Choosing the right gas fireplace for your home means understanding the options, the vent systems, installation implications, and the features that matter most. Smoky Mountain General Store offers a wide selection of gas fireplaces and accessories, and this guide outlines the main types of gas fireplaces, fireplace options, and the benefits of each so you can pick the right gas fireplace for your needs.
Types of Gas Fireplaces
There are three main types of gas fireplaces: direct vent gas fireplaces, B-Vent (natural-vent) gas fireplaces, and vent-free (ventless) gas fireplaces. Each type has different vent systems, efficiency ratings, and installation requirements.
Direct Vent Gas Fireplace
Direct vent or direct-vent gas fireplaces draw combustion air from outside and exhaust directly outside through a sealed pipe system. This makes direct vent gas fireplaces a popular choice for new gas fireplace installs and existing fireplace openings that need a clean, efficient option.
Direct vent gas fireplaces and direct vent gas stoves offer modern gas efficiency while maintaining indoor air quality.

B-Vent (Natural Vent) Fireplaces
B-Vent fireplaces use natural draft to vent combustion gases through a vertical chimney or vent pipe. Also called natural-vent fireplaces, these are commonly used when connecting to an existing masonry fireplace chimney.
B-vent gas fireplaces can be a good fit for homes with existing wood-burning fireplace chimneys, but they tend to be less efficient than direct-vent models.
Vent-Free (Ventless) Fireplaces
Ventless gas fireplaces, also called vent-free fireplaces or vent-free gas systems, do not use an external vent. They burn gas very cleanly and provide high heat output because all heat stays in the room. However, some regions restrict vent-free fireplaces due to indoor air quality concerns, so check local codes before choosing a ventless gas fireplace.
Other Gas Fireplace Options
Beyond the vent type, there are several formats and styles to consider:
-
Built-in Gas Fireplaces – These are designed to be installed into a wall or existing fireplace opening for a seamless look. Smoky Mountain General Store carries built-in gas fireplaces in contemporary gas and traditional styles.
-
Gas Fireplace Inserts – A gas fireplace insert is designed to fit into an existing masonry fireplace. Installing a gas insert is a common way to convert an existing wood-burning fireplace into an efficient gas fireplace.

-
Gas Log Sets – Gas log sets can be used in existing fireplaces and are available for vented or vent-free installations. Gas logs mimic the look of traditional wood logs and can be used with a gas fireplace insert or directly in the firebox.
-
Gas Stoves – Freestanding gas stove units offer a classic look and are available in direct vent and vented configurations. Gas stoves are often used to heat larger spaces.
-
Outdoor Gas Fireplaces – Designed for outdoor spaces, outdoor gas fireplaces and fire tables provide warmth and ambiance on patios and decks. They require specific venting and materials suited for outdoor use.
-
Linear Gas Fireplaces – Contemporary, wide-format fireplaces that create a modern focal point. Linear gas fireplaces are commonly direct vent and offer a sleek aesthetic and advanced fireplace features.
Fireplace Features and Efficiency
When comparing gas fireplaces, consider features such as remote controls, variable flame settings, blower fans, and glass-front versus open-front designs. High efficiency gas fireplaces will recover more heat and lower energy costs. Direct vent gas fireplaces and high efficiency gas inserts often provide the best performance. Vent-free fireplaces are efficient in terms of room heating but may affect indoor air quality.
Converting a Wood-Burning Fireplace
If you have an existing wood-burning fireplace or existing masonry fireplace, you can add a gas fireplace in several ways. A gas fireplace insert or gas log set installed into an existing fireplace opening can convert a wood burning fireplace to gas.
Smoky Mountain General Store offers professionals and products to retrofit existing fireplaces safely, including gas supply connections and appropriate vent systems for direct-vent or B-Vent options.
Installing a Gas Fireplace
Installing a gas fireplace requires attention to venting, gas supply, and local codes. Direct-vent fireplaces need a proper vent system that runs to the exterior, while B-Vent requires a compatible chimney. Vent-free fireplaces require no external venting but must meet local regulations. Installation by a qualified technician ensures safety, maintains indoor air quality, and maximizes performance.
Indoor Air Quality and Safety
Gas fireplaces offer cleaner combustion compared to wood-burning fireplaces, but indoor air quality remains important. Direct-vent gas fireplaces reduce indoor air contaminants because they use outside air for combustion. Vent-free fireplaces may increase moisture and combustion byproducts in the room; if you choose ventless fireplaces, ensure proper ventilation and follow code restrictions. Smoky Mountain General Store provides guidance on choosing the right gas fireplace type to balance heat output with indoor air quality.
Styles and Aesthetics
Gas fireplaces come in many styles to complement traditional or contemporary interiors. From classic gas log sets that mimic a wood-burning fireplace to modern linear gas fireplaces with glass and stone surrounds, there’s a gas fireplace style for every home. Consider options like glass-front inserts, ceramic or realistic gas logs, and custom surrounds to match your décor.

FAQ
Q: Can I add a gas fireplace to my existing wood-burning fireplace?
A: Yes. A gas fireplace insert or gas log set can be installed in an existing masonry fireplace. If you prefer a sealed system, a direct vent insert may be recommended. Smoky Mountain General Store offers many options.
Q: Are ventless gas fireplaces safe?
A: Vent-free fireplaces burn gas efficiently but do not exhaust the outside. Some areas restrict vent-free gas fireplaces because of indoor air quality concerns. Check local codes and consult with Smoky Mountain General Store specialists.
Q: Which is best — direct vent or B-Vent?
A: Direct vent fireplaces are generally more efficient and better for indoor air quality because combustion air and exhaust are sealed from the interior. B-Vent works well with existing chimneys but is typically less efficient.
