that vent fresh and waste air externally), you need to check how to separate the vent apparatus from the fireplace. Ventless and natural B-vent gas fireplaces have no venting items to consider. For example, these fireplaces have no ventilation pipes, but a vent hood at the top helps natural gas to rise up the chimney and remove the waste air from your house.
Removal Of Electric Connections
Most modern gas fireplaces use electronic ignition systems. For the system to operate, it needs a connection to the mains electricity for the house. So, before removing the gas fireplace, make sure that you remove these connections.
Getting Rid Of Cable Fixings
Some gas inserts have cable fixings at the back that attach them to the masonry fireplace walls. The cable fixings also help the gas insert be stable and not move while connected to the gas line. If these cable fixings are present, be sure to detach them before removing the gas fireplace.
Disconnecting The Gas Fireplace
After removing all the connections that hold the gas fireplace in position, the final step is to remove the gas fireplace itself. The gas fireplace usually comes out as a single unit. However, for natural vent models with an open front, you need to take out any object that may be loose first.
Capping The Gas Line
When all the above steps are successful, the professional working on the project will have to seal off the gas pipe left behind. Ensure that capping is done correctly whether a new gas fireplace will be installed or not.
How Much Does It Cost To Remove A Gas Fireplace?
Removing a gas fireplace can cost between $250 and $1000. This cost includes removing the simple direct vent models, sealing of electric and gas pipes. Removing bespoke installations with larger flue systems could cost more than the price above. Such facilities will also involve removing and repairing the surrounding wall.
If you remove both the gas fireplace and chimney, you could pay anywhere between $3,000 and $6,000. This amount will cater to the demolition of the breast and stack, repairing the walls, roof, and floor, and installing structural support.
The following table shows the estimated cost of the fireplace and chimney removal.

$500 – $2,500
$2,000 – $4,000
Repairing the floor, walls, sides, and roof
