Are you sick and tired of having drafts come down your chimney and waste your money on heating?

Are you prepared to switch to a more effective heating system?

No need to go any further—converting your vented fireplace to a ventless one is the answer you’ve been looking for!

It’s crucial to highlight before we get started that this process should be carried out by a professional because there are safety issues and construction codes to take into account. It’s also important to check with your local authorities to see if such conversion is legal and allowed in your area as many states and municipalities have restrictions that prohibit or limit the usage of ventless fireplaces.

Step by Step Process to Convert a Vented Fireplace to a Ventless one 

Here are the general steps you need to follow, to transform your fireplace.

Step 1: Seal off the chimney or vent to prevent drafts and leaks. This step is crucial in ensuring the proper operation of your new ventless fireplace.

 

Step 2: Install a new burner, logs, and other components that are specifically designed for use in ventless fireplaces. These components are specially designed to operate with the sealed chimney or vent and will ensure the safety and efficiency of your new ventless fireplace.

 

Step 3: Have the new burner and other components inspected and certified for use in a ventless fireplace by a professional. This step is vital in ensuring that your new ventless fireplace is safe and compliant with local regulations.

 

Step 4: Install an oxygen detection safety system to prevent the fireplace from consuming too much oxygen in the room. This system will automatically shut off the fireplace if the oxygen level in the room drops too low.

 

Step 5: Install a gas line and connect it to the new burner. This step will ensure that your new ventless fireplace has a reliable source of fuel.

 

Step 6: Test the new ventless fireplace to ensure that it is working properly and safely. This step is a final check to ensure that everything is in good working order before you sit back and enjoy your new ventless fireplace.

 

Now that you’ve completed the conversion, you’ll be able to sit back, relax and enjoy the warmth of your new ventless fireplace without any drafts or leaks. So go ahead, put on a cozy sweater and enjoy a hot cocoa by the fire.

Conclusion

In conclusion converting a vented fireplace to a ventless fireplace requires a significant amount of work and should be done by a professional. Additionally, many states and municipalities have building codes and regulations that prohibit or limit the use of ventless fireplaces, so it’s important to check with your local authorities to see if such conversion is legal and permissible in your area before you begin the process. And remember, always be safe, have fun, and enjoy the warmth of your new ventless fireplace!
